Happy Masks Review – Happy Masks Pro and Ultra

Happy Masks is a U.S.-based company that appeared on my radar while I was researching nanofibre masks. Soon after, a few readers contacted me asking if I could do a review as they were interested in purchasing the mask. Today, after using the masks for a few years, I am happy to present my review of the Happy Masks Pro and Happy Masks Ultra series.

Happy Masks advertise some quite exciting features. The most important of these features is the very lightweight and highly breathable nanofibre filter that retains efficiency even after being washed. The mask also has a beak design, so it doesn’t interfere with speaking and has very good test filtration results.

With these features, I quickly became interested in the mask and wanted to try it myself. I initially tried the Happy Masks Pro in 2021, and in that review, I discovered some issues with the mask models at the time. Since then, I’ve used a range of different masks from Happy Masks as they’ve been improved and built upon.

Where Happy Masks originally began with the Pro and Base series of masks, the Base has been replaced with the Ultra, and the Pro has also seen significant improvements. If, like me, you have tried masks from Happy Masks previously, there’s a good chance that the recently updated models perform better – especially regarding fit.

If you’ve tried these masks, I would love to hear your thoughts in the comments below. I always value other opinions and would be interested to see what others have experienced with Happy Masks. With that being said, let’s jump into this Happy Masks review!

Please note: There is some confusion as there are two mask brands – Happy Masks and Happy Mask (no plural). This review is for Happy Masks, found at I have NOT reviewed masks from

Happy Masks Filter Design

Fit and filtration are the two most important factors of any mask, and they both go hand in hand. Filtration testing is essential to see how effective a filter actually is, and a good fit is required to make sure that air actually passes through the filter.

In this section, I will discuss the lab results that Happy Masks provided me. I will have a look into what they mean and how they can be interpreted. If you’re interested in taking a look at the test results for yourself, you can do so on Happy Masks technology page.

It’s important to note that this testing applies only to the filter, not the mask itself. Further, as previously mentioned, it’s vital to make sure that the mask is fitted as well as possible to minimise leaks – leaks indicate that not all of the air is being filtered, meaning that you are breathing unfiltered air.

Happy Masks have one significant advantage when it comes to filtration, and that is because the masks use a nanofibre membrane filter. Nanofibre filters can be found in some reusable cloth masks, but they are still much less common than cheaper-to-produce melt-blown filters. 

Meltblown filters are cheaper to produce and easier to make, and that is why the majority of masks on the market rely on them. However, they also rely very heavily on electrostatic attraction – something that can be lost due to various factors, such as moisture in exhaled air. 

Happy Masks Mask

On top of this, Meltblown filters can’t be washed using traditional methods and require very specific cleaning to retain filtration efficacy. Even then, they drop in efficacy far more quickly than nanofibre filters which rely much more on mechanical filtration mechanisms

I recently interviewed Revolution Fibres on the benefits of nanofibre filters, and I recommend reading that article if you would like to learn more. In brief, nanofibre filters typically are usable for longer, have much lower breathing resistance, can be washed more easily, and retain more filtering efficacy through washes. Due to these benefits, the use of a nanofibre filter in Happy Masks is very advantageous.

In fact, I was shown test results from OSH, a Taiwanese respirator testing laboratory. In the tests, unwashed (new) filters were compared to filters that had undergone 50 wash cycles per the manufacturer’s cleaning instructions – the masks were washed for 3 minutes in water with a drop of dish detergent. 

The masks were then removed from the water, rinsed, and left to air dry. 5 masks were tested this way, and each was exposed to this process 50 times. These five masks were then tested against five masks that had not been washed. The results showed no difference in filtration efficacy between the unwashed masks and those washed 50 times. 

This is a very impressive result, and it aligns with what I expect from nanofibre filters. Since the filter is built into Happy Masks (and can’t be removed or replaced), this is especially important. The filter is suitable for around 250 hours of wear and can be washed in detergent when needed. 

Where I generally recommend against washing masks whenever possible, both the Happy Masks Pro and Ultra series are safe to wash following the recommended procedure.

Happy Masks Filtration Efficiency

When it comes to filtration testing, the Happy Masks Pro and Ultra have undergone a range of testing. The masks have been tested for NaCI (a particle filtration efficiency test), BFE (bacteria filtration efficiency), and VFE (viral filtration efficiency). Nelson Labs carried out BFE and VFE testing, and NaCI testing was done by both Nelson Labs and TTRI (Taiwan Textile Research Institute). 

For both the BFE and VFE tests (with five samples tested), the filter achieved > 99.9% filtration. This was carried out using particles with a mean particle size of either 2.8μm or 3.1μm at a flow rate of 28.3 litres/minute. In all of the VFE tests, there were no detected plaques downstream of the mask.

This is an impressive result, and it places Happy Mask above other reusable cloth masks, such as the Cambridge Mask Pro. However, it’s important to note that both BFE and VFE tests are significantly less challenging than most NaCI test standards. Not only are the particles far larger, but the flow rate is also significantly lower.

On top of this, since bacterial and viral particles cannot move unassisted, worst-case PFE testing is more important. If a mask, respirator or filter performs well in particle filtration efficiency tests, these results will also apply to bacterial and viral particles, and therefore, these more stringent tests are far more important. Let’s take a look at Happy Masks PFE test results!

Four samples were tested in the NaCI testing carried out by TTRI, achieving an average filtration rate of 99.24%. The lowest recorded result out of the tested samples was 98.92%. This testing was conducted at a flow rate of 28l/min with a particle size of 0.1μm.

Test TypeFiltration
NaCI (TTRI)≥ 98.92%
VFE> 99.9%
BFE> 99.9%

However, this particle filtration efficiency testing was carried out as per ASTM F2299-2017, which keeps the same flow rate as the previous BFE and VFE standards. They show the Happy Masks Pro and Happy Masks Ultra are capable of a high level of filtration at lower flow rates, but what about under the more challenging conditions I mentioned previously?

Nelson Labs conducted further PFE testing at a higher flow rate of 85l/min with a median particle diameter of 0.075μm. Five samples were tested under these conditions, and the worst-performing mask had a filtration of 96.18%. Interestingly, two of the five samples had no detected downstream particles, demonstrating a filtration efficiency of > 99.999%.

What does this mean? Happy Masks Pro and Ultra filter > 95% of particles at worst. However, there is a significant variance between each Happy Mask, and some can filter a far higher percentage of particles under the same test conditions.

It’s important to note that masks such as Happy Masks can not replace respirators, and the test results should not be directly compared. Respirators such as N95s undergo more stringent tests, and their testing tends to be far more conservative. While Happy Masks are capable of a high level of filtration, they can not replace respirators.

Due to the nanofibre construction of the filter, the mask is also exceptionally light and provides relatively low breathing resistance. The only other masks I have tried with such low breathing resistance are the Bloo Mask and Airgami, which are incredibly breathable.

Happy Masks Pro Black

While filtration is often the aspect that many customers focus on when purchasing a mask, the fit is just as important, if not more so. A mask that isn’t fitted correctly will not filter the air; in that case, the actual filtration specifications of a mask are useless.

Happy Masks rely on the wire nose-piece and adjustable earloops for a good fit. No foam around the nose area exists, and a secure seal relies entirely on the wire. The ear loops are adjustable and allow for some degree of fitting the mask. While the fitting mechanisms of the mask are very simple, they generally work quite well, from my experience.

If you’ve browsed the Happy Masks store, you will already know that Happy Masks has two mask lines – the Pro and Ultra. While the two masks are largely the same, one of the key differences is in the rigidity and size of the wire nosepiece. The Pro has a rigid piece of wire in the mask’s upper trim. The Ultra, on the other hand, has a thicker, flat piece of wire that I actually found to be less rigid, located just under the upper trim.

Based on the naming of the masks, you would naturally expect the Ultra to be the better-fitting mask. However, I’ve had a better experience with the Happy Masks Pro due to the more rigid nose wire. While I like the flat design of the Ultra mask, and it should seemingly fit better, the Pro’s design provides a more secure seal for me.

Happy Masks Pro

With the Happy Masks Ultra, I have to readjust the nose seal of the mask regularly. This is less than ideal, and I always find myself reaching for the Happy Masks Pro instead. I was curious if this experience was limited to me, so I asked my girlfriend to try both masks and see which fit better. She has a flatter nose and found the less rigid Happy Masks Ultra to fit better.

It’s hard to make broad assumptions based on only two situations – especially when everyone’s face varies so greatly – but this would lead me to think the Ultra is better for people with less distinct facial features. Conversely, the Pro may be the better choice for those with sharper facial features and taller noses.

One of the biggest complaints I had with the original Happy Masks during my initial review a couple of years ago was the length of the wire nosepiece. At the time, it was simply too short to allow for a good fit. Luckily, after hearing the feedback, the team lengthened the wire on both the Pro and Ultra masks. Nowadays, the wire extends about 5cm on either side of my nose. I have no complaints about this length, and it worked well for me.

Before moving on from the wire nose piece, I want to emphasise the importance of flattening the wire before donning the mask. This goes for all bi-fold masks, but it’s key with the Happy Mask Pro. Before you don the mask, you’ll want to flatten the wire to mould it around your nose effectively. Without this action, there will likely be a gap between your nose and the peak of the wire.

Happy Masks Ultra Side View

Time to move on to the second fitting mechanism – the earloops. Both the Happy Masks Pro and Happy Masks Ultra have adjustable earloops, which are identical except for an added stopper on the Happy Masks Ultra. This exists purely to prevent the earloop toggle from being accidentally removed and doesn’t impact fit at all.

Both masks use a relatively thin piece of elastic on the earloops. While this doesn’t look or feel particularly secure, it works quite well in this case because Happy Masks are very light masks that require little pressure to keep them in place. With that said, they aren’t particularly comfortable after long periods of wear.

To achieve a secure seal, I had to tighten the earloops significantly. Thankfully, the toggles are surprisingly secure, and even when I tightened the earloops, they didn’t slip and frequently require readjustments. Occasionally, I would have to tighten the loops again, but this was infrequent and, therefore, only a minor issue.

Happy Masks has three different mask sizes for a range of different facial shapes and sizes. I’ve only used the medium masks throughout the years I’ve used Happy Masks, but these have always fit me well. Make sure to follow Happy Masks sizing instructions before purchasing a mask to ensure you get the best possible fit.

Happy Masks Size Guide

Overall, I’ve been able to achieve a good fit with the Happy Masks Pro, and that’s the mask I will stick with. While I can’t remove leaks with the Happy Masks Ultra, I believe people with a flatter nose may be able to achieve a better seal with this model. Since fit varies greatly, I would love to hear from you. If you’ve tried either Happy Masks Pro or Happy Masks Ultra (or both!), what are your experiences?

Happy Masks Design

Happy Masks’ biggest strength is comfort. Both the Pro and Ultra are lightweight masks that are very breathable. They’re masks that can easily be donned and doffed, and wearing these masks feels much more freeing than wearing a larger mask such as the AirFlex Mask or a Cambridge Mask.

At low breathing rates (such as when resting or when lightly active), Happy Masks’ breathing resistance is negligible. At 6l/min, an ICS laboratory test found the breathing resistance to be only 0.6mmH2O. This is incredibly low, and while it’s only at 6l/min, a normal minute volume for humans is 5-8 l/min.

Even when lightly or moderately active, the breathability of both Happy Masks models is exceptional. There is minimal resistance, and I don’t think anyone will have any issues with the breathability of these masks. With that said, I believe the breathing resistance on the Happy Masks Ultra is slightly higher due to the more rigid materials used.

Happy Masks Filter

Since the masks are very breathable, they are also great at expelling warm air and humidity. While the interior of the mask will inherently be warmer than ambient temperatures and will naturally retain some humidity, I had a far more comfortable time with the Happy Masks Pro and Ultra than masks such as Cambridge Mask.

Unfortunately, both the Happy Masks Pro and Ultra suffer from some filter collapse, and I regularly find the inner layer of the mask sucked towards my mouth. While it isn’t as severe as some masks (such as the Strapless N95), it’s enough to be annoying. For this reason, despite the great breathability, I would not recommend Happy Masks for exercise.

Regarding the wire nosepiece of the mask, I have no comfort issues to note. The wire does not dig into my cheeks and isn’t otherwise uncomfortable. Both are comfortable whether you opt for the more rigid nose wire of the Pro or the flatter, more malleable wire of the Ultra.

Happy Masks earloops

The earloops on both masks are comfortable for shorter periods or when worn loosely. However, they can cause pain behind the ears after long periods of wear. This is somewhat offset by how light the mask is, though, and I found the pain to be less than some other masks that rely on ear loops. However, I still prefer masks that use neckbands and headbands.

Also worth noting is that the materials used don’t appear to have strong scents. While it may sound unusual, I’ve come across many masks that have odd scents when they are new. While these don’t prevent me from wearing masks, they can be uncomfortable when initially donning them. Luckily, Happy Masks don’t appear to have any such issues.

Overall, Happy Masks are comfortable masks, and I would be happier wearing these masks for long periods than most other masks. While both masks suffer from some filter collapse and can be uncomfortable when the earloops are tightened, they are more comfortable than the competition due to their exceptional breathability.

Lifespan & Cost

Happy Masks Contents

Happy Masks do not feature removable filters. As such, the filters can’t be replaced, and the whole mask should be replaced once it gets damaged or reaches the end of its lifespan. Fortunately, due to the filter design, the mask can be washed.

When washing the Happy Masks Pro, make sure to hand wash. These masks should never be machine washed as they are delicate and require soft handling. For the exact washing procedure, Happy Masks has a short one-minute Youtube video explaining the process.

If you purchase the Happy Masks Ultra, you can machine wash the masks on a delicate cycle in a mesh bag. However, you will want to avoid machine washing where possible as it’s more likely to damage this mask. With this in mind, I recommend handwashing the Happy Masks Ultra when possible.

The masks were tested for filtration efficacy after 50 washes, and there was no drop in filtration. This means that provided you are washing the mask, as the video shows, there should be no need to worry about losing efficiency. However, if the mask gets damaged or the filter becomes difficult to breathe through, the mask should be replaced.

Further, Happy Masks should be replaced after 250 hours of wear. If you wear the mask for 2 hours daily, this equates to around four months of wear. While this does depend on local air quality conditions, you should be able to expect to get around this lifespan from each Happy Mask.

The masks cost $24 for the Pro Series, and the Ultra Series cost $27. This means you are looking at around $1 per 10 hours or 10 cents per hour of wear. In the long run, this will be much cheaper than disposable masks. Even better, Happy Masks have significantly better filtration efficacy than most disposable masks.

Happy Masks Review Breathesafeair scaled

I believe that nanofibre filters are the way of the future regarding masks and filtration. I am very happy to see this technology being used in Happy Masks, as it’s still much less common in reusable masks than melt-blown technology. Due to this newer technology, Happy Masks have large advantages regarding breathability and reusability.

Happy Masks are also very light and are very easy to wear. This is one of the least intrusive masks I have worn, and it’s easy to put on for a short trip outside, such as when I go shopping. On the other hand, it’s also proven quite comfortable over longer periods of wear.

I am also very happy that Happy Masks was willing to listen to customer feedback and improve their masks based on common complaints. They were quick to act on feedback about the wire nose-piece and to try to solve the issue. While I still encounter leaks around my nose on the Happy Masks Ultra, the fit of the Happy Masks Pro is significantly better than on the previous iteration of the mask.

While the mask suffers from filter collapse, this is an acceptable trade-off for me as I still find Happy Masks among the most comfortable masks for day-to-day wear. With the Pro, I am also confident in the fit and, therefore, the protection I am receiving, making the Happy Masks Pro a good mask choice for me. However, as mentioned previously – you may find the Ultra to fit better, especially if you have a flatter face than me.

Finally, I also want to mention that this mask would be a good choice for children. Realistically, children’s masks are hit and miss because you will never be able to achieve a leak-free seal on children – they are just too active and love to touch/adjust their masks. Happy Masks are relatively loose-fitting but can still achieve a decent seal.

  1. Hi Ethan,
    Thank you so much for your reviews. Logical and organized. Very refreshing read.

    I have a question- i live in an area that gets hot in the summers. 95° – 110F, 35- 43 C,. Do you have experience with wearing masks in heat? What masks might you reach for on a hot day. This Mask had the word Light quite a bit. We can wear valve masks outdoors atm. So I might try one of those also. I am interested in any light you have on the subject.

    Thank you so much!

    1. Hello Jeanine,

      Thank you for your kind words! I do have some experience wearing masks in heat – Seoul summers can reach about 40 degrees and are often mid-30s (celsius).

      On a hot day, I would reach typically reach for a lightweight mask with good breathability such as the Bloo Mask (I have a review of that mask on this blog). The issue is, I believe that mask still only ships in NZ and Australia. While I haven’t had a chance to try Happy Masks in summer yet, they feel similar to the Bloo Mask in many respects and, as such, I believe they would be a good choice. Happy Masks did leak a bit more than Bloo Masks, but this will differ from person to person – I’ve also been told they are working on resolving this issue.

      Valves do add breathability, but I still find a better filter makes more of a difference (this is why I would personally use a nanofibre mask. Perhaps Happy Mask, Metamask, or Bloo Mask. I am sure there are other nanofibre masks out there too). If you do want to try a mask that uses valves, I would try the AirFlex or Urban Air 2.0 as they both have dual-valve designs and should (in theory) perform better in high temperatures.

      Unfortunately, I honestly don’t think there is any mask that is comfortable for high temperatures. If there are, I haven’t come across them yet! There are definitely some that are more comfortable than others, however. To answer your question, I personally would reach towards a Bloo Mask but due to the limited availability, Happy Masks are the closest in design. If not Happy Masks, I would look for another mask that uses a nanofibre filter (I know Metamask and Halo Mask do).

      I hope this helps! If you have any further questions please feel free to ask.


      1. Thanks Ethan for your thoughtful response. You verified what I was thinking. So I will order a Happy Mask and a Metamask. I will try the links on your site for ordering. Thanks again for all your work! Best wishes for health, happiness to you and yours!

  2. So I ordered two happy masks after measuring and they did not fit well at all. I called the company and they would not make things right. They offered me 10%. So I would have ended up paying a little over $100 for 2 masks that I could wear. No thank you! I am very displeased with the CS of happy masks. On the other hand the masks seem like good masks.

    1. I am sorry to hear to hear you had a bad experience. I wanted to point out that there are 2 companies with similar names (one is Happy Masks and the other Happy Mask (not plural). Since the Happy Masks reviewed on the blog are about $25 each, I am wondering if you ended up at the other site since you paid a lot more. I just wanted to comment since the Customer Service that I have encountered at Happy Masks has been nothing short of stellar. I had a hard time finding a mask my son would wear and needed to try one of their masks soon for an upcoming doctor appointment- they expedited my shipping free of charge to make sure it would make it in time. That impressed me so much and we have been loyal customers ever since.

      1. Thank you so much for pointing this out Amy. I had no idea about this other website. I have updated the article to mention that the review is for Happy Masks from

  3. Very unhappy with the mask. The nose wire is to thin and flimsy. It is lower than the top edge of mask and I can’t vet a decent seal. I will not wear the mask. There is too much leaking around nose. If a mask does not fit properly, it is useless no matter how many filters it has.

    1. Hello Anna,

      I am sorry to hear about the bad experiences that you have had. I wonder if you got the newer version of the mask? I have found that that definitely improved upon the leaks for me.

  4. Same as above. I ordered 6 due to an upcoming trip and based solely on word of mouth recommendations. I am beyond disappointed. The seal is completely inadequate rendering the high efficiency filtration useless. Unlike you, I have found masks manufacturers who were able to address the gaps around the nose, and this mask could do it as well (I’m guessing) if they used stronger nose wire. It’s not rocket science. Otherwise the mask is great, but given that significant gaps means you’re not protected, not protecting others, then again it’s useless. $25 is too much to spend on a useless mask. I’m guessing I’ll have to eat the $160 I just spent, as this company has (from online search) a bad reputation for customer service.

    I don’t recommend this mask, and I’d suggest anyone who is promoting is putting their reputation for honesty and reliability at risk. I’d go as far as to say it’s a rip off, and false advertising.

    1. Hello Rita,

      I am sorry to hear that you have had such a bad experience with the mask. Thank you for sharing your experiences – I, and other readers, value them greatly. I hope that from the opinions shared we can get a general picture of each mask’s strengths and weaknesses.

      However, I stand by what I said. I mentioned multiple times in my article that my writing is based purely on my experiences – I also mentioned that the mask won’t fit everyone as well as it did me. I don’t know what to tell you, other than Happy Masks really do fit me well. I’ve tried many masks (I hope this website can attest to that fact), yet I’ve settled on Happy Masks as my daily masks due to how well they fit me and how light and breathable they are. I don’t know whether or not you meant to target me in your last sentence, but it feels like you did so I wanted to address that.

      Again, I really do thank you for sharing your experiences, I hope they are valuable to other readers. In the future, I will try to get more people to test the mask before writing a review (to test the fit across more people). I try very hard to make it clear that parts of these articles (such as the ‘fit’ section) are based purely on my experiences, with my face shape.

  5. Loving your reviews.

    I am a high school teacher returning to the classroom in a couple weeks. I’m looking for high efficiency filtration w/o a valve that will also allow me to speak as clearly as possible to my class. I came across this review because you mentioned Happy Masks are easier to talk with. Would this be one you’d recommend in my case? Of course I understand fit, etc. is personal and not something you can speak to.

    Many thanks for the thoughtful and thorough reviews.

    1. Hello Dustin,

      Thank you for your kind words!

      Happy Masks are a fantastic choice when it comes to voice clarity. There aren’t many masks out there that perform as well as them when it comes to that aspect. I’m only hesitant to recommend them after reading the feedback of other users in the comments (which I recommend that you read if you haven’t already) regarding the fit.

      When it comes to voice clarity my usual recommendations would be Happy Masks, Primal Wear Masks (I actually have tried this mask but never published a review), or Styleseal. Styleseal sits closer to the face, but the mask is quite sturdy so I found it to perform well in this respect.

      I hope this helps! If you have any further questions please feel free to ask.

  6. In order to solve the problem of air leaking around my nose, I sewed an additional wire on my happy masks. I used the wide plastic covered wire from a bag of coffee beans, but I suppose there are actual nose wires one could purchase. This has helped me get a great seal.

    I am curious to try a newer mask with the longer wire. I wonder if the mask I got for my son in early June is the newer model. It actually slips off his nose frequently. His older one never did that.

    1. i had same issue with my sons, i still haven’t received mine. not sure why they misrepresent the mask to have no leaks, but it is def. a flaw.

  7. My husband and I each have a Happy Mask. We are delighted with them. Neither of us have experienced any problem at all with leaking air around our noses. I wear glasses and they don’t fog up, which means there is no air leaking. 🙂

    Prior to the Happy Mask, I had purchased a Castle Grade mask, which is silicone and has disposable filters. It’s a good mask, but it’s uncomfortable (especially in the summertime), looks odd, and I hate fiddling with the filters. Furthermore, it is bulky since it doesn’t fold up.

    I can put my Happy Mask in my pocket. I can slip it on in a second or two. It doesn’t leak. I could wear it for hours if I had to. I am going to order some more of them. We got one each just to make sure we liked them before getting more.

    Thank you for the review.

  8. the company is awful in cust svc. you don’t get a mask in 3 months and then when you want to cancel they threaten you fees b/c they change your order into a “pre-order” , yeah right. total scam company; should be shut down.

    1. Hello Alex,

      At this point, I am very confused about Happy Masks. It seems that a lot of readers have amazing experiences with their customer service while others have terrible experiences. Could you share the URL of the website you purchased from? There seem to be a few with very similar names.

  9. I love the original Happy Masks with the small nose piece below the trim, but hate the new design. After July they changed the malleable nose piece to a rigid and extra long one under the eyes that is very uncomfortable (who wants to feel something hard under your eyes all day), causes rubbing, and leaves gaps any time you move your face/mouth. The original design provided a good seal for me and my kids, but the new design is so stiff it’s impossible to keep a good seal. Additionally, the new mask feels so stiff overall that it’s a constant reminder that you are wearing a mask. The original masks have a soft touch.

    1. Hello,

      That’s very interesting. I’ve found the new design to be much better in every way except that it seems to lose more structural rigidity after washes than the original does (this leads to more severe filter collapse). I’m sorry to hear that the new mask is so much worse than the older one, I wonder if perhaps they should sell both alongside each other. However, I guess that would cause production issues.

      Thank you for sharing your thoughts!

  10. Hi, what would be your go-to mask recommendation for wearing on long haul flights?
    I think most important feature would be breathability (not feeling claustrophobic/hot/mask collapsing)?

  11. Was very disappointed! In the mask !
    My grandkids said it was uncomfortable and they had a hard time breathing in it !!
    Customer service was rude and very dismissive to me .
    Would not recommend buying this mask They also need to hire better customer service people.
    All around bad experience and product

  12. We love Happy Masks in our house. My 5 and 7 year old wear them all day at school. The fit wraps nicely around their face shape and stays in place. My kids talk and run with these and I wore one to an intense gym class with no trouble breathing. The shape keeps my kids from chewing on the masks. I find them more comfortable than KN95-style masks, but with the same filtration in lab tests, and washable. Great for plane flights too. It’s true there is a waitlist to get these, but the company tries very hard to get them to customers, and has always shown me good customer service. Fit is personal of course. We only wear Happy Masks!

  13. Question re the 99.9% particulate filtration level. Your review states: “…BFE and VFE tests (with five samples tested), the filter achieved > 99.9% filtration. This was carried out using particles with a mean particle size of 3.1μm at a flow rate of 28.3 litres/minute.” HappyMask’s website also compares it to N95, implying it is BETTER than an N95. BUT N95’S are rated based on their ability to FILTER 0.3 MICRONS, & Covid particles can be as small as 0.3 microns. SO IF THE HAPPY MASK IS TESTED & RATED FOR 3.1 MICRON PARTICLE SIZE–NOT 0.3 MICRONS–THEY ARE NOT ANYWHERE NEAR AS EFFECTIVE AS AN N95 FOR FILTERING OUT THE SMALLEST COVID VIRUS PARTICLES !! Am I right, or am I misunderstanding something here?

    1. Hi Terry,

      Thanks for your question. You are right in that BFE and VFE tests are far less challenging than PFE tests (especially the NIOSH tests, which are considered very challenging). However, Happy Masks has had a range of tests – not just BFE and VFE. In fact, the PFE has been tested by Nelson Labs, SGS, ICS and TTRI. The Nelson Labs test is the quoted test where the masks achieved > 99% PFE filtration.

      I don’t have the lab tests on hand currently, so I can’t confirm the PFE testing standard that Nelson Labs used to challenge Happy Masks. However, I would guess the testing was carried out with the ASTM F2299 methodology. On the Happy Masks website, it looks like the particle size used was 0.3 microns – the same as the NIOSH tests and at the same flow rate. While this test isn’t as challenging as NIOSH’s test (, it is a common PFE test and shows that Happy Masks are highly capable of filtering particles as small as 0.3 microns.

      Therefore, you are right that BFE and VFE tests are carried out against much larger particles. However, Happy Masks have also been tested against smaller particles (including 0.3 microns) in other (PFE) tests and achieved > 99% filtration.

      I hope this helps!

      1. I love Happy Masks. My family has used these masks exclusively after discovering them mid-pandemic. They’re the best for kids and comfortable for all day needs and flights. We’ve only ever used the pro version and have had some issue with the nose piece breaking but they’re used a lot and washed weekly so I think it comes with the territory. Thanks for the comprehensive review.

  14. I recommend Happy Masks very highly for sports and exercise! I’m a high level figure skater who also does beginner gymnastics. The lightness of the masks, the breathability, and the ability to stay in place are very important when you are rotating and flipping, and Happy Masks excel at all three of those. Most importantly to me, Happy Mask’s filtration isn’t affected by moisture from sweat so they remain as efficient when sweating heavily (unlike other masks!). I move my Happy Masks through a life cycle: high level exercise first, then when I start to feel some resistance they are moved into the grocery store/doctor’s office/etc. rotation, then when resistance becomes noticeable in those settings they are moved into the dusting/mowing rotation.
