14 Best Reusable Masks – Cambridge Mask Alternatives

Respro respirator

Although disposable masks are handy, they are also expensive, environmentally harmful, and require planning to pre-purchase.

If you feel this way, a reusable mask is extremely useful. Not only are they cheaper over the long run, but they are often more comfortable and more environmentally friendly.

These days, there is a massive variety of reusable masks out there, and a large number of them are very good. The most popular tend to be Cambridge Mask, Vogmask and Airinum, however, they aren’t the only options!

Especially currently, many of these brands are out of stock. It has led to many people asking the question ‘what are the best Cambridge Mask alternatives?’ and ‘what are the best Vogmask alternatives?’.

In this article, we will have a look at some of the best reusable masks on the market. Most of these masks are quite well-known, but there might be a few that you haven’t heard about before!

Before I begin listing the best reusable masks I want to clarify a few things.

  • Masks on this list are intended for general (public) use and should not be used in professional settings. If you are in a professional setting, get training before deciding on a mask or respirator.
  • These masks are generally intended to protect against typical outdoor air pollution. That is to say, they protect against fine particles. If you need protection from a specific gas or particle, make sure to do research and to purchase the right mask.
  • No reusable mask or respirator is effective unless it is fitted properly. While fit-testing requires professional training, some level of protection can be achieved by doing pressure checks and following the fitting steps

Masks with valves should be AVOIDED for pandemics and virus protection. It is important to only use masks WITHOUT valves if you are looking for such a mask.

Why Pick a Reusable Mask?

Aropec Anti Viral Review

Looking for an anti-viral mask? Check out my Aropec Anti-viral mask review.

Before we go over the best reusable masks, we first need to discuss why reusable masks are better. There are a few obvious factors, such as that they are more convenient and less environmentally harmful, but there are a few other elements that you may not have considered!

  • Reusable masks are cheaper. Although they require more initial investment, an average reusable mask lasts for 150-300 hours. Disposable masks normally only last for around 8 hours each. If the average disposable mask costs $3, then you are looking at over $100 for 300 hours worth of disposable masks.
  • No need to worry about fit. When purchasing a disposable mask, you always have to worry about the fit. Every mask is different, and not all will fit you. With a reusable mask, once you find one that fits you never need to worry again. Just purchase the same mask again in the future!
  • Reusable masks can be washed. This means that you can keep them clean and also that they are more environmentally friendly.
  • You can pick a mask design that suits you. Whether you want something subtle that blends in, or something that stands out, you can find a design that you like with reusable mask.

Best Reusable Masks

There are many different reusable mask companies out there, and I couldn’t include them all on this list. I will be making sure to update this list in the future and to add new companies when I encounter them.

However, I wanted to include companies that have a relatively strong international presence. Many countries have domestic reusable mask producers, but many of these (especially in the cases of countries like Korea and China) don’t ship internationally.

If there is anything that you would like to see added to this list, please leave a comment and I will add the mask when I can. Currently, all masks on this list have individual reviews. Please feel free to check out the full reviews for more details.

1. ConceptAR

Conceptar Pollution Mask review

Conceptar (also named AR Facemask outside of the U.S/Canada) is one of my favourite cloth masks for everyday wear. There are variants both with and without valves, and the mask features replaceable filters that last around 2 weeks each. The replacement filters are moderately priced and very easy to change.

Currently, the mask has only had third-party testing for bacterial and viral filtration. In both of these tests the filter received a score of over 99%. The worst case filtration for bacterial and viral was 99.8% and 99.7% respectively. However, this mask currently does not have particle filtration results.

The mask also features ViralOff, a fabric coating that allows the mask to kill over 99% of viruses in two hours. This is a great addition and allows the mask to be washed less frequently as it can be worn again after sitting overnight.

Pros

  • Over 99% filtration of both viral and bacterial particles
  • Easily replaceable filters
  • Both valve and non-valve variants available
  • Simple design that works with many outfits
  • Valve is also filtered (both inhaled and exhaled air will be filtered)

Cons

  • The filter can be easy to breathe in
  • More expensive than some of the cheaper masks on this list
  • No third-party particle filtration testing

2. O2 Canada

Curve Canada Respirator

O2 Canada and Gill Mask are unlike other masks on this list in that they aren’t cloth masks, but rather plastic/silicone respirators. While the Curve 1.2 provides significantly more breathing resistance than most cloth masks, it also offers great filtration and sealing.

The Curve Respirator features ≥ 99.9977% viral filtration (VFE, 2.7μm), ≥ 99.99983% bacterial filtration (BFE, 3.2μm), and ≥ 87.8% particle filtration (PFE, 0.26μm mass median diameter). However, the PFE tests will soon be updated with new results from further testing.

The biggest benefit of the Curve 1.2 is that it uses a silicone seal to prevent leaks. The mask is quite small and I found it to be the best fitting silicone mask that I have used. However, I have heard that people with larger faces have had trouble fitting the mask.

The mask uses an ear-loop design, and while this design means that the mask stays in place, it can be quite uncomfortable over long periods. There is a sports head-band available and this accessory will make wearing the mask much more comfortable.

Pros

  • High filtration efficiency
  • Good fit for people with smaller faces
  • Extensive testing (filtration, fit factor, inward leakage)
  • Modular design allows for easy replacement of parts
  • Uses a valve for lower breathing resistance

Cons

  • More expensive than some other masks
  • Fitting can be difficult on larger faces
  • Ear-strap design is uncomfortable over long periods

3. Re-Mask

Re Mask Pro with Valve

Re-Mask is a relatively new entry to the reusable mask space. However, despite being new they have a great line-up of masks for a variety of different purposes. Further, the viral, bacterial and particle filtration levels have all been tested by third part labs (Nelson Labs).

The filter is capable of filtering 99% of particles, 97% of bacteria and 99.9% of viruses at the MPPS of 0.3μm. That means that the filters in Re-Mask are some of the most capable on this list.

There are three different models – the Pro, which has a valve and is aimed at pollution, the Casual which allows the user to replace the filters and is aimed more at viral and bacterial filtration (with no valve), and the Sports Series. A cheaper mask intended for families.

The masks are very light and comfortable to wear even in warmer conditions. The Casual Re-Mask also allows the user to replace the filters when needed, meaning that this mask is reusable for many months or potentially even years.

Read more – Re-Mask full review

Pros

  • Some of the best filtration qualities out of all masks on this list.
  • Many different designs, including valve and valve-less.
  • Ships to most countries.

Cons

  • More expensive than some options on this list.
  • Harder to achieve a proper fit with.
  • Ear-strap design can be uncomfortable for long periods of wear.

4. Gill Mask

Gill Mask Design

Gill Mask is one of the more interesting masks that I have recently reviewed. This silicone mask is designed with three main goals in mind: to decrease cost, to decrease waste, and to be easily cleanable.

The Gill Mask allows the user to choose which filter they want to use. However, unlike most masks, these filters can be almost anything – they aren’t brand or size specific.

For example, if you are only looking for droplet protection or protection from larger particles, a surgical mask can be cut down to provide 4-6 filters for the Gill Mask. This not only decreases waste, but also is far cheaper over the long term.

For better protection, filters such as the Earth Filter can be used (after being cut down to size). Gill Mask also offers their own filters. Finally, the mask is also very easy to clean due to the easy removal of the filters and the plastic design. A children’s model is also available.

Read more – Gill Mask full review

Pros

  • Almost anything can be used as a filter. This allows the user to choose which type of filter they need.
  • The silicone design allows for a great fit.
  • The mask is very easily cleanable.
  • Filtration depends on which filter is used. Nearly every type of mask/filter can be cut down and used in Gill Mask.
  • Head straps are very comfortable.

Cons

  • Mask can be difficult to breathe through due to small filter.
  • Not a good mask for exercise due to breathing difficulty.
  • Bigger design that is conspicuous.

5. Totobobo Mask

Totobobo Children Mask

Totobobo is a company based in Singapore that offers one of the most unique masks on the market. The first thing that stands out about this mask is the look – it’s transparent apart from the filters.

The transparent and plastic design of the mask offers many unique benefits. Not only can you self fit-test the mask (this is the only mask to offer such a function), but you can easily clean it. You can even heat the mask up to mould it to your face!

Totobobo has many unique features and it is one of the most interesting masks on this list. if you don’t mind the look, then this is one of my personal recommendations. It’s one of the best fitting masks that I have ever tried.

Read more – Totobobo full review

Pros

  • The only mask on this list that allows for self fit-testing
  • Adjustable in many different ways. This allows for users to create the perfect fit
  • Filters are easily replaceable and cheap to replace
  • Different sizes for children all the way to adults
  • Easily washable

Cons

  • The look of the mask isn’t liked by everyone
  • Not all filters have lab results yet. However, the F94 and F96 filters have full test results

6. Airinum Urban Air Mask

Airinum Urban Air Mask 2 Review

The Airinum Urban Air Mask has recently been updated to the Urban Air Mask 2. This new model has improved upon the previous and made one of the most popular masks even better.

This mask is a premium mask and it is more expensive than many in this list. However, it does also offer some unique benefits. Firstly, the dual valve design (the mask also comes with valve-stoppers for virus prevention) allows for low breathing resistance.

Secondly, the mask uses Polygiene’s Stay Fresh technology meaning that the mask should stay fresh as odour-causing bacteria won’t be able to grow on the surface. On top of this, the mask also comes with an included headband.

Most importantly, the mask has extensive testing from Taiwan Textile Research Institute, RISE (Research Institutes of Sweden, Jiangsu Quality Supervision and Inspection Center for Special Safety Protection Products and CNTAC Testing Service Co. in Foshan. These show a high filtration rate of > 98%.

Read more – Airinum Urban Air Mask 2 full review

Pros

  • < 95% filtration on all particles tested (< 98% on larger particles)
  • Low breathing resistance due to dual-valve design
  • Included headband to alleviate pain on ears
  • Stay Fresh technology to reduce smells

Cons

  • More pricey than many masks on this list
  • Even when using valve-stoppers, mask may be identified as a valved-mask
  • Filter replacements are also expensive

7. MetaMask

Metamask Flower of Life Mask

Metamask is a mask brand based in Bali that uses filters made by Revolution Fibres in New Zealand. The filters used are the same as the mask below this, the Bloo Mask.

The filters have ≥ 98.5% BFE, ≥ 97.6% VFE and ≥ 97.5% PFE. These are high filtration results and mean that the filter is capable of filtering the majority of particles breathed in by the wearer.

Metamask uses a chin-wrap design that allows for a better fit. On top of this, it features a dual-filter media design that prevents the wearer from being able to suck in the filter or mask when breathing. This is a welcome addition!

Finally, perhaps the biggest appeal of Metamask is that many of their mask designs use natural materials. They offer organic hemp and linen masks among others. For people with sensitive skin, Metamask might be a mask worth checking out.

Read more – Metamask full review

Pros

  • Masks made from natural materials
  • High filtration (> 97.5% on all tested particles, 0.1μm, 0.3μm, 0.5μm and 1μm)
  • Dual-filter media design that prevents filter from being breathed in
  • Chin-wrap design for better fit

Cons

  • Can be hard to achieve a good fit around the nose
  • Natural fabrics mean less water/moisture resistance
  • Fabrics can smell a bit initially

8. Bloo Mask

Bloo Mask Comfort

Bloo Mask is a brand based in New Zealand. These masks are extremely light (at only 10 grams) and have an expected usage period of around 200 hours. They also offer exceptionally low breathing resistance.

The masks offer > 97.5% filtration against all tested particles (0.1μm, 0.3μm, 0.5μm and 1μm). On top of this, they also offer >97.5% filtration against both viral and bacterial particles. I covered the filtration characteristics of the mask more in my Bloo Mask review.

These masks do not currently hold an official rating. However, the filter has had third-party testing. The addition of a chin-wrap also means that the mask provides a comfortable fit.

Overall, this is the lightest and easiest mask to breathe through that I have ever tried. Although the lifespan of the mask is around 100-200 hours (from my experience), the masks are very affordable.

Read more – Bloo Mask full review

Pros

  • Good filtration ( > 97.5% on all tested particles).
  • Very easy to breathe through
  • Exceptionally lightweight
  • Fashionable but doesn’t stand out too much

Cons

  • Shorter lifespan compared to many other masks on this list
  • Currently does not hold official certifications
  • Shipping is currently limited to a few countries (New Zealand and Australia)

9. Mau Mask

Mau Mask Colorful Design

Mau Mask is a company that tries to combine fashion and protection. Where many other fashionable masks provide little or no proven filtration, the Mau Mask uses filters that have been tested by third-party companies.

The masks use no valve, so they are a good choice of protection when air needs to be filtered both ways. However, this means that they can have slightly higher breathing resistance and interior temperature when used for protection from fine dust.

The mask has an average filtration of 99.47% of particles at 0.1μm. This puts it among the higher filtration masks in this list. The filters are also replaceable, meaning that the mask can be used for many months provided that it is cared for.

Read more – Mau Mask full review

Pros

  • High filtration mask
  • Uses replaceable filters that can be changed by the user
  • Fashionable designs
  • Well fitting for average adult faces

Cons

  • Only available in one size
  • The filter doesn’t cover the whole interior of the mask
  • Fitting this mask can be hard as it is a looser-fitting mask
  • Some of the designs may be too flashy for some people.

10. R-PUR Nano Light

R Pur Nano Lite Review

The R-PUR Nano Light mask is a bit different from most other masks on this list as it fills a different market segment. This mask is perhaps the most premium on the list, and this is reflected both in the price and quality.

The Nano Light is designed with exercise in mind, and this can be seen in many of the design choices of the mask. Firstly, the mask does feature a valve for lower breathing resistance. It also has a very high filter surface-area and a dual head-band design that allows for firm fitting.

The mask has been tested on a range of face shapes and achieved over 99.8% filtration in hermeticity tests. Since most masks only have filter results, the testing carried out by R-PUR is comparatively thorough. If you are looking for a capable mask for exercise then this is a good choice.

Read more – R-Pur Nano Light full review

Pros

  • High filtration results across a range of subjects
  • Very firm fitting
  • No pressure on the ears due to the head-band design
  • High filter surface area, allowing lower breathing resistance
  • App to track filter lifespan

Cons

  • Expensive base price and filter cost
  • Very large, this mask is not subtle
  • Only valved variants available

11. Aropec Reusable Face Mask

Anti-Viral Mask Aropec Review

The Aropec anti-viral facemask is quite different from all other masks on this list. Whereas the others are generally intended to be effective against pollution, this mask is intended to be used for viral protection. It currently does not hold any third-party testing certificates.

The mask does, however, feature Polygiene’s ViralOff technology. This technology is capable of killing viral particles over the period of a few hours and makes it possible to rotate between less masks. The only other mask on this list with the same coating is the Conceptar mask, which also features ViralOff.

While this mask does lack in overall testing and pollution protection, it is the cheapest mask on this list. Therefore, it may be a good choice for anyone looking for cheaper protection in areas where masks are essential.

Read more – Aropec anti-viral mask full review

Pros

  • Much more affordable than other masks on this list
  • ViralOff coating for kill viral particles
  • Relatively comfortable

Cons

  • No third-party testing
  • Should not be used for pollution protection
  • Loose fitting and can be hard to adjust

12. Vogmask

Vogmask Review

Vogmask is one of the biggest players in the reusable mask game. They have been around for a long time, and create quality masks that are well-known and of a good quality. 

Vogmask are standard reusable masks. By standard, I mean that they are fitted with straps behind the ear, they have a wire nose-piece, and they are a typical shape. They also have models that feature valves as well as some without.

These reusable masks have over 95% particle filtration. However, please note, these masks DO NOT hold an N95 rating. Their filtration does meet the requirements of the N95 certification, however, they do not officially hold the rating.

Read more – Vogmask full review

Pros

  • Over 95% particle filtration
  • Many different designs
  • Standard fit (if a disposable mask fits you, this should too)
  • Available in many different countries

Cons

  • Ear-straps can cause pain after long periods of wear. A strap is available to remedy this.
  • Wire nose-piece can be a bit taught and hard to adjust properly
  • Many masks on this list have higher filtration ratings

13. MeoAir Mask

MeoAir Pollution Mask

MeoAir is a mask made in New Zealand using a wool filter. This filter is named the Helix filter and is produced by Lanaco.

The mask meets the NZ/Aus P2 standard which means that it provides > 94% filtration. However, the Meo Lite actually offers significantly more, with test results showing a minimum of 96% filtration of fine particles.

Since the mask is made from wool, it also offers best-in-class breathing resistance. When I tested the breathing resistance, I found it to be significantly lower than alternative masks. In test results, it’s as much as 5x lower than masks that offer comparable filtration.

Read more – MeoAir Lite full review

Pros

  • Wool filter makes breathing far easier than comparable masks
  • > 96% filtration at 0.3μm and > 99% at 0.1μm
  • > 99.99% bacterial resistance
  • Comparably cheaper than other options on this list
  • Replaceable filters

Cons

  • Lack of test results for viral particles
  • Masks ship from New Zealand, meaning that waiting times can be long

14. Purely KN95 Mask

Xiaomi KN95 Fan Mask

The Xiaomi Purely KN95 mask is unique as it is the only mask on this list that offers active cooling. That is to say, this mask has a fan and motor that allow it to actively intake air. Not only does this assist in breathing, but it cools the inside of the mask.

Anyone that has worn a mask or respirator for an extended period of time knows that they can become very uncomfortable very quickly. The Xiaomi Purely tries to solve this problem by making sure that air is constantly flowing.

While the fan has limited impact (you can find my full review here), the mask is still rated KN95, has interchangeable filters, and is actually quite comfortable. If you don’t mind the size and extra weight of the fan, this is a good choice of mask.

Read more – Xiaomi Purely KN95 full review

Pros

  • KN95 filtration
  • A comfortable mask that comes with a headband included
  • Interchangeable filters that can easily be replaced
  • Clean, fashionable design

Cons

  • The mask is significantly heavier due to the fan module
  • The fan has limited impact. While it can help at times, it can also be loud at the faster speeds

Which Reusable Mask Is Best?

Breathe Safe Air Bloo Mask Review

As much as I wish that I could give an overall recommendation, it unfortunately isn’t that easy. It depends on the use-case and the person in question. However, I hope that this list has given some indication as to which masks might work best for you.

Also, this list is far from exhaustive. There are a TON of different masks out there, and it’s impossible to list them all. This list only contains masks that I have reviewed, as I don’t want to discuss or suggest masks that I have no experience with. However, I will do my best to keep expanding this list.

Overall, all of these reusable masks can provide protection. However, no matter which mask you purchase I would say that a headband is an essential. You can purchase these headbands from Amazon. Headbands will make whichever mask you choose far more comfortable to wear.

Finally, remember to always follow best mask practices when wearing and using masks. Masks do not guarantee protection.


Reusable Mask FAQ

How Long Do Reusable Masks Last?

This depends on the mask in question, however most are rated for at least 100 hours. Many are rated for much longer, and can be used for up to 300 hours.

Other factors such as air quality can impact how long the mask can be used for.

Can I Wash A Reusable Mask?

Before you wash your mask make sure to check the manual and/or website of the brand. However, most reusable masks can indeed be washed, and many even allow you to replace the filter.

Is a Mask With a Valve Better?

When it comes to fine dust protection, reusable mask with a valve are generally best as they are more comfortable and are less humid inside. However, if you are looking for viral protection then a mask without a valve is best as it filters air both ways.

What Is the Best Alternative to Cambridge Mask?

There are many great alternatives to Cambridge Mask. Vogmask, Airinum, and Respro are all popular reusable masks that perform similarly to Cambridge Mask.

What Is the Best Alternative to Vogmask?

There are many different reusable masks on the market. Cambridge Mask, Airinum and Respro are the biggest competitors to Vogmask. However, there are also many more reusable masks available that provide great filtration such as O2 Canada and Conceptar.

What Are Some Affordable Reusable Masks?

The most affordable masks on the list is the Aropec Reusable Mask. However, this mask does not offer fine dust protection. For fine dust the MeoAir Lite, Conceptar mask and Re-Mask are affordable choices.

What Is the Best Reusable Mask?

Unfortunately there is no clear answer for this. It depends on the situation and use-case. For example, some great choices for sports are the R-PUR Nano Light and Bloo Mask. On the other hand, for daily wear Re-Mask and Conceptar are good choices.

What Are the Best Masks With Replaceable Filters?

While all masks on this list are reusable, only some have replaceable filters. Totobobo, Gill Mask, Conceptar, Re-Mask, Mau Mask, MeoAir and Purely all feature replaceable filters.

13 thoughts on “14 Best Reusable Masks – Cambridge Mask Alternatives”

  1. I have a problem calling half of these masks “reusable’. While Respro, Totobobo, and a couple others definitely are, the Cambridge, Vogmask, and others like it are not as you have to throw the entire mask away when the filter stops working. It may a lot longer than an 8 hour shift but you still toss the whole thing.

    1. Hello Mike,

      I can understand how the wording can seem off, and I appreciate you pointing that out – I will make sure to make that more clear in the article.

      While I do understand your point, I consider all of these masks reusable. The fact that you can use them more than once in my mind means reusable. Of course, they do have to be replaced every (usually) couple of hundred hours, and they are only reusable to a point.

      The other masks that you pointed out (as well as MeoAir, Xiaomi Purely, and a few others) I would usually refer to as interchangeable or replaceable filter masks. Of course, they do also have limits and I’ve had to replace some of these masks before as they get dirty, worn, or damaged otherwise.

  2. Perhaps worth clarifying that several of these have an exhaust valve, so (as your article about valves makes clear) anyone buying because of the pandemic should rule them out as they will not prevent your breath infecting anyone else. The valved masks are Cambridge Mask, Vogmask, Airinum, OnroadCo, Purely and Respro.

    1. Hello, Gareth.

      Thank you for pointing that out. That is a great suggestion!

      I will update the article to reflect the changes you suggested.

  3. I feel like you need to note, in bold, warnings about valved masks during a pandemic. I understand you started these articles because of fine dust and pollution issues in South Korea, but this is a pandemic and many of your reviews still talk about valved masks as a positive thing, which misleads people. Reading your reviews, it is very hard to figure out that they’re actually very bad for the current pandemic and that having a valved mask can harm others with your droplets.

    1. While I understand your point, I do mention at the beginning of the article:

      ‘These masks are generally intended to protect against typical outdoor air pollution. That is to say, they protect against fine particles and VOCs. If you need protection from a specific gas or particle, make sure to do research and to purchase the right mask’.

      As you mentioned, this blog is air pollution based website and I make that as obvious as possible. Although you are right, and that most people are purchasing masks for the virus now, I hardly think that I am misleading people as you say. I even recently wrote an article about valves and when they are bad – https://breathesafeair.com/why-do-masks-have-valves/.

      However, I do understand your point and I can see the confusion this can cause. I have begun to cover valves in more detail in my more recent reviews (since the virus became the primary need for masks), but I still need to go back and update all of my older articles. I will see about adding a banner or insert that goes across all of my posts. I have already added a bold warning on this post.

      Thank you for the feedback!

    2. I wear a valved respirator and a surgical mask over it. That way, I get the heightened protection of a respirator while at the same time stopping large droplets from escaping.

  4. är mask has a valve, but exhaled air is still filtered through the nano filter behind. I have one, but sick and tired of angry looks from people in public places. Just discovered another mask with a silly name called Banale. Filter has a valve but it is hidden behind the silver oxide-covered mask. Mask looks a bit weird, but worth a look…

    1. I understand your issue, I have felt much the same. Masks with valves here are banned, and even though Conceptar has a filtered valve there is a carpet ban on all masks that feature one – regardless of how they are implemented. Before the ban it did also draw some looks due to the valve.

      I just learnt about Banale yesterday from another reader! I will check them out. Thank you!

  5. Ethan
    Thank-you for a super site! Do you think the candle test is a waste of time/irrelevant re valved masks (such as cambridge masks)?

    1. Hello again, Steve!

      Firstly, thank you for your kind words!

      Secondly, I am not an expert on the matter so please note that this is just my opinion. I would generally agree that the candle test isn’t a particularly good method for assessing the filtration of valved masks as these masks are designed to allow for higher air-flow exiting the mask. To my knowledge the candle test is for cloth masks/other low-filtration coverings and as such it shouldn’t be so important for masks that make use of proven filters. I would say that it is usually a waste of time for these masks (regardless of whether or not they have a valve).

  6. You do a great job with your mask picks. I have re-mask and a metamask and I feel that meta is a better choice.

    I work in a deli and recently 3 out of 4 of us tested positive for covid. They were wearing re-mask and I was wearing a metamask, they for sick and I was fine.

    1. Thank you, Christopher.

      I am sorry to hear about your coworkers, I hope they recover well and that you stay safe!

      It’s interesting to hear about the masks. I wonder if that was due to the masks or other factors (as the virus can spread many ways).
