AR Face Mask (ConceptAR) Review

AR Face Mask (also called Concept är or Conceptar) is a Czech company that has recently started making masks. When I recently found their website I found their design quite unique among cloth face masks and I wanted to see exactly how their new approach worked.

There are a few key differences in the AR Face Mask, but the two that most interested me were the use of velcro to attach the mask to the filter and the inclusion of a valve – a valve that is implemented in such a way that it still filters air both ways. 

Another very interesting addition that I would be remiss not to mention is the addition of Polygiene’s ViralOff technology. This technology kills viruses on surfaces over a couple of hours and I have only ever seen it implemented in one other mask before

All of these additions made me quite intrigued by the AR Face Mask. I reached out to the company to ask if I might be able to get a review sample and they were happy to provide. Thanks to them I am able to bring you my full AR Face Mask review today. 

In this review, I will cover all aspects of the mask, from filtration to design, cost, style and more. If you didn’t understand anything that I mentioned in the introduction, don’t worry! I will cover it all in more detail in this article.

I reviewed the AR Face Mask WITH a valve. However, a valve-less version is also available. This version is similar in every way except that it lacks a valve. Therefore, this review largely applies to both versions of the mask.

Conceptar Filter

The most important factor of any mask is, of course, the filtration. Although there are many masks out there, relatively few of them are capable of filtering out small particles. Typically, there are three main types of particle testing: latex (standard fine particles such as air pollution), bacterial and viral. 

Filtration testing is usually carried out at around 0.3μm (0.3 micrometres = 300 nanometers) as this is often the MPPS or most penetrating particle size. Something that many people get confused about is how exactly filtration works. I often get questions regarding the filtration of smaller particles since testing is carried out at larger sizes. 

However, 0.3μm is actually a more penetrating particle size than smaller particles (until a certain point). Therefore, while not tested specifically at smaller particle sizes, 0.3μm is a ‘worst case’ scenario. I won’t discuss the MPPS in more detail in this article, but I recommend learning more about the MPPS if you want to know exactly how mask filtration works. 

I mention this because I very often get questions about mask filters and whether they can filter smaller particles. The truth is that yes, provided the mask is fitted and used correctly they very often can filter smaller particles. 

Back to the AR Face Mask filtration then. Currently, the masks do not have latex particle testing (which represents a typical fine particle) but they do have BFE and VFE (bacterial & viral filtering efficiency) test results. Both of these tests were conducted by Nelson Labs.

With five samples tested, the AR Face Mask filter was able to filter out ≥ 99.7% of viral particles. This was the worst result posted, and the two other samples were capable of ≥ 99.8% filtration and the final two were capable of ≥ 99.9%. 

With five more samples tested, the AR Face Mask filter was capable of filtering ≥ 99.8% of bacterial particles. This was again the lowest result posted, and the other 4 samples achieved 99.9% filtration or greater. 

These filtration results make the AR Face Mask filter comparable to other high-filtration masks. For reference, the Cambridge Mask features ≥ 99.3% VFE and ≥ 99.6% BFE. Vogmask features 99.9% in both.

The lack of latex (PFE) testing is a downside and I hope that they will provide test results on that in the future. However, the BFE and VFE test results both show high results. It is important to remember though, that these results only apply to the filter and not the mask itself.

This leads to an issue, however. I found that the filter in the AR Face Mask was very loose and it could easily move. While I will discuss the loose filter in more detail later in this article, it’s important to note here too. the filter moves a lot, and it’s not connected to the mask properly. This means that unfiltered air can possible pass through.

This is obviously a big issue, and while I can’t test the severity of the problem, it’s not confidence-inspiring. I suspect that at least some air bypasses the filter completely. Therefore, while this mask likely provides better filtration and protection than lower-filtration devices such as surgical masks, I would trust masks with built-in filters or well-fitting replaceable filters more.

For these results to be applicable, the mask must be worn properly and fitted correctly. It is important to follow the manufacturer’s guidelines to make sure that the mask is used as intended for the best protection.

Polygiene ViralOff

Image from Polygiene.

Information in this section is taken from the ViralOff ISO-test page. ViralOff is a coating that can be applied to many different fabrics that will greatly decrease the number of viral particles on a surface over time. AR Face Mask feature ViralOff technology.

ViralOff does not work instantly, and it is still vital to make sure that you still follow hygiene standards and treat your mask as per the WHO guidelines. Where ViralOff does shine, though, is over a period of a few hours.

Over two hours ViralOff has been shown to kill around 99% of viral particles. This number increases as more time passes. Currently the technology has been tested on Influenza A, BirdFlu, Norovirus, and Corona (SARS) viruses (Polygiene).

Where this technology shines is in the re-use of masks. Since viruses can live on some surfaces for weeks, it’s important to disinfect masks and clean them properly between uses. However, ViralOff can remove some of this need, as the masks are capable of removing viruses themselves over time.

This means that rather than waiting between long periods between mask uses (or cleaning after every use), you should be able to use the leave the mask sitting over night before using it the next day. Since most people don’t have enough masks to constantly wash and rotate their usage, this addition is very welcome.


The AR Face Mask doesn’t particularly stand out from other popular cloth masks at first glance. Rather, it looks quite similar to many ‘standard’ looking masks such as Cambridge Mask and Vogmask. However, once you look deeper there are actually a few interesting aspects of this mask. 

There are two distinct parts to the AR Face Mask. The outer shell (which I refer to as the ‘mask’) and the filter. Where some masks feature built-in filters that can’t be replaced, the AR Face Mask allows the user to change filters when needed. The filter and the mask attach with velcro straps that are placed on the interior of the mask.

The mask shell features Eco Acqua Zero technology. This technology uses a special fabric that is not only water repellent but also assists with water removal from the mask. This is especially important because filters quickly lose their filtration efficacy when wet. 

Although the Eco Acqua Zero technology will not protect the filter in strong rain, it does provide some level of water repellency in low moisture environments. This is a welcome addition to the mask and it really provides no downside. 

As previously mentioned, this fabric is also coated in Viral Off technology. On the right-hand side of the mask (between the right cheek and chin) there is a valve. However, this valve isn’t a typical unfiltered exhalation valve as the filter covers the valve when worn. 

Conceptar ViralOff Mask

This means that exhaled air will still be filtered, but at the same time, the wearer also gets many of the benefits of a valve (albeit to a lower extent). Valves are usually used to decrease breathing resistance and to keep temperatures and humidity lower within the mask. 

Moving towards the back of the mask you will find the ear straps. As anyone familiar with this blog will know, I am not a fan of ear-strap based designs. This is due to the fact that they often place a lot of pressure on the wearer’s ears and they can become very uncomfortable over time. 

In saying that, I have worn the AR Face Mask for over 4 hours on a few days this week and I have noticed little pain. I believe this is due to the fact that the straps are quite thick and flat, making them distribute the pressure more evenly. 

The straps also feature a small buckle for adjustments. I am not sure if this buckle is better than a sliding clip design (as seen on the Bloo Mask), but the function is similar. In the end, it makes the straps adjustable and therefore the size – this is never a bad thing. 

Conceptar Mask Inside

The mask itself doesn’t feature a wire nosepiece. Rather, this is built into the filter. I found this to be a very interesting design choice, and it’s something that I have quickly come to like. I have been able to adjust the filter more precisely as the mask and filter can be adjusted somewhat separately. 

Finally, there is one big downside that I have noticed with the design of the AR Face Mask. Since the filter only attaches at the top and the sides I very commonly find myself breathing the filter in. Although I am not very bothered by this, since I am used to wearing such masks, I can see it being very annoying for others. 

On top of this, I can’t recommend this mask for sports or exercise due to this. It will interfere a lot with the breathing of the wearer. However, although I have no experience in making masks myself, I think that this could be remedied quite easily by adding one or two more velcro pads to the filter.

Rather than just having one at the top of the nose, I think that adding one in the middle and bottom could also help. This would also go a long way towards increasing the filtration performance as mentioned in the previous section of this article.

Concept AR Pollution Mask

Fit is vital when it comes to masks, as an incorrectly fitting mask provides little (if any) protection to the wearer. While these masks are designed for general consumer-use, it’s still important to make sure they are fitted correctly. 

For this reason, it’s important to follow the manufacturers guidelines to make sure that you use the mask properly. On top of this, make sure to perform a fit test once you have donned the mask. 

The fit with the AR Face Mask is one of the better fits that I have experienced in a cloth mask. While there are definitely masks that fit better (such as the silicone Gill Mask and the much sturdier R-Pur Nano Light), these are all much bigger masks. 

Compared to other similar masks though, the AR Face Mask has provided a good fit for me. Although this experience may differ for others, there is a wide range of sizes available and it should be possible to find a good fit for most adults. 

The good fit comes from two main factors. Firstly, the adjustable straps. Since the tightness of the straps is easily adjustable it’s easy to make sure that it is adequately tight and that it won’t move too easily. 

Secondly, the separation of the filter from the mask means that it can be fitted more precisely. This is my first time experiencing such a design in a cloth mask, and I hope that more masks implement this in the future. 

It was very easy to adjust the wire nosepiece and to make sure that it was not leaking. Although, as I did previously mention there are some issues with the filter being pulled in when I breathe. I hope that this is something that will be improved upon in the future.

The fact that the filter can easily move also leads to some questions about the performance of the device. While I found the mask itself to fit well, this can only provide limited protection if the filter itself isn’t fitted correctly (which seems to be impossible) and has leaks.

Overall, the fit of the AR Face Mask is one of the better fits that I have experienced in a cloth mask. One of the biggest issues with cloth masks is their (often) loose fitting, but this mask is both easy to fit and easy to identify leaks on.

Concept AR Mask Exterior

As someone who is not a fan of masks that stand out, I really liked the design of the AR Face Mask Logo Mask. Although the company does also offer a basic black mask with no logo, I actually think that the logo adds some flair. 

The logo can be found in many different colours – from neon pink to grey. The logo sits on the opposite side to the valve, meaning that it can be found on the left cheek of the mask.

Other than the logo and valve the front panel of the mask is totally bare. Currently, all of the mask models use black as the background colour, and I think that this is an area that can be expanded upon in the future. 

However, in the meantime, I think that AR Face Mask has created a design that has a good balance of flashy and subtle. The use of black also means that this mask can fit with a large variety of outfits and that you should have no troubles matching it with other clothes!

Lifespan & Cost

Conceptar Mask

The AR Face Mask and replacement filters are comparatively priced to other similar masks on the market (such as the MeoAir Lite). The initial mask (with one included filter) costs $30. The filters come in packs of 3/6/12 ($12/$24/$48 respectively).

The good news is that the lifespan of the mask (not the filter) is indefinite. As long as the mask is stored in a dry, clean location and is only washed when needed, the mask should have a long lifespan.

I was curious about the lifespan of the ViralOff treatment on the mask and I contacted AR Face Mask with this question. They said that if the mask is only washed occasionally, the treatment should last years. However, it will lose effectiveness after each wash. I have no data regarding the treatment lifespan, but this is what I was told. 

The replaceable filters should be changed out much more regularly. The lifespan of the filters is highly dependent on many different factors such as the pollution level (measured with the Air Quality Index), humidity, daily usage and more. 

However, AR Face Mask generally recommends 2 weeks of usage in a less polluted environment. If you are living in an area with significant air pollution levels, then more regular changes will be required. If the filter begins to become significantly more difficult to breathe though it should be replaced.

If a filter lasts around 2 weeks you are looking at $8 per month for replacements. In the long term this will come out far cheaper than using disposable masks. Just make sure that you take care of the mask so that it doesn’t need replacing!

Conceptar Pollution Mask review

After using the AR Face Mask as my daily mask for over a week now, I’ve found the mask to be a good replacement to surgical masks and other lower-protection devices. My biggest issue with the device is the loosely-fitted filter, and this is why I hesitate to recommend it for riskier situations where a better fitting mask is essential.

To minimise this issue, I would like to see an extra velcro strap added to the filter and mask to prevent the wearer from breathing in the filter. I also think that it would be nice to see some PFE filtration results for the mask to add to the BFE and VFE results.

With the loosely fitting filter and the lack of PFE filtration results, I see this mask as an upgrade to a surgical mask but below better-sealing masks and respirators in regards to protection. For that reason, I would not recommend it as an air pollution protection device.

With that being said, there are also many aspects of the mask that I have come to like. The addition of a valve that still filters exhaled air is interesting and something that is quite unusual on a mask. While this does decrease the valve effectiveness to some degree, it does still lower breathing resistance compared to having no valve. 

The velcro design that allows the filter to attach to the mask is a fantastic addition. I wish that such features could be found in more masks, as it is often hard to fit filters correctly. Especially on cloth masks. I also found the use of a nose piece in the filter rather than the mask a good addition. 

If you are looking to upgrade your daily mask from a cloth or surgical mask, the AR Face Mask is worth considering. It’s a subtle-looking mask that works well with many outfits. It provides good bacterial and viral filtration, and the addition of ViralOff technology is something that I have only seen in one other mask.

If you are looking for a sports mask, however, I am hesitant to recommend the AR Face Mask due to the filter being quite loose and often getting in the way of breathing. If you’re looking for a mask for air pollution protection, I would recommend checking out other reusable masks.

  1. Hi, great and useful site, especially in times like this, but I believe you made little mistake. As far as I can see they are Czech and not French company …

    1. Hello Tomi,

      I believe you are right! I got them confused with another company that I was writing about. Thank you for pointing that out, I will update it right away.

  2. Thanks for the review. Good to know that more companies are focused on coming out with quality masks.

    Btw, Polygiene ViralOff is also used in Airinum 2.0 and the upcoming Banale Silver Mask 2 (which I have backed on Kickstarter a few days ago). Velcro is also used to attach the filter to these 2 masks.

    The nose piece and foam on filters can be found in both AusAir and Airinum masks.

    Perhaps you can do a review on these next?

    1. Hello Philip,

      Thank you for letting me know of these masks! I have always heard a lot about Airinum, but since I started this blog they have been in very limited supply and I haven’t had a chance to get my hands on one of their masks yet. I had no idea that they use ViralOff also though, so thank you for letting me know!

      I am hoping that I can get the chance to test the masks you mentioned soon, I am happy to hear that a similar design is also being used in other masks as it seems like a great choice. I have an AusAir mask on the way, but I think it is still a few months away from being shipped.

      Thank you for sharing your knowledge! That is very interesting to hear. I will do my best to review those masks in the near future.

  3. Also, I have been doing some research on this particular product called SDST which has been proven to deactivate viruses, bacteria and fungi upon contact.

    It became famous in Singapore when the Housing Development Board purchased and applied SDST in all HDB flats lifts buttons. It is a self disinfecting coating that can last for 90 days. Singapore Changi Airport and many other places like gyms also started to use this treatment.

    I have asked them via Facebook ( whether it can be applied to textile fabrics. Apparently, it can and the coating will remain even after washing with soap + water. It is safe for inhalation and non toxic.

    I suppose this can be a good substitute for Polygiene ViralOff as I used it on my other masks like o2 Canada Curve and Breathe99 B2 Mask.

    1. This is very interesting and something that I will definitely look into further! If it can be easily applied by the user it sounds extremely useful. Thank you again for the information 🙂

  4. Hello, Ethan, and thank you for all this useful information posted here!

    As someone familiar with this type of mask, you are no doubt aware of common imperfections like poor fit and leakage. The mask reviewed above, however, would seem to offer more favourable sealing characteristics—in comparison to some similar masks. Nonetheless, judging by the available photos and videos, the design still looks like one prone to inward leakage; I am not entirely convinced by the nosepiece with its strip of foam, although the feature can undoubtedly help in creating a tighter seal. Respirators, including some masks also reviewed here, are actually designed to prevent leakage by providing an airtight seal. How tight a seal does är manage compared to them?

    The critical feature would seem to be the fit around the nose; i.e. the material needs to be pliable enough for a close fit, and there needs to be a sufficient pull towards the face. Most masks handle this inadequately, as the pull on the nosepiece is rarely strong enough, and typically, there’s a visible gap around the nose. How does är perform in these respects?

    1. Hello Oula,

      As you’ve mentioned many masks feature such imperfections and have some level of leakage – especially when it comes to cloth masks. I am only comparing Conceptar to other cloth masks, as the seal and leakage can’t compare to respirators or silicon/plastic masks (which perform much better).

      From my experience there is definitely some leakage and I would not use it as a pollution mask (it also lacks PFE filtration testing). It definitely does have inward leakage, however, as do all cloth masks. I do think that it performs better than some other cloth masks that I have tested though as I was able to achieve a better seal with this. Like you’ve mentioned, the nose area is often the biggest issue when it comes to a seal. I actually found the nose seal better on this mask than with other cloth masks. However, the seal around the chin concerns me as the filter can easily move and this is why I believe a connection between the mask and filter needs to be added at the bottom.

      I hope this helps! If you are looking for a mask/respirator with a stronger seal I would recommend checking out Gill Mask or O2 Canada, both of which I have reviewed here 🙂

  5. Has anyone thought about double-sided adhesive tape on the filters to make them stick better to the mask? I’m ordering some and I will let you know the outcome.

  6. This mask fits poorly and the very thin filter collapses against your nose as you inhale. The company doesn’t post any critical reviews on its site.

    1. Thank you for the comment. Very helpful, since it’s not cheap to begin with. I am glad that I ran into your review before buying.

  7. Thank you for the great review! I bought a mask a few weeks ago and I am very satisfied. is very light and comfortable to wear. After 6 hours of train travel, I completely forgot that I still wear it. Also appreciate the self-cleaning function.

  8. It’s important to know that this is a sight-unseen, hope it fits purchase. That’s understandable from the hygiene viewpoint, yet what happens when the mask doesn’t fit for reason beyond the customer’s control? In short, AR’s policy is you bought it; opened it; so you own it regardless…for any reason. In our case, per AR’s product description, we had a “borderline” face size. So, we followed AR’s recommendation to move up a size and use the straps to adjust. The “move-up” in size made the mask loose and droop under the chin. When the straps were pulled to tighten the the mask to the face, it would not tighten, as the flat straps shown on their site arrive sewn and welded to more of a cord shape. Simply, the cord shape would not slide through the flat snap. We contacted customer service and explained the situation and the differences from what was shown and what was received with pictures attached. The response we received, was “We are truly sorry for the inconvenience”; no returns once the package was unsealed; BUT here’s a 30% off code towards your next purchase. We purchased two (2) of these masks with extra filters ($80 US). We only had an issue with one of the masks, so they had a satisfied customer for half of the purchase. Unfortunately, that left the other half unsatisfied. The only thing left to do was file a dispute with our payment processor and after submitting the same explanation and pictures we did to AR, the payment processor ruled in our favor. We did not receive what was advertised. Now AR have an unhappy customer and this review to hang their mask upon. I’ve been in the customer service industry for 40 years and learned two very important lessons along the way. 1) The customer is always right; and 2) the cost of a dissatisfied customer is many times over more costly than what a replacement and a happy to help you response would have cost.

  9. Looked to be a good product but unfortunately I haven’t received it even after a week of placing my order and after specifically paying for DHL Express (plane) shipping. I can no longer use it for my travel plans hence have asked to cancel my order. You dont get happy customers if you cant fulfill your orders in time.
