Re-Mask Review, Anti-Pollution & Viral Masks

Re-Mask Pro Design

Re-Mask is a recent entry into the reusable mask market. This company, based in Hong Kong, has created a variety of different reusable mask products that are designed to do everything from protecting the wearer from small particles to replacing the filters in their current masks. 

The company currently has four masks available. The Re-Mask Casual (with ICY & Organic models), the Re-Mask Pro and the Re-Mask Sports. However, I have already done a Re-Mask Sports review in a separate article. The company also makes Earth Filter, a filter that is designed to fit inside a wide variety of other masks in order to reduce costs and waste.

Re-Mask masks are primarily designed to protect the wearer from particulate matter, viral, and bacterial particles. Depending on the model that you purchase, you can find models that offer valves as well as non-valve variants

Re-Mask offers a solid line up of masks and filters with different intended uses and audiences. In this Re-Mask review, I will look into the facts behind these masks as well as my experiences. I will also compare the different models and discuss the differences between them.

Re-Mask Models

Re Mask Organic

There are three different models of Re-Mask that are available. All of these masks use the same filtration technology (which I will discuss in more detail soon), but they all have small differences. When deciding which Re-Mask model to purchase, there are two main questions to ask:

Do you need a valve? If you are looking for a mask for spreadable particles (such as viruses) then you do NOT want a valve mask. Some countries have even recently banned masks with valves. However, a valve can be useful for fine-dust protection when only the wearer needs to be protected. 

Do you want a mask with replaceable filters? Some Re-Mask models allow the user to change the filter when needed. This means that the mask will have more longevity and that it doesn’t need to be replaced as regularly. However, it also means that the user will need to change the filters and make sure that they are fitted correctly. 

Re Mask Models

Depending on your answer to these two questions you can pick either the Re-Mask Casual or the Re-mask Pro. The Casual mask features a valve-less design but has replaceable filters. On the other hand, the Pro model has a built-in filter that can’t be replaced but also features a valve.

For the majority of people, Re-Mask Casual is a better choice. If you are looking for a mask for the pandemic, the Casual is the only choice.

The ICY variant of the Re-Mask is the same as the Casual Mask except that it features a material that should make the mask cooler to wear. However, I have not tried this mask and I can not confirm whether this addition is worth it or not.

However, if you are looking for a pollution mask or mask for allergies that are more breathable, then the Pro model is a better choice. This is especially true if you believe you will be wearing the mask while exercising or during physical exertion.

Re Mask With Earth Filter

As mentioned above, the Re-Mask Pro uses a built-in filter whereas the Re-Mask Casual uses an additional filter that can be changed. This means that the Casual mask will inherit the filtering properties of the filter that you use, assuming that it is fitted correctly.

Re-Mask currently offers filters from their own site for the Casual mask and it also makes another product named the Earth Filter. Both of these filters, as well as the Pro Mask, share the same technology and filtration characteristics. The filtration specifications discussed here are for the Pro, Re-Mask filters and Earth Filter.

Re Mask Filter

The filters have been tested by the third party laboratory Nelson Labs. They have had particle, viral and bacterial filtration testing at 0.3μm (the MPPS or most penetrating particle size). The test results are shown on the table below.

Re-Mask FiltrationParticleViralBacterial
Filtration %≥ 99.76%> 99.9%≥ 97.3%

All data used is from the Re-Mask Nelson Lab test results.

These filtration results put the Re-Mask among the best reusable masks in regards to filtration efficacy. Many masks, such as Vogmask, filter to lower performance levels and are rated to filter only > 95% of particles at the MPPS.

A carbon filter is also included within all of the aforementioned filters. Carbon filters are designed to filter some organic compounds (such as VOCs) and are also effective at removing odours. However, they will not work against the majority of non-organic chemicals.

This is a welcome addition to the mask as it means that not only will the wearer smell fewer smells, but it can also keep the mask smelling fresher for longer. Some masks such as Cambridge Mask offer carbon filters, but it is not standard for most brands.

Overall, the Re-Mask masks offer some of the better filtration available among reusable masks. They are capable of filtering well over 99% of latex particles (standard test particles), over 99.9% of viral particles and over 97% of bacterial particles.


Re Mask

It is also important to note that mask & respirator fitting is vital. For the best protection, professional fit testing is required. However, for the vast majority of people that training isn’t accessible. Although filters are often rated to filter > 99% of particles, this only applies if air is actually required to pass through the filter. 

While there is no substitute for professional fit testing, there are many guides out there that can allow users to learn how to self-fit test to ensure that their masks are worn correctly. For respirators, this guide from the CCOHS is a good start.

I found Re-Mask masks to be quite loose fitting out of the box. I believe this to be due to the materials used. Re-Masks are very lightweight and they are very light on the wearers face. However, I found that this meant that they were harder to fit than other masks such as MeoAir and Cambridge Mask

After adjusting the mask and tightening the ear-straps (or by changing the ear-straps into head-straps), I was able to achieve a suitable fit. After performing a fit-test, I found minimal leaks around the edges of the mask. However, this process did take longer than with most other cloth masks. 

Re Mask Design

Something that is important to note is that Re-Mask sizes are larger than other masks. That is to say, a small Re-Mask is significantly bigger than most other small size masks. The same goes for comparing large Re-Mask to the large size of most other brands. For this reason, make sure to check their sizing guide. You may need to purchase a size smaller than you normally would. 

The masks are very lightweight and they are lighter than most other comparable masks on the market. While this does make them harder to fit, it also means that they can be more comfortable to wear for longer periods of time. Being made from lighter materials, the masks are also cooler.

I found this very noticeable in the past week when I have been wearing a Re-mask Organic (without a valve). It is currently summer in South Korea, and the air pollution in Seoul often means that wearing a mask is advisable. However, the temperature also often gets to 35 degrees. 

I found Re-Mask to be more comfortable in this hot weather. While realistically no mask is comfortable in hot weather, compared to other masks that I have experienced I found this to be on the more comfortable side.

Re Mask Organic ICY

As I have already mentioned, the first two aspects to stick out to me in regards to design were the size and materials. The masks are quite large, so it may be necessary to purchase a smaller size than you normally would. 

The materials also feel very light and thin. This does not imply anything about the filter – there are many factors that influence filtration efficiency other than thickness. However, this was quite surprising to me after experiencing many other masks that are often thicker and heavier. 

Re Mask Casual

The mask follows a relatively standard cloth design. There is a wire nose-piece at the top of the mask that allows the wearer to mould the mask around their nose in order to minimise leakage. The wire is soft and easily malleable. 

All Re-Mask models use a ear-strap design. This is not something that I am fond of as I prefer the more sturdy fit of a head-band. Luckily, this is something that is quite easy to fix. You can either use a head-strap accessory such as this one, or simple create a head-strap using your own materials. 

Across all of their mask types, Re-Mask also offers many different designs. You can find everything from solid-colour masks to masks with dinosaurs on them! There is a lot of variety. The masks may not be as fashionable as masks made with fashion as a primary goal (such as the fashionable Mau Mask’s and Idontcare masks), but there are a lot of choices to suit everyone.


Re Mask Pro Hong Kong

Although being a relatively new entry into the market, Re-Mask has already created some quality products that have been tested by one of the most trusted third-party labs. They have also brought some innovation to the field – especially with their Earth Filter

The masks are comfortable and have had their filtration efficiency tested. The filters are easily replaceable (on the Casual model), and the masks are lightweight making them easy to wear for longer periods. 

The only downside that I really experienced with the masks was with the initial fitting. It was quite hard for me to adjust the masks so that they fit correctly without having leaks around the seal. After adding an elastic string to create a headband and tightening the mask though, I was able to get a good fit. 

I will keep updating this article with my future experiences of the products. At this point I have used the masks for around a week, and if anything changes regarding my experiences this article will be updated to reflect that. 

If you want to learn more about reusable masks you can find another article that I wrote about here. I discuss some of the most popular reusable devices on the market as well as their upsides and downsides.

  1. I’ve ordered 8 masks using your link (thank you for the discount :)). It took one month for the package to arrive. Customer service was totally unresponsive when I was inquiring about the shipping. The package arrived today finally and there were 2 masks in it instead of the 8 I have ordered and paid for. Customer service is still unresponsive. The only option left is a chargeback. I’ve spent a whole month waiting for the masks, and now I have to buy 6 masks from elsewhere and I still don’t know if I’ll get my money back 🙁
    I think people should know this because they make the same mistake and order from them…

    1. Hello,

      I am very sorry to hear about your experience. That is terrible.

      I am going to contact them in regards to this matter and see what they say. You definitely deserve to be kept updated on the matter if nothing else.

      I am also wondering if this is a one-off or not. Although, if it is a one-off the customer service should still respond and fix the issue.

      I will contact the company and mention your case and see what they have to say.

      Again, I am sorry that this happened to you. Thank you for letting me know.

      1. Re-mask has contacted me since, and they’ve promised to send me the missing items.
        This is a step in the right direction, but I still think it is unacceptable that they were unresponsive before, as they advertise their 24/7 customer service.
        I will keep you updated.

        1. Thank you for keeping us updated. I am glad the issue appears to be solved now, but I agree that the customer service definitely needs to be improved.

          1. Hi there,
            I am experiencing a similar one: ordered a set of masks in october (jst before 2nd confinment here in France) using your code. This is where the tracking stops:
            2020-11-26 14:33 HK, Handed over to carrier / Left for destination
            I ordered another item from HK that was shipped a couple of days later and arrived before Xmas.
            Got in touch with Re-Mask a couple of weeks ago, and they were very responsive but it looks as the new shipment is following the same path:
            2021-01-16 15:19 HK, Handed over to carrier / Left for destination
            I think I will order a set of masks made in the EU, as this is a 50€ painful experience!
            Just to be clear, my comment is made to raise awareness about this brand rather than criticize your website, which I find extremely useful and well made.
            Thank you for doing what you do.

  2. I’m not really clear on how oten the filters need to be changed? They say it’s good for 90 hours, but need to be changed weekly? The pro on the other hand only once every 3 months? That makes the casual much more expensive than the pro. 4 pack of filters is $12, so you would essentially need $36 worth of filters for 3 months in addition to the mask (vs the pro which has the filter)?

    1. Hello Ivan,

      Where did you hear 90 hours? On their website they mention that filters should be changed weekly under ‘urban’ air conditions. From that I would guess the filter lifespan is around 60 hours each.

      The three month estimation on the pro is an estimation also. If you consider an AQI that is relatively standard (let’s say 75) the lifespan is around 250-300 hours for the Pro. It’s confusing how everything is mentioned in weeks/months rather than hours.

      Looking at it that way (in hours) 4/5 casual filters would equal the lifespan of the Pro. However, purchasing 4/5 filters is far cheaper than buying the whole mask again. This is how it becomes cheaper in the long run.

      1. They mention it will last 90 hrs under product description for filterpack. I am confused though… hours are counted when the mask is worn only? Or regardless, once you open the pack regardless of whether you are wearing it or not. I am really only wearing a mask 2-3 hrs a day max.

        1. Ah, I see. That is rather confusing. Yes, hours are generally only counted when worn. However, the lifespan can decrease based on environmental factors as well as how the mask is handled. If you are only wearing the mask for 3 hours per day (or less) the filter should last one month with no issues. However, if the AQI is high (if you are wearing the mask for pollution) then you may need to change it more often.

          1. Yet they say to change filter every week. That to me sounds like you would be wearing it all day (12 hrs) if you needed to do that.

          2. I believe the once per week is a general recommendation. Considering the lifespan is in hours, you could seemingly use it for much longer if you only use it for a few hours per day.

            There is also a big difference in how long you should use a filter for when it comes to pollution or viruses. For pollution, filters can typically be used for much longer than with viruses as with viruses ideally you would want to change your filter after every use (or at least much more regularly).

      2. They mention it will last 90 hrs under product description for filterpack. I am confused though… hours are counted when the mask is worn only? Or regardless, once you open the pack, whether you are wearing it or not. I am really only wearing a mask 2-3 hrs a day max.
