Bacterial Filtration Efficiency (BFE)
Our filter media has been tested in compliance with ASTM F2101-19 and EN 14683:2019, Annex B. The filter media received a bacterial filtration efficiency greater than 99.80%.
Viral Filtration Efficiency (VFE)
Our filter media has been tested in compliance with US FDA good manufacturing practice (GMP) regulations 21 CFR Parts 210, 211 and 820. The filter media received a viral filtration efficiency of 99.99%.
Copper Infused Anti-microbial Fabric
We have received additional test results for the copper-infused antimicrobial material which we use to make the carry bag. We sent this material for independent testing to ensure it meets a high standard of antimicrobial performance. STS is a leading independent testing agency and is accredited ISO17020:2012, the highest qualification level of inspection bodies.

Avoid storing the mask in humid areas or in direct sunlight. Each mask pack purchase comes with a carry bag, we recommend keeping the mask in the bag when not in use.
The outer skin can be washed like an item of clothing. Machine wash using cold soapy water. The valves are made from aluminium and silicone, we recommend rinsing these by hand. We do not recommend washing the filters as this will affect filtration performance, rendering them ineffective.
Yes, you can hand or machine wash the carry bag.
How long the filter lasts for depends largely two factors:
The outer skin can be washed like an item of clothing. Machine wash using cold soapy water.
We do not recommend washing the filters as this will affect filtration performance, rendering them ineffective.

Early in the design phase, we received feedback to ensure that our masks were able to be worn with glasses. The reason why glasses tend to fog is because hot air is escaping toward the the nose area of the mask, which means the mask is is not fitting to your facial contours. We have a firm but flexible nose wire built into the filter to ensure that it is able to fit a wide range of facial contours. This prevents hot air from escaping and fogging up your glasses. We have also sourced special nose foam from Japan which aids in creating a firm seal on the bridge of the nose, preventing outward air leakage which can fog up glasses. Finally, our dual valve design allows for greater volumes of air to be released from the valves, and not near the top of the mask which causes glasses to fog.
The handling of the filters and skins, as well as during the assembly phase may involve latex. We also cannot guarantee that our masks will have no elements which contain latex. Those who have an allergic reaction to latex are advised to not purchase this product. We are sorry about this.
Yes! Our stainless steel valves are designed to provide a high level of breathability to the user. Our masks also come with an extra silicone component providing the option to block the exhalation function of the two stainless steel valves. If you are feeling unwell, we recommend blocking the exhalation valves in public spaces. This is a first and is not offered by any other mask with exhalation valves.
No, our filters are custom designed to only be compatible with our mask and cannot be used with other masks.
Yes, very! The magic fit ear loops have been designed to provide enough tension for a firm fit without straining the user’s ears, so that the mask can be used for long periods of time.
Yes! We have a firm but flexible broad span nose wire built into the filter to ensure that it is able to fit a wide range of facial contours. This reduces both inward and outward air leakage. The inside of the filter is cushioned with memory nose foam, to ensure comfort and an effective seal.
