4 Layer Reusable Bamboo Face Mask with PM 2.5 Filters (and Valve Optional)


Washable 4 layer reusable bamboo face mask with filter for adults, non-medical grade and not intended for clinical use. The masks are developed in accordance to World Health Organisation guidelines and AFNOR specifications. Masks are unisex, designed to fit both male and female with extra snug fit and adjustable ties and nose bridge. The masks are made from a mix of bamboo and RPET fabric (inner and outer layer) and double filtration media (bamboo and tencel), a better and more environmentally-friendly alternative to traditional cotton face masks. Our unique fabrication ensures masks are 100% hypoallergenic, antibacterial, water resistant, very breathable and with strong thermal properties (masks keep you cool and comfortable). Each reusable bamboo face mask comes with 2 PM 2.5 filters which can be inserted within the mask in the pocket layer, offering another 5 layers of protection, recommended for high-risk environments. For normal and low-risk environments, our 4 layer technology would suffice to offer appropriate protection.  Filters are not washable and should be replaced with every full 24h of use.

The masks are made from a mix of bamboo and RPET fabric (inner and outer layer) and double filtration media (bamboo and tencel), a better and more environmentally-friendly alternative to traditional cotton face masks. Our unique design and technology ensures the masks are very breathable, water and splash resistant, hypoallergenic and antibacterial, inhibiting the growth of bacteria and minimising the risk of irritation on sensitive skin with prolonged wear. Our bamboo is specifically designed to have high thermal properties which means the masks will keep you cool and comfortable. The valve increases the breathability factor and reduces condensation that would form from breathing. 

4 Layer Unique Protection - Sensitive Skin Friendly

Uniquely developed blend of bamboo, RPET and tencel. A very breathable reusable mask with a water-resistant outer layer, a double filter and a water resistant inner layer. 100% chemical-free, antibacterial and hypoallergenic fabrication.

- high breathability factor and O2 intake 96-99 with mask on
- no fromaldehyde nor decomposable carcinogenic arylamine dye detectable
- latex and nickel free
- pH 6.7 and odourless fabrication
- overall fastness (washing, rubbing, light, saliva, perspiration) 4-5
- valve (optional) is situated inside the pocket (under the inner water-absorbent layer) and has an extra inner filter to ensure all air exhaled is still filtered. Valve helps reduce condensation

High Thermal Properties

Our reusable face masks are designed to have high thermal qualities, meaning they'll keep you cool and comfortable.

Extra Protection with Filter

Each mask comes with 2 PM 2.5 filters (carbon-activated) which offer an extra 5 layers of protection if in a harsher environment. These filters are not washable and should be replaced every 2 weeks or sooner if used for longer periods of time at once (16-24 hours).

Our unique 4 Layer fabrication ensures the masks are efficient on their own and we recommend the PM 2.5 filters to be used when in a high-risk environment. 

The filters come in a separate package and can easily be inserted into the mask when needed, fitting snugly yet comfortably inside the special pocket.

Ethically Sourced and Produced

Reusable face masks produced in our own green studio in London, UK following strict ethical and sustainable standards.

All masks are sustainably  made to order in true slow fashion style to avoid resource waste. The environmental contribution with the purchase of a single mask (approximate):
- 800 liters of water saved
- 0.7 kg of CO2 reduced
- 2.8 Kwh saved
- 1.2 2L post-consumer PET bottles recycled

Best practice while wearing this (or any mask) according to European guidelines:

- Store in an air-tight bag/container
- Do not share masks
- Masks should not be worn for longer than 4 hours at a time; alternate masks if longer wear is required

- Wash hands with soap and warm water before touching the mask

- Make sure the mask fits tightly around your face, do not leave any gaps. Tighten the ties and adjust nose bridge
- Avoid touching your face even if you are wearing a mask and try not to fiddle with the mask once it's on

From all of us at ADKN, please stay safe and make sure all your loved ones are healthy and safe. Together we can make it through!
