The key to protection is in the mask’s filter. When you breathe with the mask on, air passes through five important layers of protection before it reaches your lungs. Each layer has a different density in order to filter particles of different sizes. The multi-layer filter technology is tested at the RISE R&D center in Sweden, one of the world’s most advanced filter laboratories, and consists of the following layers:

Outside PP Layer - Outside filter wrapping in a durable finish
Active Carbon Layer - Filters gases and reduces odor
1st Electro Charged Layer - Filters larger PM10, pollen and other allergens
2nd Electro Charged Layer - Filters smaller PM2.5, dust and bacteria
Inside PP Layer - Inside filter with ultra-smooth and skin-friendly finish

The filter is replaceable and lasts for about 100 hours. 

The key to effective protection for an air mask is both the filter capability, and the fit-factor. The mask needs to be both comfortable to wear and also sealed around the edges to ensure that air only travels through the filter. With adjustable components, the Urban Air Mask is designed to offer a perfect fit for most face shapes and is engineered with:

• Adjustable earloops to create a personalized fit around the face.
• Adjustable head-strap for a better fit and less pressure on the ears.
• A 4-size system to fit children, teens and adults.

To further improve the fit of the mask and stop air from sneaking in around the edges, each filter is equipped with a 3D memory nose-foam and an adjustable nose clip that gives the mask minimal air leakage, regardless of one's face shape.

The two exhalation valves on the mask act as a ventilation system, making the mask easier to breathe through. When you breathe, the valves are transporting out the exhaled air to prevent the mask from becoming warm and moisty. The valves are engineered to only transport out the exhaled air, and not let any unfiltered air to sneak in.

In our opinion, design does not need to compromise functionality. Our masks are therefore designed to last. Every mask skin is washable and reusable to make it stay an everyday lifestyle accessory just as long as any other item in your wardrobe. The mask skin of the  Urban Air Mask 2.0 is also treated with Polygiene, a textile treatment that stops the growth of odor-causing bacteria.
