We use 5 different layers in the filter for the Urban Air Mask 2.0. 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
