Cambridge Mask PRO is a fashion focused pollution mask that comes in a large range of designs and 5 different sizes to fit comfortably for both children and adults.

The Military Grade Filters used in the Cambridge Mask PRO meet the N99 Standard (higher than N95). This is a US Government standard specification for pollution masks. The masks use a triple-layer filter which protects the wearer from an extensive range of airborne contaminants.

What’s In The N99 PRO

British Military Grade Filter

The pro mask uses a unique triple filter system.

The first layer of the filter system catches larger pollution particles such as dust and PM10. It’s then backed up by the Three-Ply Micro Particulate which stops nearly 100% of smaller particulate matter such as PM2.5 and PM3.0.

The inner filtration layer is made from 100% pure activated carbon cloth, originally developed by the UK Ministry of Defence for chemical, biological, and nuclear warfare protection.

The carbon filter is treated with silver to ensure 99% of harmful pathogens are removed and killed.

This multi layered  filter system means the Cambridge Mask performs better and lasts longer than other masks on the market.
