Cambridge Mask – The N99 Pro Mask
The filters used in Cambridge Mask Pro meet the N99 Standard (higher than N95). This is a US Government specification for pollution masks. The masks use a triple-layer filter which will protect from a range of airborne contaminants.
Filter With British Military Technology
The mask uses a unique triple filter system. The first layer catches larger pollution particles such as dust and PM10, followed 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 a 100% pure activated carbon cloth, which was originally developed by the UK Ministry of Defence for chemical, biological, and nuclear warfare protection.
The carbon filter is also treated with silver to ensure almost 100% harmful pathogens are removed and killed. The unique filter system allows the Cambridge Mask to perform better and last longer.
