Featuring an advanced and uniquetriple filter system, the reusable Cambridge Pro is the premier, designer respirator mask for high particulate matter (PM 2.5)
The PRO Mask 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 PM0.3.
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.
A Mask for Everyone
The masks have a wide range of uses but are often utilized by travelers, cyclists, urban residents, respiratory disease sufferers or anyone wanting to reduce exposure to potentially harmful pollutants.
Washable and Long Lasting
The Cambridge PRO Mask can be used for up to340 hours depending on the level of pollution it is exposed to. For the average customer, this is around 3-6 months of wear.
The mask can be washed with soap and hot water, however, keep in mind that this will not extend the life of the filters. We wash ours in the kitchen sink
Please note that Vogmask is a reusable mask with the filtering textile sewn into the middle of the mask. The small disk on the side of the CV masks is a one-way exhale valve.
