The Churchill Pro Ventilated Respirator Mask
Cambridge Masks ™ filtration system incorporates particulate filtering layers and military grade carbon. The Cambridge Mask PRO meets the N99 (one step up from N95) standard and is built to filter out 99.6% of particles, bacteria & viruses in the air.
What’s In The 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 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.
This multi layered filter system means the Cambridge Mask performs better and lasts longer than other masks on the market.

Long Last Filter and Washable Mask
The PRO Mask can be used for up to 340 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.

How to use the Headstrap and Nose Foam
The head strap clips to each ear loop then goes around the back of the head, reducing strain on the ears and tightening the mask on the nose and chin.
The nose foam can be stuck inside the nose section of your mask to increase comfort and prevent fogging up of glasses in colder weather.
