Independently Tested Filter

  • Certified as child safe under 14 U.S.C 1278a and CFR Parts 1370 1501 1500.53 and 1500.44 (Certified by Bay Area Testing Labs)
  • 99.6% viral filtration efficiency and 99.7% bacterial filtration efficiency (tested by Nelson Labs USA)
  • Particle Filtration Efficiency >98%

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.

    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.

    For all the details of the filter’s lifespan, check out our FAQ page.
