Wildfire smoke can cause a range of symptoms such as coughing, burning eyes and shortness of breath. More seriously, the smoke can trigger asthma attacks or, more chronically, lead to heart problems and has even been linked to the development of cancer.

Lethal and devastating fires have ripped through large parts of California every fall / winter for the last few years. It is an increasing trend globally, as climate change worsens.

The Cambridge Mask blocks particles down to size PM0.3, and provides the benefit of blocking most smoke particulates, although these can be of variable size. As such, a well-fitting Cambridge Mask should provide a barrier to protect from inhalation of forest fires and other smoke.

Cambridge Mask have been tested rigorously to:

  • pass the American National Institute for Occupations Safety and Health (NIOSH) N99 filter requirements under 42 CFR Part 48 (tested by Nelson Labs USA)
  • 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)
  • EN149 standards for CE in the European Union (Certified by SAI Global and Apave Labs FR)
  • 99.6% viral filtration efficiency and 99.7% bacterial filtration efficiency (tested by Nelson Labs USA)
  • Cambridge Masks have met a wide range of tests to ensure they are effective and safe to use for the whole family.

Note: Cambridge Masks are not firefighting equipment and should not be used to enter/leave burning buildings or when extinguishing fires.
