A wildfire is an uncontrolled fire. Wildfires can burn millions of acres of land at shockingly fast speeds, consuming everything in their paths. These rolling flames travel up to 14 miles an hour, which converts to about a four-minute-mile pace and can overtake the average human in minutes.

Wildfires often start via natural occurrences like lightning, but they are sometimes started by human activity, intentionally and unintentionally. The growth of wildfire is normally determined by conditions and these can include droughts, high winds and hot temperatures. When leaves, trees and shrubs are all dried out, they become catalyst of fuel for wildfire.

Over the years, California and areas of western USA have been badly affected by various types of wildfire.

If you live in an area where wildfire is likely to break out, it’s essential to have a plan in place. Read more on our blog about how you can protect yourself from the wildfire smoke here.


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.

If a person continue to breathe in PM2.5 without a mask, they could experience shortness of breath, nose and throat irritation, excessive coughing, asthma attacks, and reduced lung and heart function. This is why it’s so important to invest in a mask that can filter wildfire smoke out.

The Cambridge Mask PRO can fit tightly to the face, filtering out tiny but extremely dangerous PM2.5. It can filter almost 100% of pollution, gases, and 99.6% of viruses, and 99.7% of bacteria. The mask features a Three-Ply Micro Particulate Layer which blocks out particulate pollution including PM2.5. Our Cambridge Mask also filters PM10, PM0.3, protects you from smoke hazards, and COVID-19, enabling you to stay safe during both the pandemic and wildfire.


Cambridge Mask have been tested rigorously to:

  • 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
  • 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.
  • Particle Filtration Efficiency >98%
