About I Can Breathe!

People ask what micron size I Can Breathe! Masks filter. In January 2006, mask designer Adrien had a fit test to determine the size of particles that penetrate each mask. Below is a chart with the results compared to an N95 mask. "N95" is a government efficiency rating that means the mask blocks about 95 percent of particles that are 0.3 microns in size or larger. Particles in the ambient air numbered 33,280 particles per milligrams per cubic meter. For the ratio we divided the number of particles entering the mask by 33,280.

The Air Quality Index (AQI) measures 10 to 2.5 microns of particulate matter (PM 10 & PM 2.5) in the air. The Honeycomb Mask with Carbon filter reduces particulate air pollution of 5 microns to 1 micron by 99% to100% plus the carbon captures chemicals harmful to health. The Silk Comfort Mask filters 99% to 100% of particles as small as 2 microns.

Click here for pollen: "Average size of allergy-producing pollen is 25 microns (one micron equals .000039 inches), but some may be as small as 2.5 microns or as large as 200 microns."   For size of micron see http://en.wikipedia.org/wiki/1_E-6_m  Eg.: Anthrax spore 6 and Bacterium 1-10 microns.  Mold spores measure approximately 2-100 microns.

An Environmental Engineer with broad international experience in air pollution measurement and control, Mark Hodges is Principal Consultant for Environmental Forward Observer, LLC. After evaluating the I Can Breathe! Honeycomb ACF Pollution Mask compared to other masks while on assignment in Kabul and Kathmandu, he observes: The data I have is qualitative from the perspectives of fit, convenience, comfort, durability, and perceptibly cleaner air breathed while using the mask. It's numerous positive features notwithstanding, good fit and seal are essential, and the I Can Breathe! ACF Pollution Mask fits and seals well. Further, it is comfortable, which is very important as people tend to take a mask off after a while if it is uncomfortable or restricts breathing. Mr. Hodges has studied Beijing air quality as well.
