The science behind TECMASK face masks

Posted on July 22 2020

PM 2.5? PFE? BFE?


Unless you’ve been living under a rock these past few months, you’ll know 
face masks are super important these days and can genuinely protect your health. The outbreak of COVID-19 has made them even more crucial to maintaining top level hygiene for you and your family – although this is not the only reason to wear them. 

Face masks have a huge number of applications including assisting your ability to breathe when there is bushfire smoke and related particles in the air, protecting you against air pollution and blocking cold and flu germs in public places and during travel.  

The big question is: Are all face masks made equal? The answer: A resounding NO. And we really do know, as we’re the experts on this!  

Wearing any kind of face mask or covering (like a scarf) is technically better than nothing, but porous fabric has very limited protective qualities. TECMASK face masks are far superior due to the filter each mask contains inside. To explain why this is so important, we’re going to get a bit technical for a moment, so bear with us…  

We worked incredibly hard to create an amazing PM2.5 filter for our masks – this means that anything larger than 2.5μm (or microns) can’t get through – and a 2.5 μm particle is so small that you need an electron microscope to see it, so we’re talking seriously good filtration 

Our masks were also rigorously tested and certified by the Nelsons Laboratory in the US and they found they were effectively able to block 99% of BFE and PFE particles. For those of us who are not scientists: BFE is a measure of the filtration efficiency of a face mask using viable (live) particles (bacteria) that vary in size from 1-5μm, and PFE is a measure of the filtration efficiency of a mask using nonviable (non-living) particles that are fixed in size from 0.1-1μm.  

What does this all mean? Basically, TECMASKs are super protective and a very valuable tool for keeping you and your family safe and healthy, now and in the future. But please make sure you wear the mask correctly to get maximum benefit -  you can read our mini guide to wearing a mask here.
