Filtration and Fit

Hello all,

It has been a good long while since we've blogged about anything...but here we are again amidst another lock down facing similar issues we did when I wrote about our filters way back in November of 2020. So here is a reprise of that post with a few added tips about keeping your mask tight fitting to increase it's efficacy.

Just over a year ago Health Canada had just announced that a third layer of protection was recommended for masking.  As part of that announcement, our intrepid Chief Public Health Office Dr. Tam said that, "We're not necessarily saying just throw out everything that you have," before suggesting adding a filter (to a two layer mask) can help with protection. 

Of course the WHO (World Health Organisation) had already recommended a third layer which is why in part we designed all of the commUNITY masks to have a space for a filter. So now adding one of our washable filters to your two layer mask keeps it compliant with all Health Canada Guidelines. Here is the link to that updated guide. 

Our washable filters are made from a non-woven polypropylene. This is the same material found in most N95 masks. It is completely safe, breathable and the preferred material that Health Canada cites for use as a third filtration layer.

Here is a link to an article from the National Academies of Sciences Engineering and Medicine discussing various filtration materials and their efficacy. It is a bit wordy but essentially it says that non-woven polypropylene is a very effective material in filtering smaller airborne particles while still allowing the user to breathe.This is why the N95 masks are almost exclusively made from this material.

And now to the bullet points about our filters...an absolute must for any self respecting blog: 

  • Thin, highly breathable but offer very strong protection
  • Made from Non-Woven Polypropylene
  • Anti-microbial and anti-bacterial
  • Designed to fit in both kids and adult masks
  • Washable up to approximately 30 times
  • Cheap and easy to use   

Your filter needs to be washed after every use. We recommend you keep the filter in your mask when putting it in the washing machine and dryer. If you're hand washing then remove it and wash and dry separately. 

While filtration is the most important feature of your mask...the fit is definitely the next most important. In both the above linked articles, two of the recommended ways to improve the fit of your mask are offered on our masks! A flexible thin metal strip across the bridge of the nose to keep the mask from sliding down your face and a way to adjust the tightness of the mask. The reason we offer adjustable toggles as an option and not standard is because many people don't require them as the fit is tight enough. But for those that have smaller features, our easy to use toggles are a perfect way to make sure your mask fits perfectly.

We are all tired of this virus. It has taken an unimaginable toll on our lives in so many different ways. I know one day soon we will put this all behind us, but arming ourselves with the right information and the right tools to conduct our lives is all the more paramount now. I hope this blog has helped on both those fronts.

That's all from me,

Stay safe...wear a mask...with a filter!
