PM 2.5 Activated Carbon Mask Insert

Here's a link to the most up-to-date Health Canada guidelines about masks - https://www.canada.ca/en/public-health/services/diseases/2019-novel-coronavirus-infection/prevention-risks/about-non-medical-masks-face-coverings.html

Since my masks are carefully made from 2 layers of premium, tightly-woven cotton, plus a nonwoven layer of interfacing, a filter is not necessary, but there is a pocket to add a filter, if desired.

People have been asking for the option of adding some replaceable filters for their order to try out so I am including this listing as a convenience, but I make no health claims about the filters and I did not make them. 

They are imported from China, and are a single-use disposable 5-layer paper filter with activated charcoal, and they fit well into my handmade masks but are totally optional.

They are about 4.5 inches long and 3 inches high.

If they are popular I will bring in more and be able to get the price down, this offering is just to gauge interest.
