Collection: Non-Woven Polypropylene Filters Made in Canada

We make our Canada Strong non-woven polypropylene Filti filter inserts in Ontario, Canada using raw materials imported from the USA. We're a big believer in the quality of Canadian manufacturing.

Based on recent studies, Health Canada now recommends adding nonwoven polypropylene filters to cotton / cloth face masks to improve the performance. Our Filti filter inserts go the extra mile combining non-woven spunbond polypropylene with a unique nanofiber filter layer. Filti's next-generation ePFTE material is MERV 16 rated and has typical 99% particle filtration efficiency (ASTM F2299) per Nelson Labs LLC, Salt Lake City, UT. 

And best of all, our lightweight filters are very breathable. They're more breathable than PM2.5 activated carbon or HEPA filters. Breathability is key for comfort when wearing a filter for extended period of time.

Our filter dimensions (3.25" x 4.75") are identical to a standard PM2.5 and will fit any face mask pocket. For child's size, the nonwoven material trims easily with scissors. 

Improve your cloth mask performance with filtration technology from Canada Strong and Filti.
