Our PM 2.5 activated carbon filters easily fit into the inner pocket of our cotton fabric face masks, adding an extra layer of protection from air contaminants such as pet dander, pollution, dust, and of course all that wildfire smoke that's out there these days!

The filters are made from five layers of non-woven fiber, and a middle layer of activated carbon material.

Face mask Filters - PM 2.5

These provide a lot of filtering power and are easy to insert into T&D mask pockets. Gives peace of mind when encountering many people in a somewhat confined area. This is a great product.

Very handy filters for reusable masks

These filters are easy to insert and stay in place no matter how much I'm speaking. I'd recommend this product to everyone, especially with Top and Derby's well-designed masks. I'm a very satisfied customer of the filters and masks, and especially my Chatsworth walking stick from this Canadian company.

Extra layer of protection

The mask + filter is very comfortable. Did wonder if the mask would feel restricting with the filter, but have not found it so. Most comforting to have the extra layer of protection.
