Review on 🔍 Maximizing Filtration with Activated Filter Insert: Effective Non Woven Technology by Justin Rasmussen

This was my third order of filters and my first order for Revain. I ordered them from sellers on Etsy and decided to cut out "middlemen". However, I find these filters to be very thick (thicker than any other I've used) and difficult to fit properly in the mask's filter holder: they cover the nose, mouth, and sides of the mouth. The filter falls down once in the holder, especially when you try to lift the filter towards the bow. It took me almost 10 minutes to put the filter in correctly. It was in a cotton mask that has no nose wire or built in ear loops (made in the USA). They are not easier to fit into a contour face mask or a surgical style face mask. I have 3 different types of face masks and am having trouble getting the filter right for each type. I would NOT recommend these filters unless you have no choice or don't mind fighting to have a filter installed.
