Review on 🔍 FILTI 20x20x2 Pleated Furnace Filter by Genene Locson

I ordered this filter for our office building, we were concerned about the general air quality in an urban environment and close to major thoroughfares. Obviously, especially in our days with the "Rona". Regular MERV 13s with "electrostatic" filter media get dirty quickly, and then you can see dust and debris discoloring the back of the filter and appearing like it's going through the filter. Touching the back of the filter will get your hands dirty, so we're pretty sure they won't pick up much liquid. Apparently these filters use nanofibers for mechanical filtration, which means they have a very dense network of fibers so dirt that gets on them can't pass through them later. Our system reads the limit and they measure the same as our other Merv 13s, which is good to know. Glad to see how it works, but looks good so far!
