MickinMD ★ Posted March 20, 2022 Share #1 Posted March 20, 2022 I bought a reusable K&N brand, furnace forced-air filter in November and was a month behind the recommended clean-it-every-3-months. So I cleaned it yesterday. The dust catching side was a tan color - I couldn't remember what it originally looked like and I thought that dirt was making it different than the grayer, screen side which looked like this online pic except a little brighter and a little blue: I washed it twice according to directions and using the overpriced K&N spray cleaner. I couldn't make the tan go away. I could blow on one side and feel the air passing through, so I thought it would be ok and I put it back in it's return-air slot next to the furnace, hoping it would be fine. Today I thought: DUH! Why don't I look at the pictures of the new filter on the internet? It was tan! The first, non-reusable filter that was on the furnace also filtered the central air conditioning air and got really dirty in a few months so I expected a dirty filter yesterday: that's probably because of all the dust that first filter collected from and during the house rebuild and then the ultra-clean, new house I started out with didn't send much dust into the filter. The online pics of a part clean/part dirty filter looked like this and mine was pretty clean to start with: 1 Link to comment Share on other sites More sharing options...

Then he proceeded to tell me about high performance automotive filters. 1 1 Link to comment Share on other sites More sharing options...
