Personally I have always used standard media in my furnace, but that is not what this post is about.
It seems to be a consensus here that washable filters are awful.
Ok. But I want to understand as many reasons why they are awful in comparison to other media.
1. Do they increase pressure drop? Is the airflow decreased through the filter? is this have to do with a non-pleated surface area?
2. How often are these filters cleaned in comparison to the standard 3 month for media.?
3. I have read here that degrade over time. how does this happen?
4. are advertised MERV values inflamed?
tell me some other reasons why these things are awful.
