Merv 11 paper the best
Our filter is supposed to be changed annually. At best your washable filter is Merv 8 runs anywhere between 130-150 dollars and will lose efficiency over time. A Merv 11 paper filter 20x20x 4 is only $30 and is much more efficient.
To even consider a washable filter, ask yourself how long you plan on living in your home. Then calculate lost efficiency and the probability that it will end up in the trash sooner or later. Most have their ducts eventually cleaned anyway within 5 years?
