This house had a monstrous filter on the HVAC unit in the attic when we bought the house; only needed changing once a year. However, air was leaking past that filter, and the evaporator coil had a tiny leak. So last month, my HVAC people replaced the evaporator coil under warranty, but then I let them replace that filter and the housing, etc. with a Honeywell filter with a MERV 11 rating, and they cleaned all the ductwork. I know many say that "usually" duct cleaning is a scam, but I think ours actually did need cleaning, especially since my wife had COPD. I think this new filter will be replaced every 6 months.
And like Eddie, I pour a little bleach down the condensation drain once a month.
