Heat pump, particularly. Are the cleanable filters the best? They are a
PITA to clean, and I wonder if I get them clean. At a new house I bought, I
have the pleated paper filters. Not el cheapos, but the better ones. They
really catch the dirt. Now I'm confused. What filters the best? The
pleated ones are a little spendy when you consider you change them
frequently, and the washable ones are definitely spendy.

What say ye?

Basic disposables as pre-filter, followed by a proper electrostatic
precipitator air cleaner with grids that are dishwasher safe. Just pull
the grids and run through the dishwasher, and replace the disposable
pre-filter.
