I'm thinking the electro static ones are a bit more expensive than the 2 types I listed in my OP.I'm not positive, but I think the electrostatic filters are supposed to give you the filtering of the pleated, without the reduced air flow that pleated results in. Those spun fiberglass filters are all but useless for reducing dust in the house. But that's it right there - if you don't have an issue with dust, why filter out what doesn't need to be filtered? Just a couple weeks ago, I finally convinced my wife to just put a box fan in our central room of the house, and leave it running - I placed a pleated filter behind it. The air flow (pressure difference + friction) holds it in place. After just a week, my wife was amazed at how much dust it captured; the filter is filthy. (Some remodeling work going on; lots of dust had been created.) And, my wife is commenting on how much less dust is on the furniture. It didn't have to be changed, but she already went out and bought 3 or 4 more filters, and changed the filter. I'm planning on testing out the electrostatic filters once summer rolls around and more air circulation would be nice.
lowes/home depot doesn't have fiberglass filters eitherUnless you have allergies just use the fiberglass ones. Any home improvement store will have them for 50-99 cents each. I just buy them by the case for <$10.
Tennis balls.and what does the spun fiberglass filter out then?
Do you live in a communist state that has banned them or something? Could be BS but the guy who installed my HE furnace said not to use the pleated as they cause the fan to work harder.I'm thinking the electro static ones are a bit more expensive than the 2 types I listed in my OP.

There's some truth to that. It gets even worse if you get the fancy allergen controlling ones and try to force your HVAC system to be an air purifier. Use an actual air purifier for that and don't put that load on your HVAC system.Do you live in a communist state that has banned them or something?

Always to an extent. Looking at the MERV rating as well - the higher (which filters more) the lower velocity of air that goes through. I'd never put a MERV2 or a MERV18 (if they make either or) in my systems...the ones I normally get around around mid-range. (8) Considering we just got done w/ a kitchen reno and I changed both filters - the thing was completely grey and caked in dust.There's some truth to that.
