The filter we're using in the furnace is the cheapie one that costs
maybe a buck or less but it only stops the bigger stuff that would
hurt the blower. I would like one that would filter the very small
stuff. Right now the TV screen catches most of the dust. I see many
different kinds but don't know how good they really do. Would
like something below 100.00. Does anyone on here have a good
Consumer Reports likes the disposable Filtrete from 3M. Although you are
throwing away a $15 filter every 3 months, you don't have to wash it and it
works better than many permanent washable filters. Also some of those have
disposable parts any way. Make sure you have an adequate air mover because
a good filter does slow down the air unless it is one of those
professionally installed ones that are several inches thick.
That $15 3M filter is a waste of money. Too air restrictive and it
doesnt perform magic like they'd hope you will believe. Get a pleated
filter, something decent, nothing magical though. Around here, the
Home Depot/Lowes have a 3 pk for about $8 bucks.
Otherwise, get an Aprilaire media filter 2200/2400 or the
electronic/media 5000 uint if that tickles your fancy.

Menards sells a pleated filter for about $2.50 ($1.50 on sale I buy a case
at a time) they claim its good for 90 days I change it every 30 days.I think
that the 90 day filters restrict the air flow, if your house is really
I use these, they are the strongest filter my unit can handle. I change them
every 30 days, mostly cause they come 12 to a box.
Best do some reading on the static air pressure of your unit before choosing
something that might cause problems.
Grainger puts them on sale for about $5 bucks each a couple of times a year.
The cheap filters are what I recommend to my customers most times. The
Grainger pleat says "Recommended Final Resistance 1.0 In WC, High
Initial Resistance 0.38 In"
No residential system I have seen can handle a 1.0" WC final filter
resistance, plus have enough pressure to overcome duct and grille and
coil resistance. Even the initial resistance of .38" WC is too high
for most residential systems. This filter will reduce air flow 10 to
20 % right out of the box. The exception is blowers with Variable
Speed motors, but even they will not be able to handle the 90 day final
resistance of 1.0" WC.
