I've been using the disposable fiberglass filters for a while now. They catch a lot of dust... last about a month or so.

I've been thinking about moving to the washable filters, so I don't have to worry about running out of filters or remember to buy them. It seems like the electrostatic ones are a little more effective.

I'd like to keep it low-cost: I don't want to spend a bunch of money on a filter, especially throw-away.

What type of furnace filter do you use?

disposable. And you're supposed to replace them every month?

In my experience the residential electrostatics are NICE. But personally I buy pleated filters in bulk from either Grainger or the local HVAC supply house. Affordable reusable filters aren't that effective.

Step up to a pleated filter for a 3 month period and you'll eb pleasantly surprised when compared to a fiberglas filter. I modified my home unit to accept 2" filters as opposed to the thinner residential filters. Surface area is much greater than the thin ones. I can go 6 months to a year on one filter.
