Home HVAC filters

[Donald]

I have been using the cheapest pleated filter I can find, but was recently told by someone in the industry that even they are too restrictive and they recommend the el cheapo fiberglass filters. He claimed they filter well enough and are much less restrictive. Thoughts? It seems opinions vary, some pros recommend the cheap pleated filters and others recommend the fiberglass ones.

Yes, I have an Aprilaire system on the Carrier air handler in my Florida house. Since Covid, the price of a four-inch 410 replacement Aprilaire filter has gone from $37 to $54. At least they are good for 12 months or more in a clean home without pets and where windows are rarely opened.

I think they change mine 1X a year. The heat pumps get serviced 2X a year.
