Filtrete 20x24x1, AC Furnace Air Filter, MPR 1900, Healthy Living Ultimate Allergen, 6-Pack (exact dimensions 19.81 x 23.81 x 0.78)

3M is the gold standard of household filters. My church has 3 HVAC systems. We plan to reopen on Thanksgiving 2020, and these new filters were installed. We did not reopen. By April 2021, it is time to replace the filters. Here is the picture of old vs new. The price of these filters has come down and I will be using these filters from now on and my own house.

Excellent filters. Arrived shrink wrapped. Recommended by Consumer Reports. Arrived quickly and easier to receive from Amazon than checking more than 1 store for unusual size. All 3M products work great.

Nice filters, highly rated.

I adjusted the flame down quite a bit but the 1965 Heatwell (that worked wonderfully with ACE hardwares cheap prob merv 600 pleated filters) keeps shutting down now before the chosen temp is reached on the thermostat. I called 3Mtoday and they said this is the least restrictive of all we make reah right....

MY husband was suffering from bad allergies/asthma. There is a lot of dust in our area from the outside due to all the construction going on and where we live. There would be a ton of build up all around the house, since purchasing these filters, he hasnt had any issues. Great product, just a bit expensive.

These do just what they are supposed to. They are good filters that pick up a lot. We have them up on subscription order and replace them about every other month.

Well constructed. Traps harmful particles in the air. My go-to filter for exceptional air quality.

Works great

The filters work well at stopping dust and allergens.

I use theses filters because they capture allergies! they were such a value I bought enough for a years worth of replacements.
