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

...from the effects of a dense regional pollen environment and a never-ending supply of the fallout from an exuberant short-haired dog and a long-haired cat. I replace this filter every other month. When I see what is trapped in the filter element, Im glad its not in our air or settling back on to the floors and furniture. Obviously, no filter is going to make a house dust-free. But when running a heat pump for summer cooling and winter heating, anything that reduces the particulates is a welcome bit of assistance.

Seems to remove household odors and dust. I’m a believer.

I gave 5 stars, but I ordered the wrong size. LOL They are great quality and I appreciate the help in allergy prevention with the larger ones I ordered that were the correct size. I made the mistake for the smaller ones, not the seller. I need 14 x 14 x 1

Yes they are great filters but are pricey

When these 12X12 filters arrived we realized how overpriced they were at $34.21. Buy elsewhere if you can.

The air filters are strudy and easy to replace

My home is easier on my sinuses during allergy season because of these, in addition to vacuuming.

very pleased

Not much to say about it except it’s doing what it’s supposed too.

Restricted air flow too much. Our furnace couldn’t run correctly.
