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

Great air filter that traps a lot of dust.

These are great filters though when I picked up the large cardboard box; double the size of the double filter pack inside I was surprised. I opened the undamaged large cardboard box and the shrink wrapped double filter pack inside had obviously been flopping around violently in that box, with no padding/paper/bubble wrap to prevent such. So the rather expensive filters had crushed edges. Terrible packaging which hopefully gets addressed. :/

Cheap flimzy not as marketed. I will not buy these again.

The family was able to quite taking allergy medicine after these were install for a couple months.

Love this level. Makes a huge difference in my allergies!

The filters cut down on dust both visible and microscopic

The filters are fine for my unit and definitely keep the dust down in the house.

Great filters, great quality. Two arrived damaged and unable to use, they gve me half my money back. Im satisfied

As an allergy sufferer, I find these filters greatly cut down on the allergens in the house (not scientifically verified, but just that I think I sneeze less than before I had them). They are well worth the high price.

One of the best Filters to buy.Price is the same as Home Depot & Lowes.
