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

This is not a true 12x12x1 they are clearly too big

Great filters at a good price.

good

There is one grade higher filter but this one works great will buy again

The filter is not 24x20 it is 24.3 inches which is enough larger that it did not fit. TERRIBLE

Used in my newly purchased older home and in less than a month this is the outcome.(See photo) The air quality has improved. The pet danger is next to nothing. I highly recommend

Comes every 2 months and lasts.

Unfortunately, the ordered furnace filters did NOT arrive as expected; they are damaged and do not fit in our furnace as they should. They are furnace filters????? What the heck happened????

These filters are great at removing dust and other bad stuff from the air in our home. The prices kept going up during covid so I switched to changing every 4 months (instead of 3) and havent noticed a difference.

Fantastic furnace filter. I’ve been using Filtrete for 15 years!
