Filtrete20x25x4, AC Furnace Air Filter, MPR 1550 DP, Healthy Living Ultra Allergen Deep Pleat, 2-Pack (Actual 19.88 x 24.63 x 4.31)

Our unit is very specific. The standard 16X25X4 filters that you can purchase locally do not fit in my unit. I have to use these SLIM fit ones. These are perfect and say they last 3 months. We have a golden retriever so we choose to change the filter more often.

as described--great item--thank you!

Dimensions are correct (unlike some other cheaper brands I ordered), and they do keep air clean during wild fire season. I have been subscribed to these for many years, and a very happy customer.

These seem to be the only filters that really fit properly in my furnace. I can fit slightly thicker filters in but removing them always results in me having to mangle them to yank them out. These just fit.The only downside is that these have gone up by a full 20 dollars (for 2 pack) in just 8 months. That's a bit steep for an air filter.

First shipement was Merv 11s, I ordered the MERV 12s. Ok, things happen, they exchanged no problem. New shipment packed like a 4th grader did it and the filters were in oversize box and the filters were crushed from stacking a mostly empty box in a bouncy truck. I sucked it up and re-folded and repaired the otherwise healthy filter media by bending back all the cardboard frame tabs. A bit pricey too, but it is what it is. Watch the Merv values you recieve. Otherwise a fine product and I recommend.

I have used these same filters for years. They are good quality, and they do the job. But even after years, I still scratch my head trying to figure out how they can charge so much. Other than price, just great.

Had a new air filter installed as part of my new furnace. The cardboard filter provided by the manufacturer did not fit snuggly in the opening so air was going around the filter rather than through it. I purchased these filters and they are a perfect fit. Nice and snug so no air escapes around the edges.

I've been buying these filters for the 12 years since this system was installed. I have very bad allergies. I usually change them every 3-5 months. In those years we've had three dogs and a cat.Today, the old wore out system had to be replaced. When the installers removed the inside unit I took pictures of the fan and the inner coils. Both are amazingly clean. Also the actual ductwork is clean.I highly recommend these filters.

great filtersfilters banged up packaging could have been better

Fits well - make sure you measure the correct size. I didn't expect my furnace to be a "slim" version but it turns out that it is.

Great value, cheaper than I could have bought in any store. No issues with using. Will definitely buy again!
