    • Perfect
Style: 20x25x1
⭐⭐⭐⭐⭐ (5/5 Stars) – Excellent Air Filter, Works Perfectly! I recently purchased this air filter, and I’m really impressed! It was super easy to install, and I noticed a difference in air quality almost immediately. The filter captures dust, pet dander, and other allergens effectively, making the air in my home feel much fresher. The build quality is solid, and it fits perfectly in my AC unit. Plus, it runs quietly, which is a huge plus. Compared to other filters I’ve used, this one lasts longer and offers great value for the price. Overall, I highly recommend it! Will definitely be purchasing again. ... show more

The Filterbuy AC Filter is an excellent replacement for my HVAC system. It fits perfectly and was super easy to install. I love that it’s made with high-quality materials, and it does a great job of filtering out dust and allergens, helping to improve the air quality in my home. The price is reasonable, and it lasts longer than other filters I’ve tried. Highly recommend it for anyone looking for a reliable and efficient AC filter! ... show more

    • Great buy if they would have had sufficient packaging material.
Style: 16x25x4

Other than the fact that the original order had crushed furnace filters and no packaging material, the replacements were fine. I have ordered these same ones before because they were reasonably priced and worked just fine in our furnace.

    • Great purchase!
Style: 16x20x1
These air filters are easy to install, reasonably priced, and arrived in good condition—just as advertised. The multi-pack makes it simple to stay on top of replacements, so my HVAC isn’t working harder than it needs to. Solid quality and convenience earn this product a well-deserved four stars!

    • Great filters at a good price….
Style: 20x30x1
I had obviously ordered this 4 pack because it was time to change our HVAC filter. My biggest reason was that while the filter says 20x30x1, in the fine print it points out that the filters are actually about a 1/2” smaller in the length and width. What this does is allows the filter to slide right in the grill frame with no problem. Lots of times you get a filter that is the exact same size as the grill opening and won’t go in without a big hammer (just kidding, but it is a real pain). The filter construction seems more than adequate to prevent it from coming apart and getting sucked into the air handler. That’s not a happy time for any homeowner. In the end, I liked the fit and construction so much that I put them on a subscription. Highly recommended! ... show more

    • It really works!

By far the best air filter I have found! It fits perfect and really works on trapping dust.

    • Great filter but just did not fit my furnace.
Style: 20x25x4
This filter specs are great. I unfortunately have a furnace that did not allow this filter to fit properly. I am reordering this filter in a smaller size. After looking at the way and material used to make this furnace filter, I am impressed with the workmanship and quality.

    • Great Quality Air Filters that Fit Perfectly!
Style: 16x25x2
We have been using these filters in our house for over a year and I HIGHLY RECOMMEND THEM! When I say they get the job done, THEY GET THE JOB DONE! Yes, Price and quality match and there is a big difference in the $4 air filters and these ones. Every time I change it out, it is a disgusting BLACK which means its catching way more dirt and dust. The filters i've had in the past have never looked like that which means that we were breathing in that nasty crud. The dimensions for our air duct are a little atypical and the dimensions we needed were hard to find at our big box stores. I am so grateful that we found the perfect size to fit on here. If you or your anyone in your family suffer from airborne allergens, then these are a must for your house. ... show more
