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!

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.

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!

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.

We change our filter monthly. Great product. Easy to install and helps with the air quality.
