Rated 5.0 out of 5.0 by Dean They fit.
The local Lowes or Home Depot did not carry furnace filters with the true dimensions of "20 IN. X 25 IN. X 4 IN" , so I was glad to find these online at least.
The filters fit into my furnace without issue.
I will order more when needed.
The online shopping selection on the Home Depot website seems to beat Lowes, in my opinion.

This furnace filter slid right into place, and does the job perfectly! The selection and pricing for the online options was great. Absolutely no complaints.

These filters are a great buy in the Three pack and do a great job in the Carrier system that we have. Other places want almost double what we paid for these and in my opinion are not even as good.

Rated 2.0 out of 5.0 by BAP Check dimension size
Seem to be quality filters. However, they at 3.5 inches wide and not 4 inches as advertised. You may have "fit" issues when installed.

Rated 5.0 out of 5.0 by Andrea Works and Fits as expected!
I had originally bought a filter at the store that had the same measurements as my old filter and it did not fit so I ordered these online. They fit and work perfectly with my furnace!

Rated 4.0 out of 5.0 by HomeOwner Very good product, interesting size issues.
I use this furnace filter in my Honeywell air filter and as a filter it performs very well as a replacement for the very expensive brand name filters specified by the furnace documentation. You should be aware of an issue with the thickness of these high performance filters; all of them specify 4 inch thickness but this Probasic filter is only 3 3/4 inches thick and the original Honeywell filters are actually 4 1/2 inches thick. To use the Probasic filter I've had to modify my filter housing with a simple insert to hold the thinner filter in place inside the larger guides. I don't know enough about all the various sizes of filter units and the Probasic filter may fit some units perfectly, but you will need to modify for Honeywell units.

Very inexpensive compared to everywhere else. We got 3 for the price of 1 of the other guys.
