I have been using Filter Buy furnace filters for 20 years. They are well made and priced right. I change them out every 30 days.

I just received these filters. New to me and need to assess how they trap dirt particles before I can truly rate them. They seem to be made very well and the cost is reasonable.

Recent filter purchase

The 16X25X4 filters were a bit smaller than the honey wells I used to buy (they fit my opening perfectly) I actually had to shim up filterbuys. I can't understand why filterbuys would be smaller than Honeywells.

Im so upset about this

Im so upset about this because I did not subscribe it. Number one in the number two is without my permission. You charge my card and send me the filters when I already have them so that was very disappointing.

Poor Packaging
on February 12, 2026
Posted by: Anonymous
The filters are fine. I am not sure what is going on with packaging but sending four filters without a box with cheap tape is a terrible idea. If this is the new plan for packaging I will be taking my business elsewhere. By the time my filters made it to me the cheap tape broke and the filters were all over the place. Thats a terrible way to cut costs.
