Filter width changed without proper labeling
on August 10, 2025
Posted by: HonestFeedback
[This review was collected as part of a promotion.] I have been purchasing 16x25x4 filters for years. 3M recently changed the filter design (thick paper stock casing has no diagonal elements) but also the width. As a result the filter width is 1 centimeter too narrow and thus leaves a gap through which unfiltered air can go into the blower. My observations are consistent with what another user's review from early August 2025 is describing, and their photos clearly show the difference in width between the previous and new designs of the filter. At the very least you should indicate clearly on the label that the filter is narrower than previously. I know you made 2 versions of a 16x25x4 in the past (regular and slim; the regular version fits my furnace). Are you now only making narrow versions?

16x20x4 does not fit Honeywell / Lennox filter box
on March 4, 2025

Buyers beware: The actual size of the 16x20x4 was reduced at some point last couple of years. As the result it doesn't properly fit in Honeywell / Lennox filter boxes, despite the advertisement on the packaging. The filter size used to be 15-7/8" x 19-7/8" x 4-5/16". The new filter size is 15-7/16" x 19-3/4" x 4-5/16", so it is 7/16" (1 cm) narrower than the old filter.

I need a 18x20x1 1900 filter but Filtrete doesn't make one, settled for a 1500 but not satisfied. Found an Aerostar filter and an evaluating it, but would prefer Filterate for good quality control and honest rating assessment.

This is the only product I purchase for our furnace. I particularly like that it only requires changing once a year. When we changed ours for 2024 we discovered that it could have remained in place longer.
