Does an excellent job of collecting dust. However, depending on your environment, don't expect more than a 60 to 90 day life.

We are happy with it. The filter we had been using was a little bigger and had to be crunched to make it fit. This one went in easily.

[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?

I use these and they really help contain my seasonal allergies.

Wal Mart Had The Best Price.

Great price, exactly what we needed.

These are the best on the market.

This is a terrific price for these filters.

Seems to work well. Much cheaper than the other filters I had been using.

Terrific filters at a great price
