Good quality filter at a good price that fits perfectly in my standard 16x25x4 filter housing. It seems many reviewers are disappointed that they are slightly smaller than the advertised size, which they would need to be to fit in a 16x25x4 case. The negative feedback comes from people who have bought proprietary (non-standard) Honeywell filter housings that are intentionally slightly oversized to discourage you from buying similar filters from other manufacturers. In short, blame Honeywell or yourself, but don't blame those filters for not fitting in your proprietary case.
