Great filter... If it fits!
I'm not sure how the 5-star reviewers are using this filter, but my AC register is made for inch-deep filters. I'm used to buying 4&#34; deep Honeywell filters with a 1&#34; lip on them, allowing them to fit into the register. Without that lip, a filter (like this one) will just fall into the intake plenum. Which makes them utterly unusable. I'm not faulting the seller, other than omitting the rather important fact that it has no 1&#34; lip.<br /><br />If you're looking to replace your 1&#34; filter with this, I advise you to keep looking.
