Good long life filter at a good price
A few years ago I switched to the Honeywell product similar to this.  Last time I bought, though, the 5&#34; filters were now 3&#34; for the same price and claimed to be just as affective.  Hmmm.  After the Honeywell filters were completely clogged in what seemed like too short a time, I sought an alternative that might still be full size.  These are my new standard.  They fit the 20x25 frame better than the Honeywell filters, and I noticed an instant difference in the air flow (of course the Honeywell filters were at or beyond the end of their useful life.)  Officially the claim is a year between changes, but I change every six months.  I just hope this company sticks with 5&#34; filters and doesn't get greedy like Honeywell.
