Product review (5 stars): A good aftermarket replacement filter. Will buy these for the foreseeable future
Seller: SupplyBuy, purchased Dec 13th, 2016, delivered on time, product received as ordered.

The Honeywell official filters have some horrible reviews, and only my original filter that came with the humidifier survived over a month. The other official replacements from Honeywell haven't performed as admirably. This filter on the other hand has worked almost as well as my first original filter. No, these are not genuine Honeywell, but they are the only aftermarket filter that I've tried that works as well as they do.

Tips on getting these to last longer: Every now and then, let your filter completely dry out. This prevents mold from building up. If the filter is constantly wet, it's gonna get real gross real fast. Also, if you live in a hard water area, these filters will get clogged up within a week or two. Soaking the filter in vinegar and rinsing thoroughly has worked quite well for me. I've gotten the filter above to last for a month and a half now, longer than the two weeks that other filters here have lasted.
