Fastest ever

My filters arrived so fast it turned my head. I had to check my calendar to believe it. Thank you so much. The filters work very well. I flip them with each reservoir fill, and make sure that I don't let them dry out...if so I just run them under the faucet first.

Perfect

I have purchased cheaper filters that did not last as long or work as well. I thought I was getting a deal with the cheaper ones. Turns out not so much.

Quality- worth the increased cost

So much better than buying generic one from “Wal”. These filters last twice as long and do not mold as much. The extra blue wrapping improves filtration of air too.

Buy the Best - Forget the Rest

Don't settle for the Compatible non-Honeywell filters. I tried a few, but they were either not a good fit or were delivered damaged from poor packaging. Save time and buy the best. Buying from Honeywell was easy and they were delivered on time!

USE THE RIGHT FILTER!

Tried off-brand filters that were less money...they were horrible. Went with the Honeywell brand...they fit right in.
