Product review (4 stars): Definitely superior to Honeywell's replacement filter
Definitely superior to Honeywell's replacement filter. This thick filter can last 2 weeks to 2 months depending on how often of you use it and type of water. We have used it for 1 month and looks like it will need to be replaced in a few weeks. Best filter I've used for our Honeywell HCM-350 thus far.
