Review on 🌬️ ITidyHome 6-Pack Humidifier Wicking Filters Replacement for Honeywell HAC-504 and HAC-504AW: Compatible with HCM-350, HCM-300T, HCM-600, HCM-710, HCM-315T - Filter A by Brian Messerly

I have bought many filters for my Honeywell Cool Mist and they are the best! I was surprised to see a metal section in the middle of the filter (other filters never had that) but wow what a difference! during the life of the filter. Usually, even turning them over every night, my filters will dry out and the water tank will drain at a slower and slower rate as the filters aren't as effective anymore. With these new filters, the water tank will run dry every day (which means more moisture, hooray!). I cannot recommend them enough.
