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 Karl Swift

This filter is excellent. I've been buying replacement wick filters for my humidifier for years, and usually after the first few patches the filters get damp and sluggish and can't stay in place. Worse, sometimes parts of it start falling off. And I usually let them dry completely because I keep forgetting to refill the humidifier so it HARDLY dries out. These filters have a metal layer in the middle which makes them more durable and helps them keep their shape. I actually had 30 days instead of 8 or 10 days like the others before I had to start getting them in shape. I would absolutely recommend it if you use your humidifier as badly as I do. And even if you're not.
