💦 AQUA GREEN Replacement HAC-504AW Humidifier Filter: 4 Pack, Compatible with Honeywell HAC-504AW, HAC504V1, HAC-504 Filter A Review

Filters are not as thick as previously ordered and used ones. The mineral builds up quickly, even when using vinegar. The house should be at least 40% humidity to avoid static electricity. These are the first filters that have NOT worked in 20 years.

This product is NOT a satisfactory replacement for Honeywell branded filters. These filters are not rigid enough to maintain the position required to deliver moisture to the humidifier fan. This is a waste of money and in no way worthy of Revain's approval.

This set of two filters costs less than a popular brand filter. They are thicker than a Honeywell filter but still work great for a humidifier. Maybe the extra thickness allows for better moisture wicking? In any case, since it is important to change the filter regularly, an inexpensive alternative will be appreciated.

This filter is nothing more than a Honeywell filter. And it doesn't work. When you first soak the filter, it stretches about 18 inches long, stretches out to its width, and fully deforms to fit your humidifier. It cannot be changed. A complete waste of money. Use original filters.

Added filter layer that looks and feels like felt. This makes the initial water soak difficult before installation and also reduces the effectiveness of my humidifier. With real Honeywell filters, I usually fill up the water tank at least once a day. With this fake filter I only fill once every 2-3 days. I don't think the humidifier is releasing moisture into the air like it should. I won't buy them again.
