Review on Enhance Humidifier Performance with Colorfullife 4 Pack Wicking Filters for Honeywell Humidifier Replacement Filters HAC-504AW, HAC504V1, HAC-504 Filter A by Justino Pratama

This is a great deal at a fraction of the price of other products. My youngest gets nosebleeds when the air in her bedroom gets too dry, and running a humidifier year-round can be expensive considering the cost of some filters. They are perfect for moisturizing. The only negative I have is the awful smell of dirty socks when the filter dries up (unless the water is topped up within 48 hours). I'm not sure what's causing this, but we've never had this problem with other filters we've used. If we keep the tank full every day, there will be no smell at all. Now that I think about it, I really hope mold spores aren't thrown into the room when this happens.
