Review on Fette Filter Humidifier Compatible HAC 504AW by Denise Harmeyer

I like to run my humidifier at night (I use the HCM-710). I tried to think of turning the filter either every day or every other day. I also used one of those little Protec fish to keep it clean. It works well and I will change the filter every month and the fish every two months so I can order them at the same time. When it starts looking quite yellow I give the humidifier a good wipe - I think it's probably due to sediment in the tap water where I live. I could use filtered water but it takes forever to refill it every day and I'm too lazy for that. I've never had any problems with mold.
