Review on 🌬️ Fette Filter - Holmes Compatible Humidifier Filter HWF75, HWF75CS, HWF75PDQ-U - Pack of 2 by Tonya Brown

I used to use Holmes pads in my humidifier. This filter looked good and had a good support mesh. It goes well with our HM-3500. The performance was terrible. In operation, the original pads were wet to the brim and after a few weeks performance was reduced by mineral deposits. These filter pads barely got wet to the top when new, and after a few days they were only wet an inch above the waterline. This meant very little evaporation entered the room and no water tanks were used. I wasted electricity, made noise from the fan, and didn't generate humidity in the house. While using these pads, my hygrometer showed a lot less. Don't buy them!
