The filtering & wicking features work well. 3 dogs sleep in our room so the filter is necessary. Recently I ordered some off brand accidently & they are garbage. These are the best!

These filters work in the open style humidifiers and they function well. This style humidifier prevents white dust. The filters last for months when using filtered water.

I recommend buying this type of filter from the manufacturer. Imitations found on other sites mold and are not worth the expense. This filter was delivered quickly and the price was competitive. I recommend purchasing directly from Honeywell. It was easy to register and order.
