Product review (3 stars): Good Replacements With Proper care.
Decent replacement filters. I find that to keep them lasting a long time, I have to make absolutely sure my humidifier does not run dry. Sometimes I'll take the filter panels out and run the filters under water to keep them soaked good. Once they start to dry out the ability for the filters to stay moist begins to rapidly deteriorate. Keeping them wet is essential to longevity.
