Review on Fette Filter Humidifier Compatible HAC 504AW by Steven Darkshnar

Like many other similar filters on the site, I had it for about 2 weeks and it was almost out of life. This requires extra care, turning them over every night and soaking them every few days before operating the humidifier. Every night I turn on multiple humidifiers in all of our bedrooms. They all seem to work the same way. I can't remember what the original filters were, but I do remember being able to use these filters for over a month with no problems. I wish I could tell what has changed. Maybe it's the size and/or the quality of the material. If anyone finds a seller worth buying I'm open to suggestions otherwise I think I'm stuck buying for now. FYI, I don't have mold. Problems like others have been raised via other sellers but the filter is turning yellowish I think it's drying out at the top of the fan although I never run it fully dry.
