Review on Fette Filter Humidifier Compatible HAC 504AW by Bob Berry

No problems with the first filter. When I was ready to switch to a new filter, I opened the box, took out the new filter and saw that it was covered in mold. The house is constantly low-temperature air conditioning with humidity below 30%. This is unacceptable. Don't waste your money, buy another brand filter. **UPDATE** 05/12/2018 Unfortunately I had to order this filter again because other brands were causing problems. Voila! The filter failed me again and soon after a week I got mold. Upload a new photo. The only pity is that it is almost impossible to find a trustworthy filter. I think I will look for another brand again (?).
