Humidifier filter removes mineral and pollutants from water. Filter discoloration is natural and will carry depending on water. Replace filter about every two months (depending on use and local water quality) or when performance starts to deteriorate. Help keep your humidifier clean and extend filter life by using other Honeywell accessories including antibacterial treatment (HAC100). This helps control bacteria and algae growth in your water tank, and provides odor free operation for use in evaporative humidifiers only.

No more shopping from Allergy Be Gone:
The filters I received were BestAir HW500 (1 of 4 was in the original box). They have a metal shell versus plastic on the original Honeywell HAC504. I returned them and received another set of filters which were again the same filters(HW500) I believe. They had no original box and the shell was metal, which can easily scratch its housing and stimulate mold growth in humidifier.
It is also sad that I saw another review sent on October 2007 about similar problem(purchased as HAC504, received different)... more info
Honeywell Confusion:
This product works well, but it's just a bit confusing on which specific one to buy. I have an older discontinued model of humidifier and while I have no problems with using this filter with it, just plugging in the model connects you with many filters and they all look the same, but the one that I purchased did not like the picture shown. Again no problems with using it, just like to see a better way to find the right one.
