Product Description

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.

1.0 out of 5 stars Beware from buying from Allergy B Gone, October 20, 2007

Thought I purchased the Honeywell 504HAC replacement filter as listed on Amazon, but instead received a generic version that I could have purchased for significantly cheaper. I phoned the company but got no answer. I emailed the company and got no response. Would avoid any transactions with this company. I placed a complaint with Amazon and hope that this problem can be remedied.

2.0 out of 5 stars Be warned, the filter is a GENERIC replacement for the HAC504, December 13, 2008

OK, so I should have read the reviews before purchasing. I would have seen from the first review that this is not made by Honeywell itself.

The product details says "Item model number: HAC504", the Honeywell model number.

I received a "Best Air HW500 Humdi-Wick". Best Air Humidifier Filter (HW500)

I don't like being bait & switched, so I am dropping the rating down to 1.

But the price for the HW500 with a few minutes of online searching was, at it's cheapest, $1.50 more, and even on amazon from a non-misleading item search, was $3.50 more. And the company did ship pretty quickly; it arrived 3 days after the order was placed. For that, I am raising the rating to 2.

I have no review on how well the HW500 will work in the Honeywell humidifier yet. I am going to go ahead and use one for a couple of weeks to see how well it works. I will say that the diameter is smaller the the HAC504, but I am not sure if that will make a difference. If it works OK, I will come back and raise the rating to a 3.

To the seller: To get any higher, I would need to see some indication in the main product item page that this is a GENERIC filter instead of a Honeywell brand item.

Works Great. The handle that they put on the filter is really just a gimmik, but they also changed the outer most layer from paper to a tough plastic. It lets you soak the filter in hot water to get the minerals out. It looks like you can reuse it at least a couple of times.
