This filter appears to be a genuine Honeywell filter but is much thinner and does a poor job of evaporating the water. The previous filter would empty a 1.5 gallon tank in 24 hrs. With this filter it is 1/2 full 24 hrs. later. See my video for direct comparison. I suspect the other 1 and 2 stars reviews do not realize this is a different filter. I searched the box and both say Honeywell HAC-504aw. It appears to be made by Honeywell. Honeywell go back to the old filter or I will get a different brand of humidifier.

If you live in a dry place or a place where your heating system dries out the air in your house in the winter, you probably rely on one or more humidifiers to keep your home comfortable and shock free. I have been using a Honeywell machine with this filter for three years now. Each winter I purchase about 10 of these filters to last the whole heating season. However, this year I noticed something new. Honeywell had clearly reduced the bulk of these filters. When I installed them I noticed the first night they were operating at about 50% less capacity than the very same filters I purchased last year. The older version used a full tank of water overnight when new, while this version uses only a half tank. That means a dried out nose in the morning, dry skin and static electricity that sends the cat running anytime you touch it. Thanks Honeywell for taking what was a good reliable product and making it ineffective. If you don't want to replace your humidifier, look for an aftermarket filter. That is what I am going to do.

For years I have been delighted with these replacement filters for my Honeywell humidifier. Unfortunately the manufacturer has recently made a product change that I find very disappointing, the filter's thickness has been reduced in half - while keeping the price unchanged. This of course then cuts in half the amount of wet area exposed to the air stream making the humidier less effective!

Yep really crappy filters that are half the size of before.

So you get the following "Features"

Half the life
Half the durability
Half the moisture output

ALL FOR THE SAME PRICE!!!

What a deal /sarcasm

Update:
So I wrote to Kaz about the filter change and here is what they said:

ear Consumer,

Thank you for your recent email.

Due to our product dimensions we were forced to minimize the size of the filter your humidifier uses. We have many Honeywell units that use the HAC-504AW filter, and unfortunately, due to the filter thickness we had several units that were having a lot of trouble fitting the wet filter. There were many accounts where the filter would cause the tank or housing not to sit correctly, where it would get caught on an internal humidifier part, or where it would absorb more water than the fan could take off of it efficiently.

For these reasons the new filters have had a few layers removed in a way that allows them to fit and work much more comfortably in all of our units.

However, the thicker style is still available to order using the information below.

Part Number: HAC-504OS $12.99 USD

Telephone: 800-477-0457 (M-F 7:30AM-7:00PM EST) with Visa, Mastercard or Discover (All of US and Canada). Our winter "order department" cannot take this order, so please do not push the "to place a new order" option. Please push option 4 from the first menu and then press option 7, which will direct you right to a Consumer Relations Representative who will be able to take the order. If you choose the "to place a new order" option from the main menu they will tell you they cannot take this order.

I am very disappointed in this replacement filter. I put it in my humidifier, noticing it was noticably thinnner but thinking it probably didn't matter. My humidifier put out significantly less moisture. I thought my humidifier was just getting old (which it was) and replaced it with a new one, HCM-630, which worked much better. (My new humidifier came with a MUCH thicker filter which I used.) I ended up buying another HCM-630 and put one of these replacement filters in it just to test it out. The new humidifier put out about HALF the moisture with the thinner replacement filter. I thought I had a humidifier problem, but i had a filter problem (expensive mistake!) Anyway, I think the manufacturer should say on the humidifier, "3 gallons of output a day WITH THE ORIGINAL FILTER ONLY" (you can't buy a "replacement" filter that's as thick as the original one... this HAC-504AW is the official replacement). I am going to be calling the manufacturer to complain.

Got a couple of these last year and they were ok. This new one I just got is crapping out in like 3 weeks and won't absorb water at all now. I feel totally ripped off by Honeywell - I will not buy honeywell crap at all going forward if there is ever an alternative. What a screw job this filter is!!

I don't know what to say about this filter other than W T F?! Honeywell & Amazon? I put this into a clean and sterilized humidifier on 1/10/15 and tonight 2/20/15 I had to remove it due to copius amounts of black mold. I started smelling mold last week, and laughed at myself because I thought it was just a banana peel I had set on my nightstand. But, no. The smell of mold is unmistakeable and when I attempted to refill the unit today I thought I ought to take a look inside.

BLACK MOLD, GUYS. I used regular good Lake Michigan tap water, no weird additives and I only used it about 10-15 nights since I got it.

The other people here who have said these "updated" versions of the Honeywell replacement filter don't wick the water as well are SPOT ON. It takes FOREVER to use up a tank, which means basically little water is getting into my bedroom, oh and did I mention the black mold?! The unit worked perfectly with the original filter, and the unit is in great shape. Basically I am saying this isn't user error. I have a mold allergy and have been sneezing for two weeks, guess I found out why.

Apparently I am too late to return it, doesn't that just figure.
