Honeywell Humidifier Wick Filter, Single, HAC-504AW

I don't even know why they still make the non-airwashing filters. These Honeywell HAC-504 Replacement Filter for Honeywell Humidifiers really do take a lot of the dust out the air, but more importantly these filters holdup a lot longer than the HONEYWELL/ENVIRACAIRE HAC-504 Replacement Filter Pad ones do, and they really aren't that much more expensive. These filters are mislisted though, their real part number is HAC-504AW, the "AW" is for "Air Washing", because for the blue layer of filter material.

We run two humidifiers all year round here--it's dry in the desert--and these filters are MUCH better than the reg ones. It's worth a little more to get these. That blue stuff on the outside helps them last longer and filter the air better.

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!

I just received my Honeywell filters. I ordered from Amazon.com last time and got a much better quality of filter than the one sent with this order. This time the product came in a green box with premium replacement filter on the outside. However the quality is not nearly as good as the previous product which came in a blue box. These are both wick type filters but they are not made the same. The inferior one has less thick washing layer and it isn't as dense. The inferior product weighs 1.5 ounces and the product I received before weighs 3 ounces. As you can see someone is trying to pass off a generic product for the same price. I am very disappointed in Amazon for going a long with this. Now I will try and return the inferior product and this is a big hassle for me. I find it hard to find these filters so I order them online. I will also complain to Kaz Incorporated about the inferior product. I paid 12.99 a filter so I could get the better quality filter. I did not get the quality I paid for!

I wrote Amazon about the product and they sent me a shipping label to send the package back free of charge. I am to get a refund in about two weeks. They also gave me 5.00 coupon for my next order. I have spent a lot of extra time writing them, writing this review, printing labels, repackaging the item and will still need to drop it off at UPS.

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.
