    A lot you can say about the poor quality of this filter

    Customer Video Review Length:: 0:35 MinsThis 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.

This of course then cuts in half the amount of wet area exposed to the air stream making the humidier less effective!

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…
