My Wife and I purchased the Honeywell 99.9% Germ Free Humidification Cool Moisture Humidifier for use in our bedroom last year. We are very satisfied with the product as it make the room extremely comfortable. We subsequently purchased the Honeywell HAC-504 Humidifier Replacement Filter, Filter A, as the initial filter required replacement. The new filter also performed extremely well, making the Humidifier perform as if brand new. I recommend the Humidifier and replacement filter unconditionally and without reservation! Sincerely, Mike Durica

These filters are great! The newly redesigned filters last longer and definitely seem to filter the water better. Definitely recommended!

I like the humidifiers, but not the over-packaging and I definitely did not like Honeywell telling me my cc was not working when it was as you eventually found out.

I bought this filter to replace the filter that cam with my HCM-350. Not only did it work, but it has allowed better water absorption. I would suggest the filter to any user over the original filters.

A little while ago I noticed my humidifier filter had gotten more blue and with that I find it has done an even better job than the old ones which were all yellow honeycomb. I run the humidifier every night so I go through my share of these. I would never buy generic.

It's always a plus for me anytime I can order a product direct from the manufacturer for a good price. And, I especially like the fact that the Replacement Filters are always offered at a good price for a 3-pack.

The replacement filters are functional for one month before becoming contaminated if they are rotated top to bottom in the humidifier. This is acceptable1

These filters have always been better replacements than the general store brand ones. And the new outer layer is a nice plus over the older version.

The only problem I have with these filters is they tend to dry out and I have to take them out and soak them with water. Not frequently, which is good.
