Product review (5 stars): This is a genuine Honeywell Brand filter. it is the "new" design and it has no "Blue" on the outside
I have the HCM-6009 humidifier . I used it all during last winter and I think it does an exceled job.

I just got a this new replacement filter. This is a genuine Honeywell Brand filter. it is the "new" design and it has no "Blue" on the outside as the one that came with the humidifier. I just sat it in the humidifier and waited few minutes. You can see the water "clime" on the filter. I flipped it once it got half way up. Few minutes later, it was completely wet. No soaking, no dripping on the floor, no mess.

Honeywell sells this one on their site,  [...]

Strongly recommended
