Honeywell HAC-504 Series Humidifier Replacement Wicking Filters
I utilize the Honeywell HAC-504 Series Humidifier Replacement Wicking Filters for use on my Honeywell HCM-350 Series Humidifier. Upon installation, a new filter provides an instant, significant increased level of performance from the Humidifier which lasts for months. I highly recommend the utilization of these filters.

I always buy the Honeywell replacement filters. I have found that other brands just don't do the job and mildew and mold grow on them very quickly. The Honeywell filters perform as described and I can usually get 2 to 3 months use out of each filter. I always buy the three pack.

Working as needed
The three pack replacement filters are great to have on hand in the winter months when the humidifier gets more use than other times of the year.

Have never been disappointed with these filters. I have tried ordering filters from other websites to save a little money and there is no comparison in the quality and the others do not last as long or perform as well.

These seem better than ever
I have been using these filters in my Honeywell humidifier for over 2 years. For whatever reason, the most recent filters I received seem to have lasted even longer in my humidifier than the previous ones. I flip my filter every day, and in the winter my humidifier runs nearly 24-7. These filters would last at least 4 weeks.
