Good quality for a must have!
My Honeywell HAC-504 series humidifier is a necessity in my home. It helps us when we sleep to get moisture in our bedroom. It was time to change the filter. What better place to order them from. Honeywell! Reasonable price!

still the best
The packaging has changed over the years, and unfortunately they cost more than they used to, but these filters are still better than all the one-offs I've tried. They last longer, without disintegrating.

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.
