EFP Humidifier Filter Replacements for Duracraft AC-809, DH803, AC-815 Models | Includes 2 Aftermarket Filters

Fit humidifier perfectly

A product I’ve had before and they perform well.

Perfect fiit

They fit well and they do the job of filtering.

Everything works as expected

These are good for the money. I have to cut mine down because I have a very old humidifier and find it is easier to cut wet. Just watch what you are doing because it will cut you.

Fit my Aprilaire 600 Series good, but when I went to change after 1 season I saw that it considerably deteriorated and pretty much crumbled in my hands, unlike the aftermarket ones I had before it.

The old filter looked ok, but it was evident it was not working properly. With the new filter installed the device was putting about twice as much moisture in the air.
