Aprilaire 35

Keep your evaporative humidifier operating effectively with the AprilAire 35 Replacement Water Panel Humidifier Filter. The water panel slides into the scale control insert and water distribution tray, where it begins to absorb water. The aluminum mesh features a porous ceramic-type coating for enhanced absorption. Once saturated, the humidifier moves air through the filter which adds humidity to the room. Humidifiers are great for preventing mold and fungus growth, and alleviating cold weather symptoms such as cracked lips, bloody noses, sinus irritation, coughing and more. Keep cold weather symptoms at bay and replace your filter today!

This is the OEM filter which I could not find in any local stores. The original filter is thicker (more effective) than the knockoffs I was able to find.

Great filter

Better prices than my local HVAC shop and never and issue with the product. I’d suggest changing shipping carriers from FedEx as they delayed delivery numerous times and then left the product out in the open in the rain versus under a covered porch.

Right filter

Great product, environmentally green. Damage is pretty severe, it might fix itself. It's just knowing which one you should get. Luckily my Sr v628 pcv cartridge for the Hot/cold water cross over, has softner and sediment remover.
