Authentic Aprilaire #45 Water Panel Evaporator.?� 2-PACK
Fits models: 400 ONLY
Change every year...twice a year if you have hard water!?� Left over deposits cause the water to "channel" thru the media and not disperse as well as it should, affecting evaporative capacity.
We also sell the scale control inserts, feed tubes w/nozzle, distribution tray, and other items to help your Aprilaire Humidifier run to peak performance.
