  • AprilAire Model 400 Humidifier

The AprilAire 4406 Humidifier Float Valve Assembly floats in the scale control insert/float chamber to control the water supply. There are two float assemblies required: one assembly on the right hand for function and one assembly on the left hand for safety backup. When the water evaporates and the float reaches the bottom, the electronic switch is activated and the water supply turns on. When the water level is high, the right hand float turns the water supply off. The AprilAire brand is also identified by the following spelling variations: April Air, April Aire or Aprilair.

It keeps the air very clean and doesn't have to be replaced often.

I like the MERV 13 filter kit for my Air cleaner system. Firs and works perfectly.

High quality filters and UV bulbs--prefect for the Lennox furnace/AC unit. Highly recommended.

I buy the X8797 from filtersfast because it saves me money! Kit was received in excellent condition. Very easy to install. Why pay your local AC guy, who marks up the price of the kit plus charges for labor, when you can save money and do it yourself. Thanks filtersfast!
