Aprilaire humidifiers are some of the most consistent whole house humidifiers on the market today. The Aprilaire 400M humidifier is one of the most notable bypass humidifiers, providing humidification for homes as large as 4,000 square feet.

AprilAire humidifiers are remarkable products, and you will find the Aprilaire 400M to be one of their best models with many features.

The Aprilaire 400M house humidifier includes a manual non-digital humidistat control, saddle valve, 24V transformer, and one humidifier water panel.

Our Aprilaire humidifiers come complete with installation instructions and an installation template so you can easily have your new whole house humidifier working in no time. The Aprilaire model 400M humidifier even includes a built-in bypass damper to make for even easier installation and quick changeover from winter to summer settings.
