The Aprilaire humidifier line is usually designed to accommodate large areas. Their products have an industrial style than other standard humidifiers for residential use.

It’s unlikely to find small humidifier units (tabletop humidifiers) from this brand. Other than that, Aprilaire also doesn’t offer any ultrasonic machines.

We have the Aprilaire 350 humidifier, which provides coverage of up to 4,500 square feet. It has a self-contained system that connects to your existing ductwork system. Another similar product is the Aprilaire 360, installed through a wall. Both systems require a drain, hot water, and power to function. They also have a control panel that needs to be installed in the home.

Homeowners who want a traditional whole-house system can choose the Aprilaire 400, which works in conjunction with the furnace. It is a large capacity humidifier with 4,000 square feet of coverage.

The Aprilaire 500 Small Bypass Humidifier can also handle up to 3,000 square feet of living spaces. It is designed with a built-in drain to help with mineral build-up and make it easy to use. Another similar humidifier is the Aprilaire 600 (whole-house system), with a larger output of 17 gallons daily.

Aprilaire Steam Humidifiers

Currently, Aprilaire offers two steam humidifiers (models 800 and 865) in their line of products. Both units physically appear the same, but specific differences make the 800 Whole House Steam Humidifier a much better choice.

The standalone unit has a canister-based system, functioning independently from the central HVAC system. It makes for a great humidifier choice for homes with limited, tight spaces. There's also the Aprilaire 801 Whole House Humidifier, a modular system. It gives more accuracy to your home's humidity levels.

You can count on both units to have several unique features than the evaporative system line– such as automatic drain cycles, digital control panel, and drain water tempering.

Automatic Humidity Levels

Humidifiers pump water vapor around the living space if the humidity levels are low. Notably, the Aprilaire 700 automatically functions once it detects low humidity levels and continues until your home becomes comfortable.

Whole House Humidifiers

Aprilaire humidifiers can accommodate your whole house. It’s not just giving off water vapor from one spot. Since it is hooked to the HVAC system, the water vapor comes from each vent.

Some Aprilaire units have a built-in humidistat, allowing you to check the current humidity levels any time of the day. It's also a helpful indicator to determine how well the humidifier unit functions.

Outside Sensor

Aprilaire humidifiers also feature an outside sensor to pick up the humidity levels outdoors and automatically adjust the unit.

The indoor humidity levels can be affected every time you open doors or windows. Some homes are also porous, allowing humidity to escape. Fortunately, some Aprilaire units can adjust swiftly according to different outdoor conditions.


Handy homeowners may opt to install their Aprilaire humidifier by themselves. But if you’re not 100% on what to do, you may be better off hiring a professional to handle the installation project.

The last thing you’d want is to destroy the humidifier in the process or end up hurting yourself. After installation, it should work almost instantly. Expect to see drastic changes in your home’s air quality.


Simply put, Aprilaire humidifiers come at a cost (starting from $200 to $1,000), depending on the type. But, many homeowners consider it an excellent investment due to the convenience and comfort it brings.
