How to Select a Humidifier
The Association of Home Appliance Manufacturers (AHAM) tests room humidifiers using uniform methods to verify water output ratings and to allow consumers to compare models accurately. For AHAM’s “Directory of Certified Humidifiers,” visit www.aham.org.

When buying a tabletop humidifier, check to see whether or not it has a humidistat and evaluate the number of speeds or settings it has—some have two or three speeds or a quieter night setting, for example.

It’s also important to examine the types of controls on a console humidifier, which should have a low-water light, automatic humidistat, and air-flow controls. Multi-speed and variable air-flow settings and an automatic shut-off are also helpful. Some models even have a light that goes on when the filter is dirty.

For any type of humidifier that must be filled manually, find out how often it must be refilled when running at full speed.

If you’re looking into a central humidifier, be sure it can be installed relatively easily in relation to your heating system’s configuration. In most cases, maintenance is limited to changing an evaporator pad about once a year; this component should be easy to inspect and access.

Central units are sold at home improvement centers or by heating equipment dealers. If you’re an accomplished do-it-yourselfer, a dealer can help you select the proper size, make sure you have all the necessary components, and give you installation advice. If you haven’t done this type of work before, have the unit professionally installed.

To ensure the lasting and safe performance of a humidifier, be sure to follow the manufacturer’s directions for use and care.
