Grainger offers a tabletop or a portable humidifier for a single room, or a furnace humidifier for an entire building. Replace the filter before your dry season begins, as steady use can cause residual mold spores to sprout in your old filter. Get rid of lime scale and germs with a humidifier cleaner—especially in unfiltered ultrasonic humidifiers—and replace the humidifier solenoid valve if you suspect leakage in your furnace unit. Count on Grainger to supply products that will help you keep your humidifier damp and clean.
