Product Overview

The steam canister is responsible for generating the steam that your humidifier then distributes throughout your home. Current runs between 2 electrodes within the canister, heating your water to a boil and creating steam that is distributed through your HVAC system. At the end of a humidifier season, the canister requires replacement. Aprilaire has been there since the beginning by introducing the first whole-home humidifier in 1954. Since then, we've continued to focus on quality design, engineering and manufacturing to deliver Healthy Humidity to every home. Healthy Humidity reduces the incidence and risk of respiratory infections from airborne viruses. It also helps remedy your dry skin, chronic sore throat, frequent nosebleeds and static shock. Additionally, proper humidity levels protect your home's wood furnishings from cracking or splitting while lowering your energy bill.
