Humidifier Maintenance Tips
Over time, the water reservoir on reservoir-type humidifiers becomes encrusted with calcium and other mineral build-up. It may also begin to harbor bacteria. Use a humidifier cleaner and anti-bacterial solution to clean the reservoir completely at the start of the heating season and again at the end of the season.
You need to clean your humidifier at the end of every season because it builds up scale, rust, and hard water marks as it operates. You can disassemble it for cleaning. Consult your owner's manual to learn the proper technique for disassembling your unit.
Replace the humidifier pad or filter every year.
