Will mold grow inside my humidifier?

Aprilaire evaporative humidifiers are designed to prevent microbial growth. Most importantly, the drain-through technology in the Aprilaire humidifiers leaves no standing water when the humidifier turns off. This leaves all surfaces dry between humidification cycles, meaning there is no moisture for microbial growth.

Is there a warranty for this?

Yes! Aprilaire humidifiers are backed by a 5-year limited warranty on parts. This is from the date of installation, and the system must be installed by a licensed HVAC installer to validate the warranty.

How do I know when my humidifier is operating?

The Aprilaire 500 is designed only to bring the humidity levels up to 45%. If the humidity in your home is higher, the humidifier will not run. If you turn your humidistat from 15% to 45% and the humidifier does not run, this verifies the humidity is higher than 45%. One the humidity level drops, the humidifier should operate any time the furnace is producing head and the indoor relative humidity is less than the set point on your humidistat.

Will a humidifier harm my heating and cooling system or air cleaner?

Aprilaire humidifiers are an evaporative-style humidifier. Unlike misting or atomizing humidifiers, which put water droplets into the air stream, Aprilaire humidifiers use a natural evaporation process to generate humidity. The humidity created is a gas, which simply passes through any component in the heating and cooling system or any air cleaner including an Aprilaire air cleaner with no adverse effects. The humidity created by your Aprilaire humidifier is no different than the humidity present in your home during the summer months.
