Common questions

Clear answers before you call

What humidity should I set in winter?

About 30 to 40% for most homes, lower on very cold nights to avoid condensation.

Can I add a humidifier to a boiler system?

Not a duct-mounted one. Radiator-heated homes use standalone or steam units with a dedicated distribution method.

Does a humidifier need maintenance?

Yes. Replace the pad or clean the steam canister yearly, and check drains.
