A humidifier helps with dry winter air. But if it's not cleaned, germs can grow in the water and get blown into the air you breathe. Here's the simple routine from the EPA.

Every day, empty the tank, wipe everything dry, and refill it with fresh water.

Use water with low minerals, like distilled water. Tap water can put minerals into the air.

Every third day, unplug it first. Then scrub the tank to remove any scale, film, or buildup.

Follow your humidifier's instructions. If there aren't any, wipe the parts that touch water with three percent hydrogen peroxide. Then rinse the tank well, several times, so no cleaner ends up in the air.

Keep indoor humidity at fifty percent or less. If you see water on windows or walls, lower the setting, move it, or run it less.

Before you store it, make sure every part is completely dry. And clean it again when you take it back out.
