How to Clean a Humidifier (EPA Routine)

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.

1. Every Day

Every Day

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

2. Use Low-Mineral Water

Use Low-Mineral Water

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

3. Every Third Day: Clean It

Every Third Day: Clean It

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

4. Disinfect + Rinse

Disinfect + Rinse

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.

5. Don'T Overdo It

Don'T Overdo It

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.

6. Putting It Away

Putting It Away

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