Day 351 – Cleaning a Humidifier


Humidifiers certainly get a lot of action this time of year. It’s really important to keep them clean to make sure the vapor you are breathing in is clean and healthy. The good news is it’s super easy to clean!


1. Wash off all dirt and dust. Take apart your humidifier according to the manufacturer’s instructions. Look for collections of dirt and dust and wipe off with a damp sponge. Use a mild solution of dishwashing soap and warm water for stubborn, caked-on dirt. Rinse the humidifier and dry it thoroughly with a clean towel.

2. Scrub off any lime deposits. Pour a little white vinegar on a clean scrubbing pad or sponge. Scrub off any stubborn lime scale. Rinse your humidifier and thoroughly dry with a towel.

3. Remove mineral deposits with hydrogen peroxide. Simply pour a little hydrogen peroxide on a clean sponge and wipe off mineral spots. Make sure you thoroughly dry your humidifier. Hydrogen peroxide should also remove any film from inside your humidifier.

4. Use hydrogen peroxide to kill mold. Pour hydrogen peroxide onto a sponge or a scrubbing pad and scrub until every trace of mold is gone. Be sure to put on a face mask before you tackle any mold problems. I didn’t have any mold on mine, but I still rubbed it down with peroxide just to be safe.

5. Use vinegar to clean out your humidifier’s water reservoir. Place your humidifier in the tub or sink, and then pour white vinegar into the reservoir. Let it sit for at least 30 minutes, and then attack the grime and lime with a scrubbing pad, sponge or a soft-bristled cleaning brush. Rinse well with cool water and dry thoroughly. I didn’t fill the whole thing with vinegar. That would have been a whole lot of vinegar! I used about one part vinegar to four parts warm water.

6. Gently remove any filters from your humidifier. Rinse filters with cool water underneath the faucet. If you see mold growing on it, put on a face mask and keep rinsing the mold until it is gone. You never want to use any kind of cleaning solutions on humidifier filters because chemicals can cause permanent damage. Set the clean filter on a towel and let any excess water drip off. Don’t wring out the filter because you could damage it. Put the wet humidifier filters back into their proper spots.

Clean your humidifier often if you use it a lot. Luckily, I’ve only had to pull it out once so far this season for the little man. Hopefully it stays that way!
