And why your skin needs one this winter.

Cooler weather often calls for turning on the heat which, while cozy, can also lead to dry air (and raspy morning throat). Luckily, a humidifier can help promote hydrated skin and healthy sinuses- unless, that is, you haven't cleaned it since last winter. To help you avoid dirty vents spewing germs around your home, we turned to the cleaning experts for the care tips for your humidifier so you can breath easier and say so long to dry skin all winter long.


For the deepest clean, you'll want to disassemble your your humidifier to ensure all parts are cleaned out thoroughly. "Use the instruction manual it came with for step-by-step instructions, as each machine will differ slightly," says Melissa Maker, YouTube host and author of "Clean My Space". If you're using your humidifier everyday, a deep clean should take place at least once a week; for larger humidifiers (more than 5 gallons), once every two weeks should suffice.


Unless you've got seriously bad build-up, skip any harsh cleaning products as Maker reminds us: "[This] can damage the material and also absorb into it, so that when you use it again you could be breathing the product in." Instead, she suggests eliminating [build-up] with a solution of equal parts water and white vinegar: "Add it to the water tank up to the maximum fill line and let sit for 10 minutes. Then scrub and rinse."

You can also create a mixture of tea tree oil (about 10 drops) and a cup of water to scrub the machine with. "But be aware that you may smell tea tree oil when you run your humidifier over the next few uses." (In other words, if this fragrance isn't your happy place, perhaps skip it.)


The water tank is also a magnet for mold and mildew; if you notice either in yours, Maker says to clean it with a bleach-free, anti-mold spray, such as Concrobium ($13, "Make sure to rinse all the pieces well with fresh water before reassembling." To limit regrowth, Sarah Drake, seasonal humidifiers brand manager at Honeywell Humidifiers, recommends putting in an antimicrobial cleaning ball, like Protec ($10 for 2,, in the tank. "It fits in almost all humidifiers-just drop it in the water tank!" Be sure to replace the ball every 30 days or so.


Many models use a disposable kind to wick moisture or absorb minerals. "Replace it when it gets hard and crusty, it starts to give off an odor, or moisture output decreases," says Drake.


The best maintenance rule of thumb? "Empty humidifiers in the morning and let them dry out before refilling for the night," says Becky Rapinchuk, author of "Simply Clean" and the cleaning and homekeeping expert behind She also recommends using distilled or filtered water to help prevent build-up. In between emptying and refilling, Drake suggests wiping down the humidifier with a clean cloth. "This helps to prevent scale and bacteria from building up."
