If you ever deal with sinus issues or suffer the effects of dryness in the colder months, adding a humidifier to your home can bring a lot of relief and help you stay healthy throughout the winter (or any other seasons, if you live in a low humidity climate or put the heater on blast). Ideally, most homes should have a 30 to 50% humidity level. If you do decide to monitor humidity levels in your home, it’s important to know how to clean a humidifier to keep your home and air quality clean.
While humidifiers have plenty of benefits like soothing your sinuses, moisturizing your skin, and reducing snoring while improving sleep quality, cleaning a humidifier can be a headache. This is a device that’s frequently holding water, so calcium build-up is inevitable. Additionally, all the nooks and crannies in humidifiers can turn them into a breeding ground for bacteria and dirt, which you’ll be inhaling at some point. Here’s our ultimate guide on how to clean a humidifier, as well as our top picks on hassle-free, easy-to-clean humidifiers.
How To Clean a Humidifier
1. Disassemble your humidifier
These machines have a lot of working parts, and you can’t exactly throw the thing in the dishwasher. First, unplug the humidifier. Then, take out the water tank and empty any leftover water before you unlatch and unlock all components that can be removed. Filters should only be cleaned with a quick rinse and not with cleaning chemicals.
2. Clean with a solution of your choice
At this point, you can pick your cleansing solution. While there are humidifier cleaning tablets and pre-formulated solutions, the cheapest and most natural way to clean your humidifier is by using distilled white vinegar, or apple cider vinegar. Here are some tips for how to clean a humidifier with vinegar: Pour it into the base and let it soak for about half an hour. Wipe down smaller parts with a paper towel or cloth dipped in the vinegar, using a brush on stubborn stops. To dislodge an excess of grime, add a few tablespoons of rice and cold water to slough off the gross stuff.
As we mentioned, there are plenty of store-bought products that you can use for disinfecting any leftover bacteria after you’ve wiped off the dirt. You can blend a gallon of water with a teaspoon of bleach, hydrogen peroxide or an all natural-solution, swirling around the tank and letting it sit for half an hour.
4. Rinse and put it back together
Carefully dry all the parts with a paper towel or microfiber cloth before your put your humidifier back together. When you refill after your deep clean, consider using distilled water, which can help prevent the mineral buildup caused by tap water. Voila! That’s all when it comes to how to clean a humidifier.

How To Choose a Humidifier That’s Easy To Clean
Although most humidifiers require cleaning, the nature of their design can make a big difference to users over time. Search for a unit with:
- A large entrance at the top side for easy filling and cleaning
- Minimal nooks and crannies for simpler maintenance
- Opt for a cool mist or ultrasonic model, which reduce bacteria
1. Use apple cider vinegar as a less stinky alternative

They can be used for laundry and other multipurpose cleaning purposes, like disinfecting your humidifier. A safer way to keep bleach in the household that also has a longer shelf life.

4. Get a demineralization cartridge

They also remove the odor that some humidifiers can develop after heavy use. Every cartridge provides up to 30 tank fills, depending on how hard the water is in your area.
