Using a humidifier in the wintertime can be a great fix for the health, comfort, and interior problems caused by dry air. By dispersing an invisible mist of moisture throughout a space, these appliances help relieve dry and itchy skin, moisturize parched respiratory passages, and reduce the amount of static electricity in your indoor environment.
However, a humidifier can quickly become a health hazard when not properly cared for and maintained.
Humidifier Cleaning Routine
If you use your humidifier frequently, cleaning it every three days is essential; otherwise, a weekly cleaning will suffice. Check your owner's manual for any other information on cleaning, but here are a few steps to get the job done:
- Turn off the humidifier and unplug it. Don't submerge any electronic components.
- Empty any standing water from the reservoir. Wipe down with a paper towel, especially if it's been a while since you've cleaned it, or use a soft-bristled brush and mild cleanser.
- Fill the tank and base (if possible) with clean, warm water and a teaspoon of white distilled vinegar (one teaspoon of vinegar per 32 ounces of water). Let everything sit for 30 minutes.
- Wipe down the exterior with a damp cloth.
- Rinse with warm water, and let each piece dry thoroughly before reassembly.
If your humidifier needs a deep clean, then use bleach or hydrogen peroxide instead of vinegar with a ratio of one teaspoon of bleach per gallon of water. Some brands also make special descaling solutions for a scent-free alternative to household cleaners.
Some humidifiers may also include a filter or hydro cell, which needs to be replaced regularly. When cleaning your humidifier, remove the filter or wick every time and allow it to air dry. Consult your owner's manual for more details.
Why Do You Need to Maintain a Humidifier?
All humidifiers, regardless of their type, carry a risk of bacteria and mold growth. This may be the result of two things:
- Lack of Cleaning: As with anything when dealing with water, failing to clean the humidifier's components and change the water regularly can result in mold and bacteria growth, which multiply inside the humidifier and are released into the air you breathe.
- Tap Water: Filling your humidifier with mineral-rich tap water can produce “white dust” that gathers inside and on surrounding surfaces. Additionally, the high mineral content of tap water can cause a dirty film to build up inside the water reservoir. The mineral film and dust mix with the moisturized air and become part of the indoor air.
Tips for Properly Maintaining Your Humidifier
To reduce your risk of developing these conditions when using your humidifier, study how to maintain it properly. Remember these tips:
- Change the water in your humidifier daily. Don't let water sit inside the base or the tank, as stagnant water is a breeding ground for mold spores, allergens, and bacteria.
- Use distilled or demineralized water to fill your humidifier. Distilled or demineralized water has less mineral content than regular tap water. When used, these water types make your humidifier less likely to expel white mineral dust into your indoor air – and less likely for that dust to invade your lungs.
- Check for signs of build-up. Keep an eye out for signs of moisture build-up around your humidifier; you may need to move it away from curtains, drapes, or other materials that easily absorb moisture.
- Use a natural cleaning solution to clean your humidifier. This especially benefits allergy- and asthma sufferers and those with multiple chemical sensitivities. Use natural white vinegar, a disinfectant and deodorizer, to eliminate mineral buildup and disinfect surfaces.
