When You Stop Cleaning Your Humidifier, This Is What Happens To Your Body

If you live in an arid climate or use central heating during the winter or air conditioning during the summer, then chances are the air in your home is quite dry. Humidifiers are machines that are designed to add moisture to your home's air by releasing water vapor.

Humidifiers can provide several benefits to your health. When used properly, a humidifier is a great way to hydrate your parched skin, nose, throat, and lips. It can also provide soothing relief when you're coping with cold or flu symptoms. A humidifier can also help reduce asthma and allergy flare-ups. Additionally, sleeping with a humidifier can help prevent snoring, since you're less likely to snore if your airway is moist.

However, if you're not taking the time to clean your humidifier regularly, you may actually end up making your respiratory problems worse or even become sick.

The U.S. Consumer Product Safety Commission (CPSC) warns that dirty room humidifiers can pose serious health risks. Bacteria and fungi commonly grow in the water tanks of portable and console humidifiers and may be released into the air as mist. Inhaling this contaminated mist can lead to respiratory issues ranging from mild, flu-like symptoms to more serious lung infections. People with allergies or asthma may be especially vulnerable, as their symptoms can be worsened by exposure.

Visible signs of contamination include film, scum, or scale inside the tank or on humidifier components. These residues may support the growth of microorganisms. In addition, minerals from the water can accumulate in the tank and be released into the air as fine white dust. This dust may contain tiny particles that can reach the lungs, although the specific health effects depend on the type and concentration of minerals in the water.

To minimize health risks, the CPSC emphasizes regular cleaning and maintenance of humidifiers.

You should start by unplugging the device and disassembling it according to the manufacturer's instructions. Remove and empty both the water tank and the base, and set aside any detachable parts, including the air filter.

To break up any minerals and remove mold and mildew, use white vinegar. Pour undiluted vinegar into the base reservoir and soak the small parts in a separate bowl of vinegar for 30 minutes. Use a soft brush to scrub away any residue before emptying the vinegar. Rinse well. This is important since the next step includes bleach; if vinegar and bleach are mixed, it can give off dangerous chlorine gas. (You also should never mix bleach with ammonia.)

To disinfect the tank, fill it with fresh water and add one teaspoon of bleach. Let this sit for 30 minutes and then empty it.

Rinse all parts under running water. Refill the tank and base with water, agitate, then empty. Repeat until clean. Let all parts air dry completely or dry with a microfiber cloth.

Maintaining the filter is also important. Depending on the indoor environment — such as exposure to smoke, dust, or pet dander — filters should be cleaned or replaced every one to three months. Always follow the manufacturer's guidance and avoid wringing out the filter, which can damage it. Regular cleaning ensures your humidifier runs efficiently and safely.
