As we know, contaminated mist from unclean humidifiers is more likely to cause infections in people with underlying lung conditions. So, it should come as no surprise that they can also bring on other breathing problems for those dealing with chronic conditions such as asthma. Whole-house humidifiers add humidity to the air and distribute that comforting moisture throughout your entire living space through ductwork. They’re installed directly on an existing HVAC system and are connected to your home’s water line. If you prefer, you can use a bleach solution in place of vinegar for regular weekly cleanings, or you can do a deeper clean monthly with bleach to kill bacteria and get rid of mold. “The key, whatever the type, is to clean and maintain it regularly,” Forté says. “Stagnant water is a magnet for bacteria growth, and you don’t want bacteria spewing back into the air, especially if family members suffer from asthma or allergies.”

For an example of an evaporative humidifier, take a look at our Honeywell Cool Moisture humidifier review. The low-priced, ultrasonic Levoit Classic 300S can humidify a room of up to 505 square feet, which earns it a solid rating in our output test. It’s got a variety of features including automatic shut-off, a digital humidity display more accurate than those of most competitors, and the option to diffuse aromas.
In addition, some homes do not have forced air systems, but instead boiler (hot water) heat which means there’s no HVAC system blower or ductwork in the home. Finally, in some milder climates, a typical HVAC system may not run frequently, which would restrict the operation of an evaporative bypass or fan powered humidifier.
The humidifiers for the bedroom are suitable for spaces smaller than 30 square meters. Alternatively, you can ditch your device entirely and stick to safer methods. Noticed a white film of dust on your furniture and other surfaces since you’ve started using your humidifier?
A humidifier is an essential tool for Floridians seeking to improve their indoor air quality and overall comfort. With various options available, there’s a humidifier to fit every need and budget. “There is no one-step guideline to have a clean humidifier,” Sexton says. “Each unit is different and will require a different maintenance routine.” But you can only reap these big benefits if you’re cleaning your humidifier correctly and consistently. Because when you let your device grow dirty, all kinds of no-good germs can nestle in the nooks and crannies of your unclean machine.
Warm mist vs. cool mist humidifiers
Every product on this page was chosen by a Harper’s BAZAAR editor. When choosing a new humidifier, look at the many options available to select the right one for your needs. Use a scrubbing brush to reach small areas of the machine to ensure the entire device gets cleaned.
Another health risk when operating a humidifier relates to the particles other than water emitted into the air. Unhealthy mineral particles can be released by a humidifier, particularly with cool mist machines. The best way to minimize excessive moisture and decrease dust mites and mold is to monitor the amount of humidity in your home. Maintaining a humidity level between 40 to 50 percent is the sweet spot, per the AAAAI. Not only can microbes like mold and bacteria worsen your breathing symptoms when suspended in the air, but dust mites — which thrive when humidity is high — can also impair your ability to inhale easily. Ultrasonic (or “cool mist”) humidifiers create a cool mist with high-frequency vibration. And in the process, they can aerosolize things like mold and bacteria that you breathe directly into your lungs, according to the Children’s Hospital Colorado.
The LV600S offers some surprisingly robust smart features, too. It will even give you weekly cleaning reminders, if you want them. Plus, the app will tell you what kind of voice commands to use, so you’re not desperately trying to figure out the exact syntax that gets your humidifier to start and stop. A simple, straightforward humidifier with smart-home capabilities and a built-in night-light, the Dreo HM311S is also one of the rare ultrasonics that won’t over-humidify your room. The best humidifier releases gradual, consistent moisture throughout a room, making you feel healthier and more comfortable. And it doesn’t require constant maintenance or leave dank puddles of dew to dapple everything you own. Ultrasonic humidifiers use super-fast vibrations to turn water into vapor.
According to the Consumer Product Safety Commission, you may experience flu-like symptoms or lung infections by running a poorly maintained machine. Flow-through drip-style humidifiers use a specially coated metal or plastic screen that has a small amount of water constantly dripping across it while the furnace is running. Since the water supply is constantly flowing, there is a lower likelihood of mold problems.
