For reference, a HEPA-certified air purifier would bring the number down to virtually zero in less than half an hour. The Winix also had an inferior disk design that required the disks to be inserted only one way; the cover was similarly unidirectional.
Warm-mist humidifiers work by heating water until it turns to steam. And that means these models have the potential to cause burns—from the hot water and steam and from the heating element. Because of that risk, the Mayo Clinic and the American Academy of Pediatrics recommend against their use in homes with children. Warm-mist humidifiers are no better or worse than evaporatives or ultrasonics at humidifying the air.
But they do use a lot more energy. Warm-mist humidifiers do slightly heat the room, meaning you could perhaps turn down the thermostat a pinch. But do warm-mist humidifiers actually offset their energy costs by lowering your heating bill?
John Holecek did a calculation in , and the answer was no. Assume the humidifier sees use for three years for six months each year and dispenses 4 liters of water per day of use. Assume the home is heated with natural gas. By figuring out the energy needed to heat the water from room temperature to near boiling joules , and adding the extra energy needed to vaporize it 2, joules , we know the total energy 2, joules needed per gram of water.
Damp air can feel bad in the winter, and we understand the appeal of warm-mist humidifiers, but producing heat this way is not a good deal. For air washers, which claim to remove particles from the air, we measured airborne-particle concentrations at the beginning of the test and after three hours of running the machines, using a laboratory-quality benchtop optical particle counter that measured particles in the 0.
After running the Venta and the Winix air washers and our top pick, the Honeywell HCM evaporative humidifier, we saw the particle concentrations drop for the Venta and the Honeywell but actually rise for the Winix.
In summary, our take is that air washers and humidifiers can remove some larger particles 0. The idea being that the water will heat up as the radiator runs, gently steaming the pot and producing humidity without the need for all the care and maintenance of an actual humidifier. To test this, one of our writers—who typically dreads turning on the annoying and capricious radiator in his Brooklyn apartment in the winter—tried the method out for a few weeks in February and March of Using the same Lascar data loggers, we tracked the humidity changes over time and compared the fluctuations to both the performance of our budget pick , and to the alternative option of doing nothing at all.
The results were mixed. But that humidification rate was easily eclipsed by our budget pick on its lowest setting, which increased the humidification by double digits. We also tried adding multiple pots to the radiator, as well as a shallow baking pan, hoping that the larger surface area would lead to more evaporated water in the air, but saw no difference in performance.
You can reportedly achieve similar results with a crockpot as well, although the comedian John Hodgman recommends against this. Left uncleaned, humidifiers can quickly become breeding grounds for numerous species of bacteria, amoebas, and fungi that trigger allergies, low-grade fevers, and, in the worst cases, a dangerous inflammation of the lungs called hypersensitivity pneumonitis. This happens so often that it even has a nickname: humidifier lung.
This condition is insidious and comes on sneakily, like a bad chest cold. But one dry night in winter, we turned on our adorable penguin-shaped humidifier. And the next morning, both my now-wife-then-girlfriend and I woke up feeling like we were dying. We got that thing out of the bedroom, I cleaned it, and we cleared up pretty quickly. But we both thought we had caught something pretty serious before she figured it out.
Regardless of which type of humidifier you have, you must clean it regularly to prevent funky stuff from growing in the reservoir and other parts of your machine. The EPA suggests cleaning and disinfecting portable humidifiers every third day; Honeywell, the maker of our top pick, recommends once a week.
A bacteriostatic treatment such as Essick Air or an antimicrobial cleaning cartridge like the fish-shaped Protec can also help to discourage nasty things from going, although they should still be used in conjunction with a regular cleaning.
Typically, water and elbow grease will get the job done, but you may need to use distilled white vinegar every so often to remove mineral deposits limescale. Do not use cleaners or bleach on the wick of an evaporative humidifier, since doing so can damage the material and compromise any built-in antimicrobial treatments. Instead, soak the wick in cold water for 20 minutes and gently swish it back and forth to release often brown, slimy minerals that have built up. To avoid mold growth on the filter, pull out the filter and let it dry when you turn the humidifier off for more than a day, or leave it in and let the fan run with no water until the filter is dry.
This takes about an hour with the Honeywell HCM and causes the machine no damage. Even though ultrasonic humidifiers do not have wicks, many of them have some kind of demineralization cartridge or other treatment that you need to replace every so often. Despite its being an evaporative model, the Venta LW25 has a different maintenance schedule. Note: The additive contains quaternary ammonium cations, or quats, a broad class of disinfectants that have been widely employed for decades.
Quats have been linked to an increased incidence of asthma. But the conditions that elevate that risk—skin contact, high concentrations, the presence of other cleaning agents, and inhalation of aerosolized quats—are unlikely to occur here. In particular, because quats are nonvolatile and the Venta LW25 is an evaporative humidifier, very little vaporization or aerosolization of the additive occurs.
The Vornado UH has the same cylindrical gallon tank, rubber-gasket cap, and humidification controls as its evaporative counterpart.
Sure, the air circulation is great. But that quiet performance is a major appeal of ultrasonic humidifiers; otherwise, you may as well stick with the evaporative version. The whole thing is dishwasher safe, too. However, the tiny button to control the fan can be difficult to find, especially in the dark; the opening on the 2.
Unfortunately, it was discontinued in Our former budget pick, the Levoit LVCH , has been discontinued, too; it was nearly identical to our current budget pick, also from Levoit. It left a glistening film of damp dew on every surface in the rooms we tested it in. The hole in the water tank is also way too small for anyone but a toddler to fit their hand in. This model has a convenient carrying handle and a latch that locks the tank into the base.
Separately, these features are fine, even cool. Together, however, they will conspire to tempt you into carrying the entire humidifier by the handle, which will almost certainly snap off, leaving you with nothing but a wet pile of jagged plastic shards on your floor. But whereas that model feels affordable, the Vicks feels cheap in every sense of the word. On the plus side, it will continue working even after half the pieces snap in half during the cleaning process.
On the minus side, we know from our most recent re-test that half the pieces can easily snap in half during the cleaning process. The Honeywell HCM was the quietest evaporative model we tested on medium—and the absolute loudest on high. Functionally, the HCM comprises little more than a plastic casserole dish with a fan on top. Honeywell was thoughtful enough to add a little drainage hole in the middle of the side to solve this problem.
We found several other potential competitors in early that looked promising at first glance but came from lesser-known brands, received poor grades on Fakespot, or both.
It still works fine, but the Levoit LVHH is superior in every respect, from performance to ease of cleaning to the user interface. The Honeywell HEVB Cool Moisture Tower Humidifier , an evaporative model, has a unique tower-style design, and it performed extremely well in our tests, humidifying the air quickly and holding the humidity steady thanks to its accurate humidistat.
We also like its giant, 1. The tower style does make it visually conspicuous, however, and you can fill the tall tank only under a tub or kitchen faucet, not at most bathroom sinks. To that end, low humidity in your home means the air will feel cooler, causing you to have to turn up the heat more than necessary to be comfortable.
The dry, cool air can cause a lot of static. Is your family getting shocked more lately? A humidifier makes the air less dry and lowers your chance of being shocked at home. Air that is too dry can also affect the finishes and furnishings in your home, particularly those made from wood, causing them to shrink, warp, and crack.
Low humidity could also have a unfavorable effect on paper products, such as photos, posters, and books, resulting in them becoming more brittle. Although you can implement single-room humidifiers to increase the humidity in certain areas of your home, this approach is not the most efficient.

Think about these reasons why a whole home humidifier is worth the investment: Healthy Air, Healthy You A lack of moisture in the air can dry out your nasal passages, leading to irritation of the skin, eyes, nose and mouth and may even exacerbate respiratory illnesses. Stop the Static The dry, cool air can cause a lot of static.
Since the nasopharynx is part of the nasal cavity of our respiratory system, symptoms such as swelling of the lymph nodes or any other obstruction in this area may cause snoring. We can deduce that those who snore from a naso-pharngeal symptom, may find a heated humidifier useful. Though there are benefits to using a humidifier during sleep, excessive use may actually disrupt sleep patterns. For example, high humidity alters the perception of the room temperature of an enclosed room; the higher the humidity, the hotter the room feels to us.
Conversely, if both humidity and heat are elevated, the sweat response will become disrupted, preventing the natural cooling relief of evaporation when we sweat.
This can decrease REM and cause you to stay awake. For babies and young children, dry air could cause health issues. Using a humidifier may help keep the air within acceptable moisture levels. The main benefits of using a humidifier for babies and kids include:. Of course, your child does not need to be sick or have dry skin to possibly benefit from the use of a humidifier.
Moist air in the right amounts may be beneficial for health and could potentially help keep them from getting sick. Read more about a new technology that works in sync with humidifiers to improve your indoor air quality. Depending on where you live, the weather may have an impact on when the air in your home feels dry.
For example, if you live somewhere with high levels of outdoor humidity, you probably run your air conditioner a lot in the summer. Using a humidifier may help counteract this. If you live somewhere with dry air, a humidifier might be good to use year-round. Console humidifiers are large enough to add moisture to an entire house or office, while personal humidifiers are portable and easy to carry. It is essential to keep children safe around humidifiers.
A humidifier can be a great way to add moisture to the air, but there are some risks to consider. Humidifiers turn water into breathable vapor in the air. A dark, humid tank is an environment that fosters germs, but regular cleaning can help to prevent any issues.
Always clean a humidifier thoroughly as directed by the manufacturer. Water should not sit in the humidifier for too long. If the humidifier has a filter, be sure to replace it often. Some humidity in the air can be a good thing, but excessive levels can make breathing difficult and some allergy symptoms worse.
For example, common allergens, including dust mites, mold, and mildew, thrive in damp environments. Humidity levels above 60 percent are too high.
Anyone using a humidifier should also have a humidity meter, or hygrometer, in the room. Some humidifiers have built-in ways to measure humidity, while others require a standalone meter. Many manufacturers recommend using only pure, clean water in their humidifiers. There are a few reasons for this. Unfiltered tap water can contain higher levels of minerals and other particles than purified or distilled water.
Minerals from hard tap water can build up in the machine, causing it to wear down faster than expected. The humidifier can also push these minerals into the air, and a person may inhale them.
The particles may also settle around the room as dust. While using a humidifier can help with dry sinuses, it can also cause harm.
