Best Humidifier Buying Guide - Consumer Reports (2023)

Heating systems are blamed for dry indoor air, but the real culprit is the cold in winter. And a humidifier can restore the climate balance in a dry room.

Cold air is drier than warm air because it contains less water vapour. When that cold air enters your home through unsealed cracks — or open exterior doors — the resulting dryness can make you feel less comfortable. Among other things, your skin can start to itch, your nails can crumble and even your lips can bleed.

A good humidifier can help prevent or reduce this nuisanceAmerican Academy of Dermatologysay. And he can do even more. According to the Food and Drug Administration, a humidifier that emits cool air -- like most CR test models -- can help reduce swelling in your nasal passages and make it easier to breathe when you have a cold. Higher humidity helps reduce static electricity -- the source of those unsightly carpet bumps. It can even help keep your belongings, such as leather goods and wooden furniture, in good condition.

What is the correct humidity in the room? According to Energy Star, the ideal humidity for your home is between 30 and 50 percent. In colder regions it should be between 30 and 40 percent during the heating season to prevent condensation on the windows. Excessive moisture can promote the growth of mold, bacteria and mitesMayonnaise Clinicsay. You want to find the right balance and a humidifier can help with that.

But with so many models, how do you decide which one?humidifiersuitable for your home? Read on to learn more about the types of humidifiers available, advice on choosing a humidifier for your room size, and factors to consider when making a purchase.

How CR tests humidifiers

At the Consumer Reports Humidifier Lab, we evaluate models based on six criteria: moisture performance, comfort, noise, energy efficiency, humidistat accuracy, and hard water performance.

Our moisture release tests are performed in a room set at 22°C and 30% RH, which is the industry standard for testing humidifiers. Manufacturers usually specify that their humidifiers are designed for a specific room size or area. So we measure the outgoing humidity of the humidifier and calculate how well it humidifies a certain area.

We also evaluate how comfortable it is to use a humidifier to prevent the growth of bacteria. We measure the noise (in decibels) of a humidifier running at full speed. Some are louder than others, and if you're using a humidifier in your bedroom, steer clear of noisy models that can disrupt your sleep.

Testers calculate the amount of energy each model uses to release a gallon of water into the air. Our Humidistat Accuracy Test measures how well each humidifier achieves and maintains a certain humidity level.

Finally, we test the humidification performance of the humidifier with hard water. We do this test because minerals dissolved in hard water can clog the humidifier and reduce moisture output.

Types of humidifiers

Stationary and console (floor standing) humidifiers are divided into warm, cool, or dual mist models that can produce both warm and cool mist. In our tests, humidifier prices ranged from just under $20 to $800.

Consumer Reports is not currently testing whole-house humidifiers. "However, if your home is heated with a forced air system, this is a great option," says Misha Kollontai, who conducts humidifier testing at CR. Appliances throughout the house have access to the oven's air ducts and are connected to the water supply. They usually require professional assembly.

"These systems are designed to keep all the heated air in your home at a comfortable humidity level," says Kollontai. "They require much less maintenance than portable devices."

Cool mist humidifier

Most humidifiers sold are cool mists. If you have a cold, according to the Food and Drug Administration, a cold mist humidifier can help reduce swelling in the nasal passages and make breathing easier.

There are two types of cold mist humidifiers in our review: evaporative and ultrasonic. Evaporative models use a fan to push air through the wet wick, and the air cools by absorbing moisture from the wick. Replacing the fuses usually costs between $10 and $20, depending on the model. Ultrasonic humidifiers use an atomizer, a small vibrating membrane, to create a cool mist. Since there is no fan, ultrasonic models are usually quieter. Most of the humidifiers in the CR tests are cool or dual mist humidifiers, giving you the choice between cool or warm mist. Prices range from $19 to $800.

Warm mist humidifier

Warm mist humidifiers, also known as vaporizers, are usually the least expensive option. They use a heating element to bring the water to a boil and produce a warm mist, which consumes more energy than cold mist models. But as the temperature drops, you may want a warm mist to hover around your home, not a cool one. However, warm mist models can cause nasal passages to swell and make breathing difficult. Therefore, according to the FDA, they should not be used to relieve cold symptoms.

CR does not recommend using the Warm Mist Humidifier near children as the humidifier tank contains hot water which could cause burns if the humidifier tips over or leaks. The prices of the models we tested range from about $15 to nearly $300.

The best humidifier for the size of the room

To determine the size of humidifier you need, first measure the area of ​​the room. Humidifiers in ourThe sentenceare organized by the size of the room or area they are intended for, ranging from personal humidifiers that can humidify up to 25 square feet to consoles measuring 1,000 square feet or more.

For small to medium-sized rooms, stationary humidifiers are the most affordable option, but their small tanks require frequent refilling. Console models are best suited for large rooms, as they generate a lot of humid air. They also have larger water tanks, so fewer refills are required. However, due to their size and weight, they can be difficult to maneuver when fully loaded.
