Best Humidifier

Humidifiers are designed to help maintain an optimal humidity level in your home. When looking for a humidifier, take into consideration the size of the humidifier. Will it be large enough for the entire house, will it humidify only one room, or do you need something permanently installed? Where will you use the humidifier, do you need warm- or cool-mist, or ultrasonic humidification? This list of humidifiers include smaller, portable units for single rooms to larger, permanently installed additions to your existing heating system. We’ve also included a humidifier buyers guide below which provides detailed information to help you in your search.

Essick Air MA1201 Whole-House Humidifier

A digital humidistat allows the Essick Air MA1201 to automatically maintain your chosen humidity level for a space of up to 2,500 square feet in size. This whole house console humidifier uses evaporative technology to add moisture to the air which can help reduce the need to run a heater as often, reduce dry air discomfort, and help preserve wooden furniture and floors.

The MA1201 is easy to use and easy to clean, with castors allowing it to be moved from room to room as needed. The water reservoir holds 3.9 gallons of water, and the unit will automatically shut off when out of water. This humidifier will also display a message when the filter needs to be replaced. The MA1201 is reasonably quiet for what it is and the humidifier overall does not have an invasive presence in a space.

The water tank is removable and includes a built-in handle to make it easy to fill, while the humidifier itself has castors for mobility and an on/off indicator light. Maintenance on this console humidifier can be a fairly large task, but isn’t needed too often. Overall, despite the Lasko Model 1128 being prone to getting loud when on its highest setting, this whole house console humidifier provides solid performance for a large space.

Adjustable humidity and three moisture settings allow you to set the humidity to your desired level, and special filters help to trap allergens and germs before they can be dispersed into the air.

This humidifier is capable of an impressive 12 gallons of output per day, adding lots of moisture to the air in your home. The digital touch screen controls are easy to use, and the humidifier automatically shuts off when the desired humidity level is reached or when te unit is out of water.

Evaporative technology makes the Model 400 more efficient, with gravity pulling water down through the unit, and wicking action drawing it back up to provide humidity to the system. This also eliminates the need for a floor drain. This humidifier is rated to provide .70 gallons of humidity per hour to up to a 4,000 square foot house.

Aprilaire Automatic Whole-House Bypass Humidifier with Digital Control Model 600

Although this model can also be purchased with everything needed for fully automatic operation, we've chosen to include the Aprilaire Model 600 without that capability for those who would rather pay less and have manual controls. The Model 600M lacks the outdoor sensor of its automatic counterparts with some users believing the outdoor sensor doesn't do a good enough job of contributing to effective regulation of humidity levels (and end up using the unit in manual mode).

By going with the manual control setup, you can save money not only on the initial cost of the unit, but the added cost of installation due to more components, and the cost of potential  malfunctions as well. Beyond this, the Model 600 performs much the same as Aprilaire's other excellent humidifiers. It’s rated to provide .70 gallons of humidity per hour to a home of up to 4,000 square feet in size, and uses evaporative technology to conserve water.

Buyer's Guide

Finding the Best Humidifier: Buyer’s Guide

A good humidifier needs to serve the single purpose adding moisture to the air. Ideal indoor humidity rests between 30 and 50 percent and this level can drop drastically during winter. Reduced humidity can aggravate allergies, cause static electricity buildup, and complicate symptoms such as itchy eyes, sore throat, and dried out skin. Conversely, humidity levels over 55 percent can promote the growth of mold and bacteria. Because of this, humidifiers which consistently and accurately maintain humidity levels within the ideal range are the best to have.

When looking for a humidifier, the first thing to do is identify your needs. Humidifiers are available in very small sizes, being designed for occasional use to add moisture and comfort to the air in a small space. They can also come in large console models to humidify an entire house, or can be installed to work with your furnace. Each type comes with its own purchase price and maintenance cost considerations.

A more expensive humidifier isn't always better. You can get an excellent basic model for a budget-friendly price. However, spending typically yields added features such as a humidistat which allows for setting and monitoring the humidity level within the desired 30 to 50 percent range. Many humidifiers also feature playful, colorful designs and while this doesn't equal less performance, you’ll always want to prioritize substance over style.

Extremely low-cost and basic humidifiers usually work for short-term use, such as relieving the symptoms of a nasty cold. For long term solutions there are numerous options depending on the size of the space where added humidity is needed. For example, individuals in warmer climates might prefer a cool mist humidifier due to their tendency to make the air feel cooler or warmer.

If you have children, you might want to consider spending more on a humidifier that has multiple built-in safety features and even perhaps a playful design. If you have persistent problems with dry air throughout your house, a whole house console humidifier or a furnace humidifier might be worth the investment.

Humidifier Types

Cool Mist Humidifiers
These models use a fan to distribute moist air throughout the room. These humidifiers tend to offer low power consumption and better safety since there's no hot water to cause burns if it’s knocked over. However the fan can produce higher levels of noise.

Warm Mist Humidifiers
Sometimes called vaporizers, these units boil water and emit steam vapor to humidify a space. They’re typically quiet except for the soft bubbling noise of boiling water. These humidifiers come with higher power consumption levels and the risk of burns if a child or pet accidentally knocks one over. The best models will have auto shut-off features for safety in case they run out of water or get knocked on their side.

Dual Mist Humidifiers
These combine the characteristics of warm mist humidifiers and cool mist humidifiers into a single appliance. These units tend to cost more but some people prefer the convenience of having a choice.

Ultrasonic Humidifiers
Typically the quietest humidifiers you can purchase, ultrasonic models utilize a vibrating metal diaphragm to create tiny water droplets making them ideal for bedroom use. Though ultrasonic humidifiers are usually cool mist, higher-end models provide a warm mist option. Although they use very little power, these humidifiers may create “white dust”, a fine powder caused by minerals in water. This can usually be solved by using an optional demineralization cartridge or simply using distilled water.

If you're looking for a more permanent, long-term solution, whole house console humidifiers and furnace humidifiers might be a good option for you:

Whole House Console Humidifiers
Similar to smaller, more affordable humidifiers commonly found in stores, but these take up much more space, have large capacity water tanks, and effectively humidify very large areas. They also tend to require minimal maintenance which helps make up for their higher purchase price. Because of their size and the amount of noise their powerful fans can produce, carefully consider where you’d install the unit.

Furnace Humidifiers
These units are used to add humidity to your entire house in conjunction with your existing furnace system. These humidifiers are mainly evaporative-bypass units which work by blowing air over a wet wick and distributing the air using your furnace. These units tend to be quiet and require very little maintenance while offering the convenience of serving the entire house using an existing system. However, they usually require professional installation and can be quite pricey to purchase.

Extra Features

Water Tank Size/Ease of Refill
These variables might seem insignificant, but they’ll determine how long you can go in between refills. A humidifier can become a hassle if the tank isn't large enough to last through the night.

Timer
A good feature to have, although the most important thing is intuitive controls and ease of use.

Power Consumption

With smaller units intended for occasional use, a humidifiers power consumption isn't usually too big of a concern. However, regular users might find energy costs can add up over time.

Safety Features

Safety is important, especially with warm mist humidifiers. Look for models with auto shut-off for added security, and avoid having to constantly check if the unit has enough water. Features such as UV technology help keep the water tank germ-free but regular tank cleaning is important to prevent build up of potentially harmful bacteria.
