Best Humidifier For 500 Square Feet

Types of Humidifiers

There are two broad categories of humidifiers: ducted and standalone. Ducted humidifiers are directly connected to the heating and cooling systems of homes.

They use the existing ductwork in homes to dissipate moisture slowly and steadily across the entire house. Installing such humidifiers is a daunting task that requires the skills of a technician.

Standalone humidifiers are the more common type of the two. They may either take the form of room humidifiers that are perfect for humidifying one room at a time or large multi-room humidifiers. Console or multiroom humidifiers are powerful enough to humidify several adjacent rooms at a time.

  • Standalone humidifiers are effective, portable, and easy to use. You plug them into the wall socket and switch them on to humidify the air in your house. There are three types of standalone humidifiers: cool mist, warm mist, and ultrasonic.
  • Cool mist humidifiers disperse moisture that is at room temperature. When you leave your cool mist humidifier running for a while, the room’s ambient temperature falls slightly. Running a cool-mist humidifier is cheap because you do not incur the extra power costs of heating the water.
  • Warm mist humidifiers dissipate moisture that has been heated and then cooled slightly. Warm moist humidifiers are quite costly to run because they have a water heating mechanism. Nevertheless, humidifiers can be of great use in helping you fight off the flu and cold. The heating process kills off all the germs found in the water you use in your humidifier.
  • Ultrasonic humidifiers combine the benefits of cool mist and warm mist humidifiers with special technologies to minimize the noise. Such humidifiers have lower noise levels than either cool mist or warm mist humidifiers. Ultrasonic humidifiers are perfect for bedrooms and children’s rooms because of their low noise levels.

How do you Size a Humidifier for your House?

Standalone humidifiers are designed for either small, mid, or large-sized rooms. Humidifiers designed for small spaces can effectively humidify rooms that measure less than 500 square feet.

Mid-sized humidifiers are ideal for use in small bedrooms or study rooms that measure about 500 square feet. Large humidifiers work well in big living rooms that measure more than 1,000 square feet.

You will hardly get the ideal humidifier for your house if you go with the room size that is indicated by the manufacturer. You should factor in many other things apart from the room size to get the right humidifier.

Notably, you will need a bigger humidifier if your house is poorly insulated. This is because a lot of the moisture ends up lost in the air that flows out of a poorly insulated room.

Things to Consider when Choosing a Humidifier

It may be challenging to get the right humidifier because of the large number of available brands. You can consider the following things when choosing a humidifier.

Ease of Cleaning

The design of your humidifier determines the ease of cleaning it. It takes longer to clean a humidifier with an intricate design than one with a simple design. Also, it may not be easy to disassemble and reassemble the components of some humidifiers. Thus, go for humidifiers that can be quickly cleaned.

The Noise Levels

The noise level of humidifiers varies considerably. Some standalone humidifiers produce enough noise to interrupt light sleepers. If you intend to use your humidifier on the bed side, always go for those brands with very low noise levels. Avoid humidifiers that have very high levels of over 40dB.

Essential Oil Tray

Essential oil tray has become a common feature in modern humidifiers. One can use the tray to include special oils for scenting the room. Alternatively, you can put medicinal additives on the tray to help people who have flu or cold. Go for humidifiers that have the essential oil tray so that you can practice aromatherapy in your home.


Humidifiers that are Wi-Fi-enabled are ordinary nowadays. You can control such humidifiers using an app on your phone. In some cases, one can use voice to adjust the way the humidifier operates.

Check the size and positioning of the controls. Some humidifiers have only one button that you can use with great ease. Others have simple touch-buttons on their surfaces. It is better to get a humidifier that has fewer control buttons that are correctly positioned.


The humidistat helps you to personalize the performance of your humidifier. The humidistat reads the relative humidity of the air in the house and automatically adjusts the humidifier’s performance. It is more comfortable and convenient to use a humidifier with an inbuilt humidistat than one that lacks this feature.

Auto Shut Off

The auto shut off feature in humidifiers prevents accidents by instantly shutting off the device when the water tank is empty. The feature also protects your device from getting damaged in case of water in the tank running low. Check out this feature when choosing a humidifier for your home.

Tips for Maintaining a Humidifier

Humidifiers, like all other devices, need to be maintained and serviced regularly. It is an excellent idea to keep your humidifier in good shape always. You will save a lot of money that would otherwise have been spent to replace a faulty humidifier. Here are a few tips on how to maintain your humidifier.

Carry out deep cleaning once every week

Deep cleaning a humidifier entails dismantling the entire device and cleaning every component separately. You will use a soft brush, water, and detergents to clean every part of your humidifier thoroughly. This procedure is essential to prevent the growth of molds in your humidifier.

Replace the water daily

Often, you will find some water remaining in the water tank of your humidifier. This is common if you have a humidifier with a large water tank or do not let your device run the whole day.

Always remove the water that remains in the water tank of your humidifier. Leaving stagnant water in the humidifier increases the chances of mold and mildew growth. You do not want to have mold growing inside your humidifier because of its damage.

Use Distilled Water

Hard water contains dissolved salts. If you use such water in your humidifier, the salt particles get dispersed with the moisture. The particles may settle on surfaces in your house as a white dust or cause lung irritation when people breathe the air that contains them. Distilled or demineralized water does not contain such salts; thus, use this kind of water in your humidifier.
