7 Best Humidifier For Large Room in 2023

Humidity is an important physical factor that is present almost everywhere. This physical commodity affects humans’ overall health and comfort in various seasons. Since humidity is dependent on various factors, its presence might not be constant every time. Lower levels of humidity result in dry air and, thereby, nasal or respiratory issues. To combat these issues, humidifiers are used.

Humidifiers increase the humidity level in the surrounding air by adding moisture. These devices are beneficial for human health, irrespective of the season. Depending on the size of a room, some humidifiers are tuned for efficient output. While selecting a humidifier for a large room, certain factors are considered to get the desired output and coverage from the device.

  • Water tank capacity: Water is stored in a humidifier which helps in adding the required moisture to the air. The water storage tank must be large enough to hold a good amount of water. The tank capacity ultimately governs other factors like the runtime of the humidifier. Humidifiers usually come with a tank of 3 to 6 liters capacity.
  • Room size (sq. ft): The size of the room plays a vital role in the performance of a humidifier. For a small-size room, the humidifier will have to work less to cover the whole space. Similarly, the humidifier has to work more for a larger room to cover each corner. Choosing a humidifier with more capacity than the actual room size is advised. The humidifiers for a large room can easily cover 500 to 700 sq. ft space.
  • Run time: The runtime of a humidifier is the measure of its operation before needing a refill. The runtime of a humidifier depends on various factors like the tank capacity, type of setting, etc. Various brands offer the runtime of a humidifier based on a certain setting. On average, a humidifier runs over 24 to 48 hours before needing a refill.

With the help of these factors, a user can choose a suitable humidifier. Various brands offer a wide range of humidifiers with certain configurations. To avoid confusion for the users, we have compiled a list of the best humidifiers for large rooms. A “Buying Guide” is also provided, which further explains the importance of a few humidifier governing factors.

Before moving on, we should be aware of certain parameters that affect a humidifier’s performance and selection process.

White selecting a humidifier for a large room, the tank capacity is given importance. To cover a larger space, a continuous supply of water is needed. Hence, a large amount of water must be readily available for the humidifier to continue its operations. The humidifiers are fitted with larger water tanks, which helps increase the runtime. A larger tank doesn’t need frequent refills. The humidifiers for large rooms have a capacity of 3 to 6 liters which ultimately gives a runtime of 24 to 48 hours. Increasing tank capacity also increases the size and weight of a humidifier, which affects its portability.

2. Room Size (sq. ft)

Power, humidity settings, and coverage of humidifiers are designed by keeping a certain room size in mind. These factors ensure that a large room will humidify in less time while maintaining constant humidity. To ensure efficient coverage, a humidifier with more coverage areas is chosen. For example, for a room of 600 sq. ft size, a humidifier with a capacity of covering 700 to 800 sq. ft is chosen. This ensures efficient coverage even with unavoidable leakage of moisture. On average, humidifiers are suitable for large rooms of 500 to 700 sq. ft size.

3. Run Time

The runtime of a humidifier gives the user an idea of how long it can operate on a single refill. The theoretical runtime is calculated by running the humidifier in a controlled environment. The actual runtime, however varies due to factors like humidification setting, size of the room, tank capacity, etc. When set for higher humidification, the humidifiers will eventually run for less time. The specified runtime on humidifiers is usually recorded at the lowest setting. Some humidifiers also have automatic cut-off features to increase the runtime further. On average, a humidifier for a large room easily runs for 24 to 48 hours.

4. Type Of Humidifier

There are various humidifiers with different working principles, pros, and cons. The most popular humidifiers are ultrasonic, evaporative, and steam units. Ultrasonic humidifiers are the most recent type of humidifier. They use very high-frequency vibrations to create tiny water droplets. These units are used for their silent operations. Evaporative humidifiers are one of the most common types used for large rooms. They use a wet wick and blowing fan to circulate moisture. These units are effective but louder due to the blower fan. The steam humidifiers release steam by boiling water from the tank. These units are also quiet, but the hot steam poses a risk of burns.

5. Maintenance

Humidifiers are in contact with moisture for the majority of their operations. This condition is favorable for the build-up of bacteria and molds on parts like blowing fans, etc. The metallic surfaces of the modifier and water tanks also experience a build-up of minerals that needs cleaning. A humidifier must offer easy cleaning with a lower maintenance cycle. Some units also use filters that can be either cleaned or replaced within given time intervals. A facility to replace the water is provided to prevent the circulation of stagnant water. Users are provided with instruction manuals that aid in properly maintaining the humidifier.

6. Type Of Control

To access various functions of humidifiers, different types of controls are provided. The most common type of control is manual control. Various control knobs, buttons, and switches are provided on the humidifiers, which control the humidity level and other functions. For the touch control units, a touch-enabled screen is provided with a functions menu. To offer remote access to the humidifier’s functions, a dedicated remote controller is also offered by some brands. Wireless control is also achieved with the help of a smartphone app. Latest technologies like voice control have made it easy to control humidifiers via the user’s voice.

7. Warranty

Humidifiers for large rooms often come with a warranty to guarantee quality to the user. Since humidifiers are electrical units and are in contact with moisture, they are bound to get damaged. Brands thereby offer a limited warranty period to assure users of free repairs or replacement of damaged parts. Most humidifiers come with a minimum of a 1-year warranty period. Users can also opt out of extended warranty schemes provided by the brand, for peace of mind. Warranty on parts like motors, fans, etc, is also provided by the brands.
