In these extremely warm times, there has to be a special knowledge about what it takes to cool an entire room. As strange as it might seem there is actually a science to acquiring the perfect cool humidifier for any particular room. What should be considered is the type of climate the home is in. If it is extremely dry and hot, the harder the humidifier would have to work to cool a room of any significant size. The usual method of determining the size of a room is to measure the length and width and then multiply. That is, a 12×14 foot room has an area of 168 square feet (12 times 14). However, when humidifying a room, the height also needs to be considered. The rating on most humidifiers is given in square feet, but assumes a ceiling height of 8 feet. This means that if a room is higher or lower than 8 feet, someone will have to add or subtract approximately 10% to the size of the space they want to humidify. For example, if there is a 20 x 30 bedroom, that’s 600 square foot. But if the ceiling height is 10 feet, 10% to 15% should be added to that number when looking for a humidifier to properly serve the room. Instead of one with 600 square foot capacity, those with 625 minimum and those designed for up to 650 or 675 square feet should be considered. A humidifier that has a humidity output too large for a room it is in may cause several problems. Excess moisture may form on any cool surface, especially on windows. Mildew, mold, and bacteria may also begin to grow behind furniture or curtains that are close to the walls. Knowing the size of the area that needs to be humidified is hugely important. That being said, 6 litres (1.6 gallon) humidifiers, which is the standard size of most humidifiers created to facilitate rooms, should be enough to deal with spaces up to 500 square feet.
What are the different sizes of humidifiers?
There are three major sizes of humidifiers and they each have a different humidifier rating, as well as square footage usually covered.
- Portable Humidifiers – are the least expensive and best for a single room like a bedroom. These often tabletop humidifiers require the most frequent refilling and are available in ultrasonic cool mist humidifier choices. These are mini size and excellent for travel where exposure to a cool mist in a small area or localized point where someone sleeps or works.
- Room Humidifiers – gives a person a lot of options to choose from that will efficiently humidify a single room or multi-room area of 650-1200 square feet.
- House Humidifiers – models will humidify entire homes as long as there are open doorways. House humidifiers are ideal for areas between 1700 to 2700 square feet. Knowing the size of the room is not the only metric to consider when enquiring about a humidifier for a room.
What are the different types of room humidifiers?
There are five general categories of room humidifiers available: cool mist, ultrasonic, evaporative, warm mist, and vaporizers. Each has attributes that would work for each owner’s personal tastes. These qualities should be assessed before a purchase is made.
- Cool mist humidifiers – These humidifiers emit a cool vapor to add moisture to the air. They utilize a filter that captures water impurities and are easy to clean. They are used during warmer weather and in areas that experience a warmer climate.
- Ultrasonic cool mist humidifiers – these humidifiers rely on high-frequency vibration technology to dispense water droplets throughout the room. The vibration is silent and the moisture is expelled as a fine, cool mist.
- Evaporative cool mist humidifiers – they create an ultra-fine mist that’s released into the room. A fan inside the unit blows over a wick filter, allowing the room air to soak up the moisture and increase the humidity level.
- Ultrasonic Humidifiers – employs a metallic diaphragm that vibrates at high frequencies to create water droplets that are added to the air. They use very little energy and have no operating noise, so they are great to use overnight and in areas where someone wouldn’t want to increase noise.
- Evaporative Humidifiers – An evaporative humidifier operates much like a cool mist evaporator – it does not heat water to create humidity. It is a wick humidifier that uses a fan to circulate humidity.
- Air Washers – help to clean the air while adding humidity to the room. They can remove different pollen and dust particles in the air. For air washers, they only have a cool mist option.
- Warm Mist Humidifiers – heat water to create vapor, which is cooled prior to being released. These systems are less likely to experience bacterial contamination because water is heated. Because the water is boiled before the vapor is released. The harmful particles of bacteria or mold are killed before the mist leaves the device. Warm mist humidifiers work best in small to medium spaces and the boiling process can create mineral deposits, making routine cleaning difficult.
- Vaporizer Humidifiers – A vaporizer may be either warm mist or cool mist. Inhalants can be added, making them a common choice to treat ailments.
In its purest form, a humidifier evaporates water into the air and balances moisture levels in any given space. A portable humidifier is excellent for one room and is the least expensive option. They’re great for people travelling with them as well. Room humidifiers can cover multi rooms or one room, depending on the room’s square footage. These can include air washers, evaporators, and ultrasonic among other options.
