Types of Humidifiers
Cool mist humidifiers function without a heating element and often use a wick in diffusing mist around your home. The fan is an important feature of this kind and serves to blow air through the filter.
Due to the lack of a heating element, cool mist models are relatively energy-efficient. This lack of element also makes them safer to use around children.
- Reduce room temperature on hot days.
- Includes filters to purify the air.
- Safer for children.
- Ideal during the summer.
- Harder to clean and maintain.
- Noisy at maximum capacity.
The water in a warm mist humidifier is heated up almost to boiling point by a heating element. This heated water is then dispersed around as vapor, which can bring a snuggly and warm feeling around the home when it’s cold.
Since warm mist models need to heat the water first, they use up more energy. Despite this, they’re reported to be a popular choice for many.
- Don’t use fans, so are quieter.
- Raises room temperature.
- Less prone to mold.
- Easy to maintain.
- Well-suited to the winter.
- Consume more electricity.
- Risk to children due to heating elements.
What to Consider Before Acquiring a Humidifier
We know you’re keen to jump to the best whole house humidifiers that we’ve recommended. But, wait a few more moments and take into consideration the following factors before you buy!
Many whole house humidifiers operate by injecting mist — warm or cool — into the environment.
For cold environments, a warm mist whole house humidifier serves the dual purpose of increasing humidity and temperature. In such environments, cool mist may be counterproductive and further reduce the temperature of the home.
On the other hand, in warmer temperatures, a cool mist whole house humidifier will be an ideal choice. It’ll perform the dual functions of reducing the temperature and humidifying your home.
Look out for these key features of whole-house humidifiers:
Environments should be kept at a healthy, constant moisture level. A humidistat is an essential feature that could impact on the health of your families. Maintaining optimal humidity will reduce the risk of suffering from heat strokes, dehydration, and fainting, in some cases (1).
Water Tank Indicator
This feature is key to knowing when your tank is drained or running low.
After procuring a humidifier, maintenance should be a priority. An in-built auto shut off mechanism is essential for this since it turns the unit off when water levels are low.
Many, but not all, humidifiers clean the air with in-built filters. These are handy but aren’t a staple. Filter indicators are ideal for an at-a-glance check if the filters are operating optimally.
Fans are the major cause of the noise produced by humidifiers. This makes warm mist and ultrasonic humidifiers the quietest you’ll find. With these two types, the vapor doesn’t need to be ejected into the atmosphere by a fan, as is the case with cool mist humidifiers.
On the high setting, the noise produced by the fans could be loud enough to disturb your sleep. This is a factor worth considering, especially in houses where there are babies or light sleepers.
How disappointing would it be to find out that your humidifier is good enough for just one room when you have four rooms? Knowing the capacity is vital before making a purchase. Whole-house humidifiers should be able to service a few thousand square feet.
It’s vital to ask about the mist output when trying to figure out the capacity of a humidifier. A higher output means that your spaces will be humidified faster.
Water Tank Size
This feature ties in perfectly with the capacity. Whole-house humidifiers cover a lot of ground. This directly impacts the amount of water they need to function. You wouldn’t want to refill your tank hourly or even daily.
Humidifiers will consume more water when they’re running on their highest settings. The ability to go for longer periods before needing a refill is a great advantage. You should also consider one that has an easily detachable water tank.
