Warm Mist vs. Cool Mist Humidifier
We carry all types of humidifiers to suit different preferences at Allergy Be Gone. Whether you choose Warm Mist or Cool Mist is a matter of taste. Both effectively raise the humidity level and will make your home more comfortable. Here is a comparison between these two types of humidifiers.
Cool Mist Humidifiers
Cool Mist Humidifiers use a filter to trap minerals and impurities and then a cool invisible mist evaporates into the air. They include evaporative humidifiers, impeller humidifiers, and ultrasonic humidifiers.
- Pros:
- Easy to clean
- More effective in larger areas
- Cool mist is easier to breathe
- Cool mist is more comfortable in warmer climates
- Airwashers (such as the Air-O-Swiss models) produce a cool mist that reduces dust and particles in the air
- Easier to clean
- Cons:
- Slightly noisier than warm mist units due to the fan noise (except for ultrasonic models)
- Cool mist can feel slightly cool and clammy at certain room temperatures
- Wicks in evaporative humidifiers can get dirty or develop mold. Algae can grow in the tank if water is left standing in it for too long
Warm Mist Humidifiers
Warm Mist Humidifiers produce warm, soothing mist that you can see and feel. They include steam humidifiers and vaporizers.
- Pros:
- Great for treating cold and flu
- Many models include a medicine cup to disperse respiratory medicines, inhalants, or essential oils
- More quiet than most cool mist units (although they can produce a boiling noise)
- Warm mist is more comfortable in cooler climates and during the winter
- Cleaner mist than in cool mist humidifiers
- Cons:
- Require frequent cleaning and are more difficult to clean than cold mist humidifiers, since boiling water leaves mineral deposits behind
- Cover smaller area than cool mist humidifiers
- Can leave the room feeling a bit muggy
- Hot steam can be dangerous - keep out of reach of the children
Summary
Much of the choice between cool mist and warm mist humidifiers comes down to personal preference and location. Before buying, think about what type of climate you live in, where your home is situated, how air circulates in your home, and what kind of personal environment you wish to create for yourself. Some allergists and other doctors might also prescribe a certain type of humidifier for allergies, asthma, or sinus problems.
