This article will compare cool mist humidifiers vs. warm mist humidifiers, including what each type of humidifier is most useful for.
Cool Mist vs. Warm Mist Humidifiers
Cool mist humidifiers and warm mist humidifiers both add moisture to the air which moistens your skin (including your nasal passages) and thin mucus in your sinuses. The National Institutes of Health recommends the use of humidifiers to help relieve congestion from the common cold, flu, and sinus infections. Using a humidifier makes it easier for you to breathe and makes it easier for the mucus to drain.
The key is to keep your humidifier clean and properly maintained so you don’t create an environment that keeps you sick, rather than helping you get better.
There are two main categories of humidifiers: warm mist and cool mist. They essentially do the same thing but in different ways. When comparing cool mist humidifiers vs. warm mist humidifiers, you’ll find that each has pros and cons to consider.
Cool Mist Humidifiers
Cool mist humidifiers are an effective way to humidify your home and relieve congestion, dry throats, and skin. There are three types of cool mist humidifiers.
Impeller: Uses a high-speed rotating disk to release water droplets into the airEvaporative: Transmits moisture into the air using a fan, which blows through an absorbent materialUltrasonic: Creates a cool mist by means of ultrasonic vibrations.
Although cool mist humidifiers do not have the danger of burns or fire hazards, there are concerns with these devices as well. If not properly cared for, cool mist humidifiers can harbor bacteria, mold, and mineral deposits, which they release into the air.
It is very important to properly clean your humidifier according to the manufacturer’s instructions.
Other ways to ensure that you are not putting yourself and your family at risk using a humidifier include:
Changing the water in the holding tank every day Thoroughly cleaning the entire humidifier every three days Using distilled water in the tank rather than mineral-filled tap water
Warm Mist Humidifiers and Steam Vaporizers
If you prefer to use a warm mist humidifier and do not have young children or people in your home that are at high risk for burns from them, you still need to properly care for your humidifier and follow all safety precautions.
The ideal humidity level in your home should be somewhere between 30% to 50%. Humidity levels higher than 60% encourage the growth of bacteria, mildew, mold, and fungi.
Steam vaporizers and warm mist humidifiers both heat water and then release it into the air. Warm mist humidifiers and steam vaporizers are effective ways to relieve congestion but should be used with care. Both have heating elements that can cause burns and can even be a fire hazard.
Follow these guidelines to safely use a warm mist humidifier or steam vaporizer:
Keep them out of the reach of children and away from flammable objects Never place a warm mist humidifier or steam vaporizer on the carpet or another upholstered surface Do not add oils or “vapor rubs” to the humidifier Use distilled water instead of tap water As with cool mist humidifiers, always follow the manufacturer’s instructions for care and use, including keeping it clean
Summary
The best humidifier for you and your home will depend on your needs. When you’re comparing cool mist humidifiers vs. warm mist humidifiers, you’ll find that while they have similar functions, each one offers its own benefits for managing certain health conditions or symptoms. No matter which humidifier you choose, make sure to read the directions and follow the instructions for safe use.
It’s also important to keep in mind that sometimes, a humidifier can make certain allergies worse—for example, a moist environment in your home can contribute to mold growth.
Whichever humidifier you choose, keeping it clean is very important. Mold and other contaminants from a dirty humidifier can make your asthma worse.
