Ultrasonic Vs. Regular Humidifiers

Ultrasonic Humidifier Defined

• Ultrasonic humidifiers utilize a metal diaphragm that vibrates at ultrasonic frequencies to produce a cool mist. They make virtually no noise and won't disturb you while they're operating.

Regular Humidifier Defined

• Regular humidifiers are known as vaporizers or steam humidifiers. They are the most common and economical type of humidifier. A steam humidifier boils water in the unit to create steam that is released into the air. Regular humidifiers also allow you to substitute a medical inhalant for the water to soothe asthma symptoms.

Considerations

• Ultrasonic humidifiers are prone to spread bacteria if not properly cared for. If the water in the unit becomes stagnant, the ultrasonic humidifier cannot distinguish this and will spray the contaminated water into your room. If you don't use distilled water and your tap water is mineral-rich, the unit will spray the minerals into your room as well. The minerals turn into dust and reduce your air quality. Steam humidifiers can cause burns if not kept away from children or pets.

Benefits

• Ultrasonic humidifiers consume the least amount of energy, and many models now offer methods for killing bacteria present in the water via ultraviolet light. Many models also offer a demineralization cartridge to filter the water, greatly reducing dust. Steam humidifiers won't ever dispense bacteria or minerals into the air because the water is boiled before being expelled. Minerals are too heavy to remain in the vapor and bacteria are killed during boiling.

Function

• Low humidity in your home can result in dry skin, chapped lips, a sore throat and sinus trouble. Lack of moisture in the air also results in cracks in walls, parched houseplants, peeling wallpaper and dried-out wood that shrinks and cracks. Static electricity is more prevalent in dry air and the temperature can feel 5 degrees F cooler than it actually is. Ultrasonic and regular humidifiers work to re-establish the equilibrium so you won't have to turn on your heat as much.
