Cool Mist Benefits

Breathe Comfortably

Optimal humidity reduces irritation from dryness and helps to support your body’s natural defenses and immune system during the cold and flu season.

Rejuvenate Your Skin

Renew cracked lips and flaky skin for a fresh, comfortable feeling.

Sleep Peacefully

Relax with tranquil mist that flows through your space. Dry nasal passages and airways can interrupt a good night’s sleep.

Protect Your Home and Furniture

Dry air pulls moisture from the wood in your home and furnishings, This can lead to cracks in wood or doors that do not close properly.

Reduce Static Electricity

No one likes the feeling of static electricity in their clothing or hair. Proper humidity levels help to alleviate wintertime static electricity.

Feeling revitalized and refreshed after a long day at work

The Cool Mist Difference

Air Oasis has been dedicated to improving indoor air quality for 18 years. With our Cool Mist Humidifier you can achieve optimal humidity for you and your home.

Ultrasonic Misting Cool mist humidifiers add moisture to the air without the use of heat. Warm mist humidifiers pose the risk of burns through their use of boiling water to produce steam. Refresh your air safely

Energy Efficient The boiling water used in warm mist humidifiers requires substantial electricity to run, making cool mist humidifiers the energy efficient choice.

Smart Power The Cool Mist Humidifier will automatically power off when the water tank is empty to prevent energy waste and let you know it’s time for a refill.

Virtually Silent Quieter than a whisper, our Cool Mist humidifier works silently to create an optimal environment for relaxation and sleep.

Straightforward Design There are no filters to be replaced. Humidifier filters can harbor contaminants like mold or bacteria that can be emitted into your air. Simple controls make it easy to change moisture and light output. Lights can be on or off.
