Effective Air Humidification

A lack of moisture in the air can irritate your allergy and asthma conditions and cause chapped lips, red eyes, and itchy skin. The Air-O-Swiss 7133 Ultrasonic Warm & Cool Mist Humidifier replaces dry room air with comfortably moisturized air. The Air-O-Swiss 7133 uses high-frequency vibrations to generate a micro-fine mist. The humidifier surface is made of an industrial-grade titanium membrane material, which accelerates the mist release into the air.

The Air-O-Swiss ultrasonic humidifier reverses the effects of cold winter air with ordinary tap water. First, fill the water tank with clean, cold water while the humidifier is unplugged. As the water passes down through the base of the humidifier, it flows through the demineralization cartridge. After mineral deposits are removed, the water evaporates to create a fine mist and is distributed throughout your space.

Germ Protection

When you have a low humidity problem, the last thing you want to worry about is germ and bacteria buildup in your humidifier. Clean water in your humidifier base equals fresh, germ-free moisture in your space. The Air-O-Swiss 7133 humidifier is specifically designed to keep reservoir water clean for longer periods of time.

Air-O-Swiss ultrasonic humidifiers feature a four-layer defense system that prevents germ growth in the reservoir and ensures exceptional water quality. At the heart of this germ protection system is the Hydro Stick. Lasting for one year, the Hydro Stick helps maintain a cleaner reservoir so the humidifier continuously produces fresh moisture.

Additionally, the Air-O-Swiss 7133 Ultrasonic Warm & Cool Mist Humidifier is equipped with a demineralization cartridge. This cartridge prevents white dust from forming in your humidifier. The demineralization cartridge is housed in plastic that has been treated with Ionic Silver Technology. The ionic silver technology keeps microbes from growing on the surface of the cartridge. The demineralization cartridge should be soaked in water for 24 hours before use and replaced every 2 to 3 months.

Controlled Operation

Maximum comfort is at your fingertips with the Air-O-Swiss 7133 Ultrasonic Warm & Cool Mist Humidifier. With a built-in hygrostat and several mist output options, this home humidifier helps you reach your ideal room humidity with the simple turn of a dial.

Set and maintain your desired humidity level with the built-in hygrostat. The hygrostat allows you to program your desired humidity level in increments of 5 percent. Once the moisture level reaches the desired setting, the humidifier will automatically shut off.

In addition to allowing you to choose from low to high mist output, the Air-O-Swiss 7133 ultrasonic humidifier offers cool or warm humidification. In warm mist operation, the water in the tank is pre-heated to 176 degrees Fahrenheit. The water takes 10 to 15 minutes to heat up and a warm mist is released into the air at 104 degrees.
