  • Product Overview

    Colder temperatures outside often means lower humidity inside. Dry room air from low humidity can lead to physical discomfort and severe allergy irritation. Restore your indoor breathing environment with the Air-O-Swiss 7135 Digital Ultrasonic Warm & Cool Mist Humidifier.

    Recently recommended by a leading consumer reporting magazine, the Air-O-Swiss AOS7135 adds up to 3.5 gallons of moisture per day and humidifies areas as large as 650 square feet. Just add water and this ultrasonic humidifier distributes a micro-fine mist into the air, providing instant relief from the harmful effects of dry air.

    This home humidifier features the following benefits:

    • Water Level Indicator: When the water tank is empty, the water droplet symbol will illuminate to remind you to refill.
    • Innovative Design: The Air-O-Swiss features advanced technology and a transparent water tank.
    • LCD Display: The Air-O-Swiss 7135 humidifier is easy to use and simple to operate with the control panel’s digital display.
    • Minimal Noise: Air-O-Swiss humidifiers provide optimum air humidification with whisper-quiet operation.
    • Clean Indicator: When it’s time to clean the humidifier, “clean” will appear on the display. This indicator will light up every two weeks, depending on the level of use.

    Releases Micro-fine Mist

    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 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.

    The Air-O-Swiss AOS7135 Digital Ultrasonic Warm & Cool Mist Humidifier replaces dry room air with comfortably moisturized air. The Air-O-Swiss 7135 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.

    Prevents Germ Growth

    When you have a low humidity problem, the last thing you want to worry about is germ buildup in your humidifier. Clean water in your humidifier base equals fresh, germ-free moisture in your space. The Air-O-Swiss 7135 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 microbial 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 AOS7135 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 three months.

    Achieves Ideal Humidity

    Maximum comfort is at your fingertips with the Air-O-Swiss 7135 Digital Ultrasonic Warm & Cool Mist Humidifier. With a programmable timer, hygrostat, and several mist output options, this home humidifier helps you reach your ideal room humidity with the simple press of a button.

    Set and maintain your desired humidity level with the built-in hygrostat and programmable timer. 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 low, medium, or high mist output, the Air-O-Swiss 7135 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.

    Operates Automatically

    For easy operation, the Air-O-Swiss 7135 Ultrasonic Digital Humidifier features automatic and sleep modes. The Air-O-Swiss 7135 humidifier operates for 8 hours in sleep mode, during which a 60% relative humidity is maintained. Continuous operation is also offered with the Air-O-Swiss AOS 7135 Humidifier.

    In auto mode, the humidifier monitors your room temperature with Intelligent Temperature Compensation technology and automatically adjusts the mist output when conditions change. Using the pre-set humidity level, the humidifier cycles on and off to maintain optimum humidity.

    Comments about Air-O-Swiss 7135 Ultrasonic Digital Humidifier:

    We got this to help with my wife's allergies/sneezing per doctors recommendation. Seems to do a great job! Very quiet, works well, sleep mode wants to go to 60% humidity which is a little overkill in my opinion (we keep it around 45-50% instead). Maintenance could add up if you have bad water, but our water is good so we've been able to skip some of the cleanings so far. Would recommend this device. Only bad thing is its kind of weird looking and doesnt really fit into any type of decor.

    wet rug

    By Barbara

    from USA

    Verified Buyer

    Comments about Air-O-Swiss 7135 Ultrasonic Digital Humidifier:

    I love the Air-O-Swiss humidifier for some of its qualities--quiet, lots of vapor when needed--but have 2 concerns, too:
    (1) I have the humidifier about 3 feet above my bedroom's carpeted floor. Unfortunately, the vapor falls to through the air and drops in a fairly small area on the carpet; the carpet is always wet.
    (2) It's awkward filling the tank. When I hold it under the faucet in the tub, it gets progressively heavier as it fills and it's extremely hard to maintain my hold. I fear the day it slips out of my hands and breaks on the ceramic tub. by the way, I sort of solved the problem by putting a portable wire shelf in the tub--kind of a Rube Goldberg solution.
    Other than those two concerns, I'm happy enough.

    Comments about Air-O-Swiss 7135 Ultrasonic Digital Humidifier:

    This humidifier works great, it is far superior to any other humidifier I have ever owned before. Would highly recommend it. The only complaint I have is that it could be more attractive looking.
