  • Product Overview

    Perform double-duty on your indoor environment by humidifying and "washing" the air with the popular Air-O-Swiss AOS 2055A Automatic Air Washer Humidifier. Using impeller humidification technology, the Air-O-Swiss 2055A removes large particles and allergens while dispersing a cool mist of moisture into your room. This 2-in-1 combination unit is designed to humidify and "wash" the air in spaces measuring up to 600 square feet.

    How It Works

    Naturally ideal for allergy-sufferers, the Air-O-Swiss AOS 2055A Air Washer Humidifier uses a dual process to create healthier, humidified air. As air is drawn into the humidifier, it passes through a series of 16 rapidly spinning discs that attract large particles and allergens while a continuous bath of water rinses them away. Afterward, the spinning discs break down the clean water into tiny droplets that are released into your room as a purified invisible mist. This air washer humidifier produces 3 gallons of cool, clean moisture each day.

    To ensure its effectiveness in removing large particles, the AOS 2055A Automatic Air Washer employs a pre-ionizer to charge particles as small as 1.5 microns as they enter the unit. These charged particles attract other particles to become larger and thus, more readily removed during the air-washing process. Because it reduces the amount of allergens in your air, this air washer humidifier can also help reduce your mild allergy symptoms.

    Please note that an air washer is not as effective as an air purifier for removing smaller particles and allergens. If you suffer from moderate to severe allergies, please consider using a HEPA air purifier, which can remove microscopic particles and allergens sized down to 0.3 microns. These are often the types of particles that prompt severe allergy symptoms to develop.

    Additional Features

    Along with using health-boosting air-washing technology, the Air-O-Swiss 2055A Air Washer features:

    • 2 Humidification Speeds – Select from normal and nighttime settings to suit your preference.
    • Rotary Dial Control – Easily choose your desired settings with the no-frills manual dial control.
    • Water Refill Indicator – The operation indicator switches from green to red when it's time to refill the air washer. You can also keep a close eye on the water level through the transparent water reservoir.
    • Automatic Shutoff – No worries if you can't get to the humidifier in time for the next refill. An automatic shutoff function automatically powers down the unit until you can refill it.
    • Fragrance Container – Add a cotton ball soaked in a pleasant fragrance to this optional container and enjoy the aroma as you humidify, wash, and deodorize your air.
    • No Replacement Filters – This impeller humidifier requires no replacement wicks, demineralization filters, or evaporator pads—saving you money on maintenance costs.
    • Quiet Operation – Like other Air-O-Swiss humidifiers, the Air-O-Swiss Air Washer 2055A operates quietly at less than 25 decibels, which is quieter than the sounds you hear in a library.

    Air Washer

    By Susanna Oppedisano

    from USA

    Comments about Air-O-Swiss 2055A Automatic Air Washer Humidifier:

    Product sends moisture into the air, since the water level goes down, but I don't feel like there is any more moisture in my room than usual. Also, have no way of knowing how clean the air is or if this feature is actually working. There is nothing to measure it.
