This 2-in-1 humidifier and purifier washes and humidifies a room's air without evaporator mats or pads.
Special humidifier discs turn through the water removing impurities from the air naturally, which gives great relief
to allergy sufferers. The discs, which never need replacing, have a great
adhesion for water to guarantee high humidity output. And the process of using multiple discs also works to increase output by
increasing the evaporative surface area inside the unit. The AOS 2055A is portable at
around 13 pounds, and it will be effective in rooms or living spaces up to 600 square feet.
What I like about the Air-O-Swiss 2055A Air Washer
The best quality of this humidifier is how easy it is to clean and operate. There are no replacement filters or
evaporator pads needed. The water tank is transparent and easy to remove. Air washers, by design, are meant to help remove impurities from the air. With regular cleaning you will notice that this unit does
trap some particle pollution. While it cannot take the place of a true air purifier, for older or dustier homes, this is a nice
The tank capacity if larger than nearly all other Air-O-Swiss humidifiers available. At just under 2 gallons, even under the driest
conditions you'll likely only fill this unit twice in a 24 hour period.
While the controls of this unit are the basic controls of the original 2055, the AOS 2055A has an automatic shut-off feature that
the original model lacked. So when the tank is empty, the unit shuts itself off.
This humidifier uses a Hydro Stick that prevents microbial growth in the tank's water. There is no need to
add chemicals to improve water quality. This accessory for the humidifier only needs to be replaced once a year.
Energy usage for the Air-O-Swiss 2055A is very low. It will run all day for a fraction of what it costs to power a standard
light bulb. This unit is also very quiet with near silent operation.
Lastly, there are no demineralization cartridges to replace. Because this unit operates on the principle of evaporation, mineral
content in the water simply settles in the tank itself. This turns the cost of replacing or refilling cartridges into simply wiping the
bottom of the reservoir out with a damp cloth.
What I do not like about the Air-O-Swiss 2055A Air Washer
Compared to some models, the AOS 2055A does not put as much moisture in the air as quickly as ultrasonic humidifiers. In general,
evapaorative humidifiers are all like this. Still, the Air O Swiss 2055A is built to meet the humidification needs for most rooms.
In summary, the AOS 2055A combines extremely simple operation with minimal energy use. The AOS 2055A is near silent, and its sleek design
minimizes its footprint in your bedroom or living area. While the air cleaning ability of this air washer won't take the place of a
true air purifier, the particle pollution removal is an added bonus not found in ultrasonic or other evaporative humidifiers.
