Air-O-Swiss 2055A Air Washer & Humidifier

Sharing features from both the 2055 and 2055D, the Air-O-Swiss 2055A Air Washer & Humidifier is a simple, yet effective way to put needed moisture back into your indoor air while removing particulate and dust that can negatively effect indoor air quality. Air washers feature a slightly different humidifying technology that uses a series of discs and evaporation to restore moisture without any need for a demineralization cartridge. And with low power consumption and extremely quiet operation, the AOS 2055A is one of the most unobtrusive and low maintenance ways to improve indoor comfort throughout the year.

With the Air-O-Swiss Air Washer and Humidifier, you'll never have to worry about changing filters because there are no filters to change! As the disc rotates through the water, water bathes each disc. Impurities and particles in the air, like pollen, pet dander and other common particle allergens attach to the discs as air circulates in from the sides of the unit. A pre-ionizer gives each particle a very small charge causing them to attract and for larger particles that adhere to discs. As the water evaporates and is dispersed throughout the room, the particles remain, and because the basic principle of evaporation is what drives this unit, there is little to no chance that minerals are released in the air. This also means there are no demineralization cartridges to replace. When dirty, simply remove and wash the discs, wipe out the tank, and the Air Washer is ready to go!

  Air-O-Swiss 2055A
Reviewed by:  from Asotin, WA

This is our second Air-O-Swiss. The first one ran continuously for 10 years before the motor gave out. We use it in the bedroom. It goes through 5 gallons of water a day which is much more than pad-type evaporative humidifiers. Never a problem with mold growing on the pads since there are no pads. It also pulls a lot of stuff out of the air. It seems expensive and honestly is! but worth it in the long run.

My ENT Doctor recommended that I purchase a humidifier for my sinus problems. The Air-O-Swiss Air Washer and Humidifier allowed me to sleep through the night and wake up without feeling congested. It is very quiet and little to no maintenance is required. I highly recommend this product.

Customer Q & A

Q1: the 2055a states that there are little to no minerals released to the air. will this eliminate the white dust i get from my past humidifers ultrasonic type

A: It should, yes. The ultrasonic humidifiers sometimes put a white dust into the air when there is no demineralization cartridge to remove mineral content from tap water. The solution to this is replacing or using a cartridge or using distilled water. With the AOS 2055, moisture is put back into the air by evaporation. So there is no diaphragm that is aerosolizing water into mist. Any mineral content in the water will collect in the base of the unit and on the plates. This can be wiped out once dry or removed with a bought or homemade descaling solution.

Air-O-Swiss 2055 Air Washer Reviews
Air-O-Swiss 2055A Air Washer and Humidifier

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 added benefit.

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.

Why buy from Customer Testimonials
My son has always had a nagging cough when the weather gets colder, that persists all winter long. The Vornado Humidifier  seems to have helped him feel better, and I don't hear nearly as many late night coughing fits. Thanks!
