Air-O-Swiss Air Washer - Black/ White (2055) Review

Average Reviews:

(More customer reviews)For details, including photos of the internal workings of this evaporative humidifier, look for the 2055 AirOSwiss reviews done elsewhere on Amazon which has plenty of images of the inner workings. To summarize, it's an evaporative humidifier which works by drawing air in through the top via a fan then over a disk pack of about 10 slowly rotating plastic disks which dip into a pool of water, then the air exits the side carrying the humidified air.
Pros: No heated element to worry about overheating when it runs dry, no ultrasonic misting to leave water droplets on carpet/furniture, easy to clean, no filters to be replaced.
Cons: Evaporative which means it cools (fine for the desert country, not so good in winter in the Midwest), no heating, and the fill valve on the water tank is the stupidest location you can imagine, so that at best you can fill it only 3/4 full.
The other con: They SAY on their website they have a 10 year warranty, yet when I got this thing from Bed Bath and Beyond the plastic shaft inside had corroded from time and was crumbling. It was a major effort to get these guys to agree to replace it. It is NOT SAID on their warranty, but apparently the 10 year warranty does not apply to the rotating disc set (surprise!). I told them they had better put that in writing if they don't want to tick off a lot more customers other than me. They eventually replaced it. Also note, the 10 year warranty does NOT apply to the water tank and its part . . .that's only 3 months.
For $260 bucks or more, the above limitations cut it to a 3 star, even though it's a reliable humidifier that cranks out the humidity from the unit with no filters and very little maintenance. As a personal aside, I can't stand the reviews which deride humidifiers because their hygrometers show no change. Humidifiers can only be evaluated by how quickly they put water into the air . . . the ultimate humidity change is depending on the room's air flow, items of absorbency, and atmospheric conditions- none of which are in the control of a humidifier!
