William Ultrasonic Humidifier in Black Review

Average Reviews:

(More customer reviews)I recently moved to Aurora, Colorado (just outside Denver) and at 5,400 feet the humidity is extremely low. I noticed my skin began to itch, which it had not done before. My doctor advised moisturizing creams, which helped a bit, and an air humidifier. After a lot of investigating I narrowed my search to the Air-O-Swiss and the Williams. In fact, both units seemed remarkably similar with both using a "patented" ionic silver cube and a filter cartridge which seem visually identical. Both units provide warm and cool mist. Possibly the technology is licensed from Air-O-Swiss? The deciding factors for me were:
(a) the Air-O-Swiss listed a capacity of 650 sq. ft. and the Stadler 1,000 sq. ft. I have a very small house - 850 sq. ft. - which effectively makes the Stadler a whole house humidifier for me.
b) almost every review of the Air-O-Swiss commented on the inaccuracy of it's humidity meter and the only review I could find of the Stadler said it's meter was accurate.
THE GOOD: Assembly is a snap. The meter is close to accurate. The water tank is extremely easy to remove and fill. It is dark plastic, but the water level can be seen quite clearly. The tank capacity is sufficient for 9 hours of continual use. The machine is so silent that I have to listen closely at night to hear anything at all. Just a soft "ssshhh." The Control Panel is easy to see and use with many options and has a light to indicate no-water.
My skin itching stopped.
THE NOT SO GOOD: It is expensive and every source I could find had the same price. The filter cartridge needs to be replaced three or four times a year, depending on the hardness of your water, or when white dust accumulates on the unit or on a small mirror held to the fog. The ionic cube must also be replaced once a year. A testing strip is included and if your water has a hardness greater than 21 degrees dH, an ionic humidifier is not recommended. They suggest then using an impeller humidifier. The Desired Humidity cannot be set lower than 40%, but I found that setting it at 60% results in an actual humidity level of about 37% which is what I want anyway.
THE BAD: I couldn't find any.
SOME NOTES ON OPERATION: The instructions say not to place the Stadler Williams directly on the floor or next to heating. I went to Ace Hardware and found a small, plastic step stool for $12 that is 5" high. This keeps the unit off the rug and makes it easier to access when changing settings. If you have an chest of drawers in the room with space on top it should work equally well. A review of the Swiss-O-Air reported good results from soaking the ionic cube in water for 24 hours before initial use to increase effectiveness. I don't know if this is beneficial, but I did it and had no bad result.
I set my unit to Auto/Sleep
IMPORTANT: Several reviews of the Air-O-Swiss said that they used de-ionized water. The Stadler unit specifically recommends against this. It is designed to use with untreated water or with a drinking water filter system such as Brita. Using any additives are specifically warned against.

Air-O-Swiss 32838 Ultrasonic Humidifier Review

Average Reviews:

(More customer reviews)WHEN it works it is OK. It has all of the defects described by the other reviewers. But they make up for the defects with rotten customer service. I bought this unit on January 31 07. Used it until the end of March, at which time I cleaned it and replaced all of the consumables per the instructions. I put it back in service two weeks ago. Six days ago it stopped working. I called their customer service. They use an out-sourced customer service group that will NOT talk to you, but rather, insists on taking your number and calling you back in the evening. Of course, they called back when I was out and left a message that they would call the following evening. They did not. I called back the next day and went through the same thing. That evening, since thay had not called by 8:30, I called them. This time, they insisted that I go through some trouble-shooting (all of which I had done previously). They then told me to leave it unplugged for a 1/2 hour (by which time they would be gone) and then "reset" the unit by pressing a button combination. I did this. The next day I called them again and got the same "wait until tonight" pitch. I insisted on an RMA number, which I received. HOWEVER, before they will tell you where to ship the unit, you need to FAX them a proof-of-purchase (their email address bounces back). The you have to wait for them to call. It is now 6:30PM on a Friday night and no call. So I called them and got their voice mail, where I was instructed to leave a message. So It will not get shipped to them this week. Next week I am traveling, so it won't get shipped until the following week, which means that they will not get it until after Christmas, which means it will be mid-January before I get a repaired unit. These people are total idiots. For a $200 humidifier, I would expect some sort of real customer assistance. Be warned before you buy.
UPDATE: Well, a month after I sent the defective unit in, I received a TOTALLY DIFFERENT AND MUCH CHEAPER UNIT in return. I am now on my THIRD phone call with these idiots and have yet to talk to someone who can resolve this problem. The right person is "not in the office" and will "call me back." HAH!! They NEVER call back. I wish I had never heard of these people.

This efficient Air-O-Swiss Ultrasonichumidifiier uses several cutting edge technologies to achieve an optimum quality of environmental control. High-frequency vibrations generate a micro-fine mist, while an Intelligent Temperature Compensation system (ICS) measures humidity relative to the room temperature and automatically adjusts the output to achieve an optimum balance dynamically as conditions change. The water is kept clean with three separate processes that make up the Microbial Protection System: ultrasonic technology, pre-heating, and Ionic Silver Stick. The latter makes use of the proven anti-microbial qualities of Silver, which has proven effective against more than 650 types of bacteria without any chemical additives. When operated with the pre-heating function, the water is heated to 176°F before it enters the nebulizer chamber. The mist exits the appliance at a comfortable temperature of 104°F. This neutralizes the cooling effect of mist to keep the room temperature from falling, and also keeps the water cleaner. A replaceable demineralization cartridge ensures a hygienic, pure water mist, without lime scale or mineral residues. Exchangeable demineralization cartridge / Quiet operation /Easy to clean and handleSuitable for rooms up to 860 sq. ft. Power consumption -40W w/o pre-heating, 140W w/ pre-heating / Moisture output -up to 3.5 gallons / 24 hrs Water capacity -2.0 gallons Dimensions -9.8 x 11.0 x 17.3 Weight -8.0 lbs.

AIR-O-SWISS 2055 Ionizing Air Washer & Humidifier Review

Average Reviews:

(More customer reviews)Having been directed to an evaporative type humidifier, I became intrigued with the basic design of the Venta and AirOSwiss models. Both use fans to draw air over water, with turning discs passing through the water with tiny grooves and bumps on the discs to vastly increase the surface area over which the water evaporates. No heat to worry about drying out and automatically shutting off, and no bubbling water from a warm mist unit. Also, no droplets of water accumulating on nearby carpet or furniture as you would see with an ultrasonic humidifier. Also, no swampy mold accumulating in the 'swamp style' Honeywell unit that uses a wicking method to draw the water up into a sponge to then be evaporated, leaving a wet sponge to grow all kinds of stuff. The pros and cons are pretty clear:
Pros: No heat to worry about if the unit runs dry- the fan keeps running but so what? It's just a fan; also no 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. No wicking sponge, so the discs are easily removed and cleaned and no 'swamp thing' accumulating in the wet wicking sponge as in other units. Also the water seems to trap small air particles so that there is an actual cleaning function. Air is drawn IN through the TOP of the unit, blows over the plastic turning discs, and comes out the sides.
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. Also, it won't shut off when water runs out, so power will be consumed with no humidification happening. See below for the one last 'con' relating to the warranty.
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 over 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!) inside. 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 but it took a number of emails and phone calls, so this is not exactly the fastest responding company I've seen. Also note, the 10 year warranty does NOT apply to the water tank and its part . . .that's only 3 months.
For [...] 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 in a space is dependent on the room's air flow, items of absorbency, and atmospheric conditions- none of which are in the control of a humidifier! This item definitely puts out the water into the air.

Stadler Form VIKTOR Air Purifier Cleaner 12-18W, White Review

(More customer reviews)Good System, but didn't quite catch much dust as expected, however, it works great for odor.

Air in rooms is often burdened by fine dust, pollen and unpleasant odors as well as viruses and bacteria. But VIKTOR filters all this through a specially developed HPP Filter System TM (International patent application pending), thus permitting you to take a deep breath of fresh air! Small and yet great in his own way - VIKTOR clearly demonstrates what clean air is all about with top CADR values (Clean Air Delivery Rate). The special filter cleanses the air while active carbon eliminates unpleasant odors. And with five capacity stages (extremely quiet to powerful) and dimmable night-mode LED control lights, VIKTOR will always be a fine companion!

AOS 2055A Automatic Air Washer 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, and it traps air particles on the discs with the water so it does 'wash' the air.
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!).

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.

AOS 2055A Automatic Air WasherHumidification SystemThis 2 in 1 Humidifier & Purifier washes and humidifies a room's air without evaporator mats. Special humidifier discs turn through the water removing impurities from the air naturally, which gives great relief to allergy sufferers. Therefore it is called an Air Washer. The discs, which never need replacing, have a great adhesion for water to guarantee high humidity output. The Air Washer is equipped with the Ionic Silver Stick (ISS) anti-microbial protection system that helps prevent microbial growth in the water base. Microbial protection is particularly needed when the humidifier is not used for some time with water remaining in the base. The AOS 2055A automatically switches off when the water base is empty.Comfort and ClimateThe pre-ionizer charges particles as they enter the air washer. These small charged particles, down to 1.5 microns, form larger dust clusters that cling to the humidifier discs and are removed as the discs turn through the water.

VENTA AIRWASHER LW24 Air Humidifier and Purifier All-in-one Review

Average Reviews:

(More customer reviews)At low speed you won't even know it's on and it's still quiet at med. and high speed too. We normally run it on medium or high speed when the weather is 35 or colder here in New England and turn it down to low if the temperature outside goes up or it's raining out. Doing this keeps the humidity in the house a pretty constant 40-45 per cent. We have a Colonial house and keep the upstairs bedrooms closed so the unit is just taking care of aboout 1100 ft. downstairs. I fill it in the morning and just before bedtime. They only hold a few gallons of water, but what a difference they make. We have had hardly any colds since we bought ours a couple of years ago, and we're not constantly having to put on lip balm or hand lotions like we used to. Your skin will thank you for it. But wait...there's more...hehe...Wait til you empty and clean it like I do every 2 weeks. The water you dump in the sink...unbelieveable what this unit takes out of the air. Remember, it's an air purifier too. It's amazing to see the junk that's in the dirty water. Stuff you would normally be breathing in.
It's light weight and small enough to be unobtrusive. I had a problem with mine the second year...called the company and within 3 days had a replacement part that was a snap to install, free of charge of course. Fantastic 10 year warranty.
Proof of how much we love this unit...the day it broke was a Sunday and dry as a bone...temp in the teens. Within an hour I was home from Bed and Bath with a new unit. Didn't even want to go 3 days without one running. Now we run them both on low speed most of the winter.
Check out their website...commercial buildings all over Europe use them as well as musicians with expensive wooden instruments to protect. Little known product just introduced to the US a couple of years ago. Highly recommended.
