Venta LW44 Air Humidifier and Purifier All-in-one Review

Average Reviews:

(More customer reviews)Update on January 15, 2008:
Yesterday, the motor in my Venta unit began making a grinding sound after nearly six year of flawless operation. I called Venta customer service this afternoon. After wating a rather long time on hold, I was connected to a very pleasant man, George, who asked me to put the phone next to the motor so he could hear the noise. I did, and he did.
Without a moment's hesitation, George said he would have a new motor shipped at no cost to me, and that delivery could be expected within 5 - 7 business days.
It's always a pleasant surprise to find a company standing unquestioningly behind their warranty. If only more understood that's all it takes to create loyal customers.

Update on September 17, 2007:
I'm pleased to report , my review, below, is still true in every detail. This product has been a terrific investment.
*****
I live in a desert~like New York City apartment and have owned my Venta Air Washer for almost exactly two years. During this time it has been operating on the "high" setting, 24 hours per day, seven days per week. The Air Washer lives up to all of the manufacturer's claims.
The Air Washer is a product of fanatical German engineering, over~design and bullet~proof construction, which accounts for it's rather grotesque price. However, I have owned products of inferior engineering and construction that have had to be replaced after one or two seasons. It is obvious I will own my Air Washer for many years to come.
The principles of operation could not be more simple (it's like a High School science project developed into a luxury product):
1) A fan blows room air straight down into a reservoir of water.
2) In this reservoir of water, a few dozen disks are slowly rotating to multiply the surface area that is wet.
3) Because you are blowing air onto a enlarged wet surface you are multiplying the rate of evaporation.
4) Humidified air is exhausted out of the Air Washer through vents in the side.
THIS WORKS.
On the "high" setting the water reservoir needs to be refilled daily in my apartment (this is highly dependent on your local weather or heating cycle). I end up carrying a couple gallons of water to the device or carrying the device to the bathtub and then back to its spot in my livingroom.
The design of the Air Washer is "neutral." It sits unobtrusive and un~noticed in a corner. It is nearly silent. It is built like a tank: It would be a challenge to damage this product on purpose.
Why not Five Stars?
The Venta Air Washer consumes expendables. You need a water treatment solution to prevent mineral deposits forming on the rotating disks mentioned above (weekly). AND you need a periodic cleaning solution to remove deposits that develop pn the bottoms and walls of the reservoir. I have tried operating the Air Washer without these things. They are required for optimal performance.
Like the device itself, the Venta treatment and cleaning solutions work perfectly and simply. But, THE EXPENDIBLES ARE EXPENSIVE! Assume youy will spend US$50.00 per year.
Also, you would think that for a company selling a FIVE HUNDRED DOLLAR humidifier, the Venta aroma therapy scents would smell a bit less like a Central American bordello (not that I've ever seen one of those). Skip these even if they're free samples.
If you want the very best at any price, buy this product.

Air that feels good must be properly humidified. Heated air dries out the mucous membranes (weakening your resistance to viral infections). Overheated dry air makes you feel tired and listless. Your skin dries out, your plants suffer and your wooden furniture starts to show cracks. The Venta-Airwasher is ideal to reduce chapped lips, stuffed up noses, sore throats, and dried out eyes. Protect your valuable wood furniture and floors as well as musical instruments from drying out. Dry indoor air is difficult to clean; every movement causes millions of particles to be stirred up and become airborne.However, humidification keeps a large number of airborne particles down on the floor; making the two-in-one humidifier/purifier? more effective than air purifiers alone.The Venta Airwasher humidifies the air while simultaneously drawing in and removing dust, pollen and other contaminating particles down to 10 microns ( 10/1000 mm ) in size from the air. Easy maintenance. No filters to change or clean or cumbersome containers to fill. The simple design and convenient access to the tank allow for easy cleaning. 3 gal. tank capacity. Measures 16.5" x 11.8" x 13". 3 speeds. Humidifies/purifies up to 720 sq. ft. 10 Year Limited Warranty. Made in Germany

Sanyo ABC-VW24 Air Washer Air Purification System with Electrolyzed Water Technology Review

Average Reviews:

(More customer reviews)The thing I like best about the Sanyo Air Washer Purification System (besides that it does a great job of purifying the air) is that it has a nice sleek look to it and doesn't detract from the room decor. It has a handle built into the top, making it easy to carry (15.9 lbs.) and it's pretty quiet as air purifiers go. It has a 4-stage HEPA filter removes 99.97% of airborne particles and allergens. The other thing I really like is that the filters can be cleaned with a vacuum cleaner and are supposed to last for about 4 years. (You'd want to use a HEPA vacuum cleaner or you'd defeat the purpose.) I called customer service to ask about the price of replacement filters and they told me the suggested retail price is $69. That's pretty much in line with other filters I've researched. The customer service people were very helpful in answering questions about the unit which I count as a big plus.
I don't know if the electrolyzed water technology is just a gimmick or not, but the unit does a good job of cleaning the air and removing odors from any room that I place it in. There are several articles on the internet about electrolyzed water technology and electrolyzed water being used to sanitize water and possibly use it to kill bacteria in a number of applications including using it as a non-toxic way to clean fruits and vegetables in the food industry. It would make sense that it could be useful to kill bacteria and viruses in the air. With pets and all their dander, not to mention all the pollen and dust in the air this time of year, it gets a real workout around here. I hope that we find that we have fewer colds in the winter.
Just a few details that I didn't include in the video: I measured the watts that the unit takes at the low, medium and high speeds with a P3 International P4400 Kill A Watt Electricity Usage Monitor device. At low speed it uses 4 - 8 watts (the higher number when it's emitting the electrolyzed water. You'll see that in the video.), on medium 13 - 17 watts, on high 57 - 63 watts, and if you use the "power" setting, 63 - 65 watts. This compares favorably with other air cleaners that I've used in the past or use now and it seems to work more quickly at removing odors.
BTW, another reviewer had mentioned that the "Device contains a chemical known to the state of Caifornia to cause cancer, birth defects, etc." Living in California I'm used to seeing these warnings on just about every piece of electrical equipment I buy due to the "Prop 65" laws here. Nonetheless, when I called Sanyo, I asked about this warning and what part of the unit had the chemical. As I expected it is the lead in the electrical cord connection, the same as my computer. When handling electrical cords it's always a good idea to wash your hands afterward.
I hope the video is useful. It's difficult to tell from a small photo what the unit looks like and I wanted you to have a better idea of how it worked and what it sounds like.

Sanyo's new Air Washer air purification system suppresses airborne bacteria and germs utilizing an exclusive electrolyzed water technology, removes dust and allergens, reduces pollen and neutralizes odors. Sanyo's electrolyzed water technology has been tested and proven effective in suppressing airborne germs, bacteria, odors, allergens and mold through third party certification institutions including RTI. In addition, electrolyzed water has proven effective in significantly reducing the level of viable airborne germs and bacteria, according to an independent research institution in the United States. Simply add tap water to the water container and the chlorine ions in the tap water are molecularly split through an electrolysis process in the unit into electrolyzed water. The electrolyzed water attacks the protein spikes in bacteria and inactivates the spikes so they are unable to attach to human cells. The units' 3 directional (upward, leftward, rightward stream) airflow emits the purified air and extremely fine electrolyzed water mist to quickly clean the air throughout the room. A High Performance 4-stage HEPA filter removes 99.97% of airborne particles and allergens, reduces airborne pollens with allergy blocking filter and fights common odors including pet dander and tobacco smoke. The sleek design is simple to operate, has an automatic timer function and filter replacement indicator.
