Venta Airwasher Humidifier
The Original For Your Health and Wellness
The Venta Airwasher fulfills two purposes: it humidifies dry indoor air while simultaneously purifying it. Dry indoor air is drawn into the unit and passes through the disk stacks which rotate in the water. The air is literally washed. Even the smallest particles are trapped in the water. At the same time, pure water evaporates on the exchanger surfaces, which is widely recognized as the best method of cold evaporation.
Simple. Healthy. Without filter or filter pads.
Cold evaporation offers decisive advantages. The air is perfectly humidified. There is no need to worry about over-humidifying or lime deposits and no need for lime cartridges.
2-in-1 Benefits of Humidification and Purification
The Venta Airwasher uses the principle of humidifying and purifying air for homes and offices without using filter pads. The Venta Airwasher is hygienic, simple to use and easy to clean.
Using a Venta Airwasher will help to reduce common cold symptoms and cough due to dry air. Relieve congested nose, dry skin, and chapped lips. Keep allergies under control against dust mites, animal dander, and pollen. Perfect indoor air quality helps to improve concentration and reduce headaches. Properly humidified air will also eliminate static electricity and work to preserve wooden furniture and musical instruments.
Venta Airwashers offer consistent performance of high end German engineering; delivering perfect indoor air quality.

Venta Water Treatment Additive
The Venta Water Treatment Additive is designed for the Venta Airwasher models to maintain hygienic conditions in the lower housing and to improve the evaporation process.
It creates a sheeting action on the disks to maximize the surface area coated in water – this aids in the evaporation process. The Water Treatment Additive also helps prevent calcium and lime build-up.
Important: the ingredients of the Venta Water Treatment Additive do not evaporate. They remain in the unit until poured out for cleaning (approximately every 10 to 14 days). Only fresh water should be added daily – this reactivates the contents of the Venta Water Treatment Additive.
Contains 35 fl. oz (sufficient for approx. 5 months).
Recommended usage: one dose every 10-14 days.
The Venta Cleaner has been specifically formulated for the thorough cleaning of our Airwashers. The Venta Cleaner should also be used before the storage of the device to ensure that all residues are removed.
Contains 8 fl. oz. (sufficient for one cleaning).
Recommended usage: once every six months.
Eucalyptus fragrance is comforting during the cold and flu season.
Vanilla fragrance is warm and inviting.

Does it humidify?
It's questionable, maybe more like maintains the humidity levels from dropping too fast. Why do I say this? Because I don't see the humidity levels drop or spike when I'm not using or using the unit. I have a pretty fast reacting hygrometer which detects the changes in 30 minutes max.
Does it clean air?
For sure it does, simply because the water in the tub gets dirty. But how big of a radius does it really affect? I'm not sure, I have no proof either way.
My nose never said "ohhhh this air feels so great" when I would walk inside the room where it's used. But I keep using it, in good part because it's so universally praised, and I paid for it.
I had mine for close to a year. First few months you could keep it in the bedroom where we sleep. But then it developed this clickity/clackety noise, stuttering clicking sound. That made it not bedroom quiet. I tinkered with it a lot, read tips from Venta themselves, and various advice on the internet and this collection of reviews. It's successful for a few hours but the clicking always returns. So during day it's in our bedroom and during night in the living room. Usually on #2 setting.
So while it's humidifying and air cleaning properties are just my subjective opinions, this noise is definitely a disappointment.
My first big gripe is how Venta marketing makes you think it's low maintenance.
OK how, compared to other humidifiers I guess?
It takes same amount of work adding water daily and cleaning if not more.
My warm mist humidifier I'd add water daily and clean it once a season to get rid of calcium deposit.
Venta takes adding water daily, cleaning every couple of weeks, and at least once a season I disassemble it to clean the fan housing.
And the basic cleaning is not that quick either.
You have to clean both the plastic cylinder and the tub. Depending on how dirty the air was, the tub needs to be rinsed or scrubbed.
The cylinder is the worst part.
I would soak it in vinegar and then run it under water from the shower with a very strong jet stream and the slimy gunk would fall off it the plastic cylinder for half hour. A lot of it. The cylinder would be completely coated with it.
Well that was before I started using the water additive.
Then I decided to give this additive a try.
It works! For cleaning part at least, someone here noted how it became much more effective as a humidifier as they start using water additive. I haven't noticed a difference. At least nothing that would make me say "wow it's so much better now!"
But with cleaning it helps big time.
After a couple of weeks the plastic cylinder has barely any of that slimy gunky stuff.
OK so that became quick and easy.
But there's added cost. And you're dumping the additive to the water stream.
I'm not a chemist but is this really that eco-friendly as other blurb of their marketing makes you think?
Then there is a slight deception from Venta. Or maybe an honest mistake?
When you buy a bottle of additive it gives a standard measure of 3.5oz per application.
But then I remembered, when I bought this thing it came with a sample.
Well what do you know?
On the sample bottle it says LW15-25 is using 1.75oz and LW45 is using 3.5oz.
Does this bit of info exist of the 35oz bottle?
Just says "One dose of Water Treatment Additive is 3.5 fl oz equal to one black marking on the left hand side of the label"
Mistake or tricking the consumer to spend twice as much $ as they need?
On the Venta site it says:
11 reasons people insist on Venta Airwashers
Can never over-humidify: true but in a sarcastic-ironic way, not in a way "we'll bring a humidity where it should be but too much of it"
No filters no trash: true but you're dumping water additive to back to the water supply
Hygiene no more germs: I got sick twice this season while in the last ten years I either get sick once of not at all, but it's hard to be objective on this.
Low maintenance: compared to my warm mist humidifier totally false as I mentioned in my review above
Use very little power: true but is there any benefit compared to every other humidifier of similar capacity? So if you're doing the same job as every other guy how is that the advantage for you that you decide to market yourself with?
Eco-friendly: same as No filters, no thrash line, you're dumping water additive back to the water supply stream, how is that Eco-friendly?
Extremely simple to use: true but same can be said of just about every humidifier, OK this is getting repetitive.
Very simple to clean: false, in my opinion, you have to clean the tub, the plastic cylinder and occasionally the fan housing
Easy to fill with water: true...whatever
Made in Germany: true and it's nice to see Germans keep their manufacturing in their country, the downside is the price at least 5 times and probably more of the humidifier of similar capacity
Premium quality: true but just because I don't wanna come across as a nit picky thrasher of the Venta Airwasher, on the other hand what's so premium about it? It's plastic and none of it has a Rolls Royce feeling. It's impressively designed and put together but we're accustomed to see that from Germans, I mean they are truly the kings of industrial design.
So there you have it, I hope I didn't just completely waste a couple of hours of my life and someone will actually read this.
Now I've lived with this unit for 3 years and have encountered further problems that have finally driven me to admit this whole purchase was not a good idea.
The first problem with this unit is that the "air washing" capability results in the machine getting dirty... but unlike almost every other kind of humidifier this dirt is everywhere on the machine - throughout the disks, all over the fan, all inside surfaces. On the inside surfaces (which have lots of hard to clean nooks) this dirt is similar to a sticky wax and on the wet surfaces its more like a slime. I spend about 30 minutes struggling to clean it each time I try before I feel I've done an OK job. The Venta cleaner additive doesn't work that well on the disks, doesn't do anything for the waxy sludge on the housing because it doesn't touch it, and the unit has so many difficult to clean parts that it's nearly impossible to get all the dirt. I even tried putting the non-electrical parts in the dishwasher which doesn't work either.
The second problem is that this device can "easily" generate very loud noises to the point that I have to shut the machine off because I'd rather be tormented by dry air than this devices groanings. I say easily because it is possible with enough cleaning and fiddling to keep this device operating at the "merely loud" fan noise that it had when I got it. But after 3 years this is becoming very difficult to accomplish. There are two possible sources for this noise. First, the gears themselves operate by having plastic tabs press against the gears in an undulating fashion. When clean this usually happens quietly... but when even slightly dirty these tabs can make a loud studdering noise that is caused by two materials not moving against each other smoothly. If you've ever heard your car's windshield wipers studder across your windshield instead of smoothly glide over the glass you know what this sounds like. It's not quite that loud, but when you're trying to sleep it might as well be. The second source for this noise is imbalance in the fan. With a little dirt on the leading edge of the fan the fan seems to be aerodynamically or statically out of balance and makes an undulating groan about every 4-6 seconds the way an old fan can be expected to. On a $15 room fan it would be the kind of noise that might cause you to throw it out and get a new one. On a humidifier this expensive?
Finally the device is sensitive to being assembled in just the right way or it will make the noises I've mentioned above much more easily. Normally you just put the top on the device and you're in business. But with these noises you start pressing on different parts of the top to try to shift the plastic pieces into better alignment. Once you press in just the right way and the device stops making noise you slowly remove the pressue and 99% of the time the noise comes back. If you push and prod you are sometimes able to get the machine to be quite, but often you have to unlatch everything, reseat the fan assembly and start over. That gets old fast when its 3am and the machine just starts making a really annoying noise that wakes you up.
I call my 3 year journey with this Venta machine a battle because I've tried tons of things to help compensate for this machine's problems. The initial problem of low humidification is because the device sets up its own recirculating airflow that's limited to an area fairly local to the device. The humidity within one foot of the device is very good according to my hygrometer. The humidifier's fan sucks this air back into itself repeatedly. By placing another fan to the side of the Venta to provide room circulating air current you can get an additional 3-5% humidity 5-7 feet away from the device (like where you're head is in bed). Of course now you've got another source of noise in the bedroom.
To compensate for the gear noise and the dirt problems I've tried adding all kinds of things to the water that might act as either a cleaner or a lubricant or both. I've tried double quantities of the Venta additive, a variety of soaps, various aeromatic oils in quantities where the oil's lubricant properites might help. Really nothing is effective.
In the end I have to say that I'm most dissapointed by this machine's price. The unit is nothing more than a large hunk of plastic with fan on top of it. If it was made in China this unit would cost $39.95. But its made in Germany by a company that seems to be over charging far beyond what the added expense of German manufacturing and poor exchange rate would explain. Being German made I was expecting that the unit be better engineered. The machine is built well - nothing has broken in 3 years of constant operation. Its weaknesses are not structural. There are simple ways of eliminating the problems I've listed. Fan noise can be reduced by using a larger, slower moving fan with more and better bearings (something that should be expected in a $500 device). The gear mechanism that generates so much noise should be replaced with a non-contact device like a magnetic drive similar to high grade aquarium pumps. A top of the line magnetically driven pump costs 1/3 of what this Venta costs so magnetic mechanisms should easly have been considered for a $500 device. That these obvious techiques... or any others... are not employed on a device of this cost in the face of its inherent problems is criminal.
99% of the time I recommend spending the extra money (even if it's 5-10 times more) and getting a machine built the right way. This machine is not built the right way - it's just 5-10 times as expensive. I don't believe anyone is building a humidifier the right way at this time. Given this I would have to recommend one of the 4+ star devices for $50-70 - steam seems to be the best for avoiding white powder and bacteria. I've purchased two Honeywell HWM450 steam humidfiers for $55 each. Their ability to humidify is incredible. In the same bedroom with 50% humidity the Vental might get it up to 55%. The Honeywell can get it to 70% if you want and has digital controls for setting the exact humidy you want (although they don't work that well). Overall any shortcomings of the $55 Honeywell are not related to it's main function - humidifying. The same can't be said for the VENTA.
