Venta LW15 Original Humidifier Black - Filter-Free Evaporative Humidifier for Spaces up to 300 ft²

BEST!! Humidifier. (I encourage you to read please) no Humidifier will keep 50% humidity at day 1 2 3 4 UNLESS you already have 40%. lets start off with the "downside".... it can take days or weeks to catch up with Humidifying the room. If you have wood, furniture (maybe even the walls are wood) and already low humidity, it has to also humidify your house/room, your furniture, before it can keep water in the air. (this is actually just how nature works no downsides!) the unit is extremely easy to clean. it comes apart into 4 parts, the bottom, the drum (filter) the fan/motor, the top. CONSISTENCY means YOU ABSOLUTELY can leave it ON all day, it will stay at around 50% on its own. uses almost no electricity. you use your own tap water! it holds about 2.5 or 3 gallons. it doesn't care if you have hard water. but you must buy the VENTA ADDITIVE solution. no water = auto shut off = no worries. The only reason this would get a bad review is, they didn't do research, they skipped school, they didn't have patience. you absolutely CAN use warm water to jump start your room/area it's just not necessary. If its bright, get electrical tape. tape over the lights. Brightness =gone. if it's hard to clean, they probably didnt take it completely apart, never cleaned it for months, never bought the additive, etc. You do not need to clean it every day. maybe every 2 weeks. it helps tremendously with breathing. i had nasal surgery. this is a life savor. easy. very little maintenance. very simple design. light weight (without water obviously) I don't think it gets any more simple.

It has been over 5 years since my original purchase. I now own dozens of these either in my homes or in my laboratories or offices. I use the LW25's in guest rooms or smaller rooms and the LW45 (and now the new 6 series). I have to say the Venta is the best of all humidifiers, on all points. It has the most intelligent and easy disassembly of any humidifier I've owned, making cleaning it a simple breeze. It is quiet on high speed and pumps out a LOT of humidity. Every single component is EASILY replaceable and very inexpensive, direct from Venta Germany (with free shipping). No other humidifier on the market has every single component replaceable. NONE. Something breaks on ANY other humidifier...you must buy a whole new unit. These are pricey for what they offer and has rather simplistic technology... but they ARE effective and very quiet. If I was going to space on a long journey, you would want to take one of these. With the minimal amount of moving parts and components, this has a very low failure rate, and in the rare situation when it might fail, at least you're not at a total loss and can easily replace the failed component. However I have used mine 24/7/365 for over 5 years and JUST this year in 2019 I replaced a single motor in my LW25, for $30 direct from Venta. For me, dust levels around all of my robotic and computer equipment was a major focus of effectiveness. In my laboratories maintaining the precise humidity is critical for the specimens. I had purchased over 23 other humidifiers and none of them compared to the Venta. Some reviews complain about the grime or "white crust" in the humidifier after a few weeks. This is your poor quality hard water mixed with dust that the Venta has collected from cleaning your air. This is not some magical biological production from the Venta. Cmon people, simple science. You do not have to purchase the bacteriostatic agent from Venta (the cleaning fluid) although I recommend it because it is better for the plastic (less chemically abrasive) and reduces the amount of any algae or bacteria in the unit over time. If you are cheap you can always buy a $3 bag of pool shock (Calcium Hypochlorite) and mix half a TSP with 1 gallon of water. The $3 bag should make approximately 3500-4000 gallons, so as long as you store it properly, it will last you a lifetime. Apply 30ml of the Calcium Hypochlorite (pool shock) mixture to your (already filled with clean water) Venta. This will assist in bacterial reduction but it is more chemically abrasive than the Venta fluid. I have used this method in a couple of my laboratory units and this has not damaged them over several years, however if you dose too much of the Calcium Hypochlorite, the area will smell chlorinated like a pool/spa. Keeping the unit from any direct sunlight also helps tremendously in preventing any bacterial buildup. If you choose to not use anything at all, over time you will experience calcification on the inside, the dust being captured by the fans will eventually fall into the water reservoir and eventually the (over time) fishy smell of the algae and bacteria will attract fungus gnats. Real swampy ecosystem without cleaning. Just like any humidifier on the market. Except that this one is easily cleaned...and again, has all replaceable parts. For my home...With 1 LW45 Venta inside a 600sq ft room, there is a large difference in reduction of airborne dust and smells within 15 minutes. Sinuses feel much clearer with humidified air. This means no crusty boogers and a less likelihood of snoring. Specifically during Winter when the heater is running more, the humidity in the house plummets, causing dry nose and dry lips, the Venta units fix that. Simple science people. So for $400 you get cleaner air which is better for your skin and lungs and no crusty boogers or snoring from your spouse. I'd say that's $400 well spent. Only wish I'd have purchased the white one.

I tried very hard to like this given the cost and assertions made by the company about humidification and air purification. When this arrived 5 months ago and I opened up the packaging my immediate thought was seriously this cost this much?! I honestly have no idea how this is so expensive, but that's neither here nor there. I bought it lets hope it works. After the first night the water was indeed cloudy so clearly it was pulling in dust from the air that was getting filtered out so that's a positive. Unfortunately that's the only one. The container and the cylinder quickly become covered in a clear and orange slime after just a couple days use. I changed the water daily and would spend about 30 minutes each day cleaning the container (water reservoir) which is easy and the cylinder which is impossible. I would take the shower wand and put it on a jet setting using scalding hot water to blast away what was an endless supply of gunk every single day. Now if you want to go ahead and use the chemicals to clean this apparently it is pretty effective and virtually eliminates my complaint. However, when you read the warning label on the additive it states "Eye and Skin Irritant. Harmful if swallowed. Do not induce vomiting. Seek medical attention". Call me crazy, but the thought of taking something with this warning, pouring it into the airwasher and vaporizing it in a room where we sleep isn't something that I'm willing to do. It got to the point where I was pretty frustrated with this and I contacted the seller regarding a return. I was within the return window, but hadn't kept the packaging so I was told that there would be a 20% restocking fee for taking this back. I already spent 300 dollars on what turned out to be an oversized petri dish. I wasn't willing to spend 60 dollars just to get if off of my hands and get what ultimately ends up being a partial refund. So with that being the case, I wasn't willing to give up just yet. I continued to wash this on a daily basis only to see that the inner areas of the cylinder were getting more orange in color and an odor start to develop. I tried different ways to clean including vinegar and citric acid treatments (which doesn't thrill me either) which did help some, but over time it was slowly building up and just getting worse. From what I have been able to research, the chemical additive appears to be the only thing that seems to work, but again for me that just isn't an option. 5 months later I am finally waiving the white flag. Over the course of the past couple of weeks we have been waking up with soar throats and have had bad congestion. I pulled the plug and replaced it with a Honeywell HCM350B Germ Free Cool Mist Humidifier. Haven't had these issues since. Coincidence? I don't think so. As far as the Honeywell, so far so good. Granted it has a filter that needs to be replaced from time to time, but it's a small price to pay for performance and health. The nicest thing about it is how easily it comes apart and it couldn't be easier to clean (including the water reservoir where you can reach inside and clean it... every other humidifier I have ever owned with a separate removable water reservoir didn't have an opening large enough to do this). Bottom line is if you don't mind using additives in your humidifier then maybe this is as great as it's billing. For anyone that isn't comfortable with using additives riddled with warning labels then I'd recommend you look elsewhere

I really need this product. It has been bought from Germany and sent via the US which is the only way I can do this. I am really unhappy that it isn't working. It had very good reviews and is exactly what I am looking for.

Great hunidification, the air cleaning works amazing as the water is definately getting very dirty, and the reservoir size is good as it last a one full day. Living in Canada in Kelowna in winter, which is dry. Took the humidity of a 900 square foot space from 21% to 42% in about 4 weeks. The surrounding area takes time to absorb and humidify so it does take time to get to the specified humidity but it does work very well. Great product!

Buscando humidificadores, la mejor experiencia me la ha dado Venta. He tenido dos; uno que dejo de funcionar poco más de diez años, después de 12 años de uso y el que lo reemplazó, ahora ya con 10 años de servicio. Este es ahora el tercero, más pequeño para mi oficina. En pocas horas logró aumentar la humedad para hacerla más confortable.

The Venta LW45 I received has a defective power adapter cord. The fan cycles on and off about every half second which causes the fan turn in a slow jerky motion. The blue power light and numeric speed indicator also flash intermittently. Pressing the speed button doesn’t change anything and pressing the power button won’t shut off the unit. Fortunately, I also have a smaller Venta unit (LW25) that works well. I swapped fans and the problem persisted, so then I swapped the power adapter cord and the problem disappeared -- the LW45 worked perfectly. It appears that a defective power adapter was cycling the power which caused the jerky fan operation. If the vendor quickly sends me a replacement power adapter that works, I will revise my rating. Dec. 29, 2018 Update: After contacting Venta Customer Service, a replacement power adapter was promptly shipped to me via FedEx. This power adapter worked properly and now my Venta LW45 works as it should. It runs quietly and provides the needed humidification to prevent itchy dry skin and static shock during our cold dry winters in Western Canada.

I deeply regret purchasing the Venta Humidifier Air Washer from this seller. It was marketed as a high-quality, long-lasting product—a worthwhile investment. However, it failed completely in less than a month of use. What’s worse? The seller outright ignored my requests for help. Despite being only slightly beyond the 30-day return window, they refused to address the issue, leaving me with an expensive, non-functional product. No repairs, no exchange, no refund—just silence. This level of negligence is unacceptable. If you value your money and expect even basic customer service, avoid this seller at all costs. I will escalate this further until they provide a resolution. Buyers, beware: you are on your own once they have your money.
