LW25 Comfort Plus Humidifier in Black - Filter-Free Evaporative Humidifier for Spaces up to 485 ft²

Before I start the review, I want to say be careful when handling the upper portion of this device. It has some thin plastic areas by the low water sensor. If you drop it, shatters easy. Happened to me. Had to glue it back in place.I decided to bite the bullet and buy the Venta LW25 after reading all the negative reviews. Then I found out about the Comfort Plus version when I registered for the warranty. Ended up ordering this one too. Most of the complaints in the negative reviews were taken care of with this new version. The manual says allow 7-10 days to get up to optimal humidity and guess what, they were correct. I have two cats so the house had a distinct smell. I noticed that on the first day of running this it had a fresh, almost like aired laundry smell. It was actually pleasant smelling in the house now. Not sure how well it handles dust but I am pleased with at least this level of purifying. The stabilizer liquid they have you put in to prevent mineral build-up and mold growth is a must. Makes cleaning so much easier. Read the manual guys! And follow the instructions. There wouldn't be a lot of the negative reviews. In my personal opinion, if you can afford the extra cost, the Comfort Plus version is worth getting over the basic model. It has a touch screen, gives you a humidity reading, and has an auto feature that automatically adjusts fan speed to the fluctuations in humidity. Not to mention, it also covers a much larger square footage. I have a bedroom with doors always open plus central heat and A/C and it has no issues keeping humidity at a comfortable level. Very pleased and would definitely recommend.

This is a fantastic humidifier. I spent weeks shopping for one, going over the different options of cool mist, warm mist, or wicking (evaporative). I wanted a good evaporative, because they are better, but they are few and far between these days. Having to continuously buy new wicks and having them get gross is annoying too. You don’t have to with the Airwasher! Just rinse it out and wipe off some residue every couple of weeks and use the additive they sell and you’re good to go! There is nothing else I’ve found like it.We got the largest most expensive one (LW45 comfort plus) to take care of most of the house. It says up to 600-700 square feet or whatever, but with the central air constantly moving air around it seems to get most of our 1200 sq ft house. The back rooms don’t get humidified as well, but it’s not bad. Still better than not having one. It’s probably about 5-8% lower on average further away from the unit in the back rooms but that’s still pretty damn good in my opinion considering I’m using it for more space than it’s rated.It works! It says right on the top panel the humidity %, and I was skeptical, even though I thought I could feel a difference. So I got another hygrometer to test and it is the same within a few % in the main rooms depending on where you measure. I have to fill it up about once a day running on level 2 or 3 constantly. It’s very quiet, and in addition to doing its job humidifying, it also doubles as an extra air purifier. No water spraying in the air or white deposits on stuff or needing to use distilled water. Tap water in and you’re good to go. When you dump it out to clean it you’ll see all the crap it picks up from the air. You only need to put in more additive every couple weeks when you clean it because it stays in solid form at the bottom even when the water runs out.It has three levels of operation, and an auto mode and sleep mode. And it will even alert you when it’s time to clean it. The company also offers a professional steam cleaning service you can get done every six months or a year for a charge. Haven’t tried it yet, but I might. They seem like a solid company. And it’s not some sketchy Chinese crap like so much Amazon stuff is.The only issue is the price. As it is mostly plastic, outside of some interior components with the fan and the simple touch screen, I can’t imagine how this thing deserves the $400+ price tag, but maybe the disks in the reservoir are kinda hard to produce. They are very specific in design. I’m guessing they can charge this much because no one else makes humidifiers like this and I wouldn’t be surprised if the disks and the design is proprietary/patented. It’s worth it though to get a humidifier and pseudo air purifier (pseudo because I don’t know how it would stack up against a higher volume HEPA filter) in one that works really well with simple upkeep.If you are worrying you won’t get what you pay for, you will. If you’re thinking this is too expensive, it is. I know that seems like a contradiction…it is. Haha. But seriously it’s a great humidifier. As long as you don’t need the money for rent and buy this instead, you will be happy. If you’re looking for a non-cheapo garbage humidifier that actually works, that doesn’t shoot up water into the air, and you’ve exhausted all the options and are still coming up short on exactly the right one, look no further. This is it. It just will cost you. You get what you pay for though.

This is the second one I am buying from this brand. The first one was 6 years ago and it still works as on day one. We use it for 8+ months per year non-stop (plain water, no additives). Helps with dry air, stuffy noses, etc. It is extremely quiet and a full tank lasts for couple of days. Easy to refill and no filters to change! They are expensive but I want to buy something once and use for a long time, so this is a great investment! We love them!

PROS: It is quiet. I keep it on high and I can barely hear it. On low it is almost inaudible. Nothing to buy again. No wicks. I don't use an additive. I empty it once every two weeks and rinse it out. No white dust. Since it is not ultrasonic, you don't have white dust on everything and aren't breathing in those mineral.CONS: Expensive. However not having wicks to buy, offsets the cost some. Wicks are expensive but it will have to run for 5 to 6 years to balance out the high cost. Not very effective. I only have to add about a gallon of water a day to it. My wick humidifier of about the same size uses about 2.5 gallons a day. So you would need twice as many of these to keep your house humid. Having to use a pitcher to fill it up is a pain. My other humidifiers have tanks that I take to the sink. They help keep the humidifier water at the proper level.If you have the money to buy several of these they would do a good job with no further expense.

the LW25 designed for 485 sq ft is working just fine in my small 650 sq ft studio. I have another brand as well that uses the wicking system and it works faster but I'll never need to replace the rotating evaporation system in this Venta like the other. In the first day alone my measured humidity went from 41% to 48% and evaporated a couple liters of of water.
