Users' feedback

Users quotes on Amazon.comPro: Actually it works! I see water in the tank disappears in 1-2 days and I also see a lot of dust + hairs in the tank, which means this unit, does its work. Just no way to see mist or how clean the air is since no way to identify the air cleanness. But for sure it works! Con: Too expensive!! $300 for this simple German mechanic system means the major portion of the price accounts for Loyalty + Motor. Even maintenance is very pricey! I didn't return mainly because this unit is also quiet when the slowest fan speed was selected - almost not sense the noise. "

Users quotes on Amazon.com60+ years of experience says Ventas is the best humidifiers I have been using humidifiers for over 60 years. I have a medical condition -- if I don't use humidifiers I get infections. It's that simple. So I use them faithfully. Overall these years, I have tried every kind of humidifier there is. The reality is that any machine that uses water the way a humidifier does takes some upkeep. When we had a house, we had a furnace humidifier -- the best money could buy. It was ineffective. So now I just rely on the Ventas. I prefer the smaller size as they are easier to handle overall. For about 1400-1500 square feet, I now have 5, though most folks could do with fewer I think. But the Venta air washers I have (started using in 2007) have been by far and away the best humidifiers and the easiest to maintain. They are clean, quiet, don't create mold or white dust, keep and your inside air much healthier. I have not been using them in the summer and the difference in the dirt on my furnace filter when I do not use them is significant. I rinse them out every 2 weeks and use the water additive. My thanks to the other Amazon reviewer who pointed out that the LW14 and 15 require only 1.75oz of additive -- not the 3.5 oz marked on the additive bottle. Once or twice a year, I clean them more thoroughly, first running them for a couple of hours with a mix of 3 cups white vinegar and 10 cups water. I take the fan out and clean the blades and clean the rest as best I can. There have been times I need to send them in for repair -- usually that loud squeaky noise they sometimes make. I suspect if you are handy you could fix them yourselves. In short, I highly recommend them. No humidifier is perfect, but these Ventas are absolutely the best I've found in 60+ years. Update: February 2018. I had been getting bad spring/summer colds each year so in 2017, I kept the Venta in my bedroom going all year, rather than just the winter months. No colds, no infections. These really work! "
