About This Product

The Venta LW45 Original Humidifier humidifies dry room air in spaces up to 600 square feet (with standard 8-foot ceilings) using evaporative humidification. As a disk stack rotates in the water reservoir, clean water evaporates to humidify the air in your space. This cold evaporation process is recognized as the best humidification method. By implementing the principle of humidifying air for homes and offices without the use of filters, the Venta Humidifier is hygienic, simple to use, and easy to clean. Properly humidified air will also eliminate static electricity as well as work to preserve wooden furniture and musical instruments. Venta Humidifier offer the consistent performance of high-end German engineering; delivering optimal indoor air quality with properly humidified air to breathe. This 3-gallon capacity humidifier is powerful enough to work with indoor spaces of up to 600 square feet, ideal for living rooms, family rooms, or other large open rooms, and is designed to resist over-humidifying the interior.

yes it can.

I am considering this and the 2 gal. version. I am impressed with the great reviews of your products. However, several of the reviewers stated that they are effective in one room only. I have a closed-hot air-recirculating system. Wouldn't there be a whole-house benefit (to other parts of the house) if I use the 3 gal. unit (800 sq. ft. capacity) in a 400 sq. ft. room? aPPRECIATE YOUR RESPONSE.

HI, ok this is how it is, AIR FLOW, any unit, weather it be a dehumidifier, humidifier, heater, air purifier, etc. can only work in 1 room at a time unless their is air flow between the rooms, or you have pockets of stagnant which is to say non moving air that will not be affected by any of the units. you MUST have a cross flow of moving air between rooms for any unit to do more then 1 room.

Our Airwashers do work best in a closed space free of drafts. With that being said, the LW45 does cover up to 800 square feet based on standard 8-foot ceilings. If your entire space is 800 square feet or less, you would still benefit from the use of a Venta Airwasher, though you may not see optimal results.

    The Venta company website has different dimensions (17.8 x 11.8 x 13) than that shown at Home Depot (16.25 x 18.5 x 22). Are the Home Depot specs correct?

        How does it regulate the amount of humidity to prevent too much humidity?
        ByNov 23, 2018

        Answer This Question

        Our Airwashers utilize a natural humidification process called Cold Evaporation which ensures the unit maintains healthy humidity levels between 35% to 50%. Once the humidity in your space reaches the maximum healthy level, the fan will remain on, even though the air has absorbed the proper moisture. Venta Airwashers will not over-humidify the space even when the fan continues to run. Please feel free to reach out to us via email at info@venta-usa.com or by phone at 888-333-8218 for any additional inquires.

          It has speeds one, two, and three, depending on how much moisture you need in your home. We have it on speed two, and when we feel the air is humid enough, we turn it down to speed one.

            How do you use it (I assume add water?), how much water to refill, and how often?

            I add additive and water every two weeks after easy cleaning . I refill some water in the mornings and a little in the evenings depending on what speed I have it set to. It has 3 speeds.

              You take the top off and add water. I use a 2 gallon watering can. How much water it uses depends on what speed you use and how dry the air is. In very cold weather with the heat on, it runs on speed 2, 24/7 and needs to be filled almost every day. The unit should be emptied and rinsed out weekly. Additive should be put in when the water is changed, it's important to use it.

                          The best humidifier ever made!!
                          It’s awesome, I love the modifications from the model I had before which was at least 15-20 years old. You can totally remove the fan making cleaning a breeze. The parts are lighter and I hope they have the same longevity as the older version. Keeping the upper housing clean is important to keeping the fan itself from getting dirty. Keeping the machine clean also humidifies the air better. I love it. It was shipped a day after ordering and it arrived two days later. I do live in Illinois where the North American office is located.

                          Had the LW15 model for over four years - it still works great!. Time to upgrade to the LW45 , since my Dyson has failed and it was a year younger than the Venta and it cost so much more to maintained - acid packs , filters , evaporators .....and now the pump. Sorry Dyson - looks great on visuals , but bad on cost and longevity

                            I have one of these for my pet Iguana for her humidity as she is such a nice good natured pet. It is one of 3 I have for her, their is this unit, a Honeywell wick type unit and a zoomed fogger. This one has proven to be the most maintenance free, the Honeywell burns through wicks, really does not humidify better then this unit and it also can not clean the dust out of the air. The zoomed unit has been replaced 1 or 2 times in the same time I have has this unit due to total failure, and I have had to replace the fogger fan's so many times I have a box of replacement fans not to mention having to scrape off build up on the vibrating disk and it also can not suck the dust out of the air. SO out of 3 different types of humidifiers being this kind, wick type and misting, this one seems to be the best unit as it requires the least maintenance and does not need to be baby sit like the other 2 types of units. As their really is some thing to be said for how much of your time a humidifier should take up and constant maintenance really is not desirable. So if your sick of units that the wicks go dry in so you have to soak them every day and replace them too often, or misting types that the vibrating disk or fans go bad in all of the time, try one of these as you will not be disappointed.

                            This is wonderful if you have some nose bleeds when it's really cold in the winter ! I did not have but one this year compared to several as I usually do. It is easy to clean every two weeks & I only wished that Home Depot offered the most important thing you must buy Venta water treatment additive that you add to it every two weeks when you clean it out. The is a must to have ! Home Depot sells all the Venta products except for the Water Treatment Additive & I wished I didn't have to shop around for it else where ! That is the only down side. Please start stocking this Home Depot !

                            We have had various cold humidifiers in our 25 years, and our two Ventas are hands down are the best we’ve owned - we have had them for 15 and 12 years respectively. No recurring purchases of filters, and works great with our hard well water. Well worth the money !

                              It performs poorly even in a small room; the full tank has still not been evaporated over the course of a week at 29% humidity and a temperature of 22 °C. The water is purified by reverse osmosis.

                              Reasonably quiet operation.
                              This is my second LW45. I still operate my first one, but I needed a second one for my bedroom. It's quiet enough that I can sleep and the extra humidity prevents my nasal passages drying out and the problems that can cause.
