Humidifier Cleaner

Cleaned machine well - will purchase again

Another high quality Venta item. I have two Venta Air Purifier Humidifiers in my home that are each just under 10 years old apiece. The humidifiers are simplistic to thoroughly clean & that helps with their longevity but once every season I use a bottle of this deep cleaner as well because it helps with motor parts & areas I can't reach to thoroughly clean. It isn't needed more than once a season though unless your units are running in very dirty air conditions. I've have no problems with my motors or any other parts since I began using this deep cleaning liquid as recommended. For normal running, I also add the Venta water conditioner because it helps make the water sheet over the rotating wheel for better humidity. Other brand water treatments can also be used to prevent calcification build up but I've stayed with the Venta brand (more expensive :() only because of the sheeting action it gives. This cleanser works beautifully & is a necessary part of my clean air/humidity maintenance routine. Can't go wrong with it.

It‘s imperative to use the cleaner at the end of the heating season. If the built up gummy residue is not removed, the humidifier will not function in the future. I speak from experience!

It got cold in Texas so dusted off the old Airwasher to keep the humidity up. Filled it up, ran it, immediately noticed a weird smell. Opened it up and apparently I didn't clean it well last winter cause it had this yellow cheesy mold (?) on the fins of the big wheel of discs/fins. Not entirely sure what it was but I'm gonna go with mold of some kind (it was old/dried at the time, the unit had been sitting dry all summer). Venta's own FAQ section says you can use a 1:1 water/vinegar solution as a substitute cleaner, so I did that and according to some youtube advice also dumped a couple spoonfuls of hydrogen peroxide in. Rotated the wheel through this and took an old toothbrush to it to brush the stuff off. The resulting water was naaaasty and had little chunks of whatever this is floating in it. Also left this to soak for a period of hours, periodically turning the wheel to get it all soaked. Also spot cleaned between the fins using q tips dipped in the solution. Dumped that out, and since it was so gross did *another* vinegar was/soak with no peroxide. Let the wheel soak in this once again. When all was said and done it looked more or less clean but still smelled funky. Finally got my Venta cleaner in and did that, initially smelled weird while the cleaner was in (might've just been the cleaner at that point). But all said and done, rinsed the cleaner off and I can run my unit again. Looks clean and doesn't smell weird. To me, this is analogous to the dishwasher: you wouldn't put a plate in with caked on dry spaghetti sauce, gotta get that off and *then* run it through the dishwasher. Maybe this stuff could've done it on its own but I doubt it. Initially when I saw the thing I was googling 'venta replacement parts', I wanted to throw out the wheel and buy a replacement. But they don't sell them. Glad I was able to get it sorted out, these units are too expensive. So, if you're (apparently) a slob like me, the above definitely works. If you've got the extra $25 to spare could try buying two and seeing if just the Venta cleaner on its own does it before going through all the vinegar like I did, if you do so please leave a review for posterity.

For those of you using the Airwasher Solution and wondering how to adequately clean your Venta every 2 weeks, I use Simple Green and warm water to soak the basin and water wheel, using Scotch Brite pads or a brush and rinse very well. To clean the fan blades and motor housing, I use a damp cloth sprayed with Simple Green and wipe all the goo away quickly. Then I refill the basin with clean water and add the Water Treatment Additive. I still use and recommend both Venta cleaning products as directed, but when the goo and those deposits build up, Simple Green cuts through them easily.

Clears the air beautifully. Leaving a fresh smell. I will be buying more.

I bought my LW25 Comfort Plus in October of 2020 and am writing this review in July of 2025. The unit is terrific. I use it to keep a large collection of Martin Acoustic Guitars in the 45 to 55% humidity level recommended by Martin for its expensive wooden guitars. Contrary to some reviews complaining about removing the top section (with the fan blades) to fill the reservoir with water, I find it easy. I keep two plastic milk containers in my guitar room closet. Lift the top section from the reservoir base and set it on its side, take the cap off the water-filled milk jug and pour. Put the fan section back on the base and press the on button. It's couldn't be simpler. I live in SW Colorado where we're lucky to hit to 20% humidity and I need to keep the humidifier set to 50% most of the time to get to 40% in an enclosed spot in the room. Yes, the machine measures the level at the machine. I use an inexpensive electronic device a few feet away to measure the level at the guitars. Not a problem at all.

We love our Venta humidifier, finally decided to clean it. This stuff works, but it's basically citric acid in a bottle. The price (like all Venta stuff) is absurd. However, you only need this occasionally, and it's always easier to go with the mfgr's own products. Still, that price....

We use this all winter in our Venta air cleaner/humidifier. Hard to find sometimes but effective to pull negative stuff from the air.

Hello reviews reader , the product works as expected, I was and still confused in how to use it , same people reviews says to run the product on the humidifier in open space which I did yesterday in my balcony for 3 hours and other people suggested to pour the bottle inside water in humidifier for two hours , but keep in mind the Venta company I instructions says to run the humidifier and cleaner for the whole run for once , results are great not more calcium attached to the wheel, I highly recommended it.... this a review since amazon or do not updated it or they don't want me to do it , this update is to confirm that after watch several YouTube videos where some people recommend the vinegar as a alternative solution to help to clean the calcium , is at to you but I will say it don't do it, use this solution from venta , left my venta air washer like new free of all the lines of calcium , I want to mention that not one has or is paying me to post this review , hope will help you .

Je l’utilise pour mon purificateur d’air et humidificateur Venta, très bon produit

Works fine. One bottle lasts one Canadian winter.

Used this year for the first time after a long winter of humidifying with well water. Followed instructions and cleanup required little more than a good rinsing. Will use this again next season for sure! Would definitely buy again.
