Value For Money

Size

I am a fan of Venta products for many years.  The  Water Treatment Additive is a must as it works very well making the cleaning of humidifiers quite easy.  That said it is disappointing that the product has gone from 1.8 fluid ounces to 17 fluid ounces and is considerably now more expensive for less product.

Great Product but…..

Venta

The old larger bottle had just one set of dosage marks, this one has two with no explanation of how they differ. Bring back the old bottle! This just creates.more.plastic waste and costs more per liter.

Confusing markings/more waste

The product is great, but now you only get about half of what you used to get for the same price. Still buying the product but not happy with the sneaky switch on sizing.

Shrinkflation!?

Product works as expected. I've used this for 20 years. Venta has gone to a small 17 oz container and charging the same exorbitant price...

Water Treatment Additive

I've been using this for years, but they recently came out with a new size.  Sounds better, right?  No, it's about half the size for the same amount of money.  A rip off

Smaller size, same money

While the treatment additive is effective and convenient, it's gotten quite expensive and should be sold in much larger containers with a bulk discount. Venta used to sell them in bottles at least twice as large, but it seems they discontinued any and all larger qualities and at the same time raised the until price. I have a large, dry house in a cold climate with radiant heat. That means I rely on humidification to make my home air livable. Venta is best way to do that, but I go through one of these bottles in less than a month when the old bottle used to last 3 months. Venta, release your loyal customers from shrinflation!!

Shrinkflation! What happened to the larger bottles?

The Venta water treatment additive is a terrific aspect of this system. It's like a self-cleaning solution.

When I add it every two weeks it minimizes the need to have the LW 45 sent back for Sonic cleaning. 

I do send the lw45 back once every 2 or 3 years instead of every year because of the Venta water treatment. Additive. 

I only wish they hadn't raised the price and simultaneously reduced the size of the bottle from something like 40 oz down to 16 oz.

Overpriced compared to last year

Water Treatment is expensive and hard to find.
Expensive. 
Expensive.

Expensive

I bought this a couple days ago.  I didn't realize Vena reduced the size by 50% but kept the price the same.  It was expensive before.  Now it's ridiculous

Now you get half as much for the same price

This is so expensive now that I regret buying Venta.  I have two large airwash machines and now I wish I could just throw them out.   This morning I had to buy one more humidifier for the family and because of the cost of this additive I went with a Carepod instead.  Stainless steel, no need for this additive which is such a money maker for Venta.  Also the service/parts department is ridiculous.  Get a website with an option to buy parts.  Venta is so behind on the times.

Won't Buy Venta Again
