This appliance differs significantly from other air purifiers on the market. In fact, it is really more of a humidifier than an air purifier.

Unlike traditional air purifiers, this air humidifier and cleaner does not require changing filters. Instead, water is the filter. Water in the unit evaporates daily to humidify the air in a dry room. At the same time, dirt and dust particles adhere to the interior disk assembly and are collected in the lower housing as water evaporates. Operation requires a special additive that allows water to sheet off the rotating plastic discs.

No claims are made about the percentage of impurities this unit removes from the air. The residue left in the water chamber shows that it’s collecting dirt and allergens. Buyers report that the air smells fresher when the unit is running. But is the Venta is doing enough air purification to justify the price? Hard to say.

The Venta must be thoroughly cleaned every few weeks. However, the task is made more difficult by the many hard-to-clean crevices in the unit.

Some users say that this is a quiet, simple, and well-built humidifier. Others complain that the simplicity of design is a real drawback. For example, the unit has no water level indicator, no shut-off when the water dries out, and no humidistat to turn it on and off automatically. While some people find the humidity maintains at just the right level, others notice excessive dampness. Because the unit is a combination humidifier and air cleaner, you can’t run one function without the other.

If you’re looking for an air humidifier, this may be one to consider. However, if you suffer from allergies and you want the true benefits of cleaner air, you should buy an air purifier with a HEPA filter.

Here is what current owners have to say about the Venta Airwasher LW24 Air Humidifier and Purifier All-in-one:

Shelley Ureel: “This is my second Venta Airwasher I have purchased. They work as far as keeping the dust down. I keep it next to the bird cages to keep the feather dust down. The 10 year warranty is a plus… The only down side is having to fill it with water about every other day and then cleaning it about every 2 weeks.”
