Which model & why you need an air purifier?
Venta air purifier using water as the filter.
The benefits of using water as filter is that the particles of water is small enough so that able to filter those small particle contaminants in the air.
However, the disadvantages are:-

- if you use water tap water, the chlorine in the tap water may cause 2nd pollution
- if you use filtered water, there is no chlorine and viruses may not be killed.
