What is a Water Based Air Purifier?

A water-based air purifier is a device that uses water instead of air filters to trap airborne pollutants. The use of water helps in avoiding any side effects while also ensuring that the air has enough humidity to alleviate allergy and asthma symptoms.

Water air purifiers can also be used for aromatherapy as they can mix the essential oils with water as it is agitated during the purification process.

Do Water Based Air Purifiers Work?

Yes, air purifiers that employ water to trap pollutants work. Water molecules have high adhesion (tendency to stick to other particles), according to the U.S. Geological Survey, and this allows them to stick to airborne contaminants when air is passed through it.

We see this phenomenon in practice when rain washes away the pollutants in the air, leaving behind fresher and cleaner air. Rain droplets stick to the pollutants in the air when they descend and bring the pollutants down with them.

These nifty air purifiers also double as oil diffusers and can act as humidifiers as well. These add value to your purchase and make these relatively inexpensive air-cleaning devices even more worthy of praise.

Read on to find out more about the best water based air purifiers available on the market and what advantages do these devices bring to your home.
