Question by LML L: What’s the difference between humidifiers with filters and the ones without filters?

Best answer:

Answer by Robert W
Traditional humidifiers use a filter that soaks up and saturates with water. A fan blows air through the filter allowing the water to evaporate into the air as it passed through the unit. The filter, meanwhile, traps any particles and pollutants that might be in the air before it leaves the machine and returns to the room.

A filter free humidifier doesn’t trap particles with a filter. It uses an electrostatic charge to charge the particles and passes the air over an oppositely charged grid. The opposite charges of the grid and the particles attract and the air escapes free of pollutants.

The obvious benefit is the cost savings from having to purchase replacement filters. But this also makes it much easier to maintain because the grid is easy to remove and clean. Simply remove the grid and wipe the build up off the grid with a cloth.

There are some health concerns with using a filter less humidifier because of the ozone that it releases into the air. However, there is no empirical evidence to support either side of the argument but is generally believed to be safe so long as manufacturer instructions are followed.
