Traditionally, many companies produced humidifiers with filters. With the advances taking place in technology, manufacturers have now produced more efficient humidifiers that run without a filter.

Filterless humidifiers are rising in popularity over the years, and customers prefer having such a humidifier because it produces a much cleaner mist, lasts longer, and is also easy to maintain.

These incredible machines work by removing any substance present in the water through the use of electrostatic charge. This is different in humidifiers that use filters because they clear these substances using a filter and the filter requires regular cleaning and replacement.
