Some humidifiers need filters to function. Many routinely use heat to produce moisture by evaporation. These filters do not need antimicrobial agents to prevent microbial growth because the heat kills those pathogens. Cool evaporation units use wick-type filters. When the water vapor is pulled into the filter, a fan runs to create the evaporation. The wicks usually have an antimicrobial agent coated onto it to inhibit virus, bacteria, and mold development.

Mineral Absorption is where humidifier filters and cartridges trap minerals in the water that you add in its water tank reservoir. Humidifiers create a mist and minerals from ordinary tap water diffuse out to be a fine white dust on furniture and floors. By using distilled water, the dust is prevented from tap water minerals and lime scale. The water is about $1 per gallon and helps the life span of the humidifier and you do not have to do cleaning maintenance.

Humidifier filters clean the air fine particles such as pollen, dust, pet dander, and smoke that will stay in the water in the humidifier. Filters catch the particles before they are emitted with the evaporated water.
