The two major types of air purifier humidifier are discussed below:

1. The console air purifier humidifier – these are the largest of the lot, usually designed for floor use. They are housed in large cabinets and can control the air humidification in a number of rooms simultaneously. These machines work with the help of cloth or foam wicks which send the air through special filters. These filters ensure that the air released through the humidifier is clean and bacteria free. These filters need periodic changing so the efficiency of the air purifier is maintained.

2. The room air purifier humidifier – these are designed to specifically take care of the air of only one room. These are usually used on a table and are much smaller than the console types. These come in two major models – a warm mist humidifier and a cold mist dehumidifier. The warm humidifier does not use filters since they use heat to purify the air, and the other one uses regular filters.
