When choosing a good room humidifier, decide between cool and moist mist humidifier based on personal preference. Ultrasonic room humidifiers are preferred to evaporative humidifiers as they are considered safer. Select a humidifier with the right capacity, controlled moisture output, low operating noise and with a refilling convenience.
Decide between warm or cool mist or a dual unit depending on the convenience of the humidifier. Cool mist is preferred for its safety, especially when used in a room with children. Other humidifiers humidify and purify the air at the same time and can be expensive.
Select a humidifier based on the style and individual convenience. There are portable, personal, flow-through bypass and console styles. A personal or portable humidifier is convenient for a person with regular travelling needs. It is efficient for personal use and provides the required moisture, though it has limited coverage area.
Consider the capacity of the humidifier, since deficient or excess moisture can be problematic. Take measurements of the target room, and buy a humidifier for the correct room size. Excessive moisture results in condensation, leading to the growth of mildew and bacteria.
Consider the operating noise level and settings of a humidifier, especially when used in the bedroom. While humidifiers operate with some noise, choose a bedroom humidifier with night, silent or low settings.
