What is humidifier output?
Because room size recommendations are subjective and do not accurately reflect real-world environmental conditions, a much more accurate way to compare different humidifiers is with “moisture output per day” (also known simply as “output”). Humidifier output is often confused with water tank capacity (see below for an explanation of tank capacity). The output of any given humidifier refers to the maximum number of gallons of water the humidifier is capable of producing per 24 hour period. The output of a humidifier can easily be tested and verified, which makes it a very easy way to compare the effectiveness of various humidifiers, regardless of the manufacturer or even the type of humidifier. For example, a humidifier that has an output of 2.0 gallons per day will be capable of adding a maximum of 2.0 gallons of water to the room per 24 hours (assuming the humidifier is running constantly throughout the day, and is set to the highest fan speed or mist level). Humidifiers vary greatly
