What is humidifier output?

Not to be confused with humidifier capacity, which is the amount of water the humidifier can hold at a time, humidifier output refers to the maximum amount of water the humidifier can add into the environment per day, and is the best way to compare the effectiveness of various humidifiers. Humidifiers can vary in output from 1 to 14 gallons per day (for example, a humidifier with an output of 10 gallons per day will be capable of producing 5 X more moisture than a humidifier with a 2 gallon output). Two humidifiers that each have an output of 4 gallons per day will be equally effective, regardless of the manufacturer's recommended room size, which is why humidifier output is the best way to compare different humidifiers and their relative effectiveness. If you are unsure which size humidifier is best for you, we have found that you will get the best results with the highest output humidifier possible that will fit in your room and budget.
