What does humidifier room size mean?

Humidifier room size is a manufacturer recommendation only, and is based on the maximum capabilities of the humidifier which most people are unable to use or take full advantage of. Based on customer feedback, we've learned that very few people run their humidifiers on the top speed setting 24 hours a day, as console humidifiers are powerful and noisy at top speed. If you are unsure which size humidifier is best for you, we have found that you will always get the best results with the highest output humidifier that will fit in your room and budget.

Based on how most people run their humidifiers, we've found the chart below to be a good starting point when considering a humidifier for your room size:
