What humidifier output level should I use?

Match output to room size: under 10 m2 use 100-200 ml/h, 10-20 m2 use 200-300 ml/h, and over 20 m2 use 300 ml/h or more. Too much causes condensation; too little under-humidifies.

Overview

A humidifier’s output (mist volume) should match your room size and target humidity. Small rooms (under 10 m²) need 100–200 ml/h; medium rooms (10–20 m²) need 200–300 ml/h; large rooms (over 20 m²) need 300 ml/h or more. Too much output over-humidifies and causes condensation; too little falls short.

Room Size	Recommended Output
Under 10 m²	100–200 ml/h
10–20 m²	200–300 ml/h
Over 20 m²	300 ml/h+
