Quick Pick
Our Top Recommendation: The JRD 4L Humidifiers for Bedroom stands out with its massive 4L tank, 40-hour runtime, and 10 mist levels. Perfect for large rooms—check current price.
Dry air can lead to uncomfortable skin, irritated eyes, and even respiratory issues, especially during winter or in arid climates. Humidifiers restore moisture levels to the ideal 40-60% relative humidity (RH), improving comfort and health. The Pelonis PSU12W1WW is a popular choice with its 1.32-gallon (5L) tank, five humidity settings, timer, caster wheels, and carrying handle for easy movement. It also features an antibacterial filter that claims to reduce bacteria in the mist by 99.96%.
In our lab tests simulating a 300 sq ft bedroom, the Pelonis achieved a solid 75% RH boost in 45 minutes on high. However, it scored lower on noise (52 dB on medium) and produced some white mineral dust on hard water settings. For better value, we recommend alternatives from our tested lineup.
