Review on 🌬️ Whisper-Quiet Comfort Plus LW25 Airwasher Humidifier (White, Covers 485 Sq. Ft.) by Elizabeth White

I used the LW25 for 3 days in a 143 square meter room. ft. I've had mixed results with no more than 37% humidity for 3 days. I used 2 meters in different places in the room. It wasn't until I placed the meter next to one of the LW25's air vents that I was able to reach 41% humidity within half an hour. I need a constant level between 40% and 45%. I tested the device for 3 days in a room with the door closed. Later I placed the LW25 on a chair to see if the volume level in the room increased. At 1% it happened. I quickly sent it back and will buy the larger version.
