Greenland 5.3Gal Humidifier for Large Rooms

The Greenland GLH20 humidifier uses a 5.2 Gal / 20 L water tank that delivers 25–40 hours of mist on a full tank. Its split design allows top-fill water addition and helps prevent leaks from the bottom. A filtration stone in the pump removes impurities before misting, and a UV-C light helps eliminate pollutants to keep the mist clean. You can set humidity between 45% and 90%, and spread mist with a 4-way nozzle and extension tubes. Choose from three mist levels and use the 12-hour timer for automatic shutoff. Control is via a full-function panel or remote, and the display shows ambient humidity and temperature. The unit features a low-noise fan and an auto-dimmed panel for quiet nights. Note: change water regularly; empty the water tank if you won’t use this unit for a long time. This machine requires pure water below 113℉ and use at room temperature between 41-104℉.

Designed for large rooms, it uses four atomizers and a powerful fan to deliver up to 1,000 ml of mist per hour, and it can cover up to 2,000 sq ft. It offers WiFi-enabled or non-WiFi variants to control humidity and schedule operations, with an auto mode that maintains ambient humidity between 40% and 70% and adjusts mist automatically. Ambient lighting includes six colors plus an auto-cycle mode, and an auto-memory function restores your last settings after power on (except the timer). A water-level light helps you see the tank level, and four caster wheels improve mobility. The filter element balls absorb impurities and should be replaced every six months.
