The 10,000 BTU LG LW1025RSM cools rooms up to 450 sq. ft. (22" - 36"W x 13"H). This quiet, 3-in-1 window AC features 3 cooling and fan speeds and a 24-hour timer to create a cooling schedule. Its user-friendly digital control panel and included remote control make it easy to use, and it's equipped with a built-in dehumidifier that helps improve air quality in your space by pulling moisture from the air to reduce humidity. 4-way air deflection lets the flow of air be directed where it's needed most whether it's cooling, dehumidifying or just circulating air. The included filter helps reduce the number of large airborne particles in your space, and it's washable so when the check filter light comes on, you can remove it, wash it, and use it again. If there's a power outage, the auto restart feature will automatically turn your unit back on when power is restored. It also comes with easy-to-follow guided installation instructions so you can set up your new window AC in no time.
