The LG can cool up to 450 square feet of space, or an 18- by 25-square foot space. It fits into most windows measuring 27-39-inches wide x 16-inches high.

If you have anAmazon Echo or aGoogle Nest Hub , you can continue to build up your smart home since it works with both Alexa and Google Assistant. Adjust temps and fan settings via voice controls, or use the handy remote in case you prefer to just press a button.
