LG LW1016ER 1000 BTU Window Air Conditioners are Energy Star Certified AC units that are compatible with True HEPA Filters. This compatibility isn\u2019t to be underestimated. There are a lot of air conditioners that don\u2019t have this compatibility, or at least don\u2019t have it explicitly stated. It\u2019s one of the reasons we\u2019ve deemed the LG a best through the wall air conditioner.\r\n\r\nWhy We Like It - LG 10000 BTU Air Conditioner\r\nThe LG 10000 BTU Air Conditioner is a great in-wall conditioner from a trusted electronics brand. It\u2019s powerful enough to cool a mid-sized room with ease and, if you don\u2019t like the way it looks inside the house, is also compatible with outdoor use. Just install it outside and feel the unit work its magic.\r\n\r\nPerformance\r\nThe LW1016ER LG AC Unit has a cooling power of 10,000 BTUs. Translated, this means the unit has a cooling area of about 400-450 sq ft. if you\u2019d prefer an air conditioner with some variance in BTU power, consider the Keystone Air Conditioner. The LG Air Conditioner can also remove 2.7 Pints Per Hour of moisture from the air which will feel like a God-send on humid summer days.\r\nEnergy Efficiency\r\nThe LG Air Conditioner has a CEER Rating of 12.0, which isn\u2019t the lowest we\u2019ve seen but still not bad. But what you\u2019re really wondering about is the Energy Star certification right? Don\u2019t worry, it has one. You can also check out the Friedrich Wall Air Conditioner for another great Energy Star certified unit. Unfortunately, LG website doesn\u2019t state if the unit is UL Listed or not. It would be a nice additional certification to have.\r\nFiltration\r\nIt\u2019s cumbersome to clean the filter on almost all in-wall air conditioners, and this Koldfront Air Conditioner is no different. Simply pull it out and clean it, and slide it back into place. Make sure you do this once a month and make sure you\u2019re giving it a light wash instead of just vacuuming it to clear it of all the larger particles. But what sets LG apart from the rest is that it works well with True HEPA filters so even the tiniest of particles don\u2019t stand a chance.\r\nDurability\r\nAt 72 pounds, the LG Air Conditioner sits firmly on the medium position of the lightweight to heavyweight line. If you are looking for a more lightweight model that can also cool a room size of 400-450 square feet, consider the KSTAT10-2C Keystone Air Conditioner. The LG\u2019s noise level isn\u2019t that bad for a window unit either. At 55dB it\u2019s slightly lower than human conversation, which ranks at 60dB.\r\nValue\r\nSome conveniences the LG Air Conditioner offers are a remote control so you can control the unit from a distance. This will be great in the summer months. It also offers three fan speeds, an auto-cooling feature, and a 24-hour programmable timer. It works on your schedule so you\u2019re not blowing air throughout the house and wasting energy while you\u2019re at work.\r\nLG 10000 BTU Air Conditioner Wrap Up\r\nThere\u2019s isn\u2019t a whole lot to complain about when it comes to the LG Air Conditioner. Its biggest drawback is the lack of UL certification. But the True HEPA filter should help mitigate this little snag somewhat. It\u2019s not exactly lightweight either, but it\u2019s not something you can\u2019t handle as long as you have a friend there to help you.
