This AC unit is off the charts. If it ever broke I would certainly buy another one. It cools my entire basement and I have 30 large aquariums in my basement because I breed fish. That says something right there. I have never seen so many air filter on a AC unit. It even comes with a carbon infused filter to keep air fresh. i HAVE NOT EVEN GOTTEN STARTED ON THE FACT THAT IT ALSO HAS A HEATER AND HUMIDIFIER...... It also has a drain  plug as it automatically pulls out humidity (just enough) while using the AC.  I have the largest window unit you can buy upstairs and yet this 14,000 BTU portable blows it right out the water. I could not be happier this unit should sell for 1k..
