This is an excellent portable air conditioner. I have a 450 sq ft apartment in a very hot, humid area of Canada. We recently had temps that reached 45*C (113* F) and this unit kept my apartment at the perfect setting of 24*C (75* F). Also, I haven't had to drain it even once so the built in humidifier/evaporator works perfect. Overall, I would highly recommend this air conditioner. 5 ⭐️
