I have a unique situation where my bedroom does not have any windows, but a large sliding glass door instead. This Frigidaire unit proved up for the challenge of keeping my room cool during this heat wave even despite my high end gaming pc pumping heat during rigorous gaming sessions. The app control comes in handy, during my drive home I can tell my android auto google assistant to turn on my AC and my room is cool when I get home ( can be regulated by a timer as well). The ionizer is a bonus, keeping the air cleaner which is better for my asthmatic cat.
