Really loved our Julys. Got two, one for the bedroom and one for the living room. The filter is a really nice touch, and though I'm not entirely sure how much it helped, any amount of filtration is helpful in an old, dusty Queens apartment. (Please, someone, anyone explain to me why every single apartment in New York City generates untold amounts of dust?) Apart from the clean look, which alone would be enough to recommend it, the real star of the show was the app. It wasn't perfect, with bugs here and there, but being able to control the temperature so precisely, and to turn it on before you got home (or have the peace of mind that it was off when you left) is a true luxury. We ended up moving to a place with central air, but I honestly still miss the Julys.
Work on the app. It's buggy at times, and I would love for it to be integrated into Apple HomeKit. Consider other home cooling devices. I would love a July filtering fan, something like the Dyson PureCool.
