That sounds about right. July was the hottest I've ever experienced. It was a month of heatwaves. It sucked lol. Not to mention, all the forest fire smoke, so you couldn't run AC without smoking yourself out. It was "great".
ACs have filters though? The filters are also replaceable, and sometimes you can get a better grade filter (advertised for people like hayfever sufferers). I would look into it before next summer...
