I just got back from the big local business that sells all kinds of heating and A/C devices and have our mini break A/C device for our study room. My Dad enjoys keeping the house a lot warmer than I do so I asked her if I can put a small device in our study room while I am here for many months going to see and she said of course I can. I like to keep our room at about 76F at night and she has been setting the plan to keep the place at 74F and I just can’t sleep when it is that warm. I have a small fan in our room however it just isn’t enough to cool me down so I am installing this small window device this week. I should be nice and cool in a few hours as it is truly easy to hook up and install. Once I get this thing set up I am going to put the temperature control on 72F and cool it down here immediately. My Dad keeps the house at 73F in the day and I am just dripping with sweat bullets as both of us speak, hence the current A/C device in our window. I don’t know if it comes with a HEPA filter, however I don’t truly care, I just want cold air in our room while I work and sleep. The rest of the house can be sizzling, however our room should be cool so I can work and sleep well. I suppose I will leave the small a/c in the window for next time when I come and visit.
