I have a similar monitor and if I never open a window for days it can get up to 2000 but I feel like I can keep it at ~600 just by always leaving a window slightly cracked open (not enough to noticeably cool the apartment). Using the stove or oven will definitely spike it though to scary levels! I've made a habit of keeping the windows fully open when I cook now.
