If you live in that apt and it has central AC (most central ac houses/apt are almost sealed) your co2 ppm inside the apt should be around 600 to 1200 ppm depending of how many people live in it.
In my case those are the numbers in my house so I use it as my lung room so every time my co2 drops to 300 ppm my zone dampers open and my exhaust fan kicks in until it reach 500ppm by the time my dampers closed (it takes 90 secs) my ppm reach 700ppm.
sometimes if someone sleeps in that room it can reach 1200 easily.
I don’t use dehumidifiers or co2 bottles/generators and everything it’s controlled by growtronix except my mini split ac.
after the exhales bag, I modified my room to do this.
PS. When I visit my room the co2 ppm can reach 2500ppm, also I share this so growers with small grow room in their houses can take advantage of this.
Happy growing
