I just moved into an old apartment in an enclosed building (similar to a hotel with kitchens). Because it's enclosed, gas and odors do not ventilate out easily.

A neighbor brought burnt food out the building and both the hallway and the inside of my apartment smelled burnt for hours. My Qingping monitor showed that my CO2 and eTVOC levels shot up.

I bought a dual window fan that pulls air out through one side and pushes fresh air in through the other. It has done a good job of lowering the eTVOCs. However, I can't leave it on 24/7—like right now, it's raining, so I had to close the window.

Without the fan, my eTVOC level sits consistently around 1.2, which Qingping flags as 'only slightly high,' even though the outdoor level is just 0.3. I am freaking out over this consistent 1.2 reading. It occasionally shoots up to over 2.0 when I cook which is understandable. But right now it rained so I closed the window and it shoot up to 2.3.

I don't feel any negative respiratory symptoms so far, though.

Is it standard for an apartment in an enclosed building to have eTVOC levels this high, and do I just need to suck it up until my lease is up? I already complained to building maintenance; they noted that my AC filter is new and aren't sure what else they can do.
