Inquiry (采购产品): testing air I notice a smell of some kind of emission at night primarily, when I turn the lights out in my room. How much would it cost to check the air? Are the self collection products that I could use to collect a sample of the air at night? It is very disturbing. While I only plan to stay in this building during the summer, it is unhealthy, I need to know, and move now. **** Hidden Message ***** Adelaide Smith 525 S.
