What does the air smell like?
------------------------------------------------
Mold
1)For starters, mold can be hard to see obviously.
Its from any or all of these possibilities:
a)High inside ambient humidity
b)Building structural leaks from the outside leaking in from roof, wall, or foundation/floor
c)Inside plumbing leaks
d)Leaky or improperly operating heat ans AC system
You pretty much need to do your own visual detective work .
-------------------------------------------
2) other smells causing respiratory issues:
a)carpeting smells or air / germ cleaning chemicals
b)hard floor cleaning chemicals/germ killers - anything in that category has a possibility of being bothersome
(One commercial floor cleaner where I work at really bothers me, but not the other employees, "Pine -sol" is NASTY, strong stuff).
