Unfortunately, almost all houses are closed
most
of the time because of the hot weather.
So, if your air conditioning system is
dirty, the dust and all the contaminants in
it keep circulating inside the house ( the
air conditioning system is a closed
system).
Bedside those contaminants, pet hair,
construction dust, pollen, etc. are part of
that circulation as well. Some of these
contaminants may be contributing to
allergies as the air is continuously
circulated through your system. |
