Although it seems clear, air pollution isn't
necessarily a problem that just occurs outside. Even
within your house, you need to be concerned about
things like dust mites and filth tracked in from outside.
Your lungs may get irritated by indoor air pollution
from such sources, which can also aggravate allergies
and asthma. The problem is, if you use a regular vacuum
cleaner, you could only be "rearranging the dirt"; your
cleaner will collect part of the dust within the bag or
cyclone filter but let the rest pass right back into the
room. An air purifier may prove to be a wise purchase
for anybody who struggles with asthma or another
respiratory condition.
