The Sole purpose and vision which our project entitled to is clearly subjected to serve the health safety. Safety has
been a paramount at every level, even if we talk about safety of our health. We tend to think of air pollution as something that
happens outside but that's not always the case. Even inside our home, there are things like dust mites and dirt trodden in from
outdoors to worry about. Indoor air pollution from sources like this can irritate your lungs and contribute to allergies and
asthma. The trouble is, if you use an ordinary vacuum cleaner, you might simply be "rearranging the dirt": your cleaner will
trap some of the dust inside the bag or cyclone filter but let the rest pass straight back into the room. If you suffer from asthma
or another breathing difficulty, you may find a HEPA (sometimes defined as "high-efficiency particulate air," sometimes as
"high-energy particulate arresting") air purifier (or a vacuum with a HEPA filter) well worth the investment.
