Vacuuming may be something we do to tidy up before having guests in our home, but it also seems to be the solution to lessen pollutants in the air. But according to the American Lung Association, 99% of the particles we breathe pass right through a vacuum bag or filter. That's why we build every new home with a central vacuum system with the canister mounted in the garage. Any particles or pollutants that make it pass the vacuum canister in the garage are vented and exhausted outside.
