Indoor air is known to be two-to-five times more polluted than outdoor air. Health experts determine that this statistic will have a substantial impact on the health of both building occupants and cleaners. There are, in fact, many contributing factors to the indoor air contaminants, but it is no surprise that vacuum exhaust one of them. To minimize the impact of vacuums on the indoor air, manufacturers have introduced high-level filtration systems into these machines. These filtration systems will not only pick up debris from carpets but they will capture it as well, not allowing any exhaust back out to re-pollute the indoor environment. The most popular of filtration systems is HEPA, which is a multistage filtration system that can be found incorporated into many commercial cleaning vacuums. Vacuums featuring HEPA filtration can capture 99.9 percent of dust, pollen and other airborne particles. To maximize efficiencies of any vacuum filter, clean and change them regularly. And for vacuums that do not feature filtration systems, indoor air quality can be impacted by simply changing vacuum bags on a consistent basis.
