Reduced Vacuuming Impacts Indoor Air Quality (IAQ)
Reducing vacuum frequencies hurts a carpet’s life and appearance, but these cuts can also adversely impact a facility’s indoor air quality. Most people don’t know that indoor air quality can also affect their health. The U.S. Environmental Protection Agency’s (EPA) studies of human exposure to air pollutants indicate that indoor air levels of many pollutants may be five times higher than outdoor levels. People spending 80 percent of their time inside have their health’s at a risk.

Tightly sealed buildings reduce ventilation rates to save energy; the use of synthetic building materials and furnishings, and the use of chemically formulated products have increased the potential for indoor air pollution. Indoor air quality can cause development of chronic lung diseases such as asthma. Allergies are an overreaction of the immune system to foreign substances causing infectious diseases caused by viruses and bacteria. Allergic reactions can range from mildly uncomfortable to life threatening, as in a severe asthma attack. The estimated number of people with asthma has risen more than 59 percent since 1970.

The largest source of indoor air pollution is from the common dust mite. Asthmatics are not allergic to living mites but to the airborne feces of mites and, to a much lesser extent, to dead mites.

A recent study concludes that carpets may benefit indoor air quality by acting as a filter for indoor air, trapping and holding dust mites, pollutants, and allergens such as pollen, pet dander and molds, which cause allergic diseases. The key to maintaining good indoor air quality in a school or office building is to clean this filter regularly, i.e., remove these pollutants through vacuuming.

The science shows regular vacuuming is important and necessary, not just to protect and maintain carpets appearance, but for hygienic reasons, as well.
