EPA scientists have concluded that carpet can be beneficial in trapping and immobilizing potential allergy-causing particulates, preventing them from reentering the indoor air stream, if the carpet is properly cleaned and maintained. In fact clean, dry, well-maintained carpet actually improves air quality. Carpet holds allergen-causing substances tightly and, as a result, keeps allergens from becoming airborne, minimizing the level of allergens in the breathing zone. This translates to lower exposure potential. The allergens held by carpet’s filter-like effect may be removed by vacuuming, refreshing the filter-like properties of the carpet to allow more material to be removed from the air. Vacuuming mattresses, carpet, and upholstery once or twice a week removed allergens, including dust mite feces—a known source of allergen. It is important to use the proper type of vacuum to minimize resuspending allergens.

Professional Testing Labs studied the distribution of airborne dust associated with normal activities on hard and soft flooring surfaces. Their findings showed that walking on hard surfaces disturbed more particles. These particles became airborne and entered the breathing zone. In contrast, carpeted surfaces trapped more particles so that walking disturbed fewer particles. Result: less dust in the breathing zone over carpeted floors. A 1990 study in Sweden determined that levels of particulate contaminants, bacteria, and fungi in the indoor air in carpeted areas were always far below levels in the air above hard surface floors.

The PureStar combines 6 proven air-cleaning technologies into one unit. It has a HEPA filter, which is 99.97% effective at removing particles such as allergens. It also has an ionizer, which has been proven in government studies to enhance the performance of HEPA filters. Its UV light destroys micro-organisms such as dust mites & mold. It effectively removes dust, allergens, micro-organisms, cigarette smoke, odors, chemicals & bacteria.
