Health professionals sometimes recommend that allergy and asthma patients remove rugs from their homes. But those recommendations are generally based on faulty assumptions. In fact, clean, dry, well-maintained rugs actually improve air quality.
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, surfaces covered in rugs or carpet trapped more particles so that walking disturbed fewer particles. Result: less dust in the breathing zone over carpeted floors.
