Filtration soil

Carpet_filtration_soilFiltration soil may appear as dark or grayish lines on carpet along walls, in the crevices of stairways, through the gaps in plywood sub-floors and under doors. It is caused by airflow over and through carpet, allowing fine soils to settle on the surface. It is often caused by an improperly balanced ventilation system, when the volume of air entering a room exceeds the system’s capacity to remove air from the room. Excess air then seeks exit sources in gaps along walls and stairways. Prevent the airflow through carpet and carpet edges by sealing openings through the carpet and under doors and baseboards. Keeping the air in the area clean and using good filtration in your heating and cooling systems and vacuum cleaners can help. Filtration soils may require special cleaning treatment for effective removal. Contact a carpet-cleaning professional for assistance.
