Have you noticed black lines in your carpet along your walls, steps or under doorways? This common issue is known as “Filtration Soiling” and can be very difficult to remove, especially when it has been a issue for some time. Imagine when your heat or AC comes on that your home is being pressurized in a sense. All of that pressurized air tries to escape your home and it does that in open pockets along the walls, stairs and under doorways. As the air passes through these openings in your home the carpet acts like a filter, catching all the indoor air pollutants in the fibers of the carpet making them look dirty or soiled. If you burn a lot of candles in your home which create soot, this problem will be even more evident. Addressing this issue early on is key to removal in many cases, but is not guaranteed. Regular cleanings will reduce the damage of filtration soiling and greatly improve indoor air quality. Give us a call today for your free, in home estimate.
