Filtration Soiling

Filtration Soiling

Do you have black lines forming under your doorways and around your baseboards? This is caused by “filtration soiling”, which is something that occurs over prolonged periods of time as air circulating throughout the house passes through the carpet and the contaminants in the air are deposited deep into the carpet pile. It really is happening continuously to all of the carpet in your house, but is most pronounced along baseboards, under doorways, and around furniture, as these are areas where airflow is restricted resulting in a higher concentration of these fine particles being drawn much deeper into the carpet pile. Filtration soiling is most easily seen in light color carpets.

Filtration soiling can be very difficult to fully clean. Depending on the extent of the soiling, with special chemicals, processes, and sufficient time and effort, we can generally achieve good results in removing the majority of filtration soiling. If you have noticeable filtration on your carpet, we will provide you a quote for the added cost of the service to clean it.

The best way to attack this kind of soiling is to prevent it in the first place. Regular vacuuming around baseboards, furniture, and under doorways, is the key. It should be done with an edging tool since most vacuums without the use of a tool don’t provide very good suction right at the corner where the carpet meets the baseboard. A good additional step after vacuuming is to wipe along the edge of the carpet with a clean damp towel. Performed regularly, this will significantly reduce the amount of filtration soiling that builds up.
