Filtration Line Problem?
Filtration soiling is a problem that affects many carpets. You can
recognize filtration lines easily. They show themselves as dark
lines around walls and underneath doors. I will explain how these
lines are formed and what can be done about them.

Filtration lines form when your air conditioning and heating
system blows air into your room. The air is blown into a room
effectively pressurizing it. The air must go somewhere so it goes
underneath walls and closed doors to equalize the rooms
pressure. The carpet along this area acts as a filter. It traps the
fine particles of dust and soot that are in the air. These fine
particles are difficult if not impossible to remove. If you have these
lines your first step is to call a professional carpet cleaner. They
will have the knowledge to get rid of the lines. You could try home
spotters but the residue left behind would probably cause the
lines to reappear later and they would probably be worse.

If you get rid of the lines or just want to prevent them, there are
some steps you can take. Filtration lines are worse if you burn
candles, incense or oil burners so use them sparingly. Also try to
leave doors to rooms open as much as possible. This gives the
air a place to go besides under your walls. Lastly you can use
quality air filters in your HVAC system that filter smaller dirt
particles. That's about all you can do. Unfortunately filtration lines
are just a part of owning carpet. We do offer a filtration line
service which costs $1.00 per foot and usually works quite well.
