Have an open parking space as close as possible to your front door. We clean our filters before every job, to maximize our vacuum. We also use a system that lets us know when we have removed as much water as possible, so we never overwet the carpet. It dries in 1 day. A house that is 72 degrees will dry half again as fast as a house that is 63 degrees.
Air holds very little water.
When the air has filled with moisture, the carpet stops drying. Get lots of air flow, and the carpet will dry faster. This can be accomplished by turning on the air exchange or opening windows. Even on a cold rainy day, the carpet will dry quickly if the house is kept warm, with just one window open a few inches on each end of the house. Fans pointed at the carpet will circulate the moist air away from the carpet, so dry air can replace it.
