Astrum Public Health offers a number of cleaning options to match any type of carpet. Carpets act as a filter for trapping dust, dirt, gases, animal hair, human hair and other soils. All carpet manufacturers agree on certain actions for carpet cleaning and increasing the lifespan of your carpet. Since 79% of soil in carpet is dry soil. At Astrum Public Health, we use the hot water extraction method with the most advanced equipment. Our recommended schedule is to clean your carpet every 12 months. It is important that your carpet is cleaning before it looks really dirty. Otherwise, it will become difficult to return the carpet to its original state. Dirt builds up in layers, and when a carpet looks dirty you are only seeing the dirt at the tips of the fibers. More dirt is hiding below the surface near the base of the pile, causing damage to the carpet. When a carpet is saturated with dirt, the soil has penetrated crevices and has become firmly lodged.
