Cleaning your carpets at least twice a year is crucial for several reasons. First, carpets act like air filters, capturing dust, allergens, and pollutants. According to the Environmental Protection Agency (EPA), consistently dirty carpets can contribute to indoor air problems. In fact, areas with higher pollen levels, like Allen, can see more allergens clogging our carpets. Regular cleaning can reduce these allergens by about 50%, improving the air quality in your home.
