Carpets have a long history, dating back to ancient Egyptians who created the first rugs, with the oldest surviving example being the Pazyryk Carpet from the 5th century B.C. Today, they are known for providing warmth, insulation, and safety from falls, while also having industrial significance, as the United States produces a massive amount of carpet in Dalton, Georgia. Modern carpets are often made from synthetic materials like nylon or from recycled plastic bottles, and can include up to 2,400 knots per square inch in high-quality handmade versions. 

Carpets act as air filters, trapping up to 80% of a home's indoor dust and allergens, but they can also harbor germs, which is why regular cleaning is essential. Deep cleaning is recommended every 6–18 months, and it can extend the carpet's life, improve air quality, and remove stains and bacteria. Addressing spills immediately and using proper blotting techniques are crucial for stain removal.
