Final answer:
Water is already treated before reaching our homes, but filters installed in our houses provide an additional layer of protection to remove impurities and improve taste. Different types of filters target specific contaminants and provide a higher level of purification.
Step-by-step explanation:
Water is purified before it is supplied to our houses to remove contaminants and make it safe to drink. However, filters installed in our houses serve as an additional layer of protection to further remove impurities from the water.
Filters can remove smaller particles that may have bypassed the initial purification process, such as sediment, chlorine, and organic compounds. They can also improve the taste and odor of the water. Different types of filters, like activated carbon filters, reverse osmosis filters, or UV filters, target specific contaminants and provide a higher level of water purification.
So, while water is already treated before reaching our homes, having filters installed in our houses ensures that we have access to clean and safe drinking water.
