Water filters are devices designed to remove impurities and contaminants from water, making it safer and more pleasant to drink. They can eliminate particles like dirt, chlorine, and bacteria, improving the taste and quality of the water. Common types of water filters include activated carbon filters, reverse osmosis systems, and ceramic filters. Using a water filter can help ensure access to clean drinking water, especially in areas where tap water may be contaminated. Many households use pitcher filters or faucet-mounted filters for convenience, while larger systems may be installed under the sink or throughout the home for comprehensive filtration.
