Water filters help lower the contaminants in your drinking water. These filters come in all shapes and sizes—you might get a filter for your water pitcher, or get a built-in filter for your refrigerator. Faucet-mounted and built-in sink filters are also popular options. Pick and install a filter that best suits your household’s needs.^{[1]

Run your faucet for 2 minutes to get rid of contaminants. If you haven’t used your faucet in a few hours, the water just stays in your plumbing, which can lower the water quality. Before cooking with or drinking the tap water, run your faucet on a cold setting for 2 minutes first.^{[3]

Hot tap water may have bad substances in it. Over time, the metal sections of your boiler or hot water tank break down and leak into the water. The high temperature also dissolves these metals and substances into the water more quickly.^{[8]

Schedule an inspection at least once every 3 years. To be extra safe, don’t pour any strong chemicals or products down your sink or toilet, like old medicine, paint, grease, or used chemicals. Additionally, throw all your waste, like sanitary napkins, diapers, floss, and gum, in the trash, instead of down your sink or toilet.^{[9]
