Your childhood days of drinking out of the hose are long over. These days, the taste of chlorine makes you sick, and rumors of lead, pesticides, and rust in the water make you particularly wary of drinking straight from the tap. When you want refreshing, great-tasting water, you know your best bet is a water filtration system from Costco. Sure, you could just buy pack after pack of bottled water, but you’d rather save the plastic and invest in a water purification system you can toss in the fridge or install under the sink. Costco has a large and varied selection of water filtration systems that are sure to bring you the best-tasting water possible. Shop by brand, capacity, or type, and select a water purification system that suits your family’s needs.
