Water filtration system quickly filters water directly from your tap into four reusable, 16.9 oz. (500mL) BPA-free bottles at the same time. You can also filter water into only one, two or three bottles. System requires no plumbing or tools needed for setup. The filter is developed from innovative technology that allows the water to flow very quickly into the bottles - nearly as fast as your faucet flows. The filter lasts for 100 gallons. The bottles are dishwasher-safe (top-rack) and have a leakproof cap with carrying strap for grab-and-go convenience. Water filtration system includes one station with lid, one Filtrete Fast Flow Filter and four reusable bottles.
