For the best quality water and ice, replace it every 6 months or 500 gallons of water. Your refrigerator should remind you with the light indicator when its time to change its filter. The light indicator near the water dispenser would light up when the filter needs replacing. Twist off the old cartridge. Fully insert the new cartridge into the slot and twist to make sure it locks and seals.Why iSpring Water Systems? - Family owned Atlanta based company that lives on customers satisfaction - Earned the most restrictive industrial certification - WQA GOLD SEAL - We respect and love our customers!Lifetime PhoneEmail Support - In Atlanta, GA +1(678) 261-7611, 30-day Money Back, 1-year Satisfaction Guarantee, DIY video on YouTube, Spare parts.
