Product review (5 stars): Good for 6 months or 300 gallons
UKF8001 equivalent for KitchenAid . Made in USA and one of lowest prices on Amazon. Uses Coconut Shell particles for filtration. Good for 6 months or 300 gallons. You must run water dispenser for approximately 25 12 oz. glasses before excess particles are flushed out and water become clear. Before that I was skeptical because It seems long when you're doing it  especially compared to the expensive OEM filters I had previously used at double the price. Now water is clear and tastes great.
