• Fresh-tasting water: The natural coconut shell carbon block absorbs more impurities. The Waterspecialist refrigerator filter provides you a unique filtration experience.
• Food-grade materials: We selected BPA-free and food-grade filter housing that passed NSF 372 certification for lead-free filtration. Waterspecialist is here to protect your water safety.
• Monthly install stickers: Expired replacement filters might cause an accumulation of pollutants and only achieve low-standard filtration performance. Therefore, Waterspecialist filters come with date labels that remind you to change it on time. Besides, the filter life is 6 months or 316 gallons (varies based on the water condition).

• Locate and Remove Old Filter — Open your refrigerator's water filter compartment. Twist the old filter counter-clockwise to unlock and remove it. Dispose of the old filter properly.
• Prepare and Insert New Filter — Remove the protective cap from the new Waterspecialist WS645A filter. Align it with the filter slot and twist clockwise until it locks securely into place. Ensure a snug fit to prevent leaks.
• Flush the New Filter — After installation, run approximately 2-3 gallons of water through the dispenser to flush the system. This removes any loose carbon particles and primes the filter for optimal performance.
• Label and Track Replacement — Use the included monthly install stickers to mark the installation date on the filter. Replace the filter every 6 months or 316 gallons for continued clean, fresh-tasting water.
