• 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).
• Please note this is a compatible spare part and the manufactures’ names and part numbers have been used for reference purposes only. Waterspecialist is an independent brand.

• Turn Off Water Supply — Locate the water shut-off valve for your refrigerator and turn it off completely to prevent leaks during the filter change process.
• Remove Old Filter — Gently twist the old filter counter-clockwise (usually a quarter turn) to unlock it. Pull the filter straight down to remove it from the housing.
• Install New Filter — Remove the protective cap from the new filter. Align it with the housing and push it up, then twist clockwise a quarter turn until it locks into place.
• Flush System & Turn On Water — Turn the water supply back on. Dispense at least 2-3 gallons of water to flush the system and remove any air or loose carbon particles. Use the included stickers to mark the installation date.
