• Fast water flow, no leaks — Our mission is to supply refrigerator water filters that fit perfectly, impeccably engineered; this sets us apart from inferior models of replacement filters that can frequently result in water leakage problems. The microscopic pore sizes in our filter cartridges, made of superior materials, allow for smooth running, crisp, pure water.
• Waterdrop uses coconut shell carbon blocks supplied from Sri Lanka that have enlarged surface area and more micropores than inferior carbon blocks. The filter cartridge is far more effective in reducing levels of chlorine, dirt, sediment, rust, and a wide range of heavy metals tested by a third-party laboratory. In line with our high level of attention to detail, we have chosen a BPA-free and food-grade housing for the filter that exceeds the NSF/ANSI 372 certification for lead-free filtration.

• Prepare for Installation — Turn off the water supply to your refrigerator. Locate the existing water filter housing, typically at the top right of the refrigerator compartment. Remove any stickers or packaging from the new Waterdrop Plus WDP-F45 filter.
• Remove Old Filter — Gently twist the old filter counter-clockwise to unlock it. Pull it straight down or out, depending on your refrigerator model. Be prepared for a small amount of water to drain.
• Install New Filter — Align the new Waterdrop Plus WDP-F45 filter with the housing and push it up firmly. Twist it clockwise until it locks into place. Use the included installation stickers to mark the replacement date.
• Flush the System — Turn the water supply back on. Run approximately 3-5 gallons of water through the dispenser to flush the new filter and remove any air or loose carbon particles. Discard this initial water.
