A Breakdown That Highlights Everything

Compatibility

Suitable for faucets with 1/2" or 3/8" FEMALE NPT thread. If you need a female threaded connector, please contact us before purchase.

Ultra-Long Service Life

Each under sink water filter system can last up to 36 months or 24,000 gallons when used with municipal water. For vacation, store filters in separate sealed plastic bags in your refrigerator to keep them fresh for 30 days.

Efficient Filtration

The Waterdrop Direct Connect Under Sink Water Filter System is tested by IAPMO against NSF/ANSI 42 for reducing chlorine, taste, and odor. It can remove VOCs (like chloroform), benzene, chlorobenzene, chloropicrin, and styrene. It also removes sediment, rust, and other large particles. Tested by a third-party laboratory against NSF/ANSI 53, it can reduce lead and PFAS, PFOA, and PFOS.

Solve Clogging Problem

Our upgraded filter now has a 20X increase in dirt adhesion area, enhancing filtration while reducing the risk of clogging.

Safe and Premium Materials

Made from BPA-free and lead-free materials, this filtration system is IAPMO certified against NSF/ANSI 372 Standard. For more details, search "WD-17UA" on the IAPMO official website.

Easy Installation

The system should be connected only to a cold water supply. Innovatively designed push-to-connect fittings make the installation process take less than 3 minutes. The twist-and-lock design allows you to replace the filter in just 3 seconds. The system includes a 3/8” hose with a direct connection that adapts to standard 3/8” feed water valves under US sinks. The 3/8”–1/2” convertor fitting helps connect the system to both 1/2” and 3/8” cold water lines and faucets.

Fast Flow Rate & Multiple Uses

The system provides a stable water flow rate of 0.75 gpm at 60 psi. It is perfect for household and commercial use—ideal for your kitchen, bathroom, RV, or office.

TDS and Mineral Retention

TDS is not a professional way to measure water quality. Essential minerals like calcium, potassium, sodium, and magnesium are important for your health. Our system removes harmful elements without affecting these essential minerals. Note: The activated carbon is made from natural coconut shells. Please confirm if you are allergic to it.

To ensure optimal performance and longevity, please follow the installation and storage instructions carefully.
