Waterdrop WD-10UB-B Under-Sink Water Filter with Matte Black Tap

Waterdrop WD-10UB-B is a non-electric under-sink filter system supplied with a dedicated matte black tap. Its activated-carbon filtration, twist-and-lock filter design and claimed 11,000-gallon capacity suit buyers seeking a separate filtered-water outlet, rather than TDS or hardness reduction.

At a glance

Manufacturer claims reduction of chlorine, taste and odour, and reports IAPMO testing against NSF/ANSI 42 and certification against NSF/ANSI 372.

Push-to-connect fittings and a twist-and-lock filter are intended to simplify fitting and cartridge replacement.
The manufacturer says installation is for a cold-water mains connection and gives a flow-rate claim at 60 psi.

What to know before buying

Listing details to confirm

The 11,000-gallon maximum service life or 12-month limit is stated for municipal water and may vary with water conditions. The manufacturer advises choosing an RO system for hardness or TDS reduction. The listed maximum temperature is 100 Degrees Fahrenheit, and the stated flow rate is at 60 psi. Although the listing claims reductions for PFAS, PFOA/PFOS and lead, its supplied certification details specifically describe NSF/ANSI 42 testing and NSF/ANSI 372 certification, so check the exact contaminant claims and applicable certification before buying.
