Faucet Water Filter

A faucet-mounted purifier has to be small, quick to install and cheap to keep running. The C-B2 is 140 × 110 × 63 mm and connects directly to the tap — no tank, no power, no plumbing.

One housing platform accepts four cartridge types: ultrafiltration, carbon block, a UF + CTO combination, or ceramic composite. That lets a brand sell one hardware design into several price points.

The base is 304 stainless steel with a transparent housing, so cartridge condition stays visible.
