Clean, great-tasting water straight from your kitchen tap. The BTECH Under-Sink Water Purifier connects to your cold-water line and filters on demand — removing the chlorine taste, sediment, bacteria and lead that municipal (NWC) water can carry, while keeping the natural minerals your body needs.
How it improves your water
Unlike reverse-osmosis systems, our ultrafiltration (UF) technology purifies your water without stripping out beneficial minerals like calcium and magnesium — so it comes out clean and still tastes natural. No wastewater, no electricity, and no bulky storage tank.
2-Stage Filtration
- Stage 1 — Carbon Block (5 micron): removes chlorine, sediment, bad taste & odour, and organic contaminants.
- Stage 2 — Ultrafiltration Membrane (0.01 micron): removes bacteria, cysts and fine particulates.
What it removes
Chlorine · Bacteria · Lead · Sediment · Cysts · Taste & odour compounds
Certified & safe
- NSF/ANSI 53 certified — proven lead reduction
- NSF/ANSI 372 — lead-free materials
Why ultrafiltration beats reverse osmosis
- ✅ Keeps beneficial minerals — water still tastes natural
- ✅ No wastewater — nothing wasted down the drain
- ✅ No electricity required
- ✅ No storage tank — filters fresh, on demand
