50 GPD RO Membrane Reverse Osmosis System Water Filter

The 50 GPD RO Membrane Reverse Osmosis Water Filter for water that streams ultra-pure and whisper-clean. It strips TDS down to near-zero, yanking chlorine, fluoride, heavy metals, arsenic, nitrates, and thousands of dissolved solids. Coffee brews bold, ice freezes flawlessly, and every sip tastes like bottled perfection without the plastic. The universal 1812 housing drops into most under-sink RO systems, twist off the old membrane, slide the new one in, O-rings first, lock the cap. No tools, no mess, just 60 seconds to peak purity. Lab-tested to 98%+ rejection rate. Made to exacting standards. Delivers up to 50 gallons per day or 1–3 years before the swap.
