Bottled water is expensive and a tank-style RO unit eats the whole under-sink cabinet. The Waterdrop G5P500A reverse osmosis system is tankless, filters down to 0.0001 μm through 8 stages, adds back calcium and magnesium for an alkaline taste, and fills a glass in seconds at 500 gallons per day. It is an open-box unit, priced well below what it costs new.
💡 Why You’ll Love It:
✅ 8-Stage Filtration: Reduces PFAS, chlorine, lead, fluoride, heavy metals and odours
✅ 0.0001 μm RO Membrane: Removes dissolved solids most pitcher filters miss
✅ Alkaline Remineralization: Adds Ca, Mg, Na and K back for a cleaner taste
✅ 500 GPD Tankless Flow: Fills a 6 oz cup in about 8 seconds, no tank to wait on
✅ 2:1 Pure-To-Drain Ratio: Wastes far less water than a conventional RO system
✅ Slim Under-Sink Design: Frees up to 70% of cabinet space compared to a tank unit
✅ Smart Faucet: Filter-life indicator on the dedicated tap
