Hard water scale destroys appliances and plumbing from the inside. And even after you treat the water coming into your home, your drinking water still carries chlorine, lead, PFAS, fluoride, and nitrates — contaminants a whole house softener alone was never designed to remove. The NU Aqua Upgrade Bundle pairs salt-free whole house scale prevention with a tankless reverse osmosis drinking water system at your kitchen tap — giving you complete, two-stage water treatment without salt bags, without a bulky RO tank, and without two separate orders.
Installed at your main water line, this whole house water conditioner uses template-assisted crystallization (TAC) to convert hard water minerals into harmless micro-crystals that can't bond to pipes, water heaters, or fixtures. You get whole house scale prevention with zero salt, zero chemicals, zero backflushing, and zero electricity. Effective on both city water and well water.
Unlike traditional RO systems, the tankless RO in this bundle has no storage tank under your sink. Water is filtered on demand — when you open the tap, it flows immediately through multi-stage reverse osmosis filtration and out clean. Removes up to 99% of 1,000+ contaminants including lead, PFAS, chlorine, chloramines, fluoride, arsenic, nitrates, and heavy metals. No tank means no bulky footprint under the cabinet, no stagnant water sitting in a pressurized vessel, and faster, fresher output from the first glass.
The standard tankless RO system alone is one of the best under-sink water filters you can buy. But if your home has hard water — and most city water in the US does — the softener is what protects your investment. Hard water shortens the life of water heaters, dishwashers, washing machines, and the RO system itself. The Upgrade Bundle treats both problems at the source: scale prevention at the main line, and pure drinking water at the tap. Both systems ship together as one coordinated order so there's no waiting on two separate deliveries or scheduling two different installation windows.
Every Upgrade Bundle ships free to the Continental US and is backed by our 120-day money-back guarantee and a 3-year warranty. Our water quality team is available by phone and live chat if you have questions before you buy.

And that's on top of all the other benefits you get with NU Aqua systems, like...
Salt-based softeners use resin beads that attract calcium and magnesium that cause hard water. Those beads sit in a big tub and when the resin beads are filled with particles they release salt, which softens water. However, this process creates tons of waste water and require big bulky reservoirs to operate.
Salt-free softeners like the NU Aqua 4 Stage Softener use a special filter to crystalize and neutralize calcium and magnesium. Those minerals then go through your pipes to descale and soften water without any salt exchange or bulky setup. It creates no waste water, and instead of removing calcium and magnesium, they're rendered harmless and re-added to your water to boost its ability to help your body.
