Cheaper than Bottled, Richer than RO!

Sentry Wellness System is a 5-stage, under-sink, point-of-use water treatment system that works for all types of water. Not only does our zero-waste system filter out harmful toxins, but unlike Reverse Osmosis (RO) systems, it also enriches water with essential nutrients like calcium, magnesium, and increased pH for on-demand alkalinity. After an easy 15-minute installation, you can enjoy clean, healthy, great-tasting water straight from the tap.

Perfect for apartments, homes (including rentals), fridges, RVs, and more!
