When it comes to safeguarding your family's health, nothing is more fundamental than the quality of the water you drink every day. With water contamination and mineral imbalances making headlines in 2025, having a trusted solution under your kitchen sink is more than a luxury—it's a necessity. That’s where the Sentry Under Sink System shines. But how does the Sentry under sink system work, and why is it quickly becoming a go-to choice for homes, apartments, and even on-the-go living? Let’s break down the technology, benefits, and daily impact of this innovative water treatment solution.
What Is the Sentry Under Sink System?
The Sentry Under Sink System, also known as the Sentry Wellness System, is a 5-stage, point-of-use water treatment solution designed for versatility and performance. Unlike traditional water filters, our system doesn’t just remove contaminants—it also enriches your water with essential minerals, boosting both taste and wellness. This system is ideal for apartments, homes, rentals, fridges, and RVs, offering compact power and zero-waste operation in one sleek package.
The Five-Stage Treatment Process Explained
Let’s dig into how the Sentry under sink system works step-by-step, ensuring every drop from your tap is clean, balanced, and delicious:
- Stage 1 & 2: Carbon Block Filter with Sediment Wrap — Removes chlorine, chloramines, volatile organic compounds (VOCs), and sediment down to 5 microns. This is your first defense against city water contaminants and debris.
- Stage 3: Scale Control CT Resin — Neutralizes both soft and hard scale, removes phosphates, chloride, and fluoride, and softens water without the need for salt. This stage helps protect your plumbing and appliances from scale buildup.
- Stage 4: Magnesium-Coated Catalytic Carbon — Targets PFAS, PFOS, PFCs, and pharmaceutical VOCs, while adding a “sweet” note to your water’s flavor profile.
- Stage 5: Trappsorb Media — Captures carbon dioxide, hydrogen sulfide, ammonia, phosphorous, and silica. It also boosts pH, alkalinity, magnesium, and calcium, ensuring your water is both clean and nourishing.
This unique five-stage process is what sets the Sentry under sink system apart from typical filters or even reverse osmosis units, which often strip water of vital minerals.
How Does the Sentry Under Sink System Work in Your Home?
Installing our under sink system is refreshingly simple. Most people can set it up in about 15 minutes with basic tools—no plumber required. The system connects to your cold-water line under the sink and dispenses treated water through its dedicated faucet or connects directly to your fridge line. Maintenance is a breeze, too: simply replace the filters once a year for optimal performance and taste.
Once installed, the Sentry under sink system continuously treats your tap water, providing a steady flow of mineral-enriched, toxin-free water for drinking, cooking, and more. There’s no need for bottled water or the wasteful byproducts of reverse osmosis systems—our technology is engineered for efficiency and sustainability.
The Wellness Difference: Health, Taste, and Sustainability
We designed the Sentry under sink system with your well-being in mind. Here’s what you can expect from daily use:
- Healthier Water: Enjoy water that’s free from common toxins like chlorine, lead, ammonia, PFAS, and more, while also benefiting from added calcium and magnesium for optimal hydration and wellness.
- Better Taste: Our five-stage process enhances the taste and texture of your water, making every glass crisp, smooth, and refreshing—perfect for everyone from picky kids to gourmet chefs.
