At King Pure Water, we believe everyone deserves clean, safe drinking water—and reverse osmosis is one of the most effective ways to achieve just that. This compact drinking water system fits neatly under your kitchen sink and takes up very little space, making it a favorite for homes across Sevierville, Pigeon Forge, Gatlinburg, Morristown, Wears Valley, White Pine, Seymour, Newport, Dandridge, Cosby, Knoxville, and surrounding areas, and beyond.

Reverse osmosis filtration reduces impurities down to 0.0001 microns. That means it can remove carcinogens, heavy metals like lead, cadmium, mercury, and chromium, and harmful contaminants such as cryptosporidium, nitrates, VOCs, salts, dissolved solids, and unwanted tastes and odors. The result? The cleanest, freshest-tasting water—ideal for drinking, cooking, coffee, teas, juices, and more.

We also offer an optional alkaline filter upgrade, which adds beneficial minerals and raises the pH of your water. Drinking alkaline water may help support a more balanced internal environment and assist in fighting off illness by maintaining a positive pH level in the body.

What’s In Your Water? Let’s Find Out.

Our reverse osmosis systems use a powerful 5-stage purification process—just like those found in many professional bottled water facilities, but designed for your home:

1. Stage 1: Removes sediment, rust, dirt, and other solid particles.

2. Stage 2 & 3: Dual carbon filters remove chlorine to protect the membrane.

3. Stage 4: Water is pushed through a semi-permeable membrane that traps harmful contaminants, which are then flushed to the drain.

4. Stage 5: A final polishing filter eliminates any remaining tastes or odors, ensuring crisp, clean water with every pour.

We recommend changing the filters annually. The membrane is tested each year and replaced only when needed, so you get maximum efficiency and longevity from your system.
