Eliminate contaminants in the water that can be harmful to your body. By filtering chemicals such as chlorine and chloramine, you can avoid the drying effects of chemicals, promoting softer skin and healthier hair

The mineral build-up, or scale, can occur in plumbing and household appliances when your water is hard. Solid deposits of calcium carbonate can form when hard water is heated. This scale can reduce the life of appliances, raise the cost of heating your water and clog pipes. Long-term movement of hard water through a pipe results in scale buildup. This can gradually close up the pipe and lower your water pressure.

All our products come install-ready with minimal assembly required.

RKIN whole house water systems are manufactured in the USA and are made to be installed easily without needing professional help. However, we do recommend hiring a plumber if you are not mechanically inclined.

Stage 1 - KDF Media. Creates a bacteriostatic environment using copper and zinc alloy which helps with the removal of chlorine and heavy metals.

Stage 2 - Catalytic Activated Coconut Shell Carbon Bed. Designed to remove organic contaminants and disinfectant by-products such as chlorine and chloramines.

Stage 3 - EvenFlow Bed. Innovatively designed to maximize water treatment by substantially increasing contact time with the water filtration media.

Designed to filter out sand, silt, clay, and any other sediment.

This 5-micron sediment filter is the largest size available for maximum flow rates and longevity. It's 20 inches high and 4.5 inches wide.

High-Quality Filter Housing with Bacteriostatic Technology will provide years of pain-free filter replacements.

OnliSoft is a maintenance-free filtration media designed to prevent scale build-up by transforming hardness molecules into harmless minerals that no longer cling to household and appliance plumbing surfaces. This is accomplished without adding anything to the water, such as salt, acids, or any other chemicals.

How it works: The OnliSoft media naturally neutralizes hardness minerals through Seed Assisted Crystallization. This process of capturing, accumulating, and transforming the hardness minerals into inactive microscopic crystal particles occurs without introducing additional substances. These deactivated particles that are suspended in the water pass through and ultimately exit the entire household plumbing system.

The OnliSoft media is non-absorbent. It will work for a lifetime and doesn't require replacements or maintenance.
