        Softer Skin & Healthier Hair

        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.

        Why use an RKIN water softener

        Why Use a Water Softener

        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.

        Why use an RKIN water softener and conditioner

        Prevent & Reverse Hardness Build-up

        Extend the life of your plumbing and household appliances by preventing and reversing scale build-up. OnliSoft Salt-Free water treatment system naturally neutralizes hardness minerals into inactive microscopic crystal particles without salt or any other harsh chemicals.

        RKIN Zee Pro Sediment Filter How it works

        Zee Pro Sediment Filter

        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.

        RKIN CBS DC20 Dual Carbon Filter Cartridges

        Certified Carbon Cartridge

        Activated carbon block filters for chlorine, chloramine, PFAS, taste, and odor reduction.

        Excellent chemical contaminant reduction, high adsorptive capacity, and efficiency.

        RKIN OnliSoft CBS Pro Filter How it works

        Onlisoft Salt-Free Water Softener

        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.

        Fantastic system, easy install, great water...

        For the first time in 30 years my wife has "poofy" hair (her term), and water tastes like spring water! We installed a whole house system with the pre-filter, two carbon filters and the conditioner and I couldn't be more pleased. The installation was straight forward and pretty easy, basically just installing a loop of the main feed into the house. Once the system was up and running I noticed an immediate improvement in the water quality. No salt or potassium, just fresh clean water. Bravo Rkin, bravo!
