Filter Out Iron, Sulfur, and Manganese

Does your water smell like rotten eggs? Do your sinks & toilets have orange staining? You and your family deserve the best quality water and expect that it be delivered at each faucet whenever needed.

RKIN Filter System is the answer to your problem with water to reduce Iron, Sulfur, and Manganese.

Softer Skin & Healthier Hair

Eliminate contaminants in the water that can be harmful to your body. By filtering out iron, sulfur, and manganese, you can avoid the negative effects of these elements, promoting softer skin and healthier hair.

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.

Independent laboratory testing

Test once and ensure you are purchasing the proper water system for your home.

A water test by a certified independent laboratory will help you determine exactly which water issues are present and identify the proper equipment needed to treat them. For most people, on well water Metals and Minerals test is sufficient. If you notice yellow coloration of water or staining, a tannins test is also required.

Access easy sampling, certified laboratories, and unbiased expert advice with SimpleLab. It's advanced water testing made easy. Our easy-to-read, professional water report provides a complete picture of your water quality.

We will even credit the water test cost towards your combo well water system purchase!

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.
