SALT-FREE WATER SOFTENER AND WELL WATER FILTER COMBO

Complete Protection

The RKIN Combo Water Treatment System uses a comprehensive approach to filtering water.
Filters iron, sulfur and manganese while preventing hardness build-up throughout your home.

Combo Well Filter Iron Sulfur Salt Free Water Softener Combo

Filters 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 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 chemicals such as hardness, iron, sulfur, and manganese, you can avoid the drying effects of chemicals, promoting softer skin and healthier hair.

Better Tasting Food & Water

With our whole house water treatment system, you can savor the purity in the kitchen.

Filtered water enhances not only the water that you drink but also the quality of the food that you eat. Upgrade your cooking by using cleaner and healthier filtered water.

Why Use a Water Softener

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.

Prevent and 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.

Comes Install-Ready

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.

ADVANCED WELL WATER TREATMENT

No Harsh Chemicals or Salt, Bluetooth and App enabled.
Filtered Water Made Easy.

MULTI-STAGE WELL WATER FILTER

RKIN Well Water Filter How it works

Stage 1 - Air Pocket
As water passes through the air pocket, iron, sulfur and manganese are oxidized. Additionally, dissolved oxygen is added to the water.

Stage 2 - Greensand Fusion
Media for efficient reduction of iron, manganese, & sulfur. The media bed removes the oxidized contaminants from the water.

Distribution System - Enpress® Vortech
Innovatively designed to provide increased backwash efficiency using less water and saving money.

SMART CONTROL VALVE

ZEE PRO SEDIMENT FILTER

Designed to protect the OnliSoft media from degrading performance while
filtering 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 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.
