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.

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

Onlisoft Salt-Free Water Conditioner

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.

Does the RKIN OnliSoft Whole House Water Conditioning System require any maintenance?

The OnliSoft Whole House Water Conditioning System requires no maintenance and is a great money saver. It needs no electricity to operate and produces zero water waste. And since our water treatment system is salt-free, it doesn't require the yearly maintenance hassle and cost that is involved with standard salt softeners.

ZEE Pro Sediment Pre-filter will require replacement. Please below.
