MAKE IT A COMBO WITH SALT-FREE OR SALT-BASED WATER SOFTENER
Why Use a Water Conditioner
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.
OnliSoft is a maintenance-free 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.
The OnliSoft media is non-absorbent and will work for a lifetime. This means that there are no replacements or maintenance required.
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.

Soft water not only delivers greater washing power, it reduces the amount of soap you need to use by up to 70%. In fact, the Bureau of Statistics found that between 17 and 20.8 cents of every dollar are spent on cleaning products. Soft water can reduce that bill by up to 65%. It can also eliminate extra rinse cycles and hot water. Plus using less detergent, household cleaners and chemicals is better for the environment.

United StatesWe started with the counter top water filter from RKIN and soon installed the whole house system. Big improvement in our water. Shipment on time but received broken part that RKIN replaced with overnight shipment. Installation was easy with step by step directions. RKIN was available by phone or e-mail to answer any questions or resolve any problems. I recommend this product.
United StatesInstalled this unit all by myself. Tank jackets are a nice touch to keep the tanks protected from the Florida sun.
This system doesn’t require any salt. Finally chlorine free water for showers and baths for grandkids. Our son in law installed it along with the undersink filter we got from this company. Highly recommend.
Had this system installed over a year ago. No problems at all. Also recently replaced our old undersink system with one from RKIN. Good
