SPRING-LIKE WATER FROM EVERY FAUCET

Complete Protection

The RKIN 5 Stage Water Treatment System uses a comprehensive approach to filtering water. It removes sediment, filters chemicals, and contaminants in your water supply while preventing hardness build-up throughout your home.

Filters Out Harmful Contaminants

Remove up to 99.6% of chlorine and other contaminants with our whole house water filter system. It has multiple lines of defense against harmful chemicals and pollutants, including:

Taste, Odor, Chlorine, Chloramine, Haloacetic Acids, MTBE & THM's, Herbicides, Pesticides, Sulfur, and many others.

 

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.

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.

 

Prevents Hardness Build-up

Extend the life of your plumbing and household appliances by preventing and reversing scale build-up. Our OnliSoft Salt-Free water treatment system removes harmful minerals, which cause scale and corrosion, without the use of harsh chemicals.

Comes Install-Ready

All our products come install-ready with minimal assembly required.

Manufactured in Florida, RKIN products are made to be installed easily without needing professional help. However, we do recommend hiring a plumber if you are not mechanically inclined.

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.

FREQUENTLY ASKED QUESTIONS

Does the RKIN OnliSoft Whole House Water Conditioning System add anything to the water?

No, it doesn't. The OnliSoft Whole House Water Conditioning System filters out impurities from your water, eliminating unwanted tastes and odors, without adding anything to your water. It provides clean, filtered water from every faucet of your home.

When I move, can I take my RKIN OnliSoft Whole House Water Conditioning System with me?

The RKIN easy-install design makes moving the system between houses a breeze. Just put the system into bypass mode, disconnect it, and take the system with you. The system can be re-installed in your new home with or without professional help.

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 Pre-filter and replacement media are available here.

Who installs my RKIN OnliSoft Water Conditioning System?

RKIN ships direct from factory, saving you over 60% of the standard retail cost. Our products' user-friendly design makes installation easy with or without professional help. However, if you're not mechanically-inclined, we do recommend hiring a plumber to help with installation. To download the RKIN OnliSoft Pro Manual, please click here.

What is OnliSoft?

OnliSoft is a maintenance-free filtration media designed to prevent scale build-up by transforming hard molecules into harmless minerals that no longer stick to the surfaces of your pipes and appliances. It accomplishes this without adding anything to the water, such as salt or chemicals

Here's how it works: The OnliSoft media attracts the hardness molecules present in your water and makes it cling to the surfaces of the media. Once these microscopic particles accumulate and reach a certain size, they seperate from the OnliSoft media and flow through the plumbing and appliances without sticking to them.

The OnliSoft media is non-absorbent and will work for a lifetime. This means that there are no replacements or maintenance required.

Another Quality Product From RKIN

We 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.

Filtered water through-out the house

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.
