SPRING-LIKE WATER FROM EVERY FAUCET

Complete Protection with Space-Saving Design

The CBS OnliSoft Water Treatment System provides a comprehensive approach to filtering your home water supply. It removes sediment, filters chemicals and contaminants in the water, and prevents hardness build-up throughout your home. It's space-effecient design takes up minimal space in your garage, leaving more room for your tools and equipment.

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.

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.

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.

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.

CBS WHOLE HOUSE WATER TREATEMENT SERIES

CBS stands for cartridge-based systems. CBS water filters are compact and convenient, making them ideal solutions for homes with 1 - 2 full time residents. Packed with powerful water filter media inside, cartridge-based water filters are effective at filtering the water for the whole house without sacrificing space in your home. Filter cartridges are low-maintenance and easy to replace.

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.

Long Lasting Optimum Performance

The Pre-Filter Zee Pro technology is designed to protect the OnliSoft Media from degrading performance over time.

Our high-performance whole house water system is built to perform at optimal levels for longer than the competing systems.

Easy Filter Replacements

High Quality Filter Housing with Microban technology will provide years of pain-free filter replacements.

Comes Install-Ready

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

Assembled 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.

4 STAGES OF ADVANCED FILTRATION

Sediment Filter Tank by RKIN

STAGE 1: PRE-FILTER ZEE PRO

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.

Carbon Water Tanks by RKIN

STAGES 2 & 3: COMBO CARBON FILTERS

Stages 2 and 3 - Coconut Shell Carbon
Designed & processed to remove organic contaminants, chlorine, and other disinfection byproducts. Click here to view Carbon Cartridge Certifications (system comes with 2 pcs).

Water Softener Tank by RKIN

STAGE 4: 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 in the stage 4 of the system 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.

Fantastic system, easy install, great water...

For the first time in 30 years my wife has "poofy" hair (her term), and water tastes like spring water! We installed a whole house system with the pre-filter, two carbon filters and the conditioner and I couldn't be more pleased. The installation was straight forward and pretty easy, basically just installing a loop of the main feed into the house. Once the system was up and running I noticed an immediate improvement in the water quality. No salt or potassium, just fresh clean water. Bravo Rkin, bravo!
