5 STAGES OF ADVANCED FILTRATION
Salt-FREE, Non-Electric, No Need For Drain With Additional Plumbing.
Clears Out Existing Hardness Build Up.
COMBO CARBON FILTER
Stage 1 - KDF Media
Creates a bacteriostatic environment using copper and zinc alloy which helps with the removal of chlorine and heavy metals.
Stage 2 - Catalytic Activated Coconut Shell Carbon Bed
Designed to remove organic contaminants and disinfectant by-products such as chlorine and chloramines.
Stage 3 - EvenFlow Bed
Innovatively designed to maximize water treatment by substantially increasing contact time with the water filtration media.
STAGE 4 - 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.
STAGE 5 - 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.

United StatesGreat customer service! Great product! Yves F. Knows how customer service should be and did that throughout my questions and purchase. Even after the purchase his response was super fast. Thanks Yves, Iāll be buying more products! You canāt go wrong with RkIN
United StatesDad and I installed the system in about 4-5 hours. Most of the time was spent digging down into the ground to plumb the optional by-pass. Once the system was operational, mom noticed the difference in water right away. No more chlorine smell while in the shower and water looks so much clearer in the bathtub. Absolutely happy with this system.
United StatesWe moved into our new home here in Southern California and after 6 weeks we started to develop calcium rings in the toilets and scale in the showers. We decided to look at whole house systems from RKIN after having such great experience with our countertop ZIP filter. After using the whole house filter system were absolutely thrilled with the quality of the the water in our home.
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.
