RKIN OnliSoft Pro Whole Home Filtration System

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, 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.

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.

Comes Install-Ready

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

RKIN whole house water systems are manufactured in the USA and are made to be installed easily without needing professional help. However, we do recommend hiring a plumber if you are not mechanically inclined.

Multi-Stage 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 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.

Zee Pro Sediment Filter

Designed to filter 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.

Onlisoft Salt-Free Water Softener

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.

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.

The tank arrived damaged. One of the tank appears to a manufacture defect and uneven. My plumber won't install it as he doesn't want to be reliable for it.

Hello, thank you for the review and photos. As shown on page 6 of the manual, the tank boot(base) can be adjusted by lifting and gently tapping the tank on the ground: https://docs.google.com/document/d/e/2PACX-1vQe3Rj6DY6z4JG5Ybo3s-WLyhT4q5IrwVMZW-8xKGWyw1hLKk3uYjcDlxTy85D9vy38o7bhi2lUMoNH/pub#h.by70sis6hf76 Hope this info helps.

Fantastic all around.

The whole house filter and softener is everything we were hoping it would be. We can drink water from any faucet and not be afraid the hard water on the island would damage our plumbing. Thank you for a fantastic product. We look forward to many years of care free use.
