5-Micron Pleated Sediment Filter

95% of Particles Filtered

Designed to eliminate 95% of visible particulate matter and particles of dirt, sand, silt, clay, rust, and other debris, an essential first step that ensures clean, clear water reaches the next stage and extends the life of the carbon filter.

Strong 15 GPM (Gallons Per Minute) Flow

Our five layer 20” pleated sediment filter is twice the size of standard filters, delivering double the filtering capacity and filter life, with a pleated design that maintains high flow and minimal pressure drop. 5-micron filters down to 14 times smaller than a human hair.

Washable and Reusable

Made from durable polypropylene, this sediment filter can be washed and reused multiple times if you live in an area with heavy sediment.

Stage 2

ESOFT® Salt-Free Softening

Salt-free softener protects appliances and plumbing without salt and chemicals.

TAC (Template Assisted Crystallization) transforms minerals such as calcium and magnesium into harmless crystals (88% scale prevention)

No slimy feel of salt systems, no scale on fixtures or appliances. Keep minerals intact.

Zero maintenance, no heavy salt bags. No wastewater or brine discharge.

NSF/ ANSI - 61 (drinking water safety), 372 (lead free) certifications.

Made in the USA.

Why it matters:

Protects your plumbing from hard water scale while improving your appliance lifespan with zero maintenance, chemicals, salt or electricity.

ESOFT® Salt-Free Softener

Prevents Scale Build up

ESOFT® Salt-Free Technology uses a physical alteration process called Template Assisted Crystallization (TAC) to prevent hard water buildup. It converts 88%+ of scale-causing minerals like calcium and magnesium into tiny, harmless crystals that won’t stick to pipes or appliances, protecting your home without using salt or phosphates.

Removes Existing Scale

This salt-free water softener alternative not only prevents future scale buildup in plumbing but also helps descale existing hard water scale, a key advantage over traditional salt-based softeners, which only prevent new scale.

Zero Salt. No Maintenance.

An environmentally friendly and maintenance-free solution with no water waste, no electricity, no slippery feel, and no heavy and costly salt bags - ideal for people with health issues such as low sodium intake requirement.

Eco-Friendly, Zero Waste

Unlike conventional systems that chemically remove minerals, the eSoft system retains beneficial minerals and preserves your water’s natural hardness and optimal pH, though minor evaporative deposits may still occur. There is no waste water or brine discharge which has caused salt-based systems to be banned in several states.

Stage 3

UV Disinfection System

Powerful protection against invisible threats such as bacteria, viruses and other pathogens

High 15 GPM flow stainless steel chamber with high-grade quartz UV lamp

99.9% of bacteria and viruses sterilized

UV Disinfection System

NSF/ANSI 55 Certified for Disinfection and Microbial Safety

Utilizes chemical-free physical alteration with a strong quartz UV lamp to disinfect water by sterilizing 99.9% of bacteria including E.coli, viruses, and chlorine-resistant microorganisms like cryptosporidium and giardia—without changing taste or smell.

Chemical-Free Disinfection

Unlike city water treatment that relies on chemical disinfection with chlorine or chloramines, the Kind UV System uses UV light to sterilize microorganisms that chemicals can’t, offering a more complete level of protection.

Peace of Mind from Boil Water Notices

Ideal for added peace of mind during boil water alerts, which often result from E. coli detection or pressure drops in municipal systems that can allow pathogens to enter the water supply.

That is why Kind uses the latest Catalytic Activated Coconut Carbon Filtration technology with Ultra Violet (UV) giving you the piece-of-mind you deserve. When it comes to the Quality of water you drink and bathe in on a daily basis, there can be no compromise!tap. It reduces chlorine, sediment, and other impurities while protecting your plumbing and appliances from scale buildup. The UV system sterilizes pathogens such as bacteria and viruses, thereby offering an additional layer of protection for you and your loved ones.
