Stage 1

Spin-Down Filter

100-micron filter captures larger sediment, sand and dirt

The clear cover is easily removed for total cleaning (No tools required), flow Capacity: up to 25 GPM

Eco-friendly: Washable and reusable. Manufactured using FDA approved materials

Made in USA

Why it matters:

Filters rust, sand, and provides clean water, as water reaches the next stage

100 Micron Spin-Down Filter

Pre-Filtration

Our 100-micron spin-down filter is used for pre-filtration in our water treatment systems. It captures sediment particles and larger debris down to 100-Micron.

Easy to Maintain

The spin-down filter is easy to maintain because it has a flushing mechanism. You can simply open a valve to flush out accumulated sediment without disassembling the filter housing.

No Replacements

Since the filter is reusable and can be flushed, it doesn’t require cartridge replacements. This self-cleaning feature significantly reduces maintenance time and costs.

Stage 2

Sediment Filter

Filters dirt, sand, rust and debris from entering your home

5-micron pleated design traps up to 95% of particulates

Oversized 20” filter ensures maximum capacity and maintains  strong flow (15 GPM)

Eco-friendly: Washable and reusable. Manufactured using  FDA approved materials

Replace every 6-12 months for best performance

Made in the USA

Why it matters:

Effectively captures dirt, sand, rust, and debris to deliver cleaner water as it moves to the next stage of carbon filtration.

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 3

AIO Iron Filter

Filters out Iron (rust/red staining), Manganese (black staining), and Sulfur (rotten egg smell) from your well water

Eliminates metallic taste from iron and manganese and the rotten-egg odor from sulfur

Removes dissolved iron before it oxidizes and leaves orange/red stains on sinks, tubs, clothes, and fixtures.

Metered control – Regenerates only when needed, saving water and extending media life

NSF/ ANSI - 61 (drinking water safety), 372 (lead free) certifications. Long service life, typically 7–10 years before needing replacement.

Tanks and Media made in the U.S.A.

Why it matters:

Solves three of the biggest well water problems — Iron, Manganese, and Sulfur odor — in a single, efficient, low-maintenance system

Katalox Light Filtration Media

Prevents staining

Our Iron filter is highly effective at removing Iron, which can cause reddish-brown stains on sinks, toilets, and laundry and removes manganese which causes black stains

Removes Odors

The filter removes hydrogen sulfide, which cause black stains and a rotten egg smell in your water. By oxidizing these contaminants, the filter removes them, resulting in better-tasting and odor-free water.

Metered Control

Our Iron Filter is automated, using a control valve to backwash and clean the system regularly. This makes them easy to maintain since the system can flush out oxidized particles on its own, keeping the filter media clean and effective.

Stage 4

Carbon Filter

Delivers cleaner, better-tasting, and clearer water to every faucet in your home

Targets chlorine, chloramine, VOCs, pesticides, herbicides and other contaminants.

See full list 155+ contaminant list

Replace media every 5 years or 600,000 gallons for best performance

All wetted parts are NSF/WQA approved

Tanks and Media made in the U.S.A.

Why it matters:

Enjoy crisp, clean water with fewer odors and better taste — straight from every tap. Better-than-bottled-water quality that’s also gentler on your skin and hair.

Carbon Media

NSF/ANSI 42 Certified for Chlorine Reduction

Our Granular Activated Carbon filter uses the most advanced whole house water filtration technology to protect against Chlorine, Chloramine, and other harmful chemicals commonly found in water, which also affect its taste and odor.

Effective Against VOCs and Chemical Contaminants

Using a process called adsorption, the carbon effectively reduces contaminants like Volatile Organic Compounds (VOCs), Total Trihalomethanes (THMs), and Haloacetic Acids (HAAs).
See full 155+ contaminant list.

Improves taste and smell, Great for your Skin and Hair

Removing contaminants improves the taste and odor of your water and provides better-than-bottled quality water from every faucet. Clean water is also great for your skin and hair.

Stage 5

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.

Q&A

FAQ

Can I trust my well water supply?

Unfortunately, private wells are non-treated water supplies and more susceptible to contaminants and bacteria. The best way to ensure clean tap water throughout your home is to keep pollutants out of the water before it enters your home in the first place. The level of contamination and bacteria can vary from month to month and impact the level of filtration that is required.

That’s why Kind recommends upgrading to the WS-7000UV — featuring the latest Ultra Violet (UV) purification for complete protection. This powerful final stage of treatment uses concentrated UV light to neutralize harmful microorganisms, including bacteria, viruses, and pathogens, without adding any chemicals to your water. When it comes to the quality of water you drink and bathe in every day, there can be no compromise.

What is the warranty?

Our systems come with a limited lifetime warranty on the tanks and 7 Year Warranty on the Electronic Heads, as well as a 120-day satisfaction guarantee, This means you can return it for any reason if you are not 100% Satisfied.

Can I use this system on Septic?

Yes, the WS-7000 can be used with septic. The discharge from the IMS filter and backwashing carbon filter will not disrupt the probiotic bacteria colonies that break down waste in your septic system.

Can this system be installed outside?

Yes, the system can be installed outside as long as the electrical components are protected from the weather. Operating temperature outside has to be between 39°F and 113°F.

What is the maintenance on the system?

The sediment filter is designed to be replaced once a year.
The carbon media should be replaced every 600,000 gallons of water or 5 years, whichever one comes first.
The Iron media will last 7 - 10 years depending on water quality.

How do I know which system to order?

You should always start with one of our Water Test. Testing the water will guarantee you are buying the correct system for your water quality problem.

The cost of your water test will be fully credited toward any system purchase.

Or call our team of water experts with any questions at (888) 614-5559.
