City water is generally treated for safety, but it can still contain chlorine/chloramines, sediment, hardness minerals, and trace contaminants. Well water is untreated and can vary month-to-month, often containing bacteria, iron, sediment, sulfur odors, and other natural contaminants. A whole-home system adds protection and consistent water quality for either source.

City water meets minimum standards, not optimal ones. Filtration improves taste, reduces chemicals like chlorine/chloramines, protects plumbing, and gives your home better water for drinking, bathing, and appliances.

Point-of-use filters only treat small amounts of drinking water. A whole-house system ensures every tap— including showers, laundry, dishwashers, and outdoor faucets — gets filtered, conditioned water.

Yes. Our systems use simplified, single-manifold designs that many homeowners install themselves. They can also be installed by any local plumber—no special certification required. Our US-based water experts are available 6 days a week to help with any questions.

Yes. Our systems can be removed and reinstalled at your new home if plumbing access is available.

Yes. Our NSF/ANSI 42 certified carbon filtration is designed to reduce chlorine, taste, and odor for both City and Well water.

Most sediment and carbon filters last 6–12 months depending on usage and water quality. UV lamps last 12 months under continuous operation.

Salt-free conditioners use TAC to prevent scale without removing minerals, salt, brine discharge, or slippery water. They require no maintenance and create no wastewater, making them ideal for low to medium hardness levels. Salt-based softeners remove hardness minerals using ion exchange. They require salt refills every 4–6 weeks and produce brine discharge, making them ideal for high hardness levels.

Salt-free systems use Template Assisted Crystallization (TAC) to condition water by preventing scale buildup without adding salt. Unlike a salt-based system that removes minerals like calcium and magnesium, the ESOFT system retains beneficial minerals, so minor evaporative deposits may still occur. There is no maintenance, no heavy salt bags, and no brine discharge. Salt-based systems are banned or restricted in some states and municipalities including parts of Arizona, California, Connecticut, Massachusetts, Michigan, Minnesota, New Mexico, Texas, and Wisconsin.

Well water varies greatly by location. The best first step is to have your water tested. Results will determine if you need an iron filter, softener, UV, reverse osmosis, or a combination. Order your Water Test or call our US-based water experts for guidance.

For City water, UV provides an added layer of protection against microbes. Even treated water systems can have boil-water advisories, main breaks, or contamination events. UV sterilizes 99.9% of bacteria and viruses. For Well water, we strongly recommend UV.

When installed correctly, Kind systems are designed to provide 12–15 GPM, which is enough to run up to 5 simultaneous showers and appliances with no noticeable pressure drop in 98% of US homes with up to 5 bathrooms.

Each system uses specific sediment and carbon filter sizes, plus TAC cartridges and UV lamps where applicable. Exact replacements are listed on every product page, and our Autoship program ensures the right items arrive on schedule.

Orders placed before 2 PM EST ship the same business day. Most customers receive their order within 1–5 business days.

All Kind systems include a limited lifetime warranty on tanks, a 7-year warranty on electronic components, and a 120-day satisfaction guarantee — return it for any reason.

We don’t send installers, but any plumber can install our systems. We can recommend one based on your location. Many customers choose DIY installation because our systems are designed to be straightforward.

Filtration components, media, carbon blocks, and TAC cartridges are made in the USA and Italy. UV chambers and electronics are sourced from Canada.

Standard whole-house filtration does not remove fluoride. Fluoride removal requires a point-of-use reverse osmosis system. You can purchase it here.

The most frequent issues include hardness (scale), iron and manganese (staining, metallic taste), sulfur (rotten-egg odor), sediment (cloudiness or clogged fixtures), and bacteria (potential health risks).
