How Does The Kind E-1000 Whole House Water Filter Work?
Utilizing the latest in high-performance carbon filtration, the Kind is able to reduce hundreds of impurities commonly found in your municipal water supply. The Kind system also comes with a pleated 20” pre-sediment filter to remove silt and debris as water enters your home, which helps protect your system for the long term.
Its uniform pore structure increases water contact time with the carbon block to further increase the ability to address contaminants like:
- Chlorine
- Chloramine
- PFAS (PFOAS & PFOA)
- Arsenic
- Lead
Cities and municipalities often vary the amount of chemicals used to treat water throughout the year and that affects the longevity and effectiveness of a whole house filter [1]. But since the Kind is specifically designed for city water, you can be confident the system is delivering the purest water throughout your house no matter what the conditions.
After water passes through the system, you will notice a difference in your water quality immediately. However, if you have hard water issues, I would recommend checking out the E-3000 model which includes the salt-free softener.
The best part is you get all this without a drop in water pressure. The Kind has the capacity to support a house with up to six bathrooms, and has a huge max flow rate of up to 15 gallons per minute.
“It took only a couple of leisurely hours to install and within minutes there was a noticeable difference in water quality!”

There’s one more option to mention. If you are in an area with boil advisories or bacteria, the Kind system can also be paired with a UV purifier to sterilize microorganisms for the cleanest drinking water possible [2].

Simple Kind Water System Installation
When it comes to whole house water filters, the Kind installation is about as easy as it gets. There are no bulky tanks, and since it is cartridge-based, it takes up no floor space. We installed the Kind whole house filter and you can check out our install guide with detailed steps.
Installation is made simple with the easy Water-In Water-Out design that only requires two connections. Most DIY folks can complete the task in under 2 hours. Because it is not an invasive installation, the inline design means you can take it with you if you move. Furthermore, the Kind can be installed both inside and outside.
Straight out of the box it comes with all the components you need to wall mount and install the system. If you run into any issues, their customer support is top-notch and will walk you through it. Overall, you will save time and money on professional install costs with this system.
Filter Changes and Maintenance
When it’s time to change the filter, simply twist off the filter housing and swap the cartridges in a few minutes. The system comes with a spanner wrench to tighten the cartridge housing and loosen it in case it gets stuck.
The sediment pre-filter can be washed several times before replacement if your water has heavy sediment. It is recommended to replace the sediment filter and carbon filter once a year to ensure peak performance. If you get the added UV lamp, that also needs to be replaced annually. Compared to other cartridge options that need to be replaced every 3 – 6 months, this will add up to meaningful savings over time.
Although tank-based whole house filter systems do not require replacement for several years, the benefit of annual filter replacements is the Kind consistently operates at peak performance.
For added convenience, you can subscribe to Kind’s filter replacement program so new filters will show up automatically every 12 months. Not only can you save an extra 15% with this feature, but you won’t have to keep track of the filter’s life.
Warranty
All Kind systems are made using only NSF certified components right here in the USA . It is backed with an industry-leading lifetime warranty and a 120 day money-back satisfaction guarantee.
Even if you install the system and don’t like it for any reason within 120 days, you can send it back for a full refund!
