Performance Features

Filtration Capabilities – How the System Works

The filter removes harmful contaminants from city water, like chlorine, chloramines, VOCs, pesticides, herbicides, insecticides, PFOA, PFAS, PFOS, odors, and taste. The system is 99% effective against all the contaminants found in city water.

The filter treats your water with the highest quality catalytic carbon and kinetic degradation fluxion (KDF) media. Filtration is a 4-stage process that ensures you get the highest quality water for your family. Its ActivFlo system ensures that you get the best quality water without any hassle.

  • Stage 1: Water moves through KDF media that removes chlorine and other harmful chemicals in the water supply.
  • Stage 2: It utilizes catalytic carbon media to remove organic compounds such as chlorine, chloramine, VOCs, pesticides, and herbicides from water.
  • Stage 3: Stage 3 increases contact time with filtration media to remove leftover contaminants and enhance water quality.
  • Stage 4: A 5-micron sediment filter removes sand, silt, clay, and other suspended particles before supplying water to your home.

before supplying water to your home.

Filtration Beds

The unit utilizes 3 different filtration beds to remove common contaminants in city water.

  • KDF Bed: The KDF bed is one of the two main filtration media in the filter. It removes up to 6% chlorine and other harmful chemicals in the water.
  • Catalytic Carbon Bed: The second of the two filtration media in the filter removes organic chemicals and compounds in city water. It also improves the aesthetic qualities of water, such as taste, smell, and color.
  • Flex Bed: The flex bed increases the filter’s life and performance by preventing channeling. It also increases water’s contact time with the filtration media to produce the best results, even when the water pressure is low.

Sediment Filtration

The unit has a separate 5-micron sediment filter that removes silt, clay, rust, dirt, and suspended particles from city water. City water is treated after it leaves the treatment center but catches sediment from water pipes, water tank, and your home’s plumbing system. Hence, installing a sediment filter with your city water is vital.

Flow Rate

SpringWell’s whole-house filter outshines other filters when it comes to flow rate. What’s the point of investing in a high-quality filter if the water pressure drops when showering, washing your car, or doing dishes?

The unit delivers water at a high flow rate (9-20 GPM). It is enabled by 1-inch connections that don’t slow down the natural flow rate of water.

Available Upgrades

The quality of municipal water varies from one city to another. Some places may require additional filtration systems to enhance water quality and make it fit for drinking and cooking. SpringWell lets you upgrade the unit with a UV water purification and RO drinking water system. UV protection is best for removing microorganisms like bacteria and viruses from water. An RO system is recommended for removing TDS from water.

Included Parts

The box includes the following components.

  • Sediment filter housing and a 5-micron sediment filter
  • O-ring for sediment filter housing
  • Mounting bracket
  • Spanner wrench
  • Hose bib assembly
  • Bypass valve
  • 1-inch MNPT fittings


All the tools required for installation come with the filter. You can install the filter yourself if you know how plumbing connections work. The hardest part is cutting water pipes and fitting the unit.

SpringWell has provided a detailed and easy-to-understand installation guide for homeowners. The CF+ variant has a slightly different installation process. You can read more about it here. Not everyone is handy with plumbing skills; hire a professional to do the installation for you. You can watch the video below for more details.

Maintenance & Warranty

The maintenance is minimal; the sediment filter must be changed every 6-9 months, depending on water quality and usage. The main filtration media requires replacement every 10 years or 1 million gallons of water.

A 7-year warranty covers the tanks. The filtration media, tanks, housings, valves, and in/out heads have a lifetime warranty under normal usage.

Frequently Asked Questions

Do I need to install any other filter with the SpringWell whole-house filter?

It depends. You may need a water softener if the water is hard or a UV system if it contains bacteria. Some people install a drinking water filter to be 100% sure about water quality. The best way to judge this is to get a water quality report from local authorities, and then you can decide which filter or filters you need.

Can I Install SpringWell CF filters outside?

Yes. You can install SpringWell’s filters outside, but it’s better not to. We recommend you go for inside installation because sunshine, rain, snow, or winds can damage the unit.

Does SpringWell Whole House CF Series Soften Hard Water?

No. It doesn’t soften hard water. You’ll need to install a separate water softener or buy SpringWell’s water filter & softener combo.
