Springwell CF1 Review: Functional Characteristics
Flex Bed
When compared to traditional filter media, SpringWell’s Flex bed has a significant performance and lifespan advantage due to its innovative design that eliminates channeling. SpringWell’s Flex bed is so effective that even under low-flow conditions, it produces the longest water-media contact time of any major whole-house system evaluated. Thus, the filtering is improved, and it is more reliable.
Bed frame made with KDF board
There are two primary filtration media in the CF range. The first is a KDF media, which is a copper-zinc alloy that can remove chlorine and other hazardous chemicals at a rate of up to 99.6 percent. Even if a municipality’s water supply has been approved by the Food and Drug Administration (FDA), it may still contain contaminants such as
- Chlorine
- Chloramine
- Haloacetic acids, and
- The so-called “forever chemicals” are PFAS and PFOS.
Thankfully, CF1 can reduce these contaminants to safe levels.
Bed of carbon catalysts
Catalytic carbon beds are the second type of filtration media used in CF series filters. These beds are optimized for removing organic contaminants that thrive in water and negatively impact the water’s flavor, odor, and visual appeal. In addition to herbicides and insecticides, this also includes gasses released by decomposing plants.
Filtering sediment down to 5 microns
The CF series, like all SpringWell whole-house filtration systems, includes a superior 0.5-micron filter. It helps keep water pure by eliminating minuscule particles of sand, silt, rust, grime, and other contaminants.

What Does Springwell Cf1 Filter? Contaminants Removal
A variety of contaminants, including
- Chlorine (up to 99.6%)
- Chloramine
- Pesticides
- Herbicides
- Rust
- Sediments
- PFOA
- PFAS
- Mercury, lead, unpleasant taste, odor, etc., are removed from the water by the SpringWell CF1 Whole House Water Filter.
This whole-house water filtration system is built to maximize its ability to remove impurities by maximizing the amount of time that the media filter is in contact with the water.
Filtration Stages
Four distinct filtration processes make the SpringWell CF1 Whole House Water Filter unique.
- The first stage is a KDF media filter, which is made of copper and zinc and eliminates chlorine and other common pollutants found in municipal water.
- In the second stage, this filtration system uses a catalytic carbon media filter to get rid of organic pollutants like chloramine, VOCs, pesticides, and so on.
- The third-stage flex bed is specially designed to maximize media filter contact time.
- Stage 4 includes a 5-micron sediment filter for the elimination of sediments, sand, silt, and other impurities.
Pro Tip:
Keep in mind that this filtering system won’t get rid of germs, so if you’re getting your drinking water from a well, you’ll want to invest in a UV filter as well.
Installation and Upkeep of SpringWell CF1
Although installing a whole-house water filter is not a simple task, the SpringWell CF1 whole-house water filter installation is much less complicated than the industry standard. It is due to the manufacturer’s excellent support materials, including detailed instructions, video tutorials, and even phone support.
To facilitate the process, you can also purchase an installation kit as an accessory. With the 24-inch click components included in the SpringWell Easy Installation Kit, you can quickly and easily join the pipes without resorting to elbows or glue.
The SpringWell CF1 whole-house water filter is easy to care for and won’t take up much of your time. Even though you only need to replace the primary filter once every ten years, you should change the pre-sediment filter twice a year, or every six to nine months.
Pro Tip:
Remember that you need to soak the media filter for 48 hours before you can begin using it, but the manufacturer’s video instructions teach you how to accomplish so.
The Flow Rate of SpringWell’s CF1
If you have up to three bathrooms in your home, you won’t have to worry about water pressure drops. This is because of the SpringWell CF1 whole house water filter’s 9 GPM flow rate.
The Springwell CF1 has a capacity of 12 GPM, making it suitable for homes with 4 to 6 bathrooms. Whereas the Springwell CF+ has a capacity of 20 GPM and is, therefore, suitable for homes with more than 7 bathrooms.
Because there are three models to choose from (9, 12, and 17 GPM), you can rest assured that your water pressure will not decrease after installing this system. This also prevents you from spending unnecessary money on a system with more capacity than you need.
Filtering Ability and Service Life of the Springwell CF1
The main filtering mechanism of the Springwell CF1 whole home water filter and a pre-sediment filter work together to get rid of sediments and other big pollutants in the water.
This is one of the greatest filtration systems available; the pre-sediment filter should be replaced every 6–9 months. However, the main filter has a huge longevity of 1,000,000 and should last for 10 years.
The total cost of ownership can be lower for a whole home water filter if it lasts for a long time. So this is something to think about even if the initial purchase price is higher.
Additionally, this is something to think about when comparing it to other options on the market. While it may be more expensive initially, in the long term you will save money because you won’t need to replace the filters as often.

Customer Support and Guarantee for the Springwell CF1
The tanks and valves on the Springwell CF1 whole-house water filter are covered by a lifetime warranty, making it the best option in this category.
SpringWell is so confident in its product that it offers a 6-month money-back guarantee, giving you plenty of time to see if it meets your needs.
One more thing in SpringWell’s favor is how helpful their phone support staff is, according to their customers.
SpringWell CF1 Accessories
The Springwell CF1 Whole House Water Filter is compatible with a variety of optional attachments to address a wide range of water quality concerns.
- The SpringWell UV Water Filter accessory is available for purchase and can eliminate 99.9 percent of germs and viruses from your water supply.
- The Clack Connectors Add-On is a simple installation kit designed to facilitate the setup of your Springwell CF1 whole-house water filter.

Frequently Asked Questions
Does SpringWell have NSF approval?
Installing your SpringWell System at the point where water enters your house, business, or restaurant effectively filters out various contaminants. The NSF/ANSI P473 standard for PFOA/PFOS and the NSF/ANSI 53 standard for lead and cyst reduction have both been met by this system. Furthermore, a third party has issued a certificate of approval for both standards.
How long do SpringWell CF1 water filters typically last?
The Carbon used in SpringWell Water purification systems is unique, and the company guarantees that it can immediately reduce chlorine and chloramine levels to below the MDL. For the first six years or one million gallons, whichever comes first, we guarantee performance.
Will a SpringWell CF1 water filter lose its effectiveness if it’s not used?
Simply put, water filters do not go bad after they have not been used. When stored dryly, water filters can last indefinitely. That’s the secret: water filters won’t function unless they’re exposed to moisture, so if you can keep them dry, you can use them whenever you like.
