If you search for a whole house water filter, you’re certaint to come across the SpringWell CF1. It’s got great customer reviews, but we all know how those can be suspect at best. The question remains: is it any good?

As an expert in the field, I’ve meticulously researched, consulted industry experts, engaged with real users, and even tested whole-house water filters myself to bring you an informed perspective of the leading water filters, including the SpringWell CF1. 

Whether you’re a meticulous homeowner or a first-time filter seeker, by the end of this SpringWell CF1 review, you’ll know if this system is the right filter for you.

Quick Verdict

For most city dwellers with an average of one to three bathrooms in their homes, the SpringWell CF1 is one of the best whole-house filtration systems available. With its advanced filtration technology, lifetime warranty, and minimal upkeep, it’s a practical investment for a consistent and healthy water supply.

The SpringWell CF range of whole-house water filters is available in three different models. The CF1 (for one-to-three-bathroom households) and the CF4 and CF+ (for four or more bathrooms and commercial use). 

  • Removes a wide range of contaminants common in city water, including lead.
  • Requires no electricity.
  • Long-lasting filter cartridges reduce replacement costs.
  • A lifetime warranty and six-month money-back guarantee ensure you get your money’s worth.
  • The CF1 has a higher up-front cost than other water filtration systems.
  • It doesn’t remove bacteria and viruses; for that you need an upgrade.
  • Costly upgrades can add up.

If you’re looking for a reliable and efficient whole-house water filter system, the SpringWell CF1 Whole House Water Filter is definitely worth considering. It may be more expensive than other options on the market, but the filter’s long life will ultimately reduce the cost of ownership.

Who Is the SpringWell CF1 For?

Finding the right whole-house water filter in a saturated market can be hectic. You have to find the perfect balance between the filter’s features, affordability, and your household’s needs.

The SpringWell CF1 is for you if…

  • You’re navigating the hustle and bustle of city life; the CF1 is tailored for urban water filtration, ensuring your tap water rises above the city’s standards for a healthier lifestyle.
  • You live in a one-to-three-bathroom apartment, condominium, or townhouse.
  • You don’t want a point-of-use system that will produce filtered water from one faucet but need clean water from all your faucets.
  • You’re willing to invest more in a quality system to unlock the benefits of whole-house water filtration.
  • You want to save money on frequent filter replacements — and time replacing them.

The CF1 won’t suit you if…

SpringWell CF1 Features Breakdown

While filtration technology and components are largely the same across brands and systems, each filtration system will have features that stand out. Here are some key features of the SpringWell CF1:

4-stage ActivFlo filter technology

Like I said, most filtration technology is the same. It’s the combination of technologies that can enhance filtration performance. SpringWell applies four stages of various filtration to get the best result for municipal water.

The sediment filter blocks out larger contaminants, extending the lifespan of the other filters and keeping your water free from sediment, sand, and other debris. It’s only rated for 5 microns, but thanks to city water treatment, you probably don’t need better than that anyway. 

KDF filter media targets heavy metals, such as lead and mercury, and inhibits the growth of bacteria and algae. This stage adds an extra layer of protection for those concerned about microbial contaminants.

A catalytic carbon media removes chlorine, volatile organic compounds (VOCs), and other chemicals. This not only enhances the taste and odor of the water but also contributes to a significant reduction in potentially harmful substances.

A final high-capacity carbon filter removes any remaining contaminants from your water supply. 

Filter capacity and lifespan

The SpringWell CF1 Whole House Water Filter boasts a large filtration capacity and longevity. The pre-filter must be changed regularly within six to nine months, but the main filter media requires a replacement only once every 10 years (or equivalent of 1,000,000 gallons). 

This not only translates to cost savings for the user but also underscores the system’s commitment to environmental sustainability by minimizing the disposal of used filters.

Value for money

City water users benefit from a one-time investment that covers various aspects of water treatment, including filtration precision, durability, and user convenience. The low frequency of filter replacements, coupled with the system’s durability, translates to ongoing cost savings for the homeowner.

Ease of installation

The SpringWell CF1 Whole House Water Filter is easy to install and comes with an installation kit, and installation instructions are available online in PDF format.

The installation process is straightforward and can be completed in an hour or two if you’re adept at DIY plumbing projects. However, if working with pipes and wrenches is not your cup of tea, I strongly recommend you find a licensed plumber to do the job for you to avoid voiding the warranty.

Additional upgrades 

SpringWell offers several additional upgrades that can improve the system’s overall filtering capability. Particularly noteworthy is the UV filter, which utilizes ultraviolet light to deactivate bacteria, viruses, and other microorganisms, ensuring that the water delivered to your taps is not only softened and purified but also free from harmful pathogens.


SpringWell provides a robust warranty coverage that backs up the durability and performance of the system. The lifetime warranty on tanks and valves is pretty amazing; it ensures users have enduring protection against manufacturing defects or issues related to the core components of the filtration system. 

Additionally, the six-month money-back guarantee provides users with an extra layer of assurance. During this initial period, users can evaluate the system’s performance, and, if dissatisfied, return the product for a full refund.

However, the warranty does not cover damage caused by misuse, abuse, or improper installation. And you must foot the bill for shipping the unit back if you want to return it.

What I Like About the SpringWell CF1

Having extensively used and tested the SpringWell CF1 Whole House Water Filter, I can confidently say that it’s an exemplary whole-house water treatment system. The four-stage ActivFlo filter technology is great. I don’t want just one filtration technology; I want them all. The CF1 delivers. 

This comprehensive filtration process purifies water well, removing all odors and a wide spectrum of impurities, including sediment and chlorine. After prolonged use, the impact on water taste and overall quality is unmistakable; it’s noticeably cleaner and safer.

I love that I don’t need to buy refrigerator filters or under-sink water filters just to have clean drinking water. With this SpringWell water filtration system, my family can enjoy purified water from any faucet in the house. I also don’t need to carry bottled water to the office anymore.

The long-lasting filters are another commendable aspect, but the lifetime warranty coverage is what’s best about SpringWell. Many filters can do the job they say they’ll do, but few come with a lifetime warranty.

What You Might Not Like About the SpringWell CF1 

While my experience with the SpringWell CF1 has been overwhelmingly positive, it’s fair to acknowledge a few minor drawbacks. The first is its higher up-front cost compared to other brands on the market. However, this is offset by its long filter lifespan and enviable warranty, and it’s not as if other brands are giving whole-house filters away for free.

Additionally, if you’re unfamiliar with DIY plumbing projects, the SpringWell CF1 may require professional installation, which can add to the initial cost of the system. However, this whole-house water filter system is easy to maintain and requires minimal upkeep to ensure that it continues to provide reliable water filtration for your home.

Lastly, while the optional reverse osmosis and UV filter upgrades are a welcomed addition, they are quite expensive.


This section outlines my step-by-step research into the SpringWell CF1 Whole House Water Filter System.

Step 1: A list of all SpringWell water filtration systems

To get started, I needed to determine how many whole-house water filters are listed in the company’s online inventory. SpringWell has three systems in their city water filters section, the SpringWell CF1 Whole House Water Filtration System, the Whole House Cartridge System, and the Lead and Cyst Filter System

The SpringWell CF1 has the longest filtration media lifespan (10) of the three and offers more value for money compared to the cheaper cartridge filter system, which needs annual filter replacements. It made more sense to go with the CF1.

Step 2: Product analysis

To produce a factual review, I needed to ask important questions about this filter’s features, performance, and benefits, and also about whole-house water filtration systems in general:

  • Will a whole-house filter system cause you to lose water pressure?
  • How does catalytic carbon media remove organic contaminants in water?
  • How does the filtration media in the SpringWell CF1 compare with the competition?
  • How do disinfection by-products affect drinking water quality?
  • What is the average price for whole-house water filter systems?
  • Are there discounts available for SpringWell water filtration systems?
  • What is the average warranty of a whole-house water filter?
  • Do they all come with a sediment pre-filter?
  • What is the average frequency and cost of replacement filters? Are they easy to change?

Step 3: Online reviews

After I learned what to look for in a whole-house filter, it was time to find out other users’ opinions about its performance. I spent hours going through user reviews on websites like Consumer Affairs, Angi, the Better Business Bureau, and social media sites like Reddit, Facebook, and X (formerly Twitter). I took note of every sentiment, whether positive or negative.

Step 4: Interviews with real customers

Checking out online reviews is important, but as we all know, most manufacturers and retailers like to “spruce up” their reviews section just to drive up more sales for their products. I needed to find actual users who had firsthand experience with the SpringWell CF1.

The only sure method was to come up with a survey. So, with the help of a few friends, we organized a small cookout at a local superstore and handed out hotdogs and lemonade to anyone willing to share their experience with the SpringWell CF1 water filter. Despite it being more fun than I expected, I collected all the data I needed for my review.

To broaden the scope of my research, I also visited water equipment retailers and sought their input on this issue. I conducted Zooms with colleagues to learn what they and their customers thought of whole-house filters in general and the CF1 in particular.

Step 5: Interview with SpringWell

Next, I contacted SpringWell’s customer service department, and I pushed one of their representatives for answers on some of the negative feedback they received from disgruntled customers. The representative answered my questions calmly and was kind enough to walk me through the return and reimbursement process, as well as how the warranty works.

Step 6: Test drives

This is a crucial step of every review. To be an authority on this filter, I needed to actually test it out. Since my partner and I had already agreed that we needed a new whole-house filter anyway, I actually bought and installed the SpringWell CF1. I’m familiar with SpringWell’s warranty and I wouldn’t go with another brand, even though there are many good ones

When the shipment arrived, I made space in the pantry (where the main shutoff valve is located), installed the filter, and started the month-long testing process. I observed the quality of the filtered water, the cost savings (no more bottled water), and the easy functioning of the system.

Step 7: Ranking

After weeks of testing and data collection, I had all the information I needed to sit down and write this review. But first, I needed to organize this data on a spreadsheet based on the following factors:

  • Filtration media 
  • Lifespan of the pre-sediment filter
  • Contaminant removal
  • Filtration capacity
  • Ease of installation and maintenance
  • Filter replacement cost and ease
  • Price
  • Warranty and return policy


After extensive research and analysis, I highly recommend the SpringWell CF1 Whole House Water Filter for homeowners looking for a reliable and efficient water filtration system with an excellent warranty.

The filter technology provides genuinely purified water free from sediment, chlorine, bad odors, organic contaminants, and other impurities. Additionally, the SpringWell CF1 has a long filter lifespan of up to 1,000,000 gallons, which means you won’t have to replace the filter as often as some other water filtration systems.

The lifetime warranty is the cherry on top. It tells users that SpringWell is willing to stand behind its product. If you’re committed to elevating your water quality with advanced filtration technology, efficiency, and user-centric design, the SpringWell CF1 Whole House Water Filter is an investment that undoubtedly delivers.


If you want to know how the SpringWell CF1 stacks up against the competition, below are three alternative filtration systems for you to consider.

SpringWell Whole House Cartridge System

The SpringWell Whole House Cartridge System is a great alternative to the SpringWell CF1 for homeowners looking for a more affordable water filtration system. 

This system uses a 5-micron sediment filter and a 5-micron carbon-block filter to remove harmful contaminants from your home’s water supply. While it may not have the same comprehensive filtration process as the SpringWell CF1, it is a great option for homeowners on a budget.

Aquasana Whole House Water Filter System

The Aquasana Whole House Water Filter System is a great alternative to the SpringWell CF1 for homeowners looking for a more eco-friendly water filtration system, since there’s no draining or backwashing.

It will also maintain healthy minerals in your water. However, it doesn’t come with smart features like internet connectivity, and it won’t remove TDS (total dissolved solids).

US Water Systems Bodyguard Plus Chemical Filtration System

The US Water Systems Bodyguard Plus Chemical Filtration System is a great alternative to the SpringWell CF1 for homeowners looking for a more advanced water filtration system.

The Bodyguard lets you monitor your filter through a smart device. It’s also low-maintenance and easy to install, making it a great option for homeowners looking for a hassle-free water filtration system.
