Springwell CF1, CF4, CF+ Whole House Filter Reviews

You have lots of choices as you go about looking for a whole house filter that will enhance 100% of the water that comes into your home.

That’s why on Water Tech Advice, we have taken the time to review many of the best whole house filters to better help you with the shopping process when you are searching for a new one.

During that time, one series of whole house water filtration systems that stood out above all the rest were those made by Springwell Water.

I think that you would be doing yourself a disservice if you didn’t at least consider one of Springwell’s CF series whole house filters as part of your search process.

That’s also why I am going to take the time here to discuss in much more detail what there is to like about Springwell’s CF series whole house filters and the key features and benefits that come with these systems.

Springwell CF Series Whole House Filter Features

These features are what I like the most about the Springwell CF series whole house water filters (Note: these filters are also called media, whole home, and point of entry water filters):


Uses Two Proven Filter Media Types

The main filter media in this POE water filtration system is catalytic carbon which does a good job of reducing such harmful common household water contaminants as chlorine, chloramines, PFOAs, PFASs PFOSs, pesticides, herbicides, halo acetic acids, and more.

But before the water passing through the main filter tank reaches the catalytic carbon media, it must first go through the KDF-55 filter media.

This media type’s job is to enhance the chlorine removal process and it also helps to extend the useful life of the carbon filter media.  


The water that your family drinks after it has passed through the 4-stage filtration systems a Springwell CF-1 or other CF series whole house has, is water that will be 99.6% chlorine-free and look, smell, and taste great.

Included Sediment Filter


You don’t want large particle-sized contaminants causing problems with the media in your main filter system tank. That’s why all of the highest-rated water filtration manufacturers such as Springwell include a sediment filter with their systems.

The sediment filter that comes with a CF series water filtration system is 5-microns in size. That’s enough to eliminate such larger size impurities in water as sand, silt, clay, dirt, and many others.  

Allows for Very Good Water Flow

Each of the available Springwell CF series whole home filters impact your home’s water pressure very little after you set it up.

They are rated as follows in regards to water pressure:

  • CF1 – Allows for up to 9 gallons per minute (GPM) which is good enough for homes with 1 to 3 bathrooms.
  • CF4 – Allows for up to 12 gallons per minute (GPM) which is good enough for homes with 4 to 6 bathrooms.
  • CF+ – Allows for up to 20 gallons per minute (GPM) which is good enough for homes with 7+ bathrooms.

Many System Enhancing Add-Ons Available

One other thing that folks at Springwell know well is how to make a very good point of entry water filtration system even better. That is why they have several add-ons that can be purchased to work in conjunction with the CF series main filtration tank.

These are:

  • A salt-free water softener that will help prevent hard water minerals from forming problem causing limescale.
  • A UV disinfection chamber that will render the bacteria and other harmful microorganisms in the water that passes through it harmless.
  • A reverse osmosis filter that will help the system produce extremely pure drinking water.

Produces Over 1-Million Gallons of Enhanced Water  

Once you purchase a Springwell CF series water filter, you won’t have to worry about your purified water needs for many years to come.

That’s because each model is designed to filter more than 1,000,000 gallons of water. That’s a nice peace of mind to have once this system has been installed.

In all reality, that means you should easily get 5 to 10 years of use out of these whole house water filter systems before you have to worry about changing out their filter media.

Here are the good and bad points about using one of Springwell’s CF series whole house filters:  


  • Uses proven catalytic carbon & KDF filter media
  • Included 5-micron sediment prefilter
  • Many system enhancing add-ons available
  • Models available for homes with 1 to 7+ bathrooms
  • DIY installation compatible
  • Very low maintenance
  • Produces over 1-million gallons of enhanced water
  • Made with certified components
  • Lifetime guarantee on tank and valves
  • 6-month money-back guarantee
  • Free shipping


  • The initial purchase price is high
  • Not recommended for well water
  • Ineffective at bacteria removal


If you are a DIY type person when it comes to your purchases, then this whole home water filter will not disappoint you. That’s because even those with minor problem knowledge should be able to install with no problems.

It helps that Springwell has included everything right in the package to do the job except for some extra plumbing pipe and connectors.  

Included in the package are:

  • Carbon filter tank
  • 5-micron pre-filter
  • Tank head
  • Spanner wrench
  • Gaskets and lube
  • Wall mounting bracket
  • Hose bib assembly
  • 2-MNPT fittings
  • Bypass valve


Installation is not the only task associated with this whole-home filtration system that is very simple. It also takes very little to maintain the system once it’s in place and working.

About all you will have to do is replace the sediment filter every 6 to 9 months and somewhere down the line after many years of use, you will have to replace the media in the main filter tank.

How Do They Stack Up Against Competitors?

There is a reason why the CF series point of entry filter systems tops our list of the best whole house filters. That’s because they are so well made and make the best use of proven filter media types.

When you compare their features even with other quality whole home filter brands, the Springwell CF series consistently comes out ahead.

To me, it’s obvious that the folks at Springwell really put their many years of water filtration experience to use when designing this very highly rated series of point of entry water filters.

If you don’t believe me, glowing reviews on Springwell water filters like the CF-1 can be found all over the internet.

Summing Up My Thoughts on the Springwell CF POE Filter Systems

As you have read through this review, you have probably taken note of the many features that the Springwell CF-1 and other filters in the CF series offer.

It’s a long list for sure and that’s why this whole home water filtration system comes so highly rated by many.

When you factor in that Springwell Water includes free shipping with the purchase, a 6-month trial period where it can be returned, and a lifetime warranty on the major components such as the tank and valves, then this truly is a whole home filter worth taking a look at when you are shopping for one.

It is most certainly a recommended purchase by myself and the other experienced water treatment professionals here at Water Tech Advice.
