SpringWell Water CF Whole House Water Filter Series – Key Features
First of all, what’s the difference between the SpringWell Water CF1, CF4 and CF+?
It’s their size and consequently the maximum amount of water they can filter at any given time:
- The CF1 whole house water filter delivers up to 9 gallons per minute (gpm) suited for homes with 1-3 full bathrooms.
- The CF4 delivers up to 12 gpm, enough for 4-6 bathrooms.
- The CF+ delivers up to 17 gpm for anything larger.
Regardless of which version you choose, this is what the filtration process looks like:
- Stage 1 is a sediment pre-filter. Rated at 5 microns, it traps any sand, dirt, etc. above that threshold to prevent the media in the large tank from clogging.
- At stage 2, a copper-zinc alloy (KDF) removes chlorine and heavy metals, and it inhibits the growth of microorganisms – think fouling.
- Next comes a catalytic carbon bed. You probably don’t know, but catalytic carbon is more sophisticated than regular activated carbon, meaning it reduces a larger range of contaminants. And it lasts longer. It’s the heart of each SpringWell whole house water filter system and tackles chlorine, chloramine, TTHMs, pesticides and other organic contaminants that could be lurking in your water. By the way, SpringWell Water guarantees that, for 1 million gallons or 6 years, chlorine and chloramine will be reduced below the minimum detection levels.
Min/max required water pressure: 25-80 psi.
CF Series Pros
If you’re handy with tools, you can install a SpringWell whole house water filter yourself. The same goes for system maintenance which is kept at a bare minimum.
What’s more, if you’re not satisfied with your results, you’re free to return the filter within the first 6 months of use for a full refund. You also get a limited lifetime warranty. And SpringWell’s customer support is said to be helpful and cooperative.

Installation
SpringWells are not any more difficult to install than other whole house water filters. There are just a few additional steps required because the systems don’t come preassembled.
Most importantly, there’s a bypass valve so you don’t have to worry about that, and the included step-by-step instructions are easy to follow, also thanks to a great number of images.
If you want you can purchase the optional installation kit. Otherwise, you’ll probably need to make a trip to the hardware store.
Is outside installation possible? Yes, as long as temperatures are above freezing.
Filter Media Priming
The carbon bed has to soak for 48 hours prior to use. A location suitable for water flow is required.

Maintenance
Like we said, maintenance is kept at a bare minimum, and it’s simple. All there is to do is replacing the sediment pre-filter every 6-9 months. Cost: $40 per year with biannual replacement.
The media bed in the large tank lasts a full 6 years or 1,000,000 gallons. The good news is, you can renew it yourself. There’s no need to call a plumber and since you can continue using the old tank it’s the most cost-effective solution.

CF Series Cons
Our only complaint is that the provided fittings are plastic so there’s a chance of accidental cross-threading. No biggie but we would have preferred metal pieces.
