SpringWell CF+ Review 2026
This SpringWell CF review covers one of the most talked-about whole-house filters in the US. We checked its NSF certifications, mapped the specs, and looked at real owner feedback. Here's our honest verdict on whether the CF+ is worth it.
Editor's pick - Whole house, catalytic carbon, NSF 53 & 42.
- Removes chloramine, not just chlorine
- Whole house - every tap protected
- Lifetime tank warranty
- DIY installation friendly
- Does not remove bacteria
- Limited iron removal
- 9 GPM - not for large homes
Is SpringWell NSF certified?
SpringWell lists the CF+ as using components tested and certified to NSF/ANSI 42 (taste and odor) and NSF/ANSI 53 (health contaminants including PFAS and lead). Note the distinction between "certified components" and a fully system-certified unit, and confirm the specific contaminant you care about on the official NSF International database before buying.
| Contaminant | Removed | NSF Standard |
|---|---|---|
| PFAS (PFOA, PFOS) | Yes | NSF 53 |
| Lead | Yes | NSF 53 |
| Chlorine & chloramines | Yes | NSF 42 |
| VOCs | Yes | NSF 53 |
| Fluoride | No | Use RO instead |
| Bacteria & viruses | No | UV upgrade needed |
Performance & specs
The CF+ uses catalytic carbon block filtration - a higher-grade carbon than standard activated carbon. Catalytic carbon has a larger surface area and is more effective at removing PFAS and chloramines than standard carbon.
SpringWell CF+ vs Aquasana Rhino
On municipal water, the CF+'s closest rival is the Aquasana Rhino EQ-1000. Both are whole-house catalytic-carbon systems with similar contaminant coverage. SpringWell generally wins on long-term value and yearly upkeep and includes a lifetime warranty, while Aquasana has wider retail availability (including Amazon) and stronger brand recognition. Neither removes bacteria on its own - for well water you'd add a UV stage.
Installation
The CF+ installs on the main water line where it enters your home. SpringWell provides detailed video installation guides. Most homeowners with basic plumbing experience can install it in 2-4 hours.
You'll need to shut off the main water supply, cut into the main line, and connect the filter housing. If you're not comfortable with this, a plumber can install it in under an hour.
Who should buy the SpringWell CF+
- Homeowners on city water with PFAS concerns
- Families who want every tap filtered
- People who want low annual maintenance cost
- Well water users with bacteria concerns - add UV upgrade
- Renters - consider under-sink options instead
