SpringWell CF+ Review 2026
This review covers the SpringWell CF+ whole-house filter. We looked for its certifications in the NSF, IAPMO R&T and WQA listings and mapped the specs. Here's our honest verdict on whether the CF+ is worth it.
Whole house, catalytic carbon. The maker lists NSF 42 and 53 for the components; we could not find either in the NSF, IAPMO R&T or WQA listings, and there is no purchase link for this one yet.
Not confirmed does not mean false: it means we could not find that certification in the NSF, IAPMO or WQA listings, so judge this one on the specs above, which we could check.
Get it if Chloramine, not just chlorine, is what your utility uses, and you want whole-house treatment.

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. We searched the NSF, IAPMO R&T and WQA directories on 3 October 2026 and found no listing for SpringWell, so the reductions below are SpringWell's own claims.
| Contaminant | SpringWell's claim | Standard SpringWell cites |
|---|---|---|
| PFAS (PFOA, PFOS) | Claimed | NSF 53, not found |
| Lead | Claimed | NSF 53, not found |
| Chlorine & chloramines | Claimed | NSF 42, not found |
| VOCs | Claimed | NSF 53, not found |
| 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
