What it filters
The WGB32BM uses NSF-certified filter components across its 3 stages, though the system itself does not carry a dedicated NSF 53 or 58 certification (the standards that specifically cover PFAS). iSpring states the carbon stage reduces PFAS; confirm the current claim on the manufacturer's page or the NSF database before relying on it for PFAS specifically.
| Contaminant | Removed | Stage |
|---|---|---|
| Sediment & rust | Yes | Step 1 |
| Iron & manganese | Yes | Step 2 |
| Chlorine & taste | Yes | Step 3 |
| PFAS | Per manufacturer, not independently verified | Step 3 - verify NSF listing |
| Bacteria | No | UV upgrade needed |
Who should buy the iSpring WGB32BM
- Large households needing high flow rate
- City water with iron or manganese issues
- Budget-conscious buyers who want whole house coverage
- Well water with bacteria - use Aquasana Rhino EQ-1000 instead
- People who need dedicated NSF 53 certification - use SpringWell CF+
