Our verdict
A well-specced modern dispenser from an established filter brand, held back from the top tier only by thinner published certification detail. A reasonable pick if tank size and looks lead your list.
Specifications & certification
| Type | Countertop reverse osmosis |
| How it works | A plug-in countertop dispenser with a generous 4.5-litre (152 oz) feed tank and a 3.5:1 pure-to-drain ratio - fewer trips to the sink than most tank-based rivals. |
| Certification status | Frizzlife's spec line reads 'NSF/ANSI 58 Certified RO Membrane' - that wording certifies the membrane specification; Frizzlife does not publish a whole-system certification sentence for the WB99-C, and we do not upgrade it to one. |
| Filter life | See Frizzlife's cartridge schedule for the WB99-C |
| Replacement filters | WB99-C cartridges via Frizzlife |
| Running cost | Check Frizzlife for current WB99-C cartridge pricing |
| Flow / pace | 100 GPD |
| Size | 9 in L x 16.5 in W x 14.8 in H |
| Power & plumbing | Plug-in. No plumbing. |
| Warranty | Frizzlife's standard 1-year warranty terms apply |
What it claims to reduce
These are Frizzlife's own published figures, graded by the certification status above - we do not run a lab, and we do not upgrade a brand's wording.
- 100 GPD RO purification
- Real-time TDS display (per Frizzlife's product materials)
Strengths
- Largest feed tank in this group
- Better drain ratio (3.5:1) than most batch RO units
- Clean, appliance-like design
Trade-offs
- Certification wording covers the membrane, not a named whole-system listing
- Newer model - shorter track record than AquaTru or RKIN
