Our verdict
The most likeable countertop RO to live with day-to-day, from the brand that is unusually upfront about not being NSF-certified. Buy it for the design, hot water and warranty - with eyes open that its proof is a lab report, not a certification.
Specifications & certification
| Type | Countertop reverse osmosis with UV-C |
| How it works | Four stages - pre-filter/carbon, RO membrane, VOC carbon - plus always-on UV-C light, a glass pitcher that auto-fills, a live TDS readout, and instant hot water up to 201F. |
| Certification status | Sans states plainly in its own FAQ and data sheet: 'It is not NSF-certified.' Its reductions were measured by SGS (an ISO/IEC 17025-accredited lab) in 2023-24 testing. We respect the honesty - and grade it as tested, not certified. |
| Filter life | Pre/Carbon 12 months - VOC Carbon 12 months - RO membrane 24 months |
| Replacement filters | Pre/Carbon $34.99 - VOC Carbon $34.99 - RO $54.99 |
| Running cost | About $97/yr at list prices |
| Flow / pace | About 0.5 gpm per the performance data sheet |
| Size | Countertop pitcher system; Sans does not publish full dimensions on its product page |
| Power & plumbing | Plug-in (UV-C, heating and TDS monitor) |
| Warranty | 3 years - the longest here - but you must register within 30 days of ordering |
What it claims to reduce
These are Sans'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.
- Lead reduced over 99.3% (SGS data sheet)
- PFOA over 98.8%, PFOS over 99% (SGS data sheet)
- Fluoride over 99.9% (SGS data sheet)
- TDS over 98.6% (SGS data sheet)
Strengths
- 3-year warranty, double most rivals
- Glass pitcher and auto-fill are genuinely pleasant to live with
- Publisher of a full, honest test data sheet
Trade-offs
- Not NSF-certified - SGS lab results only
- Warranty requires registration within 30 days
- Some headline claims elsewhere on Sans's site run ahead of its own data sheet (mercury and selenium measured lower)
