Our verdict
The budget pick with receipts: an actual SGS report behind the numbers, at the lowest price in the class. Accept the test-report (not certification) status and the thirstier drain ratio, and it is a lot of RO for the money.
Specifications & certification
| Type | Countertop reverse osmosis |
| How it works | Five stages in just two twist-and-lock cartridges (CF and RO). A 1.3-gallon feed tank, one-touch dispensing at 6/12/15 oz, and a recycling filtration loop that re-passes water to stretch each tank. |
| Certification status | SimPure's wording: 'Independently verified by SGS to NSF/ANSI 58 standards.' That is an SGS test report (2022) - real third-party data, but a test report is not an NSF certification listing, and SimPure's page never claims it is. |
| Filter life | Both cartridges about 6 months per the product page |
| Replacement filters | CF $22.99 - RO $34.99 - kits $53.99 (6 mo) / $99.99 (12 mo) |
| Running cost | $99.99/yr (12-month kit) |
| Flow / pace | 100 GPD; pure-to-drain 4:1 |
| Size | 18 in L x 8 in W x 16.1 in H, 14.8 lb |
| Power & plumbing | Plug-in (110V). No plumbing. |
| Warranty | '1+1 year' warranty per SimPure; 30-day returns |
What it claims to reduce
These are SimPure'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.
- Chlorine over 99.45% (SGS-tested)
- PFAS (PFOA/PFOS) over 98.75% (SGS test report; PFOS separately over 98.30%)
- Lead over 98.46%
- Fluoride over 97.28%
- TDS over 98.64%
Strengths
- Cheapest countertop RO we track with real third-party test data
- Two cartridges only - maintenance takes a minute
- Published SGS numbers for PFAS, lead and fluoride
Trade-offs
- Tested to NSF/ANSI 58 - not certified
- 4:1 drain ratio wastes more water than rivals
- Filter-life figures conflict between SimPure's own pages (6 vs 6-12 months)
