The ROTL-A1000 is the system APEC built when it decided certification was worth paying for, and it stands apart from the rest of the catalogue because of it. Its strongest attribute is that listing: APEC states IAPMO certification to NSF/ANSI 58 and NSF/ANSI 372, which pairs reverse osmosis performance with lead-free materials rather than covering total dissolved solids alone. Its weakest is that the claim is manufacturer-sourced and IAPMO's directory is a JavaScript search form that could not be queried, so the scope of the 58 listing is unverified here. At 1,000 GPD with a two-to-one drain ratio it is the fastest and second most efficient system APEC sells, and it fills a 16 ounce glass in under six seconds. The buyer trades the ability to dispense during a power cut, and pays 350 dollars over the ROTL-AIO for the certification and the extra output.
- IAPMO certification stated to NSF/ANSI 58 and NSF/ANSI 372, the broadest in the range
- 1,000 GPD on demand with no storage tank
- Two-to-one pure-to-drain ratio
- Front-loading cartridges change quickly without unhooking the system
- Fits an 18 by 10 by 10 inch cabinet space
- Certification claim is manufacturer-stated and IAPMO's directory could not be checked
- APEC publishes no reduction percentage for any contaminant despite the listing
- Requires an under-sink outlet and stops dispensing in a power cut
- 350 dollars more than the ROTL-AIO for the same drain ratio
- Warranty is one year unless registered within eight weeks
The APEC Water Systems ROTL-A1000 is a four-stage tankless under-sink reverse osmosis system rated at 1,000 gallons per day with a two-to-one pure-to-drain ratio. APEC states it is certified by IAPMO to NSF/ANSI 58 and NSF/ANSI 372, which makes it the only system in the range with a listing beyond the WQA Gold Seal. The unit fits a cabinet space of 18 by 10 by 10 inches and requires an electrical outlet. An alkaline five-stage version is sold as the ROTL-A1000ALK.
