The RO-Hi solves a specific irritation with tank reverse osmosis, which is how long a quarter-inch line takes to fill a pitcher. Its strongest attribute is the three-eighths inch output path and matched faucet, which roughly doubles dispensing speed without changing the production rate. Its weakest is that nothing else changes: the membrane is the same 90 GPD unit as the RO-90, so the tank refills at exactly the same rate and the drain ratio is unaffected. Certification is the same WQA Gold Seal to NSF/ANSI 58 covering TDS reduction. At 103 dollars over the RO-90 the buyer is paying for the time between opening the tap and filling a glass, which matters in a busy kitchen and not at all in a quiet one.
- Three-eighths inch output tubing roughly doubles faucet flow over standard quarter-inch
- WQA Gold Seal certification to NSF/ANSI 58
- Same Filmtec membrane and four-gallon tank as the RO-90
- Matched lead-free faucet included rather than sold as an upgrade
- Assembled in California with lifetime technical support
- Faster dispensing does not change the 90 GPD production rate or refill time
- 103 dollars over the RO-90 for tubing and a faucet
- Certified scope is TDS reduction only
- Warranty is one year unless registered within eight weeks
- Drain ratio is unchanged from the standard Ultimate models
The APEC Water Systems RO-Hi is a five-stage 90 gallon per day under-sink reverse osmosis system fitted with three-eighths inch output tubing and a matched faucet to raise dispensing speed.
