Usability
The RO-90 is the volume choice in APEC's Ultimate line, aimed at households that cook with filtered water and refill bottles rather than sip. Its strongest attribute is the membrane and tank pairing: independent lab testing of the closely related Essence chassis returned complete removal of lead, arsenic, uranium and lithium, and the 90 GPD rating refills a drained four-gallon tank in roughly ninety minutes. Its weakest is certification scope. The WQA Gold Seal covers NSF/ANSI 58, and the reduction behind that seal is total dissolved solids rather than the fifty-plus contaminants the product copy lists. What the buyer trades away is verified breadth, because APEC publishes no per-contaminant reduction percentage for any model in the range. The three-to-one drain ratio is the other cost and it cannot be improved without moving to the permeate-pumped RO-PERM.
- 90 GPD rating refills a four-gallon tank in about ninety minutes
- WQA Gold Seal certification to NSF/ANSI 58
- Filmtec membrane rated to 99 percent TDS rejection
- Full five-stage replacement set runs around 80 dollars a year
- Assembled in California with lifetime phone and chat support
- Certified scope is TDS reduction, against copy claiming up to 99 percent of contaminants
- No published reduction percentage for any named contaminant
- Roughly three gallons to drain for every gallon produced
- Warranty is one year unless registered within eight weeks of purchase
- Housings unscrew rather than twist, so filter changes need the wrench and a bucket
The APEC Water Systems RO-90 is a five-stage under-sink reverse osmosis system rated at 90 gallons per day, built around a Filmtec thin-film composite membrane with two carbon block pre-filters and a coconut shell post carbon. It ships with a four-gallon pressurised storage tank and a lead-free designer faucet. APEC holds a WQA Gold Seal on this model certifying it to NSF/ANSI 58. Assembly is at the company facility in City of Industry, California.
