The RO-QUICK90 targets the one thing owners of the standard APEC systems complain about after installation, which is that a filter change means a wrench, a bucket and three unscrewed housings. Its strongest attribute is the twist cartridge design, which turns that job into a minute of work. Its weakest is that it drops to four stages while keeping the same 90 GPD rating, so one carbon block is gone from the pre-treatment path. It also carries no certification, which puts it behind the cheaper ROES-50 on the only axis APEC can actually evidence. The buyer is trading a filtration stage and a WQA listing for cabinet space and easier maintenance, which is a reasonable swap for a renter and a poor one for anyone buying on contaminant reduction.
- Twist cartridges make a filter change a one-minute job
- Compact frame fits cabinets that will not take a full Ultimate system
- 90 GPD production rate matches the larger Ultimate models
- Cheapest system in the Ultimate line
- Assembled in California with lifetime technical support
- No certification of any kind, unlike the cheaper ROES-50
- Four stages rather than five, with one carbon block removed from pre-treatment
- Quick-change cartridges are proprietary and cost more than standard housings over time
- Warranty is one year unless registered within eight weeks
- Drain ratio is unchanged from the unpumped Ultimate models
The APEC Water Systems RO-QUICK90 is a four-stage 90 gallon per day under-sink reverse osmosis system built on quick-change twist cartridges rather than the wrench-and-housing arrangement used across the rest of the range. The compact frame is aimed at cabinets that will not take a full Ultimate system. APEC's own product imagery marks this model as uncertified.
