What replacement filters fit a APEC RO-90?
The APEC RO-90 reverse osmosis system uses 4 filter stages.
Key takeaways
- Reverse Osmosis system by APEC.
- 4 filter stages: Stage 1: High-grade 10 inch high-capacity polypropylene sediment filter - removes dust, particles, and rust; 100% pure polypropylene depth filter with exceptional dirt-holding capacity translates to longer life and fewer change-outs, Stage 2-3: premium extruded carbon block gets rid of unpleasant chlorine, tastes, odors, cloudiness and colors; also removes VOCs and other common chemicals from the water with enhanced absorptive capacity and efficiency, Stage 4: Filmtec (Dow chemical) high rejection TFC reverse osmosis membrane removes up to 99% of total dissolved solids (TDS) and contaminants such as arsenic, lead, fluoride, chromium, radium, bacteria, viruses and much more, Stage 5: advanced 10 inch coconut shell refining carbon - TCR (total contamination removal) filter removes any possible residual taste from the tank.
- Not listed in NSF's database - this brand certifies through WQA or its own testing.
- A cheaper compatible filter set can fit the same housings - confirm its own certification before buying.

NSF certification
The RO-90 isn't listed in NSF's database - this brand certifies through WQA or its own testing, not through an NSF DWTU listing we can independently cite. That isn't proof it doesn't filter well, only that we can't verify a specific contaminant-reduction claim for it here.

Is the APEC RO-90 NSF certified?
The APEC RO-90 isn't listed in the NSF Drinking Water Treatment Units database as of our last check. That doesn't necessarily mean it doesn't filter well - this brand may certify through WQA or its own in-house testing instead. We only claim an NSF reduction when it's independently NSF-listed.
Does the APEC RO-90 remove lead?
We don't have an independent NSF listing for the APEC RO-90, so we can't confirm a lead-reduction claim either way. Check the manufacturer's own certification documents.
Should I buy the genuine filter set or an aftermarket one?
The genuine APEC cartridges are the safe, exact-fit choice. A cheaper compatible set can fit the same housings too - just confirm it carries its own independent certification for the contaminants you care about before buying.
