Our verdict on the APEC Water Systems RO-90

The APEC RO-90 is an under-sink reverse-osmosis system WQA-listed under NSF/ANSI 58 for reduction of 12 contaminants, including lead, TDS, and Arsenic (V), and under NSF/ANSI 372 as a certified lead-free product, with a WQA-certified 33.3 GPD production rate as of 2026-09-11. It needs a cold-water feed and a drain connection and must stay within APEC's published feed-water limits.[1][2]

Best for

  • Buyers with under-sink space for a point-of-use system, a cold-water connection, and a drain outlet for a DIY reverse-osmosis install.
  • Municipal-water homes, or well-water homes with adequate disinfection, within APEC's published 40-85 psi, 40-100 °F, pH 2-11, and 2,000 ppm TDS limits for the standard (non-pumped) RO-90.

Not for

  • Water outside the published pressure (40-85 psi), temperature (40-100 °F), pH (2-11), or TDS (2,000 ppm) limits for the standard, non-pumped RO-90.
  • Microbiologically unsafe or unknown-quality water without adequate disinfection before or after the system.
  • Sites without a drain connection, an indoor sheltered location away from weather extremes, or feed pressure that cannot be raised above 40 psi without adding a booster pump.

Manufacturer documentation

Ongoing maintenance

  • Replace the stage 1-3 pre-filters at least every 6-12 months; the manual's base schedule is 12 months on city water, and well water with heavy sediment may need earlier replacement.
  • Replace the stage-4 membrane (MEM-90) every 3-5 years on city water or every 2-3 years on private well water, depending on water quality, usage, and prefilter maintenance.
  • Replace the stage-5 carbon post-filter every 3-5 years, ideally at the same time as the membrane.
  • Replace filter-housing O-rings every year. — every 12 months
  • Replace the stage 1-3 filter housings every 5 years. — every 60 months

APEC Water Systems RO-90 questions, answered

Is the APEC RO-90 WQA certified?

Verified health claim

Yes — WQA lists the APEC RO-90 under NSF/ANSI 58 for reduction of Arsenic (V), Barium, Cadmium, Copper, Fluoride, Hexavalent Chromium, Lead, Radium 226/228, Selenium, TDS, Trivalent Chromium, and Turbidity, and separately under NSF/ANSI 372 as a certified lead-free product, both as of 2026-09-11. APEC's own marketing page also claims reduction of Arsenic+3 (trivalent arsenic) and general 'Radioactivity,' which are broader than what the WQA listing itself certifies — the listing's arsenic claim covers only Arsenic (V), and its radioactivity-related claim is specifically Radium 226/228.

Sources: [1][2][3]

How much does the APEC RO-90 cost?

The RO-90 was $229.95 on Amazon and $264.99 direct from APEC on 2026-09-11. Prices change, so the date matters.

Sources: [1][2]

How often should I replace APEC RO-90 filters?

Replace the three pre-filters at least every 6-12 months, the stage-4 membrane (MEM-90) every 3-5 years on city water or 2-3 years on well water, and the stage-5 carbon post-filter every 3-5 years alongside the membrane. APEC also recommends yearly O-ring replacement and replacing the three pre-filter housings every 5 years.

Sources: [1]

Can the APEC RO-90 be used with well water?

Verified health claim

Yes — APEC's manual gives separate private-well maintenance guidance for the RO-90, but water that is microbiologically unsafe or of unknown quality needs adequate disinfection before or after the system. Well-water pre-filters may also need replacement sooner than the 12-month city-water interval under heavy sediment.

Sources: [1]

How much water does the APEC RO-90 produce?

WQA's exact-model listing reports a 33.3 GPD certified daily production rate, well below APEC's own marketed rating of 90 GPD at 60 psi (about 75 GPD at 50 psi and 77 °F). Actual output depends on feed pressure and temperature.

Sources: [1][2]

Does the APEC RO-90 need a drain connection?

Yes — the RO-90 is a standard point-of-use RO system that drains concentrate water through a drain saddle fitted to a 1/4-inch hole in the household drain pipe; it is not designed to run without a drain connection.

What we could not establish, and why

FieldWhy it is blank
fit.bathroomsServedAPEC's product page and the version 7.2 manual do not publish a bathrooms-served range for this point-of-use system.
fit.householdSizeAPEC publishes tank capacity and daily production figures but no rated household-size range.
fit.serviceFlowGpmThe brand page and manual publish daily membrane output (GPD) and pressure-dependent tank fill volumes, not a continuous faucet service-flow value in gpm.
fit.connectionSizeThe manual and brand page describe a supplied 1/2-inch to 3/8-inch feed-water adapter rather than a single fixed connection size, which the schema's single-quantity field cannot represent honestly.
fit.requiresElectricityThe manual describes a non-pump, purely plumbed system with no electrical-installation step, but it does not explicitly state an electricity requirement as a yes/no specification.
cost.msrpAPEC's own product page shows only a single 'Sale price' of $264.99 with no distinct 'Regular price' value rendered, and no other source states a manufacturer suggested retail price.
cost.replacementScheduleThe manual gives 6-12 month and 2-5 year ranges for the pre-filters, membrane, and post-filter rather than single intervals, which the schema's per-row single intervalMonths/intervalGallons field cannot represent without inventing a specific number the manual does not state.
cost.tenYearTotalUsdA single ten-year total cannot be honestly computed because the underlying replacement intervals are ranges (see cost.replacementSchedule), not single per-year figures.
cost.wasteRatioNeither the brand page nor the manual publishes a buyer-facing waste-to-product drain ratio for the installed tank system.
install.estimatedHoursAPEC calls installation DIY and publishes detailed steps and tools, but the product page, manual, and official video do not state an estimated completion time.
