APEC 90 GPD Complete Replacement Filter Set - Long Life Performance

In this review the APEC 90 GPD Complete Replacement Filter Set is evaluated for homeowners and anyone using an APEC RO-PH90 or similar reverse osmosis system with a pH enhancer kit. The bottom line: this USA-made 6-stage filter set is best for users who want fewer filter changes and consistent impurity removal because the high-capacity pre-filters and a lab-tested Filmtec membrane are designed to last longer and maintain high rejection rates for better drinking water quality.

Key Features

• Complete 6-stage protection: Includes sediment, two carbon block pre-filters, a Dow Filmtec 90 GPD membrane, an inline carbon post filter and a pH+ calcium carbonate re-mineralization filter so systems get full-stage treatment for taste and safety.
• High-capacity pre-filters: The 10 in polypropylene sediment and carbon block cartridges are designed to last over 12 months, reducing maintenance frequency for busy households.
• Filmtec membrane performance: The Dow Filmtec 90 GPD membrane is individually lab tested to guarantee a high rejection rate for a wide range of contaminants.
• Re-mineralization stage: The pH+ calcium carbonate filter adds food-grade calcium minerals back into RO water to improve taste and mouthfeel for drinking and brewing tea or coffee.
• Made in USA: Components and assembly are USA made, which contributes to consistent build quality and supply reliability for replacement parts.

Who It's For

This filter set is ideal for homeowners with an APEC RO-PH90 or any compatible RO system upgraded with a pH enhancer who want fewer filter replacements and dependable contaminant rejection. It suits families and small offices that value better tasting water and convenience from longer-lived pre-filters and a high-capacity membrane.

It is less appropriate for users who need ultra-rare specialty filters not listed here or those who prefer ultra-low initial cost replacement packs; some reviewers note occasional damaged shipments, so buyers who require single-part replacements rather than full sets should consider ordering individual cartridges.

Pros & Cons

Pros

• High-capacity components mean longer intervals between changes and lower ongoing workload.
• Lab-tested Filmtec membrane provides reliable contaminant rejection for safer drinking water.
• pH+ calcium carbonate re-mineralization improves taste and adds beneficial calcium minerals.
• Made in USA construction that supports consistent quality control.

Cons

• Some customers reported mixed impressions of initial taste and occasional damaged filters in transit, so inspect on arrival.
• The full set is focused on standard replacement intervals; users needing only a single part may find the set more than required.
