APEC Water FILTER-MAX90-38 Complete 90 GPD Replacement Set - Reliable

Our review of the APEC Water FILTER-MAX90-38 finds it best suited for homeowners and DIYers who need a straightforward, high-capacity replacement set for Ultimate series and most standard 10 in reverse osmosis systems. The bottom line: this US made set supplies a 90 GPD Filmtec membrane plus full pre- and post-filtration so the RO unit can maintain high contaminant rejection without frequent part hunting. Installation is simple for someone familiar with under-sink RO plumbing and the included 3/8 in quick connect inline carbon filter makes hookup to upgraded outlets convenient.

Key Features

• Complete replacement set: Contains a sediment, two carbon block filters, one Filmtec RO membrane and a 3/8 in quick connect inline carbon filter so users replace all key filter stages at once.
• High capacity membrane: The Filmtec 90 GPD membrane is lab tested for a high rejection rate, helping reduce a wide variety of dissolved contaminants for cleaner drinking water.
• US made filters: All filters are manufactured in the United States, which reassures buyers about build consistency and material sourcing.
• Standard sizing: The 10 in filter housings fit most industry standard RO systems, making this set a flexible replacement for different brands and models that use 10 in cartridges.
• Pre-filter protection: The polypropylene sediment and carbon block stages remove particles, chlorine, tastes and odors, protecting the RO membrane and extending system life.
• Quick dispense hookup: The 3/8 in quick connect inline carbon filter simplifies connection to upgraded 3/8 in output fittings for faster dispensing setup.

Who It's For

This kit is ideal for owners of APEC Ultimate series RO-Hi, RO-90, RO-PERM and other reverse osmosis systems that accept 10 in filters and a 3/8 in output upgrade. It suits people who prefer replacing all service stages together and expect a membrane rated for higher daily production.

Those who need ultra-fine specialty filters beyond standard RO membranes, or who operate nonstandard sized systems, should check compatibility before buying. Also, if a buyer has recurring leakage issues with their plumbing, addressing fittings and tubing first is recommended since filter replacement alone may not resolve system leaks.

Pros & Cons

Pros

• Comes as a full set including Filmtec 90 GPD membrane, reducing time spent sourcing individual parts.
• Good pre-filter protection with a polypropylene sediment stage and two carbon blocks to protect the membrane.

Cons

• Some customers report mixed water quality results depending on system condition, so performance depends on correct installation and the existing plumbing.
