APEC ESSENCE Series 50 GPD Replacement Filter Set - Complete RO Kit

In this review of the APEC ESSENCE Series 50 GPD replacement filter set, the bottom line is clear: this kit is for owners of under-sink reverse osmosis systems who want a straightforward, long-lasting replacement that restores water taste and protects the membrane. The reviewer found the set to be a complete, easy-to-install set of five stages that addresses sediment, chlorine taste and odor, and includes a high rejection TFC RO membrane, making it the single practical choice for maintaining a 50 GPD ROES-50 type system.

Key Features

• Complete 5-stage set: Includes sediment, two carbon blocks, a high rejection TFC RO membrane and a post carbon filter to give full-system replacement in one package.
• Effective sediment protection: The 1st stage 5 micron sediment filter reduces dust, particles and rust to protect downstream filters and the membrane.
• Chlorine and taste removal: The 2nd and 3rd stage 10 micron extruded carbon block filters remove chlorine, tastes, odors and many common VOCs for cleaner tasting water.
• High rejection membrane: The 4th stage TFC reverse osmosis membrane provides broad contaminant rejection appropriate for a 50 GPD system.
• Final polishing: The 5th stage coconut shell carbon post filter removes any last residuals to improve drinking water flavor.

Who It's For

This filter set is aimed at homeowners and renters who already own an under-sink RO system sized for 50 GPD, specifically users who want a single replacement package that keeps the entire unit performing at peak levels. It is especially useful for people who notice chlorine taste or sediment in supply water and want an affordable annual replacement path.

Those who should look elsewhere include owners of nonstandard or proprietary filter housings and anyone needing a higher capacity membrane than 50 GPD. Also, if a user requires filters with unusual micron ratings or specialized contaminant certifications beyond the described stages, they should verify compatibility before buying.

Pros & Cons

Pros

• Complete set replaces all five stages at once, simplifying maintenance and ensuring proper sequence of filtration.
• Carbon block stages effectively remove chlorine, off tastes and odors, improving water quality and drinking experience.
• Membrane and post carbon longevity make the kit cost effective, with routine filter elements lasting months and membrane years.

Cons

• Kit is designed for standard 10' under-sink housings and 50 GPD systems, so it may not fit proprietary or nonstandard RO systems.

Frequently Asked Questions

How often should these filters be replaced?
Routine sediment and carbon filters last about six months under normal use; the membrane and post carbon can last two to four years depending on water quality.

Will this kit fit my ROES-50 or similar system?
Yes, the kit is compatible with APEC 50 GPD Essence systems and most standard size under counter RO housings; confirm dimensions if you have a proprietary unit.

Does the set remove chlorine taste and odor?
Yes, the two carbon block stages are designed to remove chlorine, tastes and odors and reduce many common VOCs for improved water flavor.
