How do I order replacement filters for my APEC drinking water filtration system?
Start by clicking on the photo of your APEC model, then add the needed filters to your cart. Remember, the RO membrane typically requires replacement about every two years, and the sediment and carbon filters should be changed every 6 to 12 months depending on your water consumption and water quality.
Will these compatible filters fit my APEC RO filtration system?

What contaminants will these APEC-compatible filters remove?
APEC reverse osmosis systems typically reduce up to 99% of contaminants, including chlorine, lead, arsenic, VOCs, fluoride, and more, thanks to multi-stage filtering and a TFC membrane. This delivers cleaner, better-tasting water at the tap. APEC-compatible reverse osmosis filters and membrane can remove common pollutants from water including pesticides, sulfates, fluoride, nitrates, lead, pharmaceuticals, arsenic and more. The RO system's carbon filter will also remove chloramines and chlorine.

How often should I replace filters in my APEC reverse osmosis system?
For most APEC RO systems like the popular ROES-50, pre-filters (sediment and carbon) should be replaced every 6–12 months and the RO membrane every 2 years, depending on water usage and quality. Regular changes ensure optimal contaminant removal and system performance. For replacements, visit the RO Replacement Filters & Parts collection.
Are APEC RO filters compatible with other brand systems?
Many APEC filters use standard 10″ housings and sizes, but compatibility depends on your specific model. Always match filter size and type to your system’s requirements before ordering. Use the RO System Identification Guide to confirm compatibility.
Can I install APEC RO filters myself?
Yes — most APEC RO systems are designed for DIY filter replacements with simple twist-off housings. Always shut off water and depressurize the system first, then follow step-by-step instructions in the RO Filter Replacement Guide
How do I know when my APEC RO membrane needs replacement?
Signs you need a new membrane include higher TDS readings, slow water flow, reduced water output, or lingering tastes/odors despite fresh pre-filters. Regular testing with a TDS meter helps you track membrane health.
What size APEC RO system do I need for my household?
Choose based on daily water needs and household size. A 50 GPD system (like ROES-50) fits most small to medium kitchens, while larger families may benefit from 75–100 GPD capacity. For options and specs, browse the APEC RO Systems.
