We offer two replacement filter kits so you can get exactly what you need — and avoid paying for filters you don’t.
-
Year 1 Kit (Includes RO Membrane):
Ideal for your first full replacement, this kit includes all filters plus the RO membrane, which typically lasts up to 24 months. -
Year 2 Kit found on this page (Without RO Membrane):
After the first year, you only need to replace the pre- and post-filters, since the RO membrane is still good for another year. This kit helps you save money while keeping your system performing like new.
By offering two kits, we make it easy to follow the recommended replacement schedule and reduce waste — so you only buy what your system truly needs.
*Filters may need to be replaced more often than indicated, depending on water contaminant levels and volume of water being treated.
Replacements & Add Ons
Q:
How do Goldline under-sink reverse osmosis filter systems work?
A:
Goldline under-sink RO systems work by forcing tap water through a series of filters and a semipermeable membrane. Contaminants, including sediments, chlorine, and certain heavy metals, are trapped and removed. The clean, filtered water is then stored in a tank and ready for use, while the impurities are flushed out through a waste line.
Q:
How often do I need to change the filters and membrane in my Goldline reverse osmosis filtration system?
A:
For optimal performance of your Goldline reverse osmosis filtration system, it's crucial to maintain it regularly. Typically, pre-filters, like the sediment and carbon filters, should be replaced every 6-12 months depending on water quality and usage. The RO membrane should usually be replaced approximately every 2 years. Always consult your system's manual to ensure you follow the specific recommendations for your particular model. Regular maintenance not only ensures consistent water quality but also extends the lifespan of your Goldline RO system.<

Q:
What contaminants does my Goldline reverse osmosis filter system remove?
A:
Your Goldline reverse 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.

Q:
What filters are included in the GoldLine Model 50 5-Stage RO replacement set?
A:
The GoldLine Model 50 uses a 5-stage configuration: a sediment pre-filter, two carbon block pre-filters, a 50 GPD RO membrane, and a GAC post-carbon filter for taste and odor. Each stage targets specific contaminants before final polishing. You can find filter options in the GoldLine Model 50 Replacement Filters collection.
Q:
How often should I replace the filters in my GoldLine Model 50 RO system?
A:
Replace the sediment and carbon pre-filters every 6–12 months, the RO membrane about every 24 months, and the post-carbon filter every 6–12 months to maintain peak performance and water quality.
Q:
Can I buy a complete filter kit for the GoldLine Model 50 RO system?
A:
Yes. ESP offers a complete GoldLine Model 50 Filter Replacement Kit with RO membrane so you can replace all core elements at once. Find it in the GoldLine Model 50 Replacement Filters collection.
Q:
Why is the RO membrane important in the GoldLine Model 50 system?
A:
The TFC RO membrane is the heart of the system — it removes dissolved solids and microscopic contaminants that pre-filters can’t catch. Replacing it on schedule (typically ~2 years) helps ensure clean, safe drinking water.
Q:
How do I know when to change GoldLine Model 50 filters?
A:
Common signs include slower water output, discoloration, or changes in taste/odor. If water flow decreases or TDS levels rise, replace the appropriate filters even if it’s before the suggested schedule.
Q:
Are GoldLine Model 50 replacement filters easy to install?
A:
Yes — these filters are designed for simple DIY replacement. Turn off the feed water, relieve pressure, then pull out the old cartridges and insert new ones following the system manual. For help in replacing your filters, use the RO Filter Install Guide.
