Description
The four replacement filters for a standard 5-stage reverse osmosis system — everything you change at a routine service.
The RO membrane is not included in the standard pack. If your membrane is due as well, choose "Add 100 GPD membrane" above and it goes in the same box.
What's in the pack
- 5 micron sediment filter — catches rust, sand and grit before it reaches the rest of the system.
- Granular carbon (GAC) filter — takes out chlorine, taste and smell. Chlorine damages the membrane, so this one matters.
- 1 micron sediment filter — a finer second pass to protect the membrane.
- Post-carbon (inline) filter — final polish on the water on its way to the tap.
Optional: 100 GPD RO membrane
The membrane is the stage that removes the dissolved stuff — fluoride, nitrates, lead, limescale minerals. It lasts a lot longer than the filters, typically 2–3 years, so most filter changes don't need one. If the tank has got slow to fill or the taste has dropped off, it's probably due. Pick the "Add 100 GPD membrane" option and you get the four filters plus a new membrane.
How often?
Change the four filters every 6 months. Change the membrane every 2–3 years, sooner on hard or borehole water.
Will it fit my system?
These are standard 10-inch cartridges, and the optional membrane is the standard 1812 size. They fit any 5-stage RO with standard housings — EcoSoft, Clack, Puricom, Pure Pro and most others sold in Ireland. If you have a 6-stage system with a mineraliser, use the 6-stage pack instead. Not sure? Send us a photo of your unit and we'll tell you.
Fitting them
Turn off the feed valve, release the pressure at the tap, unscrew the housings and swap the cartridges. If you're changing the membrane too, it slides out of its own housing at the top — pull the old one, push the new one in the same way round. Most people do it themselves in 15 minutes with the housing spanner that came with the system. If you'd rather we did it, we offer a fitting service across Dublin and Leinster — get in touch.
