RO Full Service Kit, 6 Stage
All six stages. When the membrane is due.
Every cartridge for a six-stage under-sink RO in one box: sediment, GAC, carbon block, a 75 GPD membrane, the inline post-carbon and the 4-in-1 re-mineraliser. Fits the AquaShield and any standard 10 inch system. Twenty minutes with the spanner from the original box and the system is back to day one.

When to buy this kit and when to buy the small one
The three pre-filters change every six months, the post-carbon and re-mineraliser every year, the membrane every two to three years. Most years, the pre-filter kit twice plus the two inline stages once is the right shopping list. The year the membrane is due, or the year you inherit a system with no service history, buy this kit and start the clock again.
The membrane in the box
The kit carries a 75 GPD membrane: 284 litres a day at 4 bar, the size most under-sink systems in South Africa were sold with, and several times what a household drinks. In an AquaShield, which ships with a 100 GPD membrane, it fits the same 1812 housing and refills the 12 litre tank in about an hour instead of forty minutes. The 75 GPD is the replacement membrane we stock; the 100 GPD is the one the complete AquaShield ships with, and at the tap the difference does not show.
Fitting, twenty minutes
The three housings as for the pre-filter kit. The membrane: unscrew the long horizontal housing, pull the old element with pliers, push the new one in O-ring end first. The two inline stages: push the tubes out, screw the new elbows in with the arrows pointing to the tap, push the tubes back. Run the first two tanks to the drain to flush the membrane preservative.

How often should you change water filter cartridges in South Africa?
Six months is the number for most cartridges on municipal water, and shorter on a borehole. The full table by stage and water source, and the signs that bring a change forward.
Which replacement cartridges fit my RO system? The 10 inch standard explained
Measure the cartridge, not the brand. Nearly every under-sink RO sold in South Africa takes the same 10 inch cartridges and the same membrane. How to check in a minute.
How to change the filters on a reverse osmosis system, in fifteen minutes
Three cartridges, one spanner, a bowl and fifteen minutes. The order they go in, the two things people get wrong, and the calendar that keeps the membrane alive.
