Suits our GT1-39, or any kits of same size that have a pre-carbon, followed by a membrane, then a post carbon filter.
Membrane need replacing from 1 year on, pending the water quality and satisfaction with water flow.
If a membrane replacement is not required and you just wish to replace your carbon filters, then you should check our GT4-6 Carbon Filters. These filters are ideal for Reverse Osmosis, and are the same kind we use as our front line filter.
How do I know if the Membrane needs replacing?
This can be difficult for the home owner to decide, but generally the taste/hardness of the water determines this, to the point where you may be suspicious to if the membrane is fully functioning. Another indication is the water flow through the membrane. If your flow rate decreases rapidly this can be another indication of membrane blockage.
If you are in doubt, send us a sample of your pre and post membrane water and we will check it free of charge and advise you of if your membrane is still functioning correctly.
