Water Filter FAQs
Water Filter Maintenance & Care
Filter Changes: Is it necessary to change the filters every six months?
It is recommended to change the 1st, 2nd, and 3rd stage filters every six months. By changing the pre-filters (1st, 2nd, 3rd) on a regular six month basis you will avoid dirt and chemicals that will plug the RO membrane. Your local water conditions can affect how often you need to change your filters.
Flow Restrictor: Is it necessary to change the Flow Restrictor when I change the RO Membrane?
No, you don’t have to change your flow restrictor with our RO System. Express Water uses a newer “inline flow restrictor”. Unlike other varieties this flow restrictor can be cleaned, so there is no need to replace it when you replace your RO Membrane.
