    i change mine once a month because when i changed it every six months, my RO membrane wasn't lasting. they are pretty cheap so there is not much added expense when compared to having to change out the RO and DI every 4 months.

    If changing your sediment filter every 6 weeks causes your membrane to work harder, you are using filters which are too coarse and are providing little protection.

    The sole purpose of the sediment filter is to protect the carbon block. The purpose of the carbon block is to protect the RO membrane. The purpose of the membrane is to protect the DI resin.

    Switch to better sediment filters and carbon blocks and I'll bet they all last longer including the membrane. Here is a good article on filter selection:
