Sometimes an on-demand pump will cycle on and off very quickly and repeatedly when it starts up. (Not enough pressure, too much pressure, not enough pressure.....) Don't know an expert to refer you to though.
Why are you changing the filters every month? What size cartridges are they 10" or 20", narrow or wide? You can probably go for at least 3 months and more likely 6 months before you have to change them depending on your usage and how dirty your catchment water is.
