where are you reading the pressure, before the filter, after the filters at the "in" of the mambrane etc.

Pressure gauges cost about £9.99. Its cheap enough to have one on the inlet and another one before the RO.
Until you know where the pressure is being lost all you can do is guess. How long have the prefilters been in?

You need to change the prefilters.
