Try measuring your TDS at various points during the filtration process (e.g. from tap, after pre-filters, after RO etc) to get a real idea of performance. With our low TDS water in GVRD, your TDS measurements post-DI will measure 1 for decades, but that doesn't mean your filters are OK.

I would definitely change the pre-filters after that bout of super turbid water we had in November. My prefilters were nasty after that episode.
