Hi all -

I'm looking for a way to remove particulates from water.  These particulates
are not removed by a 0.2 um filter.  We use a few liters of water per day,
and would prefer a higher-capacity filter (i.e. change filters every month,
as opposed to every use).  I imagine the semiconductor industry
already has something like this.  Could someone point me at a fix?
