[pct-l] Water Filter

[Kea]

I am looking for a light-weight water filter.  I was going to get a ULA
Amigo Pro filter but that is now out of production.  Next option appears to
be an Aqua Mira Frontier Pro.  But the only mention I have found of flow
rate is 2 litres in 45 minutes.  That strikes me as being a problem.  It
also needs prefilter discs; which are not sold separately.

Anyone have any suggestions?
