We use two filters in line
- Pentek DGD-2501 dual-gradient (25/1 micron)
- Pentek FloPlus-10 carbon block (.5 micron)
Filter housings from Pentek, GE, etc.
Happens we order all that stuff from Filtersfast.com, but mostly because we get all our household filters from them, too -- sediment, drinking water, vacuums, etc. -- so it's just easier... and their prices seem OK anyway.
I have quick-snap fittings on primary hose and first filter housing, interconnector, second filter housing and secondary hose... so everything snaps together in about 30 seconds.
Just saw an ad for a new drinking water filter from Forespar, but they didn't bother to answer my e-mail questions... so I don't know yet whether I'll fool with that or not.
