To filter or not to filter, aye that is the question.

As you can see from other's responses it is definitely optional. It
is important to bottle clear wine which will not set firther sediment.
This is not usually possible in the 4 to 6 weeks in a kit's
instructions. It will require additional time & rackings. Some
people double up on the clearing agents to help the wine to clear.

Simply put, it's your choice.

Personally, I filter, even though I usually give my kits extra time
and a couple of extra rackings. WHY? Because I think it makes the
wine look better...shine...sparkle.

I believe you asked (sorry deleted the original message) about
filtering equipment. For most home winemakers I would recommend Buon
Vino's Mini Jet. Depending on where you live, your LHBS may rent you
one.

Good Luck, Steve
