I use a gravity filter and works pretty well.
Some others on the forum have said they would never filter, and in truth, it is rarely necessary. Time is a excellent clarifier. A properly degassed wine will clear of it's own accord if you leave it alone. The rationale for not filtering is that some claim it strips the taste. I've not noticed personally.
I've just finished the MM Trebbiano, which include an instruction to filter..
The downside of the gravity filter is time. It takes about an hour to filter 6 gallons and, if it is really cloudy requires a filter change part way through. While it is filtering, the filtered wine is sitting exposed to air, which of course we try to avoid.
