I'm in agreement with Doug Hudson's comments.  I will reiterate his point that In Winemaking, Time is Your Best Friend.  Most wines can be cleared with gravity and time alone. 

In the event you need a quicker option, which happens, we have also used a Whole House Water Filter, either while racking or bottling, that can be purchased online and locally.  THIS is the one we use.  Inexpensive filter elements, like THIS 5 micron, can be purchased as need.  Other micron ratings can also be found.  Like the Buon Vino, new filter(s) would be used for each filtering session.  It can filter with gravity racking/bottling, but many winemakers have found Steve Helspers All-In-One Wine Pump to be an excellent investment for multiple winemaking activities, including speeding up this type of filtering.

I’m a newbie member and winemaker, fermenting my second batch of wine using must from Midwest Supplies (also beer brewer since 2017). 

Appreciate advice on filtration. My Sauvignon Blanc is now 4 months in bulk, been transferred twice so still a small amount of residue in the bottom of carboy.

Q: Is there an effective and inexpensive way to filter the wine headed into the bottling bucket before I bottle? Is it necessary to filter? Tell me your journey.
