I have never used a filter in the process of bottling homebrew. I do have an inline filter that I use when kegging to help ensure hop material does not clog up the transfer. I would see some potential for using such a filter when bottling. When kegging, I am able to fully purge the line using CO2 from my tank. If used when bottling, you would have to make sure you fully fill the filter with beer to push out any air.
There are Bouncer branded ones on Amazon. I got a lesser priced one from VacMotion who also used to sell on Amazon. (I am pretty sure Bouncer and VacMotion filters are made by the exact same company.) The VacMotion site lists the filters with a ton if different options as far a connectors, materials, filter size, etc.

I would be curious if anybody has used one of these filters while bottling.
