It's rated 0.35um absolute which should get rid of all yeast (and other microorganisms as well!) The challenge for home winemaking is sterilizing all the remaining parts of your filtering and storage (not to mention bottling) apparatus. At the winery where I work, everything downstream of the final sterile filter is steamed (including a steam hose connecting the filter to the destination tank), and all connections sprayed with 70% ethanol as they are made. We can do a pretty good job on the home winemaking scale by thoroughly sanitizing with, eg peroxycarb, but it won't remove all risk.
I'm also concerned that it's been a month since you filtered... I would ideally want to do my final pass filtration within a few days of bottling.
