Good strainer for coffee stout

I made a coffee stout and instead of making a coffee toddy I just added the coarse grounds directly to the primary. When I rack to keg I use a CO2 push with a ported carboy cap. I’m looking for something to filter out the grounds without introducting O2 into the beer. Would this work, or does somebody have any other suggestions?

I made one recently and the grounds did end up in the siphon. Which side would you put the bag? Personally, I would use a smaller bag if possible.

Next time I make this, I’ll probably use a bag like that to hold the grounds.

I’d like to put something on the end of tubing that goes into the beer to stop the grounds from even coming into the tubing.
