Product review (4 stars): Filter filters filteringly well.
Its a filter, and it filters really good.  If it didn't filter real good it wouldn't be a filter, it would be a glorified bottle with a hole that runs water through.  But its a filtering filter that filters like a filter should, so I am pleased with this filters performance.  If said filter should ever fail to filter as a filter should filter, I will filter my review as such.
