The aerator is there to help prevent splashing when the water hits something in the sink. You can demonstrate it by removing the aerator, turning the faucet on to a position where the water splashes out of the sink then reinstall the aerator and turn the faucet on to the same position to observe the behavior of the water stream. ^_^


An aerator does not cause "chatter".
