The filters were designed with the flow in mind so this means one ‘points’ down and the other points up. Another way to say it is the blue cap is on the top of the gold filter and on the bottom of the blue filter (don’t forget- the blue one goes on the right side). Simply remove the 6 thumb screws (don’t forget righty-righty, lefty loosey!) from the base of your Double Chuck, lift off the cover, and remove the filters. NOTE: water will begin to flow out of the filters as soon as you lift one out so be sure to do this on an acceptable work surface.
