Separate the 2 plastic housing halves of the VisiFilter in the following manner.
a)
Grasp the VisiFilter in the palm of the hand with the Male Nib (air hose connection) marked "FLOW
IN" facing you.

Pull against one of the Wing Tabs while pulling on the Male Nib with the free hand to open the
interconnection of the plastic housings at that Wing Tab.

Pull against the second Wing Tab while pulling on the Male Nib to open the remaining
