Product review (5 stars): A very simple procedure that saves a lot of money!
Lot of people with a lot of drama.  I received the package with 3 refill packs, 1 styrofoam plug, and 1 plastic cup. If your package did not contain these items then you might have not received the original kit.

This is so easy to do:

1) remove filter from unit
2) unscrew big canister cap from filter
3) unscrew top from filter
4) empty out filter over trashcan
5) rinse out filter body in a big bowl --> throw water and any remaining granules down the toilet, nothing will clog here
6) install styrofoam plug
7) fill plastic cup with one packet of granules
8) with cup standing on counter place filter body on top of cup with open side facing in to the cup
9) turn everything 180 degrees to transfer granules in to filter body
10) ensure even distribution, clean off top and threaded area, place cap on filter body
11) soak for 24 hrs --> DONE!
