Easy Replacement Process (photos above)
To refill your Filteroo® MAX Fluoride Reduction Cartridge.
1. Begin by unscrewing the cap of a single POSTreat housing, and delicately remove and dispose of the spent media.
2. Access the refill pouches by tearing open the packaging along the pre-notched line. Extract a pair of refill pouches, ensuring one pouch for each POSTreat.
3.Carefully open one pouch by tearing along the dotted line, then gently pour the entire contents into one POSTreat. After securely rescrewing the cap, repeat the process for the second POSTreat. (PLEASE NOTE: You can insert the entire satchel inside the housing rather than open and pour the satchel contents into the housing is you choose.)
4.With the fresh refill in place, proceed to prime your POSTreats. Once primed, these cartridges are now ready for use. Reattach them securely to the primary cartridges within your filter system.
