DO NOT
disassemble and dry out the Purifier Cartridge before storing
it. If the cartridge’s internal fibers dry out, they will no longer pass water; the cartridge must stay
wet inside.
WARNING
DO NOT
use more bleach than recommended, as doing so can damage
the fibers.
WARNING
Disinfect the purifier thoroughly before long-term storage to prevent the
growth of mold, mildew and bacteria. Never use a dishwasher or microwave to disinfect parts because
the high heat will damage or melt them.
