My Sawyer filters don't come apart--the shells are sealed and the media can't be removed.

I just shake out as much water as I can from the intake and discharge ends then leave them in a sunny apot. I'm not convinced they ever completely dry out, so the bleach treatment before storage seems prudent. FWIW the Squeeze cartridge has a larger opening on the intake side so may have a better chance of drying out than the in-line cartridge with its tiny hose connectors.

Cheers,
