i have this pur explorer water filter, i used it on a few hikes back in the day and stored it properly.
its in great shape but do you think it is ok to use after all these years?
thanks

Yeah, it's ok--the filter will last forever.

I would try it at home. Sometimes the hoses or plastic degrades and gets brittle.

I'm not sure, but some may have some iodine filter, and that's no longer good, if it's present. But it's not required to have.

I've heard of filtering water with dye as a means of testing the integrity of the cartridge. I would go to your local REI or something equivalent to pick their brains. Here's a thread that talks about using dye: http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=35560

This will not work with a filter.

It is a procedure used with First Need purifiers. No filter on the planet will filter out dye - that isn't what they are designed to do.

AGAIN - The First Need is not a filter, as represented in the backpackinglight thread - it is a purifier and in addition to the large bacteria, cysts and protozoa, it will remove viruses - which are incredibly small and no FILTER will remove.
