You should always refrigerate any bottles you fill for later feedings to prevent bacteria from growing, as well as any open containers of ready-to-feed or concentrate formula. Throw away any mixed formula after 24 hours and any open ready-to-feed or concentrate formula after 48 hours.
Unopened it' can be good for up to two years. However, opened is another matter. Although bottled water is tested that does not mean it is contaminant free. Bacteria can still be present. After opening if you keep it refrigerated it should be ok for up to two weeks.
