Hydration & Water Filters

Q: What’s the best water filter for camping?

For solo use, squeeze filters like Sawyer MINI are ideal. For groups, gravity or pump purifiers like MSR or Katadyn handle larger volumes efficiently.

Q: How often should I clean my hydration bladder?

Clean after each use with mild soap and a brush kit, and store open to prevent mildew.

Q: Can I use regular water bottles with filters?

Yes. Filter bottles like Grayl and LifeStraw allow you to drink directly from streams or lakes safely.

Clean and dry your hydration bladder after every trip using mild soap and a brush kit. Store with the cap open to prevent mold or mildew buildup.
