Never store a wet Sawyer filter in a plastic bag. That’s mold’s vacation home. Instead, let it air dry completely. Then pop it in a breatheable pouch. Your filter likes fresh air. It’s high-maintenance like that.
Also, don’t freeze your filter. Ice crystals can tear the fibers. Then your filter becomes a fancy straw that does exactly nothing. If you live somewhere cold, keep it inside your sleeping bag at night. Yes, cuddle your water filter. Don’t judge me.
What about the squeeze bag?
Your filter’s buddy—the dirty water bag—needs love too. Rinse it with soapy water after every trip. Dry it inside out. If it smells like a dead fish, boil it for a minute. Yes, you can boil Sawyer bags. They’re made of tough plastic. Just don’t melt them onto a stove burner. That’s a rookie mistake.

Pro tip: put a drop of bleach in the bag, fill with water, and shake. Wait 30 minutes, then rinse. The bag will smell like a swimming pool. But the next water you filter will taste like nothing. Perfect.
