LifeStraw Peak Series Straw vs LifeStraw Personal Water Filter Straw

Both are LifeStraw membrane straws with the same 0.2-micron filtration and unlimited shelf life, so the choice comes down to form factor. The Peak Series Straw adds a removable threaded bottom cap that screws onto most bottles and gravity hoses, which makes it more versatile for camp and emergency kits. The Personal Water Filter Straw is the lighter, simpler classic at 1.6 oz with a lanyard, and it carries a long track record of owner satisfaction. Buy the Peak for bottle and gravity-hose flexibility; buy the Personal for the lightest, most proven basic straw.

• Choose the Peak Series Straw if you want to screw it onto a water bottle or gravity hose and want the newer microfilter design that resists silt clogging.
• Choose the Personal Water Filter Straw if you want the lightest, simplest straw with a long, well-documented record and a lanyard for carrying.
