EZ-Clean Membrane Cartridge

EZ-Clean Membrane Cartridge — when your BeFree flow slows and cleaning no longer helps, it’s time for a replacement. Compatible with BeFree 0.6 L, 1.0 L, and Gravity 3.0 L. No tools needed — screw off, screw on, done.
Pro tip: Before replacing, make sure the filter is not clogged — fill the flask with fresh water, shake, and squeeze until flow improves. If it doesn’t, swap the cartridge.
On extended trips, always carry a spare.
