In this comparison, we look at three bestsellers: the versatile Sawyer Mini, the rugged LifeStraw Peak straw, and the high-capacity Membrane Solutions 6L gravity system. Which one will be best for you?

1. Sawyer Mini - The King of Versatility
The Sawyer Mini is a legend you'll find in the pack of every second long-distance hiker. Its greatest advantage is its compatibility. Thanks to a standard 28mm thread, you can screw it onto most regular PET bottles available in any store.
- Multiple methods of use: As a straw, screwed onto a bottle, integrated into a hydration system, or as a gravity filter.
- Extreme lifespan: With proper backwashing, the filter is virtually indestructible.
- Weight: The lightest option in the comparison, perfect for minimalists.

2. LifeStraw Peak Series - Simplicity and Reliability
The new Peak series is an evolution of the classic "straw." It is more robust than the Sawyer and designed not to clog as easily when dealing with murky water. Ideal for those who want a filter always at hand without unnecessary accessories.
- Armored housing: Made of premium materials, resistant to rough handling in the field.
- Fast flow: Allows for instant thirst quenching directly from the source.
- Ready for action: Requires no extra bags – you simply put it in the water and drink.

3. Membrane Solutions Gravity 6L – Camp Comfort
This is a solution for those who value convenience. Instead of struggling to squeeze water through a small filter, you hang the bag on a tree and let gravity do the work for you.
- Effortless filtering: Perfect when you need a large amount of water for cooking or for several people.
- Large capacity: 6 liters is enough for the evening and morning needs of an entire camp.
- Gravity system: Water flows on its own while you take care of setting up the tent.
