Features katadyn befree filter 1l

Flexible 1-liter drum with Katadyn brand water treatment filter designed to have clean water available for consumption anywhere and at any time.

The BeFree filter bottle is particularly useful, simple and quick to use. It is only necessary to fill the tank and it can be used immediately, since it filters any particles or bacteria in suspension thanks to the EZ-Clean membrane, its filter with 0.1 micron hollow fibers ( 0.0001mm).

Weighing 63 grams and with a very small empty volume, this soft flask is perfect for activities where we know that we can find water courses that do not come from clean sources. Essential in hiking, trail running and canyoning, it is also a perfect complement in other mountain activities and on trips due to its simplicity and ease of transport. This system does not modify the taste of the water and does not require a waiting time to act.

The BeFree filter has a filtering capacity of up to 1000 liters which is somewhat reduced when it is used permanently in particularly dirty water. Its output flow is 2 liters per minute.

Maintenance is very simple and fast, you just have to wash the filter with clean water and shake to expel any remaining particles and it is ready for new uses.

Hydrapak® Made of TPU thermoplastic polyurethane, 100% free of PVC and BPA. Size compatible with any flexible tank compartment of trail running backpacks. Dimensions: 8 x 6.5 x 26.5 cm.

Features:
  • Effective filter against microorganisms and particles.
  • Valid for use in cloudy water.
  • Practical for very frequent use on all types of trips
  • Hollow fiber filter 0.1 microns.
  • Weight approximately 63 g.
