Water filter Katadyn 8021402 camping, 1 L, blue, max flow 2 L/min

Katadyn 8021402 is a portable camping water filter with a 1 L squeezable reservoir and a maximum flow rate of up to 2 L/min. The unit combines a soft, flexible collection bottle with a hollow-fiber filter element to provide rapid, on-the-go filtration of microbial contaminants from rivers, lakes and uncertain tap sources. The compact blue design is lightweight and intended for outdoor use where quick filtration of small volumes is needed for drinking and food preparation.

Advantages

The hollow-fiber membrane removes bacteria and protozoa without chemical additives while maintaining a high flow rate when the reservoir is squeezed. The soft reservoir is easy to fill, pack and store, and the overall system is lightweight for backpacking and travel. Cleaning is straightforward: simple shaking or backflushing restores flow and reduces downtime during extended trips. The design emphasizes rapid delivery of safe drinking water from natural sources with minimal weight and volume.

Suitable for

• Backpacking and hiking where natural water sources are used
• Travel to areas with uncertain tap water quality
• Emergency preparedness and disaster kits
• Day trips, cycling or short excursions requiring lightweight filtration

Key specifications

• Capacity: 1 litre reservoir
• Filter technology: hollow-fiber membrane
• Target contaminants: bacteria and protozoa (microbial removal)
• Maximum flow rate: up to 2 litres per minute (when squeezed)
• Reservoir type: flexible, squeezable bottle
• Weight and portability: lightweight, compact for travel and backpacking
• Maintenance: cleanable by shaking or backflushing

How to use

Fill the flexible reservoir from a water source, attach the filter to the reservoir opening, and squeeze the reservoir to force water through the hollow-fiber membrane into a drinking container or directly from the outlet. Avoid drawing very silty water directly through the filter without pre-filtering; allow heavy particulates to settle or use a cloth pre-filter. Perform routine cleaning by shaking or backflushing to maintain flow rate and prolong filter life.

Usage recommendations

Use the Katadyn 8021402 primarily to reduce microbiological contamination (bacteria and protozoa). It is not intended to remove chemical pollutants, heavy metals or viruses. Pre-filter turbid water to reduce clogging, store the reservoir and filter dry when not in use, and follow regular cleaning procedures to ensure consistent flow and filtration performance.
