Water filter bottle Katadyn BeFree AC 0.7 L green — Katadyn, model 8021573

The Katadyn BeFree AC 0.7 L green is a portable water filter bottle designed for lightweight, on-the-go water purification. The bottle integrates a flexible reservoir with a BeFree filter element that includes activated carbon to reduce particulate matter and improve taste and odor. With a 0.7-liter capacity and a packable design, it is intended for single-person use during hiking, travel, and emergency situations where access to treated water is limited.

Advantages

The integrated BeFree filter with activated carbon provides basic removal of sediment and improves water taste and smell without adding significant weight or bulk. The soft, flexible bottle packs down when empty for compact storage and is easy to fill from natural sources or taps. The wide-mouth design speeds filling and cleaning, and the filter is removable for backflushing to restore flow rate. Materials are BPA-free and the bottle is made for repeated outdoor use.

Suitable for

• Day hikes and backpacking where lightweight filtration is required
• International travel and transit through areas with uncertain tap water quality
• Emergency preparedness kits and disaster response situations
• Campsites and outdoor activities with access to lakes, rivers, or streams

Key specifications

• Capacity: 0.7 liters
• Filter type: BeFree hollow fiber element with activated carbon
• Contaminant focus: particulate reduction and taste/odor improvement
• Material: flexible, BPA-free reservoir
• Design: collapsible/packable bottle with wide mouth
• Intended use: personal, single-user portable filtration

How to use

Fill the bottle from a water source such as a stream, lake, or tap using the wide mouth. Drink directly through the bite valve or squeeze the soft bottle to force water through the BeFree AC filter. To maintain flow rate, periodically remove the filter and backflush by filling the bottle and squeezing clean water through the filter in reverse until flow improves. Follow manufacturer guidance for filter replacement intervals based on water quality and usage frequency.

Usage recommendations

For best performance, avoid filtering cloudy or heavily sediment-laden water without pre-filtering. Use the activated carbon-equipped BeFree filter primarily for improving taste and reducing chlorine and organic taste/odor; it is not intended to remove viruses or chemical contaminants. Regularly clean the bottle and allow components to dry before storage to prevent biofilm formation.
