Katadyn Combi Water Filter

Katadyn Combi Dual-Stage Ceramic and Carbon Water Filter

A dual-stage water filter combining ceramic and activated carbon. The Katadyn Combi removes bacteria, protozoa, and disease-causing agents through 0.2 micron ceramic depth filter while activated carbon reduces chemicals and improves taste. Weighs 580g and delivers 1L/min output with capacity up to 50,000 litres depending on water quality. Suitable for extremely dirty water and daily use. Simple change to 1-stage operation using only ceramic without activated carbon.

Ceramic Depth Filter Removes Bacteria and Protozoa

The tried and tested ceramic depth filter removes bacteria, protozoa, and other disease-causing agents. Micro-organisms cannot pass through the 0.2 micron pores because of their size. The ceramic can be cleaned repeatedly to restore flow rate, extending filter life in extremely dirty water.

Activated Carbon Reduces Chemicals and Improves Taste

The replaceable activated carbon reduces chemicals and improves taste and odour. The carbon removes chlorine, pesticides, and organic compounds. This makes water more palatable for drinking at camp or during motorhome travel.

50,000 Litre Capacity for Long-Term Use

The ceramic filter capacity reaches up to 50,000 litres depending on water quality. This exceptional capacity makes the Combi suitable for daily use, emergency preparedness, and temporary home use. The ceramic can be cleaned and reused throughout its lifespan.

Dual-Stage or Single-Stage Operation

The system operates in dual-stage mode with ceramic and activated carbon or simple 1-stage mode using only ceramic. Single-stage operation extends activated carbon life when chemical reduction is not needed. This flexibility proves valuable for varying water sources.

1 Litre Per Minute Output

The filter delivers approximately 1L/min output. This flow rate provides sufficient water for small groups up to 3 people. The consistent output makes filling water bottles and containers efficient at camp.

Suitable for Extremely Dirty Water

The ceramic depth filter handles extremely dirty water from rivers, streams, and lakes. The cleanable ceramic removes sediment and turbidity before water reaches the activated carbon. This proves valuable when camping in Scottish Highlands, Welsh valleys, and UK locations with turbid water sources.

Versatile Use from Backcountry to Motorhome

The Combi moves effortlessly from backcountry to motorhome, global travels to hikes, emergency use to temporary home use. The 50,000L capacity and cleanable ceramic make this suitable for extended expeditions and daily use. The replaceable activated carbon ensures chemical-free filtering throughout the filter life.

Activated Carbon Replacement After 400 Litres

The activated carbon should be exchanged after 2 fillings or 400 litres. Replacement cartridges are available separately. The ceramic continues filtering after carbon replacement, maintaining microbiological protection.

What Katadyn Combi Water Filter Does Best

The Katadyn Combi excels at providing long-term water filtration with dual-stage protection. The 50,000L ceramic capacity handles extremely dirty water with cleanable filter, the activated carbon reduces chemicals and improves taste, and the dual-stage or single-stage operation provides flexibility. At 580g, this provides comprehensive filtration for daily use, emergency preparedness, and extended expeditions.

Katadyn Combi Water Filter Limitations

The filter does not remove viruses, which are rare in UK water sources. The 580g weight is heavier than ultralight squeeze filters.

Katadyn Combi vs Katadyn Vario vs Katadyn Pocket

The Katadyn Combi provides dual-stage ceramic and carbon filtration with 50,000L capacity weighing 580g. The Katadyn Vario provides dual-mode operation with 2000L capacity weighing 425g. The Katadyn Pocket provides ceramic-only filtration with 50,000L capacity weighing 550g. Choose Combi when you want dual-stage protection with long-term capacity.

Katadyn Combi Water Filter Common Questions

What is the difference between dual-stage and single-stage operation?

Dual-stage uses ceramic and activated carbon for microbiological and chemical filtration. Single-stage uses only ceramic for microbiological filtration, extending carbon cartridge life.

Does this remove viruses?

No, the 0.2 micron filter removes bacteria and protozoa but not viruses. Viruses are rare in UK water sources. For virus protection, use water purification tablets as backup.

How do I clean the ceramic filter?

The ceramic filter can be cleaned by scrubbing with a brush or scouring pad. This restores flow rate when the ceramic becomes clogged with sediment.

How long does the ceramic filter last?

The ceramic filter capacity reaches up to 50,000 litres depending on water quality. The ceramic can be cleaned repeatedly throughout its lifespan.

When should I replace the activated carbon?

Replace the activated carbon cartridge after 2 fillings or 400 litres. Replacement cartridges are available separately.

Can I use this for extremely dirty water?

Yes, the ceramic depth filter is designed for extremely dirty water. The cleanable ceramic removes sediment and turbidity effectively.

Is 580g too heavy for backpacking?

At 580g, this is designed for group camping, motorhome travel, and base camp use rather than ultralight backpacking. The 50,000L capacity justifies the weight for long-term use.

What is the difference between Combi and Pocket?

The Combi includes activated carbon for chemical reduction and taste improvement. The Pocket uses ceramic-only filtration. Both have 50,000L capacity.
