Cleaning a Katadyn Hiker Pro Water Filter

Difficulty: Easy

How to:

Things You’ll Need:
  • Coffee filter
  • Silicone lubricant
  • Water
  • Soft brush
  • Bleach

To properly clean and maintain your Katadyn Hiker Pro water filter, use the following steps. If your Katadyn Hiker Pro water filter isn't pumping, you should also follow these steps to see if cleaning will help. If not, you'll need to replace the filter cartridge.  


Step 1
Lubricate the pump's O-ring. If the handle becomes hard to pump, remove the handle collar and handle. Clean the black O-ring and lubricate it with silicone lubricant. Katadyn provides lubricant with each Hiker Pro. Reassemble and test. To make sure the O-ring doesn't dry out, do this before each camping trip.
Step 2
Clean the check valve. Remove the unit's filter and fill it halfway with clean water. Swirl the water around and dump. Repeat and replace the filter. Pump slowly to get the water moving again. In the field, if the unit pumps easily but no water is drawn, this will often fix the problem.
Step 3
Clean the pre-filter. Remove the pre-filter from the hose and disassemble. Gently brush the pre-filter to clean it. Then reassemble and reattach to the hose after wrapping it in a coffee filter.
Step 4
Disinfect before long-term storage. Add 2 tbsp. of bleach to one liter of water. Pump the solution through the filter. Continue pumping until all the remaining water has passed through the filter and hoses. Remove the cartridge and air dry. Because the bleach may flavor future filtered water, pump several liters of water before your next trip.
Step 5
Replace the filter. When the filter becomes clogged, try to clean it by swishing it around in the water. Make sure to avoid cross contamination of the output nozzle. 

When to Replace the Filter

If the filter still won't pump after following the above steps, it's time to replace the filter cartridge with a new one. In 2018, a new replacement element costs just over $45 from Amazon.

Tips & Warnings

Preventative maintenance helps extend the filter's life.
Use the clearest water possible when selecting a water source to filter.
Use the pre-filter's float to keep the hose out of the mud and off the bottom of the water source.
If possible, allow the sediment to settle out of dirty water before filtering or use a coffee filter wrapped around the pre-filter to help keep sediment out.
