Quick Answer
To clean the Sawyer Mini filter for optimal performance, backflush the filter with water at least once a week and more often if used in turbid water. Use a squeeze bottle to force water through the filter in the opposite direction of normal use. Allow the filter to air dry before reassembling.
Pre-Cleaning Instructions
Before cleaning, remove the filter from the housing and rinse it under running water to remove any visible debris. Use a soft-bristled brush to gently scrub the filter’s exterior and clean any clogged passages.
Backflushing the Filter
To backflush the filter, attach a squeeze bottle to the filter’s input port and fill it with a minimum of 4-6 ounces of water. Hold the filter upside down and attach a syringe or a hose to the filter’s output port. Squeeze the water through the filter in the opposite direction of normal use for 5-7 seconds. Repeat this process 2-3 times to ensure the filter is clean.
Air Drying and Storage
After backflushing, allow the filter to air dry by holding it upside down and placing it in a well-ventilated area. Do not submerge the filter in water or use a towel to dry it, as this can cause damage to the filter’s membranes. Once the filter is dry, reassemble it and store it in a clean, dry environment to maintain its effectiveness.
