Sawyer Mini, Micro and Squeeze – General Maintenance and Cleaning Guide
Sawyer water filters – Mini, Micro, and Squeeze – are highly effective and long-lasting when properly maintained. Regular cleaning and correct storage ensure good flow rate and extended filter life.
The filter should be cleaned at the latest when the flow rate slows down. It should also be cleaned after long periods of disuse. Rinsing the filter also moistens the internal membrane, allowing water to flow more easily. Clean the filter by pushing clean water through it using the cleaning syringe. Repeat until the water coming through is clear.
When to Clean?
– After use, especially if the water was turbid or the filter has been unused for a long time.
– If the flow rate slows down, the filter is likely clogged.
– Before long-term storage, such as over winter.
Backflushing
Supplies: Cleaning syringe and clean water
Steps:
1. Fill the syringe with clean water.
2. Attach the syringe to the clean water outlet of the filter.
3. Push water back through the filter in the opposite direction.
4. Repeat several times until the water coming out is clear.
Note: Do not use excessive pressure. If the filter is completely dry, moisten it first.
Disinfection (Long-Term Storage)
Supplies:
– 2 liters of water
– 1 capful of unscented bleach
– Cleaning syringe
Steps:
1. Mix bleach with water.
2. Push the solution through the filter using the syringe (2 liters).
3. Let it sit for a few minutes.
4. Rinse thoroughly with clean water.
5. Blow air through the filter using the syringe until no droplets come out.
6. Let dry in a well-ventilated area or store wet and clean before next use.
Vinegar Soak (Limescale Removal)
Supplies:
– Sawyer water filter (Mini, Micro, or Squeeze)
– White vinegar
– Clean container
– Cleaning syringe
Steps:
1. Prepare solution: Mix 1 part vinegar and 1 part clean water (e.g., 100 ml + 100 ml). Use pure vinegar for severe clogging.
2. Soak the filter: Place the filter with the water inlet facing down into the container. Ensure it is fully submerged. Soak for at least 1 hour, overnight if needed.
3. Backflush: Remove the filter from the solution. Fill the syringe with clean water and push it through the filter in the opposite direction. Repeat until the water is clear.
4. Rinse thoroughly: Rinse the filter with at least 2 liters of clean water. Ensure no vinegar remains inside.
⚠️ Notes:
– Do not use vinegar regularly – only when needed for limescale or mineral removal.
– Do not use vinegar if the filter is damaged or has been frozen.
– Ensure the filter is fully rinsed before use.
