A clean filter is a fast filter. Over time, sediment and debris clog the hollow-fiber membranes in your microfilter and slow your flow to a trickle — backflushing, often called backwashing, reverses that, pushing clean water back through the element to clear the buildup and restore performance. Backflush early and often to preserve both the flow rate and the lifespan of your filter. Cana Provisions carries everything you need to keep your system flowing: medical-grade 60mL catheter-tip backflush syringes, syringe retainers to keep the tool with your kit, and accessories to adapt to your setup. Compatible with Sawyer, Platypus, MSR and other standard microfilters, our backflushing gear is a small investment that dramatically extends the life of the filter you already own.
