FAQ
Q: How often do I need to backwash the system?
A: It depends on the quality of the water source. When you feel the flow rate slows down, backwash can improve the flow rate. (Note: To extend filter life, always use the best freshwater source you can access. If raw water is cloudy, wait for the sediment to settle out until water appears clear and then filter the water above the sediment.)
If the flow rate is still slow after backflushing and you need clean water urgently, please remove the PP screen and carbon filter. Using a UF filter only in the L605 filter can speed up the flow rate. Although water taste can't be improved without carbon filter, the UF filter ensures essential safety.

Q: Can I use water filtered from the system itself to backwash the filter?
A: Yes. Filtered water from the filter can be used to backwash. Collects filtered water by a clean disposable bottle. Squeezes clean water into the filter from the water outlet

Q: How do I know its time to replace the filter?
A: Firstly, the water flow rate is still slow after backflushing, you can replace the PP screen.
Secondly, you feel the unpleasant odor can't be removed by carbon filter, you can replace carbon filter
Finally, if you backflush the filter a couple of times and water flow rate still very slow, it's time to replace UF filter.

Q: Does it filter salt water?
A: No. Miniwell L605 filtration pore size on the membrane is 0.1 micron. Dissolved salt passes through 0.1micron membrane. In other words, Miniwell L630 keeps mineral from nature fresh water sources in filtered water. Miniwell filters can't be used for salt water.
