1. How often do I need to backwash the system?

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.)

2. Can I use water filtered from the system itself to backwash the filter?

Yes. Filtered water from the filter can be used to backwash. Collects filtered water by a clean bottle. Screw a clean water bottle on the filter water outlet. Invert and squeeze the clean bottle to backwash the filter.

3. How do I know its time to replace the filter?

No water flows out from the water filter even though you backwash the filter a couple of times. The filtration pores on the membrane are nearly blocked. It's time to replace the filter.

4. Does it filter salt water?

No. Miniwell L630 filtration pore size on 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.
