Versatile design: Easily setup a DIY filtration system by attaching on 28 mm thread soda bottle like Coca-Cola bottle, plastic bag, collapsible bottle or bucket. Or drink directly from water source like a straw. Backflushing with ease: A silicone gasket around mouthpiece helps to create air tight backow for backflush. Reliable filtering result: 0.1 micron membrane ensures 99.999999% removal rate of bacteria. TUV and SGS testing reports. Superior material: FDA approved. Impact resistance and ultra-light L630 fits in the palm of your hand. A great choice for camping, hiking, shing, scouting, travel, military, survival use, or emergencies.
Lifespan of filter can be extended by backwashing/backflushing. Backflushing can rinse away impurities that the membrane has filtered from water. We set a silicone gasket around the mouthpiece. A handy bottle can be covered on the gasket for backflushing without leakage. You don't need to keep a syringe on the go anymore.
When to backwash/backflush:
1) When the flow rate slows. Please use clean water on while back-ushing.
2) Before storing the miniwell water filter, backflush with clean water and then soak in a mild vinegar solution to disinfect the filter.
3) After cleaning, let the filter air dry and store in a cool and dry location.
4) Shelf Life: 5 years. After initial wetting: 3 years.
Accessories included 1) Miniwell personal water filter L630 with tip cap 2) Bucket or plastic bag connector 3) Hose clip 4) Silicone hose
Q: How often do I need to backwash/backflush the system?
A: It depends on how clean or dirty the source water is. When you feel the flow rate slow down, backwashing/backflushing can improve the flow rate. (Note: To extend filter life, always use the best fresh water source you can access. If raw water is cloudy, wait for sediment to settle out until water appears clear and then filter the water above the sediment.)
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. Collect filtered water by a clean disposable bottle. Squeezes clean water into filter from filter outlet.
Q: How do I know it's time to replace the filter ?
A: The filter will not allow water to flow when the filtration pores are blocked. If the water flow slows down or there is no water flowing out through filter, it is time to replace your filter.
Q: Does this work on E.coli and parasites like Giardia and Cryptosporidium?
A: Yes. Miniwell L630 is capable of filtering 99.9% bacteria and parasites.
Q: Can this filter remove unpleasant taste in raw water?
A: Hollow fiber can not remove unpleasant taste and pigment in raw water. L630 is the most basic filtration system for fresh water filtration with 99.9% removal rate of all bacteria. If you would like to improve the taste water, miniwell L610, L600, and L620 will better suit your needs.
Q: Does it filter salt water?
A: No. Miniwell L630 filtration pore size on the membrane is 0.1 micron. Dissolved salt passes through a 0 micron membrane. In other words, Miniwell L630 keeps minerals from natural fresh water sources.
