Ensure each stage of filter stays at reasonable consumption for different raw water. For example, unpleasant taste raw water consumes more carbon adsorption space. Cloudy raw water consumes more PP screen. Reasonable consumption based on the real situation you meet. First Stage : PP Screen The purpose of PP screen is to remove visible particles and colloidal suspension. If the raw water is not cloudy and you would like to improve the flow rate, PP screen can be taken away from the water filter. There are 5pcs of PP screens as a standby. Second Stage: 0.1micron Ultrafiltration Mambrane Filter miniwell L605 uses 0.1 micron ultrafiltration membranes as filter media. Ultra-low pressure membranes ensure fast flow rate. Third Stage: Carbon Fiber Filter Miniwell Carbon Filter can reduce heave metal, such as Lead, Mercury, and Cadmium. 90% removal rate of chlorine can last 500L for municipal tap water. Miniwell carbon filter effective time is longest in such small volume. Water tastes great after filtering.

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 cant 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 cant 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, its 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 cant be used for salt water. A: Please
