Like any other filter, pocket filters also need replacement at a specified time in order to function well and be efficient in performance for the long run. However, pocket filter replacement is not free of cost, and especially, if you are not using it properly, chances are you end up with more frequent pocket filter replacement than expected and associated costs. Hence, using the pocket filter properly and taking care of its cleaning and maintenance needs reduce the number of pocket filter replacement instances.
Pocket filters are designed to eliminate bacteria and protozoan cysts like Giardia, Legionella and Cryptosporidium. The extend the ceramic life, the pocket filters should always be used with best water source available. Keep input pre-filter clean and off the bottom. In the heavy sediment cases, wrap the filter around the input pre-filter. Where possible, put untreated water in container, waiting for the sediments to settle down or until water seems clear. Then filter water above the sediment.
If the pocket filters pores of ceramic are closed or clogged, you must clean the ceramic. Never use force at the time of pumping. Unscrew pump base anti-clockwise from lower end of filter housing and them remove the plastic sleeve pulling it down. Clean ceramic element by brushing it with manufacturer’s cleaning pad until its original, light color appears. Take extra caution not to have unfiltered water touching filter output. Push plastic sleeve on the ceramic element. Lubricate slightly with silicone lubricant on the thread of pump base. Then tighten pump base clockwise.
Silicone lubricant is given with the new pocket filter. Unscrew handle collar on the topmost part of the filter element anti-clockwise and remove pump handle. Clean excessive build up from the black rubber on bottom of handle. Put small amount of lubricant on filter element thread and re-assemble.
