The Eheim filter may not work after cleaning due to a few reasons. One common reason is that the filter media was cleaned too thoroughly, removing beneficial bacteria essential for the filtration process. Another reason could be that the impeller or other internal components were not reassembled correctly after cleaning, causing a disruption in the filter's functioning. It is also possible that the filter was not primed properly after cleaning, leading to a loss of suction and reduced filtration efficiency. **

One can filter or purify water using various methods such as boiling, using a water filter, adding chlorine or iodine, using UV light, or using a water purification tablet. Boiling water is one of the most effective methods to kill bacteria, viruses, and parasites. Water filters can remove impurities and contaminants from water, making it safe to drink. Adding chlorine or iodine can also kill harmful microorganisms in the water. UV light can be used to disinfect water by destroying the DNA of microorganisms. Lastly, water purification tablets can be used to kill bacteria and viruses in the water. **

Moisture can harm the screen when cleaning it, especially if it seeps into the device through the edges or openings. Excessive moisture can cause damage to the internal components of the screen, leading to malfunctions or permanent damage. It is recommended to use a minimal amount of moisture when cleaning the screen and to avoid getting moisture into the device. Using a slightly damp microfiber cloth is usually safe for cleaning screens without causing harm. **

A mechanic or an automotive technician would likely have experience cleaning a filter on a fuel pump.
