It is highly recommended to place such a filter at the inlet of a high pressure cleaner. After a short time already you can see what all comes through the water line ... Easy to use and easy to clean, easy on the pressure washer. I've installed a few centimeters garden hose between the high pressure cleaner and filter so that the filter is not screwed directly onto the cleaner (not practical and sensitive to shock). Fixed with a cable tie in addition to the cleaner solution is ok.
