ABSTRACT:
A liquid filtering apparatus includes a hollow cylindrical accommodation member having external screw threads at respective ends. Connecting members are disposed at respective ones of those ends, and each connecting member possesses a passage to enable liquid to flow through the accommodation member. Each connecting member is adapted to be connected to a water pipe and is retained on the accommodation member by a respective lid member which is threaded onto a respective end of the accommodation member. A filter disposed inside of the accommodation member is in the form of a cylindrical perforated net and a panel extending across one end of the net to resist radial crushing of the net when the filter is removed and is being cleaned.
