Abstract
The container is made of a single blow molded piece having a pair of vertical column chambers, inlet and outlet connectors and tubes connecting the inlet and outlet connectors to circulate fluid through the vertical column chambers in series. Each container is filled with a recyclable filter medium and the container can be recycled with the filter medium. When the filter container is replaced, the entire filter container is sent for recycling. The filter container can be attached to other filter containers to form a compact filter assembly or the container can be mounted to a wall to be stored out of the way. When the containers are connected together, they can be arranged to be easily connected in series and when replacing spent filter containers, it is possible to replace only some of the containers connected in series to leave partially spent containers in the fluid circuit for further use while new containers are added to an outlet side of the containers connected in series.
