Multi-Stage Filter, A Filtration System Containing Such Filters, and Methods of Using the Systems

A multi-stage filter for filtering and transferring fluids comprising:

• (1) a filtering base comprising:
• (i) a cover comprising a first end having an opening, a second closed end opposite the first end, a body portion that extends between the first end and second end, and a housing formed within the body portion;
• (ii) a second stage filter positioned inside the housing of the cover, the second stage filter comprising a first end, a second end opposite the first end, a body portion that extends between the first end and second end, and a housing formed within the body portion, the body portion of the second stage filter comprising a plurality of openings;
• (iii) a first stage filter positioned inside the housing of the second stage filter, the first stage filter comprising a body portion comprising a plurality of openings having a size that is larger than the size of the openings of the second stage filter;
• and
• (2) a fluid transfer cap that attaches to the first end of the cover of the filter base, the fluid transfer cap comprising:
• (i) a first closed end;
• (ii) a second end having an opening that is positioned opposite the first end;
• (iii) an annular skirt that extends between the first and second ends;
• (iv) an annular shaped barrier member positioned inside the annular skirt and spaced apart from the annular skirt, the annular shaped barrier member comprising a housing and an outlet located at an end opposite the first end of the cap;
• (v) a fluid inlet comprising an extension member that extends through a side of the annular skirt to the annular shaped barrier member, and an open channel formed through the extension member to allow fluids to flow into the housing of the annular shaped barrier member;
• and
• (vi) a fluid outlet that receives and distributes filtered water from the housing of the cover,
• wherein, when the cap is attached to the base of the device, the annular shaped barrier member extends into the housing of the first stage filter, and the first stage filter and second stage filter engage the base and fluid transfer cap so water flows through the plurality of openings to the fluid outlet.
