Extra container's legs 204 stand on the filter 300 and press it down to main container's interior bottom 405. A sieve 100 is placed on top of the extra container 200. Sieve's handles 104 lean on extra container's rim 201. a fast-flow washable filter 300 may be used. Additional containers 200, filters 300 and sieves 100 can be added. Structure and materials allow fast drainage of fluids. All materials are washable, durable and reusable. All parts are removable and replaceable.
