The filter includes (a) a manifold having an inlet and an outlet; and (b) a main filter body connected to the manifold. The main filter body includes a flow disrupter, the flow disrupter comprising a tiered plate assembly arranged in the filter body and each plate in the tiered plate assembly comprises an arrangement of apertures. The inlet of the manifold, the tiered plate assembly, the outlet of the manifold and a bottom of the main filter body define a flow path for fluid to be treated. ## Claims ### Claim 1 A filter for removing magnetic and non-magnetic particles held in suspension by a fluid, the filter comprising: a. a manifold having an inlet and an outlet; b. a main filter body connected to the manifold, wherein the main filter body comprises a flow disrupter, the flow disrupter comprising a tiered plate assembly arranged in the filter body, wherein each plate in the tiered plate assembly comprises an arrangement of apertures, wherein the inlet of the manifold, the tiered plate assembly, the outlet of the manifold and a bottom of the main filter body are configured to define a flow path for fluid to be treated, the flow path entering through the inlet of the manifold, passing into the filter body and down through the apertures of the tiered plate assembly, and passing the bottom of the main filter body which is configured to collect the magnetic and non-magnet particles removed from suspension in the. fluid to settle into the bottom of the main filter body, and the flow path being redirected hack up through the tiered plate assembly to exit through le outlet of the manifold; and wherein the filter does not contain a magnet. ### Claim 2 (depends on 1) The filter according to claim 1, wherein the tiered plate assembly is fixably attached to a bolt, wherein the bolt is secured to a top inner surface of the main filter body. ### Claim 3 (depends on 2) The filter according to claim 2, wherein the bolt comprises a threaded end that is threaded into a corresponding recessed opening at the top inner surface of the main filter body. ### Claim 4 (depends on 2) The filter according to claim 2, wherein the tiered plated assembly comprises at least a top tier and a bottom tier arranged around and joined to a cylindrical tube, wherein the bolt is fitted through the cylindrical tube to attach the tiered plate assembly to the main filter body. ### Claim 5 (depends on 4) The filter according to claim 4, wherein the top tier comprises an upper plate and a lower plate, wherein the upper plate has a smaller diameter than the lower plate. ### Claim 6 (depends on 4) The filter according to claim 4, wherein the bottom tier comprises at least two plates. ### Claim 7 (depends on 5) The filter according to claim 5, wherein the upper plate of the top tier comprises an outer edge and a plurality of equidistant spokes that connect the out-r edge to the cylindrical tube, whereby a plurality of apertures are created. ### Claim 8 (depends on 5) The filter according to claim 5, wherein lower plate of the top tier comprises an outer edge and a second concentric circle arranged equidistant between the outer edge and the cylindrical tube, wherein a first set of spokes connect the outer edge to the second concentric circle to create a plurality of apertures and a second set of spokes connect the second concentric circle to the cylindrical tube, whereby a plurality of apertures are created. ### Claim 9 (depends on 6) The filter according to claim 6, wherein each of the plates of the lower tier comprises an outer edge and a second concentric circle arranged equidistant between the outer edge and the cylindrical tube, wherein a first set of spokes connect the outer edge to the second concentric circle to create a plurality of apertures and a second set of spokes connect the second concentric circle to the cylindrical tube, whereby a plurality of apertures are created. ### Claim 10 (depends on 1) The filter according to claim 1, wherein the manifold comprises a bypass hole, whereby flow through the main filter body is reduced. ### Claim 11 (depends on 10) The filter according to claim 10, wherein the manifold comprises a full bore valve to reduce fluid pressure loss within the filter. ### Claim 12 (depends on 1) The filter according to claim 1, wherein the main filter body comprises a top portion and a bottom portion and the flow disrupter is arranged in the top portion of the main filter body whereby, in use, when fluid to be treated enters the filter through the inlet of the manifold, the fluid passes into the top portion of the main filter body and down through the apertures of tiered plate assembly and into the bottom portion of the main filter body and is redirected back up through the tiered plate assembly in the top portion of the main filter body to exit through the outlet of the manifold, whereby particles held in suspension by the fluid are removed and settle into the bottom of the bottom portion of the main filter body. ### Claim 13 A method of treating a fluid to remove magnetic and non-magnetic particles from the fluid using a filter, wherein the filter comprises: a. a manifold having an inlet and an outlet; b. a main filter body connected to the manifold, wherein the main filter body comprises a top portion and a bottom portion and a flow disrupter arranged in the top portion of the main filter body, the flow disrupter comprising a tiered plate assembly, herein each plate in the tiered plate assembly comprises an arrangement of apertures, wherein the inlet of the manifold, the tiered plate assembly, the outlet of the manifold and the bottom portion of the main filter body are configured to define a flow path for fluid to be treated, the flow path entering through the inlet of the manifold, passing ow the ton portion of the main filter both and down through the apertures of the tiered plate assembly, and passing into the bottom portion of the main filter body which is configured to collect the magnetic and non-magnet particles removed from suspension in the fluid to settle into the bottom of the main filter body, and the flow path being redirected back up through the tiered plate assembly arranged in the top portion of the main filter body to exit through the outlet of the manifold, and wherein the filter does not contain a magnet; the method comprising the steps of: a) diverting fluid into the filter via a manifold inlet of the filter, wherein the fluid comprises magnetic and non-magnetic particles suspended therein;) b) flowing the fluid into the top portion of the main filter body and over and through tiered plate assembly from a top of the tiered plate assembly to a bottom of the tiered plate assembly and into the bottom portion of the main filter body; c) disrupting particles held in suspension by the fluid to direct the particles towards an area of low flow at the bottom portion of the main filter body; d) passing the fluid hack up through the tiered plate assembly from the bottom of the tiered plate assembly to the top of the tiered plate assembly and out of the filter via a manifold outlet of the filter; wherein particles held in suspension by the fluid are removed and settle into the bottom of the bottom portion of the main filter body. ### Claim 14 (canceled) ### Claim 15 (depends on 13) The method according to claim 13, wherein the bottom of the main filter body causes a change in the flow trajectories of the particles to settle into the bottom of the main filter body. ### Claim 16 (depends on 13) The method according to claim 13, wherein particles are also captured on surfaces of the tiered plate assembly. ### Claim 17 (depends on 13) The method according to claim 13 wherein the magnetic particles comprise magnetite particles and/or hematite particles. ### Claim 18 (depends on 13) The method according to claim 13, wherein the particles are filtered from a fluid in a hydronic heating or cooling system. ### Claim 19 (depends on 18) The method according to claim 18 wherein the particles comprise system debris in the hydronic heating or cooling system. ### Claim 20 (depends on 1) A hydronic heating or cooling system comprising the filter of claim 1.
