a dimple in either the filter unit body housing or the top of the tubular filter element; and a socket in either the filter unit body housing or the top of the tubular filter element that receives the dimple in either the filter unit body housing or the top of the tubular filter element to secure the tubular filter element to the filter unit body housing. ## Claims ### Claim 1 A filter securing apparatus, comprising: a filter unit including a frame unit; at least one tubular filter element positioned in said frame unit, said tubular filter element having a closed top and an open bottom; a dimple in either said frame unit or said closed top of said tubular filter element; and a socket in either said frame unit or said closed top of said tubular filter element that receives said dimple in either said frame unit or said closed top of said tubular filter element to secure said tubular filter element to said filter unit. ### Claim 2 (depends on 1) The filter securing apparatus of claim 1 wherein said dimple is located in said closed top of said tubular filter element and said socket is located in said frame unit to secure said tubular filter element to said filter unit. ### Claim 3 (depends on 1) The filter securing apparatus of claim 1 wherein said dimple is located in said frame unit and said socket is located in said closed top of said tubular filter element to secure said tubular filter element to said filter unit. ### Claim 4 (depends on 1) The filter securing apparatus of claim 1 wherein said frame unit is a triangular frame unit. ### Claim 5 (depends on 1) The filter securing apparatus of claim 1 wherein said frame unit is a square frame unit. ### Claim 6 (depends on 1) The filter securing apparatus of claim 1 wherein said frame unit is a trapezoid frame unit. ### Claim 7 A filter securing apparatus, comprising: a filter unit body housing; a multiplicity of tubular filter elements positioned in said filter unit body housing, said tubular filter elements having a closed tops and open bottoms; dimples in either said filter unit body housing or said tops of said tubular filter elements; and a sockets in either said filter unit body housing or said tops of said tubular filter elements that receive said dimples in either said filter unit body housing or said tops of said tubular filter elements to secure said tubular filter elements to said filter unit body housing. ### Claim 8 (depends on 7) The filter securing apparatus of claim 7 wherein said dimples are located in said tops of said tubular filter elements and said sockets are located in said filter unit body housing to secure said tubular filter elements to said filter unit. ### Claim 9 (depends on 7) The filter securing apparatus of claim 7 wherein said dimples are located in said filter unit body housing and said sockets are located in said tops of said tubular filter elements to secure said tubular filter elements to said filter unit. ### Claim 10 (depends on 7) The filter securing apparatus of claim 7 wherein said filter unit body housing includes a triangular frame unit. ### Claim 11 (depends on 7) The filter securing apparatus of claim 7 wherein said filter unit body housing includes a square frame unit. ### Claim 12 (depends on 7) The filter securing apparatus of claim 7 wherein said filter unit body housing includes a trapezoid frame unit. ### Claim 13 A filter securing apparatus, comprising: a filter unit including a frame unit; at least one tubular filter element positioned in said frame unit, said tubular filter element having a closed top and an open bottom; dimple means in either said frame unit or said closed top of said tubular filter element; and socket means in either said frame unit or said closed top of said tubular filter element for securing said tubular filter element to said filter unit. ### Claim 14 (depends on 13) The filter securing apparatus of claim 13 wherein said dimple means is located in said closed top of said tubular filter element for securing said tubular filter element to said filter unit. ### Claim 15 (depends on 13) The filter securing apparatus of claim 13 wherein said dimple means is located in said frame unit for securing said tubular filter element to said filter unit. ### Claim 16 (depends on 13) The filter securing apparatus of claim 13 wherein said frame unit is a triangular frame unit. ### Claim 17 (depends on 13) The filter securing apparatus of claim 13 wherein said frame unit is a square frame unit. ### Claim 18 (depends on 13) The filter securing apparatus of claim 13 wherein said frame unit is a trapezoid frame unit. ### Claim 19 (depends on 13) The filter securing apparatus of claim 13 further comprising a bolt connecting said at least one tubular filter element to said frame unit. ### Claim 20 (depends on 19) The filter securing apparatus of claim 19 further comprising an equalizer located on said bolt connecting said at least one tubular filter element to said frame unit. ### Claim 21 (depends on 20) The filter securing apparatus of claim 20 further wherein said equalizer located on said bolt connecting said at least one tubular filter element to said frame unit is a spring washer.
