## Abstract

A method of assembling a canister filter system includes inserting a first filter component into a second filter component, and continuing the insertion until a first tab of either the first filter component or the second filter component contacts the other of the first filter component and the second filter component.

## Claims

### Claim at position 1

-10. (canceled)

### Claim 11

A method of assembling a canister filter system, the method comprising:
inserting a first filter component into a second filter component; and
continuing the insertion until a first tab of either the first filter component or the second filter component contacts the other of the first filter component and the second filter component.

### Claim 12 (depends on 11)

The method of claim 11 wherein the first tab of either the first filter component or the second filter component slides into a first slot of the other of the first filter component or the second filter component.

### Claim 13 (depends on 12)

The method of claim 12 wherein the first tab slides upwardly in the first slot until the first tab reaches a ramp portion of the first slot.

### Claim 14 (depends on 13)

The method of claim 13 wherein the first filter component or the second filter component is rotated, causing the first tab to slide along the ramp portion of the first slot until the first tab reaches a circumferential portion of the first slot, causing the first filter component or the second filter component to contact a seal.

### Claim 15 (depends on 14)

The method of claim 14 wherein the first filter component or the second filter component is rotated until the first tab reaches a stop or a detent notch.

### Claim 16 (depends on 15)

The method of claim 15 wherein the first tab slides upwardly or downwardly in the detent notch.

### Claim 17 (depends on 15)

The method of claim 15 further comprising attaching the first filter component or the second filter component to a third filter component, providing a seal.

### Claim 18 (depends on 15)

The method of claim 15 further comprising inserting a second tab of a third filter component into a second slot of the first filter component or the second filter component until the second tab reaches a ramp portion of the second slot.

### Claim 19 (depends on 18)

The method of claim 18 further comprising rotating the first filter component or the second filter component until the second tab slides along the ramp portion of the second slot, reaches a circumferential portion of the second slot, and continues until the second tab reaches a second stop or a second detent notch.

### Claim 20 (depends on 19)

The method of claim 19 wherein the second tab slides upwardly or downwardly in the second detent notch.
