Worksheet Change event ignore change event

Okay, I know I've got a contradiction here; it's obvious I need help.

The situation: Cells E1:E3 are dropdowns for the Division, Program Area, and Account. The user picks his Division, whereupon my macro determines the available Program Areas. The user picks Program, whereupon my macro determines the available Accounts. User picks the Acct, my chart populates. All of this happens through autofilters and change events. What I want to happen is if there's a change in E1 (Div), I want to clear E2:J2 and E3:I3. But I DON'T want those "clearances" to show as change events, because I want to capture the subsequent action in E2 (Prog) and E3 (Acct).

The problem: Any change in E1 triggers a change in E2 and E3, so those macros run also I'd like to somehow run the macros only when my user makes a change, not when the automation clears the cells. In other words, I don't want Filter2 and 3 to run when I change E1, and I don't want the Filter 3 to run when I change E2. Any ideas how I can go about doing that?

My current code is posted below. Since this involves multiple sheets I didn't provide an example. If one is required for this please let me know.

Any help is greatly appreciated.

Thanks,
John
