Excel 2013 :: Filtering Data For Mailing Label

I'm having trouble filtering a large list of 900 names to create mailing labels for anon-profit organization. For years I have been using Microsoft Works to create these labels, however, the people now doing the membership insist on using Excel. I have Office 2013 and am using Excel 2013 on a new Dell PC using Windows 7. I have partially solved the problem but have one hang up.

I got to a point where I could filter out the dates and a couple of other items, but can't seem to get the last two. I was able to get the minimum date (equal to or greater) than 2012 to filter and the (equal to)LIFE (life membership) one and the (equal or greater than) ID# of 9000to filter by changing the cell format in all of those columns of cells to "text" instead of "general", BUT I still can't get it to (be blank) for the M column which houses a "D" or "U" (indicating deceased or uninterested) and an E column which houses an "E" if the person receives the newsletter electronically rather than by mail.

My fieldset up is:

To Year is equal or greater than 2012
Or M Class is equal to LIFE
Or ID# is equal or greater than 9000
And M is blank
And E is blank

The first three work but the last two do not seem to filter properly.
