Here's a good list of Mother's Day Gifts...http://www.goodhousekeeping.com/holidays/mothers-d...

Air filters are not included in this list, and it's a good thing.  But after Mother's day it would be a nice gesture to change your Mom's air filters in the house so she has clean fresh air.  It's just one less chore she would have to do, and our Mom's deserve a break every now and then.
