Title: Not worth it
Review: I bought these on the advice of my husband's allergist. We put them in all our registers, expecting it to cut down on the dust. Didn't happen - there's been no difference in the amount of dust in our house and no difference in my husband's symptoms. These aren't expensive but not worth the time or trouble.
