Product review (1 stars): Does NOT fit Simpli Stik SD20000RED
I bought these as replacement filters with the Dirt Devil Simpli Stik SD20000RED. The amazon information page says these will fit SD20000RED and they do not.  I can use them for an older Dirt Devil Stik vac but already have replacements from a previous order for the older vac. I will keep these since I can use them, but am unhappy that you gave me misinformation. I'm still looking for allergen dust cup filter replacements for my new SD20000RED.
