...powder on them? I just bought the A Plus pre filter and when I unfolded it I noticed it has white powder on the entire inside surface. The box says nothing of a white powder, but it does say "deodorizes", so it might just be an odor reducer. I tried calling the company but they are closed on weekends, so i'll have to wait til monday unless anyone else out there has had this experience or knows what it is.
Thank you!
