I did not sign up for or want reoccurring purchases. Will decide when I need more filters.

It makes noise

My last pleated filters didnt make any noise. This one makes a bit of a whistling noise when the air handlers running. Not enough to be annoying, but I wonder if its indicative of a longer term problem?
