Product review (1 stars): Shipped in an open ziploc bag
I ordered this item and it shipped without issue. However, when I got it I was very surprised to see what I got: it came in a taped envelope. Inside, I found the filter stuck in a ziplock that didn't even close!!!! Needless to say, I will be contacting the seller as soon as I finish this review!!!

Update: Contacted immediately by representative of company and that person explained what they do. Thank you for the quick response!
