Bought this replacement filter on December 18, 2016. By the end of January 2017, it is covered in mold, although claims to be "Protec antimicrobially treated to help inhibit the growth and migration of mold, algae and bacteria on the filter."  I expect a filter to last through the winter, not 6 weeks!
