Searching for new DEF filter/5303604
I've been trying to find a source for a new DEF filter 5303604 and finding most on eBay. However, even tho the prices range from $42-$75 the dates visible on the packages range from 2014, 2016, 2019, and am wondering how important the manufactured date is for these filters.
Considering the filter material looks mostly like paper how long will any of these older filters hold up for 2-4 years in a wet solution?
Should these older dates be deleted from a serious purchasing list?
