Well this was a waste of effort. They shipped me back 3 PureOne filters, not the new Ones they are now making. At least the date code was from February 2016, so they are new stock. But whether the tear issue was fixed on these by then, I can't say. I thought that fix was implemented with the new "One" filters. That said they fleeced me on UPS broker fees, as I had to pay $21 to receive the box. So basically I paid for the filters twice. This should have been covered under a warranty issue and with no charge. Why I'd have to pay any fee at all I don't know. $21 equates to $100 in filter costs, yet they quoted these filters as being only worth $6 each. So even the broker fee doesn't add up to what I paid. I won't be buying their filters again that is for sure.
