For customer who confuse for Dow and Dupont:
**The Dow Chemical Company (TDCC) in 2017, the company merged into?DowDuPont, and in April 2019, the company's parent,?Dow Inc., was separated into a?public company?via a?corporate spin-off. By the way, DowDupont was split into three publicly traded companies with focuses on?agriculture?(Corteva), materials science (Dow Inc.), and specialty products (DuPont). So for customer previously buying Dow brand, dont worry, they are same item, just only Filmtec RO Membrane Series now is fall under Dupont company, new series now all have the authentication code for verfication**
