DUPONT FILMTEC™  TW30 PRO-2540 Commercial Reverse Osmosis Membrane Element

 Direct Replacement for FilmTec TW30-2540, which is now obsolete. 



DUPONT FILMTEC (Formerly DOW FilmTec) TW30 PRO-2540 Elements are the industry standard for reliable operation and production of the highest quality water in commercial applications. DuPont DOW FILMTEC TW30 PRO-2540 elements are tape-wrapped—built with the same high quality membranes and materials of construction as industrial elements, except for the hard outer shell, and are more economical for commercial systems with one or two elements per housing.



DuPont FILMTEC Brackish Water Reverse Osmosis Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. DOW FILMTEC RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations.



DuPont FILMTEC TW30 PRO-2540 is the direct replacement for TW30-2540 which has been discontinued by the manufacturer.

Flavored Water I Actually Crave
Flavor Name: Best Sellers Variety Pack, Size: 16 Fl Oz (Pack of 12), Flavor Name: Best Sellers Variety Pack, Size: 16 Fl Oz (Pack of 12)
I didn’t expect to get hooked on a flavored water, but Hint Water Watermelon has honestly become one of my everyday essentials. I usually get bored with plain water, but this hits that perfect balance, it’s just enough flavor to keep things interesting without feeling fake or overpowering. The watermelon taste is super light and refreshing, like a subtle hint of a fresh slice rather than that overly sweet candy version you get with a lot of drinks. I’ve tried a ton of flavored waters, and this is one of the few that doesn’t leave any weird aftertaste, which is a huge win for me. I find myself reaching for it throughout the day, especially when I’m trying to stay hydrated but don’t want soda or anything sugary. It just feels clean and easy to drink. At this point, it’s kind of replaced most other drinks for me. I always make sure I have a few bottles on hand.

good water
Size: 16.9 Fl Oz (Pack of 12)
I like to taste of this water And I feel like the quality is good. the size of the bottom is perfect for on the go. the water quality is good and it is refreshing. the water doesn't have a bad after taste. The only drawback would be the bottles are a little thin and you have to worry about the durability of them if stacking in the fridge because they could open from pressure. The durability of the bottles are lacking s bit.
