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.

Two Filters, Quick and Easy
Size: 16-23 Tacoma, Size: 16-23 Tacoma
The RVgolf Engine+Cabin Air Filters Kit for the Toyota Tacoma V6 comes with two air filters. There is a cabin air filter that fits nicely into the compartment accessed through the glove box and an engine air filter that dropped in easily in the compartment under the hood. Replacement of both filters was easy, didn’t require any tools, and it took more time to empty and replace the items in the glove box than it did to replace both filters. The Toyota dealership quoted me $80 to replace the cabin air filter only. I replaced both filters for less than $30. The filters felt like they were good quality. The engine air filter is multi-layered, with a thin foam layer to keep larger debris from blocking the finer paper filter. The cabin air filter said and looked like it had a carbon layer to absorb smells. The only concern I had was size. After I had replaced both filters I went to slide the engine air filter I replaced into the RVgolf box to throw it away. The engine air filter I replaced would not slide into the RVgolf box. It was too big. After driving for a few days and a couple of hundred miles, I popped the hood and checked the fit of the engine air filter. The fit looked perfect. See attached photos.

Fits 2019 accord (gas engine)
Size: 18-22 Accord
Dealer was going to charge almost $200 to change both of these filters in my 2019 accord. These filters fit perfectly and of same quality as the dealer product. Easy to install, saving me lots of money.
