Looking for a membrane replacement other than Spectra for my Ventura 150.

See this thread.

Applied Membranes did well for us (we have a 200T), but also check Amazon and other online sources, the Dow/Filmtec membranes are very available.

Be careful with the Amazon ones, read the reviews, especially about the dry membranes.
I’ve recently found out that anybody’s membrane has a shelf life of one year from date of manufacture, that’s it. It’s due to the lifespan of the pickling solution, and none were dry to start with, they may dry out as they get old, and a dry one is very likely a bad one.

So don’t buy from anyone that is unwilling to communicate the date of manufacture with you before you buy.

Yep, as with expired food and many other items, you have to use care with online purchases, try to find reputable dealers. And membranes don't have much of a shelf life uninstalled, about a year is all you get without some extraordinary care.
