Membrane solutions?

[Spare time]

Has anyone ever used membrane solutions brand. I am not sure if there is actually a difference between different 100gpd membrane brands (if so please tell me). I was looking to add a second membrane.

I worked with RODI filters 40 years ago and have often heard Dow Filmtec are the best membrane one can buy.

I've never bench tested them myself.

I know dow is popular but I was curious if anyone can actually tell me why they are better than membrane solutions brand or if it's just simply because dow is well known.

How do the specs compare between the two brands?

I am also not a fan of the company Dow due to their PFAS situation so I'd like to not support them if I can but they probably make membranes for other companies.
