I've just bought a membrane from these https://www.ebay.co.uk/str/industrialwaterequipment my present one is reading 015 and coming out of the DI it's 005. I'll exhaust them both before putting the new membrane in. To be honest I didn't get much life out of the present membrane, possibly about a year but I don't change the pre filters often enough. I know I should but I'm lazy  ;D

I bought a spectrum for 199 off ebay the other week it's coming out at 5 after Ro  and before di.

The last cheaper one i bought only lasted 9 months and it was 9 after RO when new..

I’ve had Axeon HF5 membranes for years, but something has happened to the quality of them. They used to last 4-5 years, now they last about a year. Annoying.

So, this time I got a spectrum hf4 membrane from window cleaning warehouse. It’s about half the price of the Axeon, and even  if it lasts a year I’ll still be better off.

Currently it’s coming out at 2ppm (been using it for a week)
