I just googled it and seems to be about £35 for a new membrane, if it's just replacement filters you want they are a lot cheaper. Pretty sure most are universal though and any filters or membrane would fit, haven't had to replace mine yet so can't tell you for sure. It would be cheaper to buy new than have to replace all the membranes and filters, unless it's really cheap. Does it come with a TDS meter?
Thank you
I only have my phone to use and my google never shows helpful links! so hard to see them on my phone as well! getting my laptop back soon though!
Well I think I can get it for around £20 but it is 1 1/2 years old. Never changed everything but he said he used it every 2 weeks for W/C.
Membrane might be ok but I need to have a view to change it
