How often should you replace it?
Really it depends upon your diligence on the rest of your filters, and your water source quality... Carbon and Sediment should be replaced about every 6 months, and if you keep up with that maintenance your membrane can last 2 to 3 years even... Some filters have in line TDS meters to tell you when its necessary to change each individual filter... DI resin is a bit different, in that you have to replace it as often as it is depleted... They have color changing resin that changes from blue to brown/black once depleted... I have seen claims that sometimes it doesn't always change...
As a rule of thumb, for my RO/DI maintenance, I will change my Carbon and Sediment filters every 6 months... I will check my DI resin to see if it has changed color, but I will also test the TDS of my Product water monthly... If it is up to 3 TDS I will usually change my DI resin... If my TDS does not go back down to 0 and I have replaced all other filters along with my DI resin, then I will change my membrane...
I replaced my membrane last year, but I'm going to buy one because this is a ridiculous cheap price... If you buy it and store it, make sure that you do not open the sealed package... You will notice that it is damp/wet inside the package... If the membrane dries out, it is no longer any good...
will a Spectrapure membrane work in my Water General unit?
They will fit in all standardized RO and RO/DI units... Water General is one of the standard sizes, but there are some RO/DI's out there that make custom filters, so that you have to use their replacements...
I have MaxCap SP 5-stage so this is perfect for me. Spectra Pure tests each filter for optimum rejection ratio. I'm normally too cheap to buy one but at this price, count me in (if it is not too late)!
I'll likely be ordering by the end of the week, since there are limited quantities and do not want to miss out...
So with all that said-- I don't know, but I did find the sale before Randy.
Yes, Paul did find the sale, and thank you for passing it on...
Text me and remind me to do it tomorrow, ok?
Will do...
