Hi guys, I have a Kent Marine Hi-S Maxxima RO unit and need cartridges. How would I go about finding out if yours fit (may need membrane too)?
Are the cartridge sizes universal?
Also, mine consists of a 1Micron sediment cart, activated charcoal/ carbon cart, and post membrane di polishing cart.
Is this the way forward? As I see it most units dispense with the polishing cart and have another carbon cart instead.
TIA
PS. I have a salt based softener feeding this unit

Have a look at osmotics website and if you get stuck email them, there very helpful.
As far as I know the prefilters and membranes are a universal size.

Sediment, carbon, membrane and di resin/polishing cart. That is how you want it, replacing the di resin with a carbon filter is not a very good idea, after the membrane you will still have about 15 tds depending on your setup, the di resin brings that down to 0 tds, ideally you want a inline tds meter after the membrane and after the di pod to make sure it’s zero after the di and change the resin as soon as it goes to 1 tds.

A carbon filter after the membrane will do next to nothing.

That’s fine with the softener feeding it, it will lengthen the life of you membrane slightly, only downside is you will get through more softener salt.

Yes just refill it with new resin once it’s spent.
The sebiment filter takes out larger dirt particles and the carbon takes out chlorine among other things, if those 2 things go through the membrane it will reduce the life of the membrane, so there a must.
There’s no harm in adding more but it’s just more expensive having to replace them every 6 months.
