RO/DI and Chloramines

[Serioussnaps]

Since Im buying a new RO/DI unit I have been reading about them fairly thoroughly. Something has come to my attention and I am trying to grasp it. The water that I will be purifying is city water that is treated with CHLORAMINES. I have read that 4 stage units dont remove all chloramines and that if they do ammonia may be a byproduct that comes out in the water that will be used. I have also read the contrary which states that it generally removes chloramine and the ammonia is taken out before the output water is made by the membrane.

Which is true?
Should I worry about it?
How does this RO/DI unit look for this purpose?

Also and finally,

Will chloramines damage a unit that isn't all "suped" up to remove them?
Could I just make the water with a 4 stage unit like the one above and treat the water with a conditioner like Prime to remove the chloramines? Should i Just do this?


Thank you for your time to those that read this thread.

You can contact the folks at http://www.airwaterice.com and let them know your situation. They can set you up with a unit that will fit your needs. Make sure you go for a system that has the 75 gpd dow filmtek membrane.

I was thinking a 50 gpd dow filmtek like the one above. I have read that the lower GPD gives the water a longer contact time in the carbon that removes chloramines and also more contact time on the membrane. Is this right? Will a lower GPD help here?

I also have chloramine in my city water.

Maybe go with Optima CA from purelyh2o. Thats the system I own and after talking with Bryan I felt very confident with this purchase. It has a GAC catalytic carbon filter which is supposed to work better at removing chloramine. Reef central members get a 10% discount so it isn't much more than the one you were looking at.

www.purelyh2o.com The Optima CA is designed specifically for chloramines.
Any of the better reputable vendors can set you up with a system that will do the job. The secret is catalytic carbon which is a different product than GAC or carbon blocks.
