Reverse osmosis filter.

Hi and a Merry Christmas to you all.
I would like to get some opinions on the reverse osmosis filter in the following link. I know next to nothing about them and I value your opinions. It is a little cheaper than many others listed so I am concerned about the quality. Bare in mind that I am in Australia and everything is more expensive here.
Thank you in advance.

I'd go for an RO/DI unit by Spectrapure instead; they have really good quality in there units

 

Thanks for the reply. It seems I forgot about the DI. I had a look at the Spectrapue web site but there were no prices listed.
Would a three stage system be adequate. In particular the one in this link?

ummm WTF? the water can become TOO PURE to drink?!?!?! HOWS THAT EVEN POSSIBLE?!?! Well anyway it seems that that can work but again I'd still go with spectrapure. lemme just find you a link; they might have some specials right now.

Spectrapure CSPDI RO/DI system for only $200 dollars which is pretty good IMO. It's the three stage one; really good, and I speak from experience cuz I have it

 

So does any one know what it means "This is a marine aquarium reverse osmosis system and is not suitable for drinking water as it is too pure. " Is it holly water maybe ?

 

Those guys were probably on crack then XD

 

I cant remember exactly, but I think it had something to do with the ionizing. I think you body will not absorb it quite right. I saw a drinking water the other day that had a ph of 9 on it (got no clue what ph is good for humans) but it made me think we would not just put any water in out tank so what is the best water for us?

 

I think your body needs minerals in the water you drink. Kinda how the salt you use in the water you place in your tank contains trace elements. Would you use straight RO for a fresh water tank? No, they sell something called RO Right.

 

"Distillation removes all minerals from water, and the membrane methods of reverse osmosis and nanofiltration remove most to all minerals. This results in demineralized water which is not considered ideal drinking water. The World Health Organization investigated the health effects of demineralized water in 1980, and its experiments in humans found that demineralized water increased diuresis and the elimination of electrolytes, with decreased serum potassium concentration. Magnesium, calcium and other nutrients in water can help to protect against nutritional deficiency. Demineralized water may also increase the risk from toxic metals because it more readily absorbs them, and because the presence of calcium and magnesium in water can prevent absorption of lead and cadmium.

So it is not just their RODI unit, RODI units in general are not recommended for human consumption because of the DI factor.
