4, 5 or 6 Stages RO/DI Unit?

[dennster]

Seeking opinion on whether is it necessary to get a 5 or 6 stages RO/DI unit as compared to a 4 stages, since our tap water is relatively clean.

Depend on ur budget. 4 to 5 stages is gd enough already.

Some bros even use 3 stages.

Any experience with just RO unit? Seems like it also able to achieve 0 TDS.

NTUC bottled water works too right ?

Hmmm probably not. Bottled water tends to come from natural sources so there may be some interesting elements inside. If you want to go the bottle water route then use distilled water.

On the original question of RO or RODI then this depends on what you aim to keep? what filters you are using? How often you plan on doing water changes? The RO may clear out most of the contaminants but often heavy metals are left over and this is where the DI comes into play. Even if you have heavy metal in the ppB range it can still have a big impact.

Luckily Singapore tends to have good quality water. But your building may have older pipes. So you never know unless you do an ICP test for your property.

Hope this helps

That is great. Can you tell more about your system, what filters and DI do you have?
