Chloramine filters

[DV2027]

My water dept now uses Chloramine to disinfect the water. Do the tradition 5 stage ro/di filters adequately remove the Chloramine or do I need the chlorplus carbon block?

A 5 stage working properly should be removing everything to unmeasurable levels(0 TDs.)

Thanks, I figured it would work but wanted to verify.

A TDS meter cannot detect chloramine (NH2Cl). TDS meters only detect ions.

That said, most 5-stage units (the carbon blocks) can handle chloramines (but will need replacing much sooner than usual). But it's certainly safer to get some catalytic carbon and the specialized carbon blocks.
