Can we use ice cube machine without ro water ? what will be the TDS required for better quality for ice cube?
No we never recommended without ro plant. Because mostly according the ground water tds very and ice cube machine might be chocked because without filter ground water contains calcium, salt and other contaminations etc.
If you use filter ro water your ice quality will be improve along with look wise it look crystal clear. If you know about the tds, it shows the quality of your water stand for total dissolve solid and we recommended between 55-65 tds best for drinking purpose also.
