By use case
Apartment water has a specific problem: you are not connected to one source. Most Indian societies blend municipal supply with a borewell and top up with tankers when either falls short, which means your TDS is a moving target and nobody in the building can tell you what it is this week.
That argues for two things. A TDS controller, so you can adapt as the blend changes rather than being locked to one ratio. And a membrane rated above the worst case, because designing for the average leaves you unprotected in summer.
The second apartment constraint is space. Kitchens in flats are compact and the wall above the sink is contested. The Aquaguard Ritzy NXT and Delight NXT are the most space-efficient full-RO units here; an under-sink unit is the answer in a modular kitchen; a countertop unit is the answer if you cannot drill.
One thing worth raising with your society: if the whole building is on high-TDS borewell water, a society-level RO plant is dramatically cheaper per litre than 80 households each buying and servicing their own purifier. We size and quote those — the enquiry form goes straight to the commercial team.
