An RO purifier (roughly ₹15,000-25,000) needs an inlet tap, a drain line, a power socket and enough pressure; most failures come from bad plumbing, not the machine.
For a 20-50 person office, a commercial RO of 25-50 litres per hour (roughly ₹25,000-50,000) or a hot-and-cold dispenser (roughly ₹15,000-30,000) is the usual answer.
For rented homes, a countertop purifier (roughly ₹15,000-22,000) avoids drilling; manual-fill models need no plumbing at all, while plumbed countertop units still need a tap connection.
A copper water purifier (roughly ₹16,000-28,000) is an RO or UV purifier with an added copper stage; buy it for the purification quality first and treat copper as a modest bonus.
