By use case
The most common and most expensive mistake in office water is buying a domestic purifier for a commercial load. A household unit is designed for perhaps 20 litres a day; put it in a 40-person office pantry and it runs almost continuously, its consumables fail in a third of their rated life, and it will be dead within eighteen months.
Size by headcount. Up to about 15 people, a good domestic RO with a 9-litre tank is genuinely adequate. From 15 to 40 people, you want a 25-50 LPH commercial system with a stainless-steel body. Above 40, you are into 100 LPH territory with proper pre-treatment, and above 150 people you should be planning a plant rather than buying an appliance.
Two other things that matter more in an office than at home. Hot water, because tea and coffee consumption in an Indian office is relentless. And an AMC with a defined response time, because a broken purifier in an office is an immediate productivity problem, not an inconvenience.
If you are sizing anything above 25 LPH, use the enquiry form — we will specify against your headcount and your actual water report rather than guessing.
