The Real Number Is the Yearly Cost, Not the Sticker
Every quote we send splits into three parts: the hardware, the installation, and the consumables that keep it honest. Hardware is the visible chunk — membrane, housings, storage tank, UV chamber. Installation covers fittings, bypass and drain plumbing and the commissioning hour where flow and pressure are set correctly. The third part is the one worth comparing hardest between offers: pre-filters that change two or three times a year, a membrane every couple of years, a UV lamp annually. A cheap system built around odd-size, hard-to-source cartridges costs more by month eighteen than a mid-range unit running on standard consumables.
So budget a yearly figure instead of staring at the purchase price. For a typical under-sink RO that means the unit plus roughly 400,000–900,000 IDR in filters and membrane wear per year; for UV, an annual lamp and a sleeve clean; for a whole-house chain, sediment and carbon changes paced by how dirty your source actually runs. Set against a galon-bottle habit of roughly 2.5 million a year, most drinking-water systems clear their own cost inside two years. The maths is boring — that is exactly the point.
Under-sink is enough when the complaint is drinking water: taste, scale rings in cups, distrust of the well. Whole-house treatment earns its price when symptoms show up across the villa — orange stains on tiles, scale killing the heater, an odour in every tap, or a rental where guests shower in water you would not drink. A fair rule of thumb: one problem tap, filter that tap; problems in every wet room, treat the line where it enters the house.
