What Apartments Need vs What Houses Need

An independent house or villa has a large kitchen, counter space, and often higher TDS borewell water — so a big floor-standing RO with 15L tank makes sense.

Apartments are different:

• Limited counter/wall space — compact form factor essential
• Municipal water — usually TDS 150–500 ppm (lower TDS than borewell)
• Smaller family size — 2-4 people, 8–10 litres/day usage
• No drain plumbing complications — standard wall-mount installation works

This means you need a compact wall-mount RO purifier, not a floor-standing model, and you don't need to pay for heavy-duty borewell-spec hardware.

Do Apartments with Municipal Water Need RO?

Short answer: Often yes, even for municipal water.

Municipal water in Indian metros is treated and has lower TDS (150–400 ppm typically), but it contains:

• Chlorine (disinfectant residue) — needs carbon filter
• Chloramines — carcinogenic over long-term consumption
• Heavy metals from old pipes (lead, copper leaching)
• Bacterial contamination during distribution (pipe leaks)

A UV purifier handles bacteria, but not dissolved chemicals and heavy metals. An RO handles both. For Indian apartments on municipal supply, an RO + UV combo is still recommended — the health protection is worth the ₹10,000–₹15,000 investment.

Exception: If you live in a building with stainless steel overhead tanks, modern PVC plumbing, and your TDS is consistently under 200 ppm, a UV purifier alone (₹4,000–₹6,000) may be sufficient. Test your TDS first.

Installation Tips for Apartments

1. Check your kitchen wall: RO purifiers need a standard wall plug (16A socket) and nearby drain pipe connection. Most kitchens have both.
2. Drain connection: The reject water outlet connects to your kitchen drain pipe — no separate drainage needed.
3. Installation time: Standard RO installation takes 45–60 minutes. Most brands include this free of charge.
4. Inlet connection: Taps into your main kitchen tap water line — no plumber needed beyond the brand's technician.
