TDS and AQI figures on this page are indicative planning ranges compiled from publicly reported patterns for this city — not live readings. Actual values vary by locality, borewell depth and season. Test your own supply with a TDS meter (around ₹300), and get a laboratory analysis if you suspect arsenic, fluoride, nitrate or iron.
Gangtok sits in a specific water-quality situation, and buying the wrong purifier for it is the most common and most expensive mistake households here make. Local supply typically runs 100-280 ppm TDS.
Most of Gangtok draws on treated municipal supply drawn from surface sources such as rivers, lakes and reservoirs, and local water is generally soft.
As a tier-4 city, Gangtok has a further consideration that spec sheets ignore: service reach. A purifier nobody local can repair is a worse purchase than a simpler one with a technician in town, which is why our recommendations here weight service network heavily.
Ranked for Gangtok's specific water profile — 100-280 ppm TDS, soft water, with service-network reach weighted heavily for a tier-4 city.

Tip
Whatever you buy, the ownership experience in Gangtokwill be decided by servicing rather than specifications. Before you order, phone the brand's customer care with your Gangtok pin code and ask how many days a filter-change request takes. If the answer is more than two or three days, choose a different brand.
If you are specifying water for an office, a housing society or a factory in Gangtok, a domestic purifier is the wrong tool — it will run continuously, exhaust consumables in a fraction of their rated life, and typically fail within 18 months. Commercial systems start at 25 LPH for a small office and scale to multi-thousand LPH industrial plants.
Given Gangtok's feed water at 100-280 ppm and soft hardness, pre-treatment requirements are comparatively modest, which keeps both capex and membrane replacement costs down.
