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.
The right water purifier for Siliguri is determined by what comes out of your tap, not by which brand advertises hardest. Supply in the city typically measures 150-450 ppm TDS.
Most of Siliguri draws on municipal supply blended with borewell water, which is why TDS varies through the year, and local water is generally moderately hard.
Siliguri is well served by every major purifier brand, so you can choose on specification and price rather than on which company has a technician nearby.
Ranked for Siliguri's specific water profile — 150-450 ppm TDS, moderate water.

Whatever you buy, the ownership experience in Siliguriwill be decided by servicing rather than specifications. Before you order, phone the brand's customer care with your Siliguri 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 Siliguri, 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 Siliguri's feed water at 150-450 ppm and moderate hardness, pre-treatment requirements are comparatively modest, which keeps both capex and membrane replacement costs down.
