The checklist

  • CADR: pick a CADR of at least 250 m³/h for a bedroom and 400 m³/h for a living room in a polluted city.
  • Filter: a true HEPA H13 filter plus activated carbon handles PM2.5 and odours.
  • Running costs: replacement filters cost ₹2,000 to ₹6,000 a year, so check before you buy.

Set your budget

The air purifiers we researched sell for ₹9,000 to ₹50,000. Decide how you will use it first; the priciest model is often a skip for everyday needs.

India-specific tip

In Delhi NCR and other North Indian cities, run the purifier with windows closed during the October to February smog season, and replace the filter as the app or indicator suggests.

Before you buy an air purifier: the essentials

Buying an air purifier is easier once you know which three or four specs actually change your experience and which are just marketing. This guide covers exactly that for air purifiers sold in India, plus the budget to plan for, the local quirks to watch and the models we would buy today.

What to spend

The air purifiers we checked sell for ₹9,000 to ₹50,000. Below that range you usually lose durability or a key feature; above it, make sure you will really use the extras. Today the Philips AC1715 Air Purifier is the safest buy, and the Xiaomi Smart Air Purifier 4 Lite is the cheapest one we would still recommend.

Prices on Amazon.in move in a pattern. The deepest cuts land in the Great Indian Festival (around Navratri and Diwali), Prime Day in July and the Republic Day sale in January, usually with extra bank-card discounts and no-cost EMI. Judge a deal against the usual price we show, never against the MRP.

Order from Amazon itself or the brand's own storefront so the India warranty applies, keep the GST invoice and register the product with the brand straight away. For ACs, geysers, chimneys and purifiers, ask whether installation and the demo visit are free before you pay.

How we make the call: we read spec sheets, manuals and warranty terms, check how good the service network is in India and track the usual Amazon.in price. A product gets “Buy” only if we would tell a friend to buy it at that price. Brands cannot pay for a verdict.
