Xiaomi air purifier models in India: the Mijia 4 Compact, Xiaomi 4 Lite and Mijia Purifier 6 compared by CADR, real room size, price and filter cost, checked on 11 Nov 2026.
Xiaomi sells air purifiers in India under two names: the older Xiaomi branding (Smart Air Purifier 4 Lite) and the newer Mijia by Xiaomi line launched in August 2026 (Air Purifier 4 Compact and Smart Air Purifier 6). That naming alone confuses buyers, and the headline coverage figures on the listings are generous. This guide sorts out the current models, what each is really suited to, filter costs and which one to pick. Prices and ratings were checked on Amazon.in on 11 Nov 2026, and launch details come from coverage of Xiaomi India's announcement.
| Model | Amazon.in price (11 Nov 2026) | Rating | CADR | Best for |
|---|---|---|---|---|
| Mijia Air Purifier 4 Compact | ₹6,990 | 4.2 | 230 m³/h | Bedroom, nursery, study |
| Xiaomi Smart Air Purifier 4 Lite | ₹10,990 | 4.2 | 360 m³/h (listing) | Bedroom or small living room |
| Mijia Smart Air Purifier 6 | ₹17,999 | 4.2 | 443 m³/h (particles), 218 m³/h (formaldehyde) | Large rooms, gas-sensitive homes |
Launch prices were ₹7,999 for the 4 Compact, ₹12,999 for the 4 Lite and ₹19,999 for the Purifier 6, with sales from 2 September 2026 on mi.com, Amazon, Flipkart, Blinkit and Xiaomi stores. Sources: Digit and MySmartPrice.
Mijia is Xiaomi's smart-home product brand. In India two of the three purifiers carry the Mijia name and the 4 Lite keeps Xiaomi's. All three use the Xiaomi Home app, which handles schedules, timers, filter checks and remote control. We found no practical difference in support between the two names, but check that the seller on Amazon.in is the official store.
The listing for the Mijia 4 Compact says "covers 400 sq ft", yet its own bullet states that it purifies spaces of 172 to 291 sq ft, or up to 517 sq ft on a 2-air-change-per-hour basis. The 4 Lite listing shows both 462 and 640 sq ft in different places. The Purifier 6 is billed as covering up to 940 sq ft on two air changes per hour.
For real winter smog, we advise:
A small, light (2.2 kg) purifier with a three-in-one filter and a PM2.5 sensor. It claims TÜV Rheinland Allergy Care certification, a particle CADR of 230 m³/h and 20 dB in sleep mode with the display off. It draws up to 27 W. The Xiaomi Home app, Alexa and Google Assistant are supported. It is the cheapest app-connected purifier from a major brand we can recommend for a small room.
The best-known Xiaomi purifier in India. Three layers: primary filter, high-efficiency filter and activated carbon. CADR is 360 m³/h on the listing, and noise in night mode is about 33 dB. It also carries TÜV Rheinland Allergy Care certification. Compatible third-party filters are about ₹2,400 to ₹3,000 on Amazon.in. We did not find an official replacement filter price on Xiaomi's pages, so check at purchase.
The top model. Particle CADR is 443 m³/h and formaldehyde CADR 218 m³/h, with five stages: primary, high-efficiency, activated carbon, UV-C sterilisation and negative ions. It shows PM2.5, PM1, temperature and humidity on a colour display, runs at about 32 dB in sleep mode, and supports Alexa and Google Assistant. UV-C and ionisers add features but not necessarily cleaner air, so do not pay extra for them alone. Because the formaldehyde CADR is published, it suits homes with new paint or furniture.
| Model | Replacement filter |
|---|---|
| Xiaomi 4 Lite | Third-party HEPA/carbon filters listed at about ₹2,399 to ₹2,999 on Amazon.in; official price not found |
| Mijia 4 Compact | Not published on the pages we checked |
| Mijia Purifier 6 | Not published on the pages we checked |
Xiaomi's launch coverage did not give replacement filter prices. This is the biggest gap in the Xiaomi range compared with Coway (₹3,299 genuine) and Philips (₹2,720 to ₹4,995). Before buying, message the Amazon seller or Xiaomi support for the genuine price and availability. Third-party filters are cheaper but unverified, and a poorly fitted filter lets air bypass the HEPA layer. Our Xiaomi purifier problems guide covers common faults and fixes.
