Air quality inside most Indian homes swings wildly through the day, from cooking fumes in the kitchen to dust drifting in through open windows. Xiaomi wants a device in every room that keeps track of it.
The company has picked air purifiers to introduce Mijia by Xiaomi, its global smart home and lifestyle brand, in the Indian market. Two new models arrive under this label, the Mijia Smart Air Purifier 6 and the Mijia Smart Air Purifier 4 Compact.
Alongside them, the well-known Xiaomi Smart Air Purifier 4 Lite makes a comeback. The three devices are built for different room sizes, from compact study corners to large living rooms, and all three go on sale on September 2, 2026.

What Is Mijia by Xiaomi
Mijia is Xiaomi’s dedicated smart home sub-brand, already established internationally. Its Indian debut signals that the company wants a separate identity for connected home appliances rather than folding them under the main Xiaomi label.
Sandeep Singh Arora, Chief Business Officer at Xiaomi India, said the launch reflects the company’s focus on addressing everyday consumer needs through products built around smart monitoring, connected control and quiet operation.
Air purifiers are the first category to carry the new branding in the country, with more product lines expected to join the portfolio over time.
Mijia Smart Air Purifier 6: Built for Bigger Rooms
The Mijia Smart Air Purifier 6 targets larger living spaces, rated to cover up to 940 sq ft based on two air changes per hour. This metric essentially tells you how many times the device can fully cycle the air in a room within an hour.
That makes it a fit for spacious living rooms, master bedrooms or open-plan layouts common in bigger Indian apartments. Performance numbers back up the room coverage claim.
The purifier carries a Particle CADR of 443 m³/h and a Formaldehyde CADR of 218 m³/h. CADR is short for Clean Air Delivery Rate, essentially how much purified air the unit pushes out every hour.
Xiaomi says it can fully refresh a 108 sq ft room in roughly 3.5 minutes under test conditions.
| Specification | Mijia Smart Air Purifier 6 |
|---|---|
| Room coverage | Up to 940 sq ft (2 ACPH) |
| Particle CADR | 443 m³/h |
| Formaldehyde CADR | 218 m³/h |
| Filtration | 5-stage PentaClean system with activated carbon, UV-C and negative ions |
| Sleep Mode noise | Approximately 32dB(A) |
| Display | Large colour screen with PM2.5, PM1, temperature and humidity |
| App and voice control | Xiaomi Home App, Amazon Alexa, Google Assistant |
| Price | Rs 19,999 |
The standout feature here is what Xiaomi calls India’s only PentaClean purification system, a five-stage setup that combines standard filtration with activated carbon for gaseous pollutants.
Additional treatment layers come from UV-C light and negative ion technology. The built-in colour display shows live PM2.5 and PM1 readings, temperature and humidity.
That gives households a running picture of indoor air quality rather than a black box that just hums in the corner. For nighttime use, a dedicated Sleep Mode keeps operating noise around 32dB(A).
That is quiet enough to run through the night in a bedroom without becoming a distraction. The purifier connects through the Xiaomi Home App for scheduling, monitoring and filter tracking.
It also works with Amazon Alexa and Google Assistant for voice commands, depending on regional availability. Those weighing this against other options can check current listings on Amazon once the sale opens.
Mijia Smart Air Purifier 4 Compact: Made for Personal Spaces
Not every room needs a large-format purifier, and that is where the Mijia Smart Air Purifier 4 Compact fits in. Designed for rooms of 400+ sq ft, it targets bedrooms, kids’ rooms, study corners and home offices.
Despite the compact size, it runs a 3-in-1 filtration system rated to capture 99.97% of particles as small as 0.3 microns. That covers the kind of fine particulate matter that includes dust, smoke and pollen.
It also carries TÜV Rheinland Allergy Care Certification, an independent test standard that verifies a device’s ability to filter common airborne allergens such as pollen and dust.
| Specification | Mijia Smart Air Purifier 4 Compact |
|---|---|
| Room coverage | 400+ sq ft |
| Filtration | 3-in-1 system, 99.97% capture at 0.3 microns |
| Certification | TÜV Rheinland Allergy Care |
| Weight | 2.2kg |
| Sleep Mode noise | 20dB |
| Power draw | Approximately 0.65kWh over 24 hours at max power |
| Price | Rs 7,999 |
Understanding air quality at a glance is handled through a four-colour indicator, where green signals good air and the scale moves through yellow, orange and red as pollution levels climb.
Three operating modes cover different needs. Auto Mode adjusts purification speed based on detected air quality, Sleep Mode trims noise down to just 20dB with the display switched off, and Manual Mode hands full control back to the user.
At 2.2kg, the unit is light enough to move between a desk, side table or floor. Xiaomi pegs its electricity draw at roughly 0.65kWh for 24 hours of continuous use at maximum power.
That keeps running costs manageable for a device meant to stay on for long stretches. It links up with the Xiaomi Home App for remote control and also answers to Amazon Alexa and Google Assistant voice commands.

Xiaomi Smart Air Purifier 4 Lite Makes a Comeback
Alongside the two Mijia launches, Xiaomi is reintroducing the Xiaomi Smart Air Purifier 4 Lite. It already has a following among buyers searching for a mid-range purifier that does not compromise on core features.
It offers up to 360 m³/h Particle CADR and covers 269 to 463 sq ft, positioning it between the Compact and the Air Purifier 6 in terms of room size.
Its three-layer filtration system pairs a primary filter with a high-efficiency filter and activated carbon to handle both particulate matter and household odours.
It carries the same TÜV Rheinland Allergy Care Certification as the Compact model. A 33.4dB(A) Night Mode, live air-quality monitoring and Xiaomi Home App connectivity round out the package.
