Xiaomi Mijia 6 vs Qubo Q600 compared on airflow, formaldehyde rating, sensors, noise, filters and price, using Amazon.in data checked on 13 Nov 2026.
Xiaomi Mijia 6 vs Qubo Q600 is a curious matchup because the two machines are almost the same where it counts. Their airflow differs by 7 m³/h (443 against 450), they are both aimed at big living rooms and both come with a phone app. Yet the Mijia costs ₹17,999 and the Qubo ₹14,990. The question is whether the ₹3,009 gap buys you anything you will notice.
We went through both Amazon.in listings on 13 Nov 2026 and checked prices for genuine filters. We have not tested the machines ourselves, and where a figure is not published we say so rather than fill the gap.

Sources: the Mijia Smart Air Purifier 6 listing and the Qubo Q600 listing. A note on the Q600's size: its Amazon.in dimension and weight fields read 22.5 x 22.5 x 30 cm and 300 g, identical to the small Q200, and 300 g is clearly wrong for a purifier of this class. We have left them out. Ask the seller for the real footprint before you buy.
CADR is the volume of clean air a purifier delivers per hour. The Mijia 6 is rated at 443 m³/h and the Q600 at 450 m³/h, a 1.6% difference that nobody could notice in a room.
Divide each by 5 to get the volume it can clean five times an hour, the rate most people want in a polluted city, then convert for a 10 ft ceiling:
Xiaomi's own low-end figure (312 sq ft) matches that calculation almost exactly, which is a good sign for how the company states its range. Qubo's "up to 600 sq ft" works out to about 2.6 air changes an hour. Both claims are fine for ordinary air, and for heavy winter smog (Delhi NCR in November) we would hold each of them to roughly 250 to 350 sq ft. If you need to refresh your memory on the sums, our CADR guide shows them.
Per rupee, the Q600 is clearly ahead: about ₹33 per m³/h against ₹41 for the Mijia 6.
A formaldehyde rating. Xiaomi publishes a formaldehyde CADR of 218 m³/h and says the purifier removes 98% of formaldehyde and VOCs. That is useful information, because very few purifiers in India publish a gas figure. Two cautions: carbon layers have limited capacity and fill up, so a purifier is a supplement to ventilation after painting or furniture delivery, not a replacement. And Qubo's absence of a number does not prove the Q600 does worse, it only means you cannot check.
Five sensors and a colour display. The Mijia reads PM1, PM2.5, dust and allergens, temperature and humidity, and shows them on a colour screen. The Q600 shows PM2.5 as a number on the unit. If you like looking at data, or want to see PM1 (ultra-fine particles from smoke and vehicle exhaust), the Mijia gives more.
A published sleep noise level. Xiaomi says 32 dB in sleep mode. Qubo does not publish a decibel figure for the Q600 on Amazon.in. Moving 450 m³/h generally takes more fan speed, so expect the Q600 to be audible when it runs hard.
A magnetic back panel. Xiaomi's listing highlights a magnetic door that makes the 12-month filter change easy.
UV-C light and negative ions. Treat these as extras, not reasons to buy. Particle cleaning depends on airflow and HEPA filtering, which are the same in both. Ion generators in particular are something some buyers prefer to avoid, and we did not find an ozone figure for the Mijia 6, so if that worries you, ask Xiaomi before you buy.
Price, by a clear margin. ₹14,990 against ₹17,999.
A public, reasonably priced genuine filter. Qubo lists the Q600 filter at ₹3,390, rated for 9,000 hours. At 12 hours a day that is about two years, though in smog you may want to change it sooner. Over three years, the Q600 comes to roughly ₹14,990 + ₹3,390 = ₹18,380 with one filter change. For the Mijia 6 we cannot give a figure, because we did not find a genuine filter price. That is the biggest unknown in the Xiaomi's favour or against it.
A five-layer filter that lists activated carbon, a nano-silver coating and True HEPA H13. On paper that matches the Mijia's stack. The Mijia lists UV-C and ions where Qubo lists extra pre-filtering and silver.
A number on the unit itself, not just in the app.
| Mijia 6 | Qubo Q600 | |
|---|---|---|
| Purifier | ₹17,999 | ₹14,990 |
| Genuine filter | Price not found, change every 12 months | ₹3,390 every ~2 years at 12 h/day |
| Electricity at 12 h/day, ₹8 a unit | Up to ₹115 a month (40 W) | Not calculable, power not published |
Qubo does not publish the Q600's wattage on the listing, so we cannot compare electricity. Ask the seller, or check the label on the unit.
The Mijia 6 shows 4.2 out of 5 from 1,014 ratings and the Q600 4.0 from 1,421. Both figures are pooled across a brand's linked variants (the Mijia number is shared with the 4 Compact and the Qubo number with the Q200), so they do not separate the two models. Both come with a 1-year warranty. Neither brand has the service record of Philips or Coway for air purifiers, so check how a claim works in your city before you buy.

Look at something else if you need low running cost and strong reviews. The Coway Airmega 150 has a 4.7 rating from 6,824 buyers and a ₹3,299 filter, though it covers a smaller room. For more options see our best air purifier under ₹15,000 and our Xiaomi range guide. The Q600 also appears against the Philips in our Qubo Q600 vs Philips AC1715 comparison.
Prices checked on Amazon.in on 13 Nov 2026 and can change. Ratings (4.2 and 4.0) are pooled across linked variants.
The two cost within ₹3,009 of each other and move almost exactly the same air. For most homes we would take the Q600, and keep the Mijia 6 for homes where gases matter.
450 m³/h for ₹14,990, a genuine filter at a known ₹3,390, activated carbon and an on-unit PM2.5 number. It gives the same airflow as the Mijia 6 for 17% less.

It has more features: a published formaldehyde CADR (218 m³/h), five sensors, a colour display, UV-C and a published 32 dB sleep level. The Q600 moves the same air (450 m³/h against 443 m³/h) for ₹3,009 less (₹14,990 against ₹17,999 on 13 Nov 2026) and has a published genuine filter price. The Q600 is better value; the Mijia 6 is the more complete machine.
The Q600's genuine filter is listed at ₹3,390 for 9,000 hours. We could not find a genuine filter price for the Mijia 6, so its running cost is unknown. Xiaomi says the filter should be changed every 12 months. The Mijia 6 draws up to 40 W, about ₹115 a month at 12 hours a day; Qubo does not publish the Q600's power.
Both give about five air changes an hour in a room of 310 to 320 sq ft with a 10 ft ceiling. Xiaomi quotes 312 to 538 sq ft and Qubo says up to 600 sq ft, but both are best-case claims. In heavy smog, aim for 250 to 350 sq ft.
Xiaomi publishes a formaldehyde CADR of 218 m³/h and says the purifier removes 98% of formaldehyde and VOCs. Carbon filters have limited capacity, so for fresh paint or new furniture ventilate the room as well. Qubo does not publish a formaldehyde figure for the Q600.
Xiaomi lists 32 dB in sleep mode. Qubo does not publish a decibel figure for the Q600 on Amazon.in, so we cannot confirm which is quieter, though a fan that moves 450 m³/h will be audible at full speed.
Not in the way airflow and HEPA filtering do. UV-C and ionisers are extras. Particle cleaning is driven by CADR and the HEPA filter, which are almost equal here. Do not pay extra for them alone.
Little. The Mijia 6 shows 4.2 out of 5 from 1,014 ratings, shared with the Mijia 4 Compact, and the Q600 shows 4.0 from 1,421, shared with the Q200. Both are pooled across variants.
Yes. The Mijia 6 uses the Xiaomi Home app and the Q600 uses the Qubo app. Both support Alexa and Google Assistant, and both list a 1-year warranty.
