Qubo 1000 air purifier (Q1000): ₹19,399 price, the real room size, filter cost, and who should buy it

Short answer: the Qubo Q1000 is a good-value living-room purifier at ₹19,399–₹19,990. Of everything we priced this morning, only three bedroom-sized machines (Qubo's Q400 and Q500 and the Xiaomi 4 Lite) cost less per unit of CADR. But the "1,000 sq ft" on the box is a slow-circulation number. For Delhi-grade smog, buy it for a room of about 450–550 sq ft, budget ₹4,990 for each filter, and don't pay ₹5,000 extra for the Ultra.

Prices were checked on Qubo's store and the Amazon listings at about 8:50 AM IST on 19 October 2026. Amazon links on this page are affiliate links (disclosed at the bottom); the Qubo store link is a plain link.

Qubo 1000 air purifier price today, and three listings to watch

Three traps on the listings:

• The ₹4,990 "Q1000". An Amazon listing titled "Qubo Q1000 Smart Air Purifier" showed ₹4,990 with an MRP of ₹6,490, exactly the price and MRP of the HPH05 replacement filter on Qubo's store, with "only 2 left in stock". Whatever it turns out to be, it isn't a ₹4,990 purifier. Read the item description and box photos before you order.
• The ₹25,990 listing. A second Amazon listing titled "Qubo Smart Air Purifier Q1000 by Hero" costs ₹25,990, with an MRP of ₹34,990, which is the Ultra's MRP. That's ₹6,591 more than the standard listing above.
• The Ultra itself. On Qubo's own comparison table, the Q1000 and the Q1000 Ultra have identical numbers: 600 m³/h CADR, 1,000 sq ft, 65W, 57 dB, 5-in-1 H13 filter, up to 9,000 hours of filter life, 8.3 kg, 1-year warranty and the same HPH05 filter. The Ultra's Amazon copy mentions two pre-filters and a numeric PM2.5 readout, but the standard Q1000's listing claims both too. On the published specs, the extra ₹5,000 buys you nothing you can measure.

The 1,000 sq ft claim, done properly

A purifier's real job is to push your room's air through the filter several times an hour. That rate is called air changes per hour (ACH), and it depends on two things: CADR (the clean air the machine delivers) and the volume of your room, which includes the ceiling height that coverage claims ignore.

The Q1000's CADR is 600 m³/h. Here's what that means at different room sizes:

Why 4.8? AHAM, the US appliance body behind the most widely used CADR test, sizes rooms with its "2/3 rule": smoke CADR (in cubic feet a minute) should be at least two-thirds of the room's floor area. That works out to about 4.8 air changes an hour with an 8 ft ceiling. Under that rule, 600 m³/h (about 353 cfm) suits a room of about 550 sq ft. Indian flats often have 9–10 ft ceilings, which brings it down to about 440 sq ft.

Two caveats, in fairness to Qubo. First, Qubo doesn't say which standard its 600 m³/h figure comes from, and AHAM's rule uses the smoke CADR, usually the lowest of a machine's figures. Second, a 1,000 sq ft claim isn't unusual. Brands often quote the area a purifier can clean once an hour, or under a lenient standard. You can see the gap on two rival listings:

• Philips AC3221/60: the same 520 m³/h is "1,453 sq ft (NRCC)" or "670 sq ft (GB/T)", depending on the standard.
• WINIX 5500-2: the title says "up to 1,065 ft² in 1 hr", but the listing's own bullet gives an AHAM-verified room size of 230 sq ft.

So the honest reading is this: the Q1000 can circulate a 1,000 sq ft hall, but on a 'severe' day it will clean it slowly. It's at its best in a 450–550 sq ft living room with the doors shut.

What it costs to run

• Filter: ₹4,990 for the HPH05 on Qubo's store (MRP ₹6,490). Qubo's page now says "up to 9,000 hours", which is about 25 months at 12 hours a day. When the Q1000 launched in November 2024, the TOI and The Hindu quoted 15,000 hours. The current page is the one to plan around. In practice, smog clogs filters long before the hour counter runs out. Food Pharmer suggests a change every 3–6 months in Delhi and 6–12 months in cleaner cities, so a Delhi home should budget ₹5,000–₹10,000 a year for filters.
• Electricity: 65W at full speed. At 12 hours a day that's about 23 units a month, or roughly ₹190 a month at ₹8 a unit. Most of the time you'll run it on auto or low, so expect less.
• Warranty: 1 year. Coway's Airmega AIM listing, for comparison, offers 5 years on the motor and 1 year on electrical parts.

What the creators found

We read the transcripts of three YouTube videos. One tests the Q1000 itself; two compare purifiers across the market.

Sarcastic Sindhi, "Best Air Purifier 2025 - Qubo Q1000!" (Hindi): he bought the Q1000 for a studio he describes as "around 1,000 sq ft plus". He picked it partly because it's a Hero Group brand rather than a Chinese one. In his smoke test he burned incense until the purifier's reading went past 500, ran it on high, and about 40 minutes later the reading was down to 30. He liked the app (scheduling, filter-life display, remote on/off), the QSensAI mode that switches on at one PM2.5 level and off at another (his example: on at 100, off at 20), Alexa control, a dark, quiet sleep mode, and no chemical smell. He expects a filter to last 10–12 months normally, or 4–6 months in smoky or very polluted areas. Note that his readings come from the purifier's own sensor, which the next creator warns about.

TechWiser (Pratik), "We Tried Air Purifiers From 2,000 to 50,000! *Delhi Pollution*": this video didn't test the Q1000. It listed the smaller Qubo Q200 (₹6,990, about 225 sq ft by their rule) among its under-₹10,000 picks for small rooms. Three points from it matter for anyone buying a Q1000. First, the PM2.5 number on a purifier's display is "highly inaccurate", so run it at full speed for an hour, then leave it on auto. Second, only buy True HEPA H13 or H14, and never wash a HEPA filter. Third, buy from brands that have sold purifiers and filters for 4–5 years, because they found one brand that stopped selling filters a year after launch, which turned the purifier into e-waste. Their rough sizing rule is CADR × 1.5, which gives the Q1000 about 900 sq ft. That's more generous than AHAM's rule because it applies the multiplier to m³/h, not cubic feet a minute.

Food Pharmer (Revant Himatsingka), "I reviewed all air purifiers in India (Rs. 8000 to 70,000)" (Hindi): his team ran smoke, AQI-reduction (incense, starting around 400, 30 minutes on max) and decibel tests. For bedrooms he picked the Xiaomi 4 Lite and the Philips AC0920. For living rooms he recommended the Qubo Q1000, with two qualifiers. It's sold as a 1,000 sq ft purifier, but he'd treat it as ideal for 600–700 sq ft, and it's "a little loud" on high, so use medium or low. His general rule: brands exaggerate, so assume a purifier works well in about two-thirds of the area it claims.

Put together, the three agree more than they differ. The Q1000 clears smoke quickly and is a sensible living-room machine. Nobody treats "1,000 sq ft" literally. Our maths (440–550 sq ft at 4.8 changes an hour) is the strictest of the four readings, Food Pharmer's 600–700 is the middle one, and TechWiser's ×1.5 rule (900 sq ft) is the most generous.

Qubo Q1000 vs rivals, on value per unit of clean air

Prices checked at about 8:50 AM IST, 19 Oct 2026. CADR and coverage claims are each brand's own figures. "Room at 4.8 ACH" uses the AHAM-style maths above.

What the table says:

• For a living room, the Q1000 is the value pick. Among the big-room machines, nothing gives you more CADR per rupee. The Honeywell moves more air but costs ₹5,600 more. The Philips adds temperature and humidity sensing and an exact PM2.5 readout, but costs about ₹10 more per unit of CADR.
• For a bedroom, don't buy a Q1000. A 150–250 sq ft bedroom needs roughly 160–340 m³/h at 4.8 changes an hour, depending on the ceiling. The Xiaomi 4 Lite (360 m³/h) or the Qubo Q500 (380 m³/h), both ₹10,990, covers that for about ₹8,400 less. The Q400 (₹8,990) is enough up to about 240 sq ft with a 10 ft ceiling.
• If you want longevity over app features, the Coway AIM's 5-year motor warranty is the strongest promise on this list, but it's a 355 sq ft machine.

Before you buy any purifier this week

• Measure the room, including the ceiling. Then run the numbers in the calculator above.
• Close the room. Every creator above makes the same point: an open door to a smoggy corridor defeats any purifier.
• Run it on high first. Run it at full speed for 30–60 minutes, then switch to auto. Don't trust the on-device PM2.5 number to tell you the room is clean.
• Price the filter before the machine. For the Q1000 that's ₹4,990 each time, and in Delhi you may need two or more a year.
• Rent if you're moving. If you might move within a year or two, see our air purifier on rent comparison for Delhi NCR.

My take

The Qubo Q1000 is the purifier I'd point most NCR families to for the main living area this winter, as long as they buy it for the right room. At ₹19,399 it gives more clean air per rupee than the Philips or Honeywell big-room models, it's from a Hero Group company that has sold purifiers and filters in India since at least 2023, and the one creator who tested it hard on video watched it clear incense smoke properly. What I don't like is the marketing. "1,000 sq ft" sets people up to put one unit in a hall, open to the kitchen and stairwell, and wonder why the air still feels heavy. The quiet change from 15,000 to 9,000 hours of filter life doesn't help either.

Buy it if: your living room is about 400–600 sq ft, you'll keep the doors closed, you want app control and scheduling, and you've set aside about ₹5,000 for each filter change. Get the standard Q1000 at the lower of the Amazon and Qubo-store prices on the day.

Skip it if: it's for a bedroom (buy a Q400, Q500 or Xiaomi 4 Lite and save ₹8,000–₹10,000), you need near-silent running at full speed, or your space is a true 1,000 sq ft open hall. For that, two smaller units placed apart will do better than one big one.

Don't buy: the Q1000 Ultra at ₹5,000 more, until Qubo publishes a spec that's actually different. Also skip any "Q1000" at a price that's too good to be true: ₹4,990 is what the filter costs.

I haven't used a Qubo purifier myself. This verdict is built on Qubo's published specs, the live Amazon and Qubo-store listings, AHAM's sizing method and the three creators credited above.
