Coway's own HEPA filter costs ₹3,299 on Amazon.in, and Coway rates it for 8,500 hours, about 1.5 to 2 years. On Amazon.in, 6,816 buyers rate the purifier 4.7, the highest score here.
We compared seven models on maker specs and owner ratings, then sized each to a room and costed a year's use.

Best air purifiers in India: quick comparison
Sorted by price, with room sizes by AHAM's 2/3 rule.
| Air purifier | Price | CADR | Room size (2/3 rule) | Filter type | Filter price and life | Rating (reviews) |
|---|---|---|---|---|---|---|
| ~₹5,149 | 152 m³/h (89 cfm) | ~135 sq ft | H13 HEPA + carbon | ₹1,549*, 9,000 hrs or 1 yr | 4.0 (11,956) | |
| ~₹9,499 | 250 m³/h (147 cfm) | ~220 sq ft | HEPA NanoProtect, no carbon | ₹2,150, 1 yr or 9,000 hrs | 4.3 (702) | |
| ~₹9,799 | 240 m³/h (141 cfm) | ~210 sq ft | H13 HEPA + carbon | ₹2,999, 6 to 8 months | 4.4 (91,056) | |

| ~₹14,999 | 260 m³/h (153 cfm)† | ~230 sq ft | H13 HEPA + carbon | ₹3,299, 8,500 hrs | 4.7 (6,816) | |
| ~₹17,099 | 420 m³/h (247 cfm) | ~370 sq ft | HEPA NanoProtect + carbon | ₹4,900*, up to 3 yrs | 4.6 (671) | |

*No genuine filter on Amazon.in on 9 November, so the price is from the maker's own store. †Coway's CADR is from its US site for the Airmega 150, as the Indian listing gives none. That site rates the HEPA filter for one year, against 8,500 hours in India.
What size air purifier do you need for your room?
Choose a purifier whose CADR, in cfm, is at least two-thirds of your room's floor area in square feet. This 2/3 rule comes from AHAM, the US appliance makers' body that certifies CADR. A 150 sq ft bedroom needs 100 cfm or more, about 170 m³/h.
Indian listings give CADR in m³/h, so divide by 1.699 to get cfm (1 cfm = 1.699 m³/h), then multiply by 1.5 for the largest room in sq ft.
| Room size | CADR you need | Picks that cover it |
|---|---|---|
| 100 sq ft (small bedroom or study) | 67 cfm (113 m³/h) | All seven |
| 150 to 200 sq ft (bedroom) | 100 to 133 cfm (170 to 227 m³/h) | All except the Honeywell V1 |
| 200 to 250 sq ft (large bedroom) | 133 to 167 cfm (227 to 283 m³/h) | Xiaomi 4 Lite, Philips AC2220, Philips AC4221 (the Coway covers up to about 230 sq ft, the Philips AC0920 220 and the Levoit 210) |
| 250 to 300 sq ft (living room) | 167 to 200 cfm (283 to 340 m³/h) | Xiaomi 4 Lite, Philips AC2220, Philips AC4221 |
| 350 sq ft (large living room) | 233 cfm (396 m³/h) | Philips AC2220, Philips AC4221 |
| 400 to 500 sq ft (hall or open plan) | 267 to 333 cfm (453 to 566 m³/h) | Philips AC4221 |
- High ceilings need more. AHAM's rule assumes an 8-foot ceiling. With a 10-foot ceiling, each purifier covers about a fifth less floor area.
- CADR is not always measured the same way. Xiaomi and the Philips AC2220 quote CADR to China's GB/T 18801 standard, and the other Philips listings give GB/T room sizes, so treat their room sizes as a close guide.
How much does an air purifier cost to run per year?
About ₹2,000 to ₹8,000 a year for these seven, run 12 hours a day at full speed. Filters are most of it. The Honeywell V1 costs least, about ₹1,969, and the Levoit Core 300 most, about ₹7,960.
We divided each filter's price by the maker's filter life, taking the shorter end of any range and counting 12 hours of use a day. For Coway we used 1.5 years, the short end of its filter listing's 1.5 to 2 years, which is shorter than 8,500 hours at 12 hours a day.
For power, we used each maker's top wattage for 12 hours a day, at an assumed ₹8 a unit. On auto mode, most purifiers use less.
| Air purifier | Filter price | Maker's filter life | Filters a year | Top wattage | Power a year | Total a year |
|---|---|---|---|---|---|---|
| Honeywell Air Touch V1 | ₹1,549* | 9,000 hrs or 1 yr | ₹1,549 | 12 W | ₹420 | ₹1,969 |
| Philips AC2220 | ₹4,900* | Up to 3 yrs | ₹1,633 | 28 W | ₹981 | ₹2,614 |
| Philips AC0920 | ₹2,150 | 1 yr or 9,000 hrs | ₹2,150 | 21 W | ₹736 | ₹2,886 |
| Coway Airmega 150 | ₹3,299 | 8,500 hrs (1.5 to 2 yrs) | ₹2,199 | 38 W | ₹1,332 | ₹3,531 |
| Philips AC4221 | ₹3,999 | 1 yr | ₹3,999 | 54 W | ₹1,892 | ₹5,891 |
| Xiaomi 4 Lite | ₹2,999* | 6 to 12 months | ₹5,998 | 33 W | ₹1,156 | ₹7,154 |
| Levoit Core 300 | ₹2,999 | 6 to 8 months | ₹5,998 | 56 W | ₹1,962 | ₹7,960 |
- Genuine filters are hard to find for three picks. Amazon.in had no genuine filter for the Honeywell V1, Xiaomi 4 Lite or Philips AC2220 on 9 November, so we used the makers' store prices. Honeywell's and Philips' stores showed theirs out of stock.
- Filters for Philips air purifiers carry an FY code, such as FY0900/30 for the AC0920 and FY4200/30 for the AC4221.
- Longer life cuts the bill. If Xiaomi's filter lasts 12 months and Levoit's 8, they cost ₹2,999 and about ₹4,499 a year.
Best air purifier for home overall: Coway Airmega 150
Coway Airmega 150
H13 HEPA for rooms up to ~230 sq ft, an 8,500-hour filter and the best rating here.
~₹14,999Amazon.in
Check price →Around ₹14,999, rated 4.7 by 6,816 buyers, the best-rated air purifier here.
It pairs a pre-filter and a urethane carbon filter with an H13 HEPA filter. Coway's US site gives a CADR of 153 cfm, about 260 m³/h, enough for about 230 sq ft.
The filter is easy to get. Coway rates it for 8,500 hours, about 1.5 to 2 years, and it was in stock on Amazon.in at ₹3,299, sold by Coway's India distributor. That price is for the HEPA filter only.
Coway India doesn't say whether the carbon filter needs replacing separately, and Coway's US site says every 6 months. Add about ₹1,332 of power a year at the 38 W that Coway India lists.
In auto mode an air-quality sensor sets the fan speed, and Coway lists 22 to 49 dB. The motor warranty is 5 years, or 7 if you register. The listing mentions no app.
- Buy it if you want one well-rated purifier for a bedroom or small living room.
- Worth knowing: the HEPA filter is rated for one year on Coway's US site, not 8,500 hours. At one filter a year, it would cost about ₹4,631 a year to run.
Best air purifier for a bedroom: Philips AC0920
Philips AC0920
250 m³/h for bedrooms up to ~220 sq ft, a 20.5 dB sleep mode and a ₹2,150 yearly filter.
~₹9,499Amazon.in
Check price →Around ₹9,499, rated 4.3 by 702 buyers.
Philips quotes a CADR of 250 m³/h, about 147 cfm, which suits a bedroom of up to about 220 sq ft. The listing's 700 sq ft claim uses a different sizing method (NRCC), and the same listing gives 320 sq ft by China's GB/T standard.
It uses a pre-filter and a HEPA NanoProtect filter, with no carbon layer for smells, and Philips gives no HEPA grade. The FY0900/30 filter costs ₹2,150 on Amazon.in, and Philips rates it for one year or 9,000 hours.
It draws 21 W, and Philips lists 20.5 dB in sleep mode. Its sensor shows air quality, and the listing mentions no app.
- Buy it if you want a quiet bedroom purifier.
- Skip it if you need odour control.
Best air purifier for a large room: Philips AC2220
Philips AC2220
420 m³/h for living rooms up to ~370 sq ft, with a filter Philips rates for up to 3 years.
~₹17,099Amazon.in
Check price →Around ₹17,099, rated 4.6 by 671 buyers.
Philips quotes a CADR of 420 m³/h, about 247 cfm, enough for a living room of up to about 370 sq ft.
The pre-filter, HEPA NanoProtect and active carbon come as one FY2200/30 filter, which Philips says lasts up to three years, the longest here. Philips gives no HEPA grade. Philips' store lists it at ₹4,900, about ₹1,633 a year, but it was out of stock and not on Amazon.in.
Philips lists 13 to 45 dB and 28 W. It has Philips' AeraSense air-quality sensor and works with the Air+ app.
- Buy it if you are cleaning a living room of 300 to 370 sq ft.
- Worth knowing: the listing's model field says AC2210/10 while its title says AC2220, so check the model number on the box when it arrives.
Best budget air purifier for a small room: Honeywell Air Touch V1
Honeywell Air Touch V1
H13 HEPA and carbon for rooms up to ~135 sq ft, at about ₹1,969 a year to run.
~₹5,149Amazon.in
Check price →Around ₹5,149, rated 4.0 by 11,956 buyers. The count was 1,809 in September, so the listing may now pool ratings from other models.
It is the most affordable air purifier here with H13 HEPA and carbon. Honeywell quotes a CADR of 152 m³/h, about 89 cfm, which suits a small room of up to about 135 sq ft. Its listing bases the 235 sq ft claim on filtering all the room's air twice an hour.
Honeywell rates the filter for 9,000 hours or a year and the purifier at 12 W, so it costs about ₹1,969 a year to run, the least here. Its ₹1,549 filter, though, was sold out on Honeywell's store and not on Amazon.in.
Honeywell lists 29 dB, three speeds and a filter light, but no air-quality sensor or app.
- Buy it if your budget is about ₹5,000 and the room is small.
- Skip it if the room is bigger than about 135 sq ft.
Best air purifier for allergies and pets: Levoit Core 300
Levoit Core 300
H13 HEPA, 240 m³/h for ~210 sq ft and a pet-allergy filter option. 91,056 ratings.
~₹9,799Amazon.in
Check price →Around ₹9,799, rated 4.4 by 91,056 buyers.
Levoit quotes a CADR of 141 cfm, or 240 m³/h, enough for about 210 sq ft. Its filter combines a pre-filter, H13 HEPA and activated carbon, and Levoit also sells Pet Allergy and Smoke Remover versions.
A purifier does not treat an allergy, so keep following your doctor's advice.
Running cost is the trade-off. The Core 300-RF filter costs ₹2,999 on Amazon.in, and Levoit says to replace it every 6 to 8 months. With power at 56 W, the total is about ₹7,960 a year. Levoit lists 24 dB in sleep mode and no sensor or app.
- Buy it if you have pets or dust allergies at home.
- Skip it if filter cost matters most.
Best value HEPA room air purifier with an app: Xiaomi Smart Air Purifier 4 Lite
Xiaomi Smart Air Purifier 4 Lite
360 m³/h for ~320 sq ft and app control, but a ₹2,999 filter every 6 to 12 months.
~₹10,990Amazon.in
Check price →Around ₹10,990, rated 4.2 by 1,007 buyers, but the same count appears on Xiaomi's 4 Compact and Purifier 6 listings, so the ratings may cover all three models.
It gives the most clean air per rupee here. Xiaomi quotes a CADR of 360 m³/h, about 212 cfm, enough for about 320 sq ft. That is 33 m³/h per ₹1,000, against 17 for the Coway.
The filter combines a primary filter, Xiaomi's HEPA layer and activated carbon, but unlike the H13 picks, Xiaomi gives no HEPA grade. Xiaomi's store lists it at ₹2,999 and says to replace it every 6 to 12 months.
A laser sensor shows PM2.5, and it works with an app, Alexa and Google Assistant. Xiaomi lists 33 W and 33.4 dB in night mode.
- Buy it if you want app control for a living room for under ₹11,000.
- Skip it if running cost matters most: about ₹7,154 a year.
Best premium air purifier for a big living room: Philips AC4221
Philips AC4221
600 m³/h for halls up to ~530 sq ft, with four sensors and the Air+ app.
~₹24,232Amazon.in
Check price →Around ₹24,232, rated 4.6 by 196 buyers.
Philips quotes a CADR of 600 m³/h, about 353 cfm, the most here, enough for a hall of up to about 530 sq ft. A pre-filter, HEPA NanoProtect and two carbon layers make up its four-layer filter, and Philips gives no HEPA grade.
The FY4200/30 set of two filters costs ₹3,999 on Amazon.in, and Philips India says to change it yearly. With power at 54 W, the total is about ₹5,891 a year.
It has PM2.5, gas, temperature and humidity sensors and works with the Air+ app. Philips lists 15 to 51.5 dB.
- Buy it if you need one purifier for a room of 400 to 530 sq ft.
- Skip it if the room is under 300 sq ft.
Best air purifier for Delhi smog: AQI levels and PM2.5
India's AQI runs to 500, and above 200 is Poor or worse. In a Delhi winter, close one room and size the purifier to it: the Coway Airmega 150 for a bedroom of up to about 230 sq ft, or the Philips AC2220 for a living room of up to about 370 sq ft.
The Central Pollution Control Board (CPCB) rates 0 to 50 Good, 51 to 100 Satisfactory, 101 to 200 Moderate, 201 to 300 Poor, 301 to 400 Very Poor and 401 to 500 Severe.
For PM2.5, the scale turns Poor above 90 µg/m³ over 24 hours, as the government's AQI notice sets out, and Severe above 250, according to India's National Air Quality Index.
- Close the room first. Shut the windows and door and run the purifier on high first, then switch to auto, or to a lower speed on the Honeywell V1 and Levoit Core 300, which list no air-quality sensor.
- Plan for power cuts. These picks draw 12 to 56 W, so a home inverter can run one. Our best inverter for home guide explains backup sizing.
What about AGARO, Winix, Qubo and other brands?
We left these out after checking them on Amazon.in on 9 November.
- The AGARO Imperial air purifier, around ₹10,669 with a 240 m³/h CADR, is rated 2.7 by 452 buyers.
- The Winix 5500-2, around ₹15,998, has bullet points describing Winix's smaller 60 cfm Mini 360, so the model you get is unclear.
- The Qubo Q200, around ₹7,490 and rated 4.1 by 1,410 buyers, has an app and a 150 m³/h CADR, but costs about ₹2,340 more than the Honeywell V1.
- The Coway Airmega 50, around ₹6,999 and rated 4.4 by 321 buyers, had only a ₹6,347 filter from a third-party seller on Amazon.in.
- Xiaomi's Purifier 6 lists an ion generator and a UV-C lamp. Skip purifiers that lead with ionisers or UV.
- The Shark HP300, around ₹28,999, has what Shark calls a five-year filter, though Shark says its anti-odour part needs replacing every 3 months, and Shark India doesn't publish a CADR.
What to check before you buy an air purifier
- CADR and room size. Divide m³/h by 1.7 for cfm. The cfm should be at least two-thirds of your floor area in sq ft. With a 10-foot ceiling, each purifier covers a fifth less floor area.
- Filter type. Look for H13 HEPA, or a filter the maker calls HEPA, plus carbon for smells. "HEPA-type" is not HEPA.
- Filter cost and life. Check the original filter's price, life and stock before you buy. For these picks, filters cost ₹1,549 to ₹5,998 a year.
- Price. These picks cost from around ₹5,149 to ₹24,232. Compare the selling price, not the MRP.
- Noise, sensor and app. For a bedroom, look for a sleep mode of 25 dB or less. A PM2.5 sensor makes auto mode useful.
Which air purifier should you buy?
For most homes, buy the Coway Airmega 150 at around ₹14,999. For a bedroom, buy the Philips AC0920 at around ₹9,499, and for a living room, the Philips AC2220 at around ₹17,099. Under ₹6,000, buy the Honeywell Air Touch V1.
