Diwali celebrations may have lit up Delhi-NCR, but the days that followed brought a familiar problem: a sharp deterioration in air quality. Firecracker emissions added to the region’s existing pollution burden, while seasonal factors such as weak winds and falling temperatures made it harder for pollutants to disperse.
As PM2.5 levels become a growing concern, I believe indoor air quality deserves as much attention as outdoor AQI readings. Choosing an air purifier for home use, however, involves more than comparing filtration claims.
I would look closely at HEPA filtration, CADR, room coverage and replacement-filter costs before deciding. With the Amazon Great Indian Festival Sale bringing several options into focus, here are five air purifiers worth considering for homes across Delhi-NCR.

The Xiaomi Smart Air Purifier 4 Lite is designed to make indoor air quality easier to manage. Its three-layer filtration system targets dust, smoke and fine airborne particles, while the built-in AQI display lets you check pollution levels at a glance. I also like the convenience of app and voice controls, particularly when adjusting settings from across the room.
What are buyers saying on Amazon?
Buyers appreciate the purifier's air-quality monitoring, convenient app controls and compact design. Its filtration performance and relatively quiet operation also make it suitable for bedrooms and smaller living spaces. However, replacement-filter costs and individual experiences with noise levels are worth considering.
Why should you consider buying this air purifier?
I would consider this model if I wanted a smart air purifier for a bedroom or medium-sized living room. Its True HEPA filtration, 360 m³/h CADR and real-time AQI monitoring make it a practical option for Delhi-NCR homes.

I prefer appliances that do their job without demanding too much attention, and the Coway Airmega 150 fits that philosophy well. It features a three-stage filtration system comprising a pre-filter, a urethane carbon filter and a Green True HEPA filter to tackle dust, smoke and fine airborne particles. Its automatic mode adjusts the fan speed based on indoor air quality, while the 8,500-hour filter life reduces replacement frequency.
What are buyers saying on Amazon?
Buyers appreciate the Airmega 150's relatively quiet operation, particularly in Sleep mode, and its ability to improve indoor air quality. The automatic mode, straightforward controls and easy filter maintenance also receive positive feedback. However, some buyers have pointed out minor design shortcomings, including the absence of a cover over the top air outlet.
Why should you consider buying this air purifier?
I would consider the Coway Airmega 150 if I wanted a straightforward air purifier for a bedroom or medium-sized living room without relying on smartphone controls. Its 303 m³/h CADR, 355 sq. ft. coverage and long-lasting HEPA filter make it a practical option. The seven-year motor warranty is another consideration for buyers prioritising long-term ownership.

The Mijia Smart Air Purifier 6 stands out for its combination of high-capacity purification and detailed air-quality monitoring. Its five-stage PentaClean filtration system uses a primary filter, a high-efficiency filter, activated carbon, UV-C sterilisation and negative ion technology to tackle airborne pollutants, odours and allergens. I particularly like its five-sensor setup, which monitors PM1, PM2.5, dust, temperature and humidity, displaying the readings on its colour screen.
What are buyers saying on Amazon?
Buyers appreciate the Mijia Smart Air Purifier 6's air-quality monitoring, five-stage filtration system and convenient smart controls. Its ability to track PM1 and PM2.5 levels also makes it an interesting option for pollution-conscious households. However, feedback on fan noise at higher speeds and the recurring cost of replacement filters are worth considering. Individual experiences may vary.

I would consider this purifier for a large living room or open-plan space. Its 443 m³/h CADR, five-stage filtration and PM1 monitoring make it particularly suitable for households looking to manage indoor pollution.

The Philips AC3220/60 is built for households that need higher purification capacity without compromising too much on noise levels. It uses a dual-fan design and a three-layer filtration system comprising a pre-filter, a HEPA NanoProtect filter and an activated carbon filter to capture dust, smoke, allergens and fine airborne particles. I particularly like its 520 m³/h CADR, numerical PM2.5 monitoring and Air+ app support, which make it easier to monitor and manage indoor air quality.
What are buyers saying on Amazon?
Buyers appreciate the Philips AC3220/60's purification performance, quiet operation, real-time AQI monitoring and convenient app controls. Some find it effective at reducing PM2.5 levels in bedrooms and living rooms. However, feedback also points to limitations in its advertised room coverage and concerns about replacement-filter availability. Individual experiences may vary.
Why should you consider buying this air purifier?
I would consider the Philips AC3220/60 for a larger bedroom or living room where faster purification matters. Its 520 m³/h CADR, dual-fan design, detailed AQI display and app controls make it a capable choice for pollution-prone homes during the winter months.

I find the Dyson HushJet Compact interesting because it combines a relatively small footprint with a filtration system designed to tackle both particulate matter and household odours. Its star-shaped HushJet nozzle delivers concentrated airflow while reducing turbulence and noise. The electrostatic filter captures 99.97% of particles as small as 0.3 microns, while the activated carbon filter targets gases such as nitrogen dioxide. I also appreciate its five-year electrostatic filter life.
What are buyers saying on Amazon?
Buyers appreciate the Dyson HushJet Compact's quiet operation, effective air purification, compact design and convenient app controls. Some find it particularly suitable for bedrooms, noting that Sleep mode keeps noise levels low at night. However, feedback also points to noticeable noise at higher fan speeds, its relatively large footprint for a compact purifier and the recurring cost of replacing the activated carbon filter. Individual experiences may vary.
Why should you consider buying this air purifier?
I would consider the Dyson HushJet for a bedroom or living room where compact dimensions, quiet operation and smart controls matter. Its five-year electrostatic filter life is appealing, but I would factor in the annual carbon filter replacement cost and its one-ACH coverage rating before purchasing.
Factors to consider when purchasing an air purifier
If you are looking for the best air purifier for home in Delhi NCR, consider these factors before making a purchase:
- HEPA filtration: Choose a genuine HEPA air purifier for home use to capture fine particles, including PM2.5, smoke and dust.

- Room coverage: Match the purifier's coverage to your room size and check its air changes per hour (ACH).

- Running costs: Compare replacement-filter prices, availability, electricity consumption and maintenance before choosing the best air purifier for home in India.
