The recent rain may have briefly scrubbed Delhi NCR's air, dropping the AQI to a breathable 133 yesterday, but don't pack away your air purifier just yet. The Ministry of Earth Sciences forecasts a quick return to "poor" and "very poor" air quality over the next few days. If you're looking to buy or upgrade, we've shortlisted six air purifiers across different budgets and room sizes. When choosing, the most critical spec to watch is the Clean Air Delivery Rate (CADR). A machine with an impressive HEPA filter won't help much if it lacks the fan power to actually circulate and clean the air in your specific space. Read on for our full comparison, including real-world CADR performance, pros, cons and customer reviews to help you find the right match for your home.

Loading Suggestions...

The Qubo Q200 is a compact purifier designed for bedrooms and smaller rooms rather than large living spaces. Its listed configuration includes a five-stage filtration system, True HEPA H13 filter, activated carbon layer and app control. With a claimed CADR of 150m³/h and coverage of up to 200 sq. ft., it is better suited to a personal room than an open-plan home.

Factors to consider when buying an air purifier

• CADR and room size: CADR tells you how much filtered air a purifier delivers. Match it to the room where you will use the machine. A compact purifier may work well in a bedroom but struggle to keep up in a large living room.
• Filter type and replacement cost: Look for a HEPA filter for fine particles and an activated carbon layer for certain gases and odours. Check the replacement-filter price and availability before buying, since the initial discount is only part of the cost.
• Noise and power consumption: If the purifier will run overnight, check its Sleep Mode noise rating. Power consumption also matters when you plan to operate it for several hours every day.
• Air quality monitoring and automatic mode: A PM2.5 sensor or air quality indicator helps you understand indoor conditions. Auto Mode can adjust fan speed, but check whether the purifier's display and controls are easy to read and use.

FAQs

Do air purifiers help with Delhi-NCR pollution?

Air purifiers with suitable particle filtration can reduce airborne particulate matter indoors. Their effectiveness depends on the purifier's CADR, room size, filter condition and how the room is used.

What CADR should I look for in an air purifier?

Choose a CADR suited to the size of your room and how frequently you want its air cleaned. Larger rooms generally need a purifier with a higher CADR.

Is a HEPA filter important for an air purifier?

Yes. A suitable HEPA filter can capture fine airborne particles, including dust and pollen. Check the filter's specification and the manufacturer's stated particle-filtration performance.

Should I keep an air purifier running throughout the day?

It can be useful to run a purifier for extended periods during high-pollution conditions, provided you follow the manufacturer's operating instructions. Keep up with filter maintenance and choose a fan setting appropriate for the room.

How often should an air purifier filter be replaced?

It depends on the model, filter type and usage. Follow the manufacturer's replacement schedule and check the filter indicator where available. High-pollution conditions and frequent use may mean the filter needs attention sooner.
