How to Choose the Ideal Air Purifier for Dealing with Air Pollution in India
PUBLISHED ON: 20-May-2025
Imagine stepping out of your home on a winter morning. Instead of fresh air, a thick layer of smog engulfs the surroundings, making breathing difficult. According to a 2023 report by the IQAir World Air Quality Index, 39 out of the world's 50 most polluted cities are in India.
With rising levels of PM2.5 and PM10 pollutants, indoor air quality is also deteriorating, leading to respiratory diseases, allergies, and long-term health risks.
The good news? A home air purifier plays a crucial role in safeguarding your family from indoor pollutants. With so many choices available, finding the right one can feel daunting. This comprehensive guide simplifies the process, helping you make an informed decision.
Why Do You Need an Air Purifier in India?
Rising Air Pollution Levels
According to the WHO, air pollution contributes to 7 million premature deaths annually worldwide. In India, major contributors include vehicle emissions, construction dust, industrial pollution, and household pollutants like cooking smoke.
Health Risks of Poor Air Quality
• Short-term effects: Eye irritation, coughing, headaches, and respiratory distress
• Long-term effects: Asthma, lung infections, cardiovascular diseases, and weakened immunity
• Vulnerable groups: Children, elderly individuals, pregnant women, and people with respiratory conditions
Indoor Air is More Polluted Than You Think
Many people assume that staying indoors protects them from pollution. However, indoor air can be 2-5 times more polluted than outdoor air due to cooking fumes, pet dander, mould spores, and household chemicals. This makes a home air purifier a necessity, not a luxury.
Key Features to Look for in the Best Air Purifiers
When selecting from the top air purifiers, consider these critical features:
Type of Filtration Technology
A high-quality air purifier should include multiple filtration stages to tackle various pollutants:
• Pre-filter – Traps larger particles such as dust and pet hair, preventing them from reaching the main filtration system.
• HEPA Filter (H13 or H14 True HEPA) – Traps 99.97% of fine particles like PM2.5, pollen, and mould
• Activated Carbon Filter – Removes harmful gases, volatile organic compounds (VOCs), and odours
The Forbes Smart 355 Surround 360° features a 4-stage filtration system, including a True H13 HEPA filter and activated carbon filter, making it highly effective for urban households.
Coverage Area & CADR (Clean Air Delivery Rate)
• Small rooms (up to 250 sq. ft.): CADR of 100-150 m³/hr
• Medium rooms (250-500 sq. ft.): CADR of 200-300 m³/hr
• Large rooms (above 500 sq. ft.): CADR of 350+ m³/hr
The Forbes Smart 500 Surround 360° is ideal for large spaces as it offers 360° air intake and a high CADR rate, ensuring rapid air purification in bigger rooms.
IoT and Smart Features
IoT-based air quality monitoring systems utilise sensors to detect harmful pollutants like CO2, VOCs, and PM2.5 in real time. These smart purifiers:
• Automatically adjust fan speeds based on pollution levels
• Connect to mobile apps for remote monitoring
• Provide real-time air quality updates
Both the Forbes Smart 355 and Forbes Smart 500 feature WiFi connectivity and sensors that adjust settings automatically to keep indoor air clean.
Noise Levels & Energy Efficiency
• Look for whisper-quiet operation below 35 dB (ideal for bedrooms)
• Energy-efficient models help cut electricity costs
Filter Replacement & Maintenance
• Check the cost and availability of filters before buying
• Models with filter change indicators are more convenient

- Replace HEPA and carbon filters as per manufacturer guidelines
- Check the sensor and app connectivity to ensure accurate air quality monitoring
Pro Tip: Some premium models like the Forbes Smart 500 have auto-filter change indicators, making maintenance hassle-free.
FAQs
Are air purifiers effective against PM2.5 pollution?
Yes, air purifiers by Forbes with True HEPA filters remove up to 99.97% of PM2.5 particles, significantly improving indoor air quality.
Can an air purifier eliminate cooking odours and smoke?
Yes, an activated carbon filter can absorb cooking smells, cigarette smoke, and VOCs from household cleaning products.
How can I check if my air purifier is functioning properly?
Many top air purifiers have real-time air quality indicators. If pollution levels drop and the air smells fresher, your purifier is doing its job.
Do air purifiers consume a lot of electricity?
Most modern home air purifiers are energy-efficient, consuming between 25W to 80W, like a ceiling fan.
Is a higher CADR always better?
Not necessarily. A CADR matched to your room size is more important than just opting for the highest rating.
Conclusion
With rising pollution levels in India, investing in a high-quality air purifier is essential for your well-being. Whether you're looking for an advanced IoT-enabled purifier or a simple yet effective home air purifier, choose one that suits your needs.
