In recent years, the air quality in many Indian cities has declined to alarming levels. According to the 2024 World Air Quality Report, 84 of the world’s 100 most polluted cities are in India. It has also been proven that prolonged exposure to polluted air is linked to respiratory illnesses, cardiovascular problems, and a weakened immune system.
As more and more pollutants and allergens find their way into our homes, air purifiers are becoming more of a necessity than a luxury. The market is filled with a wide range of air purifiers, each with its own unique set of features that make picking one a complicated process. However, we’ve put together a small guide to help you choose the right kind of air purifier for your home.
Why use an air purifier?
It’s not just the air quality in your city that can necessitate the use of an air purifier. If your home is near a construction site, a particularly dusty area, an area with a lot of green coverage, or even a highly damp area with poor ventilation, it can lead to an increase in allergies and respiratory issues such as asthma. Here’s why you should consider using an air purifier:
- Air purifiers can trap allergens like pollen, dust mites, pet dander, and mould spores, which are known to trigger allergic reactions and asthma attacks.
- They can capture particulate matter (PM2.5 and PM10), volatile organic compounds, and even harmful gases like formaldehyde and nitrogen dioxide, which are commonly found in urban homes.
- Cleaner air promotes better sleep, reduces fatigue, and boosts overall immunity.
It’s important to keep in mind that using a substandard or poorly maintained air purifier can be counterproductive. Ineffective filters may release trapped pollutants back into the air or create ozone, which can worsen respiratory issues. That’s why investing in a certified and high-quality product is crucial.
Factors to Consider Before Buying an Air Purifier

1. Filtration system: The most important feature of any air purifier is its filtration system. Look for the True HEPA Filters, which capture 99.97% of particles as small as 0.3 microns or the activated carbon filters, which are excellent for absorbing odours, smoke, and harmful gases. Some premium models may also include antibacterial layers or UV filters for microbial protection.
2. Clean Air Delivery Rate (CADR): CADR indicates how quickly and efficiently a purifier can clean the air in a given square footage. A higher CADR rating means faster purification. It’s essential to match the CADR to the size of your room for maximum efficiency.
3. Coverage area: Not all purifiers work for all spaces. Ensure the purifier is suitable for the size of your room or space.
4. Certifications: Trusted certifications ensure that the product meets safety, performance and energy efficiency standards. The standard certifications to look for include the Asthma & Allergy Friendly Certification, Energy Star Rating, and RoHS Compliance (Restriction of Hazardous Substances).
5. Noise levels: Many air purifiers produce a low hum or fan noise. For bedrooms and offices, choose models with sleep or silent modes that operate below 30 dB to ensure uninterrupted rest or work.
