As the mercury dips in North India, the air quality has also taken a nosedive, plunging the AQI levels into the ‘extremely hazardous’ category.

Thick smog blankets cities, making it essential to discuss clean indoor air, which leads us to air purifiers – a rapidly growing necessity in homes and offices.

Understanding how to choose the best air purifier in 2023 can make all the difference to your health and well-being.

Why Air Purifiers Are Essential

Air purifiers have transitioned from being a luxury to a fundamental need, especially considering the recent spike in air pollution across North India.

The hazardous AQI levels pose a significant health risk, and air purifiers work silently in the background to remove contaminants from the air in your living space.

How to Choose the Right Air Purifier

  • Understand the Filters: Modern air purifiers come with multiple filters, including HEPA filters for particulate matter, activated carbon filters for odours, and more. The right combination can capture pollutants to microscopic levels.
  • Consider the Room Size: The efficiency of an air purifier is partly determined by the size of the room it’s intended for. Each purifier is designed to filter air effectively up to a certain area measurement, so match the purifier’s capacity with your room’s square footage.
  • Check for CADR Rating: The Clean Air Delivery Rate (CADR) indicates the volume of filtered air an air purifier produces. A higher CADR means the unit can filter more air in less time, ideal for regions with extremely poor air quality, like North India recently.
  • Noise Levels: Since air purifiers are often used in living spaces and bedrooms, opt for a device that operates quietly to ensure it doesn’t disturb your daily activities or sleep.
  • Smart Features: With the advent of smart homes, many air purifiers now offer features like air quality sensors, auto-adjust modes, and remote controls via apps. These can offer convenience and peace of mind.

What factors should I consider when buying an air purifier in 2023?

When purchasing an air purifier, consider the type of filters it uses, the size of the room it will serve, the Clean Air Delivery Rate (CADR), noise levels for comfort, and whether it includes smart features like air quality sensors or app connectivity for convenience.

How does room size affect the choice of air purifier?

Room size is critical as each air purifier is rated for a maximum effective coverage area. Ensuring the purifier’s capacity matches or exceeds your room’s square footage is essential for optimal purification efficiency.

What is CADR and why is it important for air purifiers?

Clean Air Delivery Rate (CADR) measures the volume of filtered air an air purifier produces. It’s crucial because a higher CADR means the purifier can clean more air faster, which is particularly important in areas with high pollution levels.
