Buying an air purifier? Here are 5 things you should check | Latest News India

Delhi’s air quality has dropped to 226, which is considered poor, and may drop further in the coming days. With such dangerous weather conditions, air purifiers have become a necessity for many families. But with countless options available, selecting the right one can be overwhelming. Here are five crucial factors to consider when purchasing an air purifier adapted for Indian conditions.

Room size and coverage

The first step to selecting an air purifier is understanding the size of the room where it will be used. Most Indian homes feature typical room sizes ranging from 100 to 500 square feet. Consumers should calculate the square footage of their space and select an air purifier capable of effectively covering that area to ensure optimal air quality.

Filtration Technology

Given the specific air quality challenges in India, such as high levels of particulate matter (PM 2.5) and various pollutants, it is vital to choose the right filtration technology. Experts recommend looking for air purifiers equipped with:

HEPA Filters: Proven effectiveness against PM 2.5, dust and pollen.

Activated carbon filters: Efficient in removing gases, odors and harmful chemicals.

Hybrid models: Combine multiple technologies for comprehensive filtration.

CADR (Clean Air Delivery Rate)

Clean Air Delivery Rate (CADR) is a crucial metric that measures the efficiency of an air purifier. Consumers should opt for models with a CADR rating between 200 and 400, which is particularly effective in combating the high levels of pollutants commonly found in Indian air.

Noise level

For anyone using air purifiers in quiet rooms or spaces, noise level is an essential consideration.

Maintenance and Cost

The overall cost of owning an air purifier goes beyond the initial purchase price, typically ranging from Rs. 10,000 to Rs. 50,000. Consumers should also consider:

Filter replacement costs: These can range from Rs. 2,000 to Rs. 10,000 annually.

Power consumption: Look for Energy Star-certified models to minimize energy bills.

Regular maintenance, such as cleaning the pre-filters, can significantly extend the life of the device.

Always check for certifications from reputable organizations such as Indian Standard (IS) or Bureau of Indian Standards (BIS).

Consider purchasing air purifiers with built-in pollution sensors for real-time monitoring of air quality.
