Delhi-NCR air quality crisis drives surge in purifier demand; experts advise smart buying

Rising air pollution levels in Delhi and the National Capital Region have triggered increased consumer interest in air purification systems as residents seek to protect their indoor air quality during the deteriorating seasonal conditions.

However, procurement specialists caution that purchase decisions based solely on price can lead to poor value outcomes. Instead, buyers should evaluate five critical technical and financial parameters before making a selection, according to industry guidance.

Key considerations include HEPA filtration capabilities, which determine the system's ability to capture fine particulate matter; CADR (Clean Air Delivery Rate) ratings, which measure purification efficiency; and the physical dimensions of the intended installation space to ensure adequate coverage. Additionally, prospective buyers should factor in the recurring expense of filter replacement and the device's electricity consumption, which can significantly impact total cost of ownership over the product's lifespan.

Experts emphasize that a comprehensive cost analysis incorporating both initial purchase price and operational expenses—rather than headline pricing alone—provides a more accurate basis for comparing air purifier options. This approach helps consumers avoid purchasing systems that prove inefficient or costly to maintain over extended periods.
