Budget air purifiers under ₹5,000: Do they deliver on pollution promises?

Rising air pollution levels across the National Capital Region have sparked growing demand for air purification devices, with budget-conscious consumers increasingly turning to low-cost models priced under ₹5,000. However, experts caution that affordability does not always translate to effectiveness in combating hazardous air quality.

Before purchasing a budget air purifier, consumers should familiarize themselves with critical technical specifications. The filter quality is paramount—devices with genuine HEPA filters are more effective at capturing pollutants than cheaper alternatives. The Clean Air Delivery Rate (CADR) rating, which measures how quickly a purifier can clean air in a given space, should be carefully reviewed to match the device's capacity with the room's dimensions.

Room size compatibility remains a frequently overlooked factor in purchase decisions. A purifier with insufficient capacity for a larger room will operate inefficiently and fail to deliver noticeable improvements in air quality. Consumers should calculate their room's cubic footage and cross-reference it against the manufacturer's specifications to ensure proper coverage.

Experts recommend balancing cost considerations with performance expectations. While budget purifiers may offer basic filtration, they often require more frequent filter replacements and may not remove finer particulates effectively. Investing slightly more in a mid-range model with verified CADR ratings and higher-quality filters often proves more economical in the long run, delivering better protection against outdoor pollution infiltration.
