With pollution reaching such heights, schools and colleges are often forced to close to protect health.

Look for purifiers with HEPA filters, high CADR (Clean Air Delivery Rate), and additional activated carbon layers for better pollutant removal. Top brands like Philips, Xiaomi, and Eureka Forbes offer reliable models to help breathe safer indoors during these challenging pollution spikes.

Look for energy-efficient models that have the Energy Star certification. This is crucial for continuous use, as it helps reduce electricity bills while maintaining effective air purification.
