Our picks for air purifiers to buy this winter

According to Swiss air quality tech company IQAir, Bangladesh has an air quality 16 times worse than the World Health Organization's (WHO) guidelines. The problem only gets worse during winter, when cooler temperatures trap pollution closer to the ground, and different heating methods increase the already-choking levels of harmful particles in the air.

This spike in air pollution makes it even more critical to prioritise breathing clean air. Prolonged exposure to polluted air can lead to respiratory issues, fatigue, and long-term health complications, making air purifiers an essential addition to any home. These devices help remove pollutants, giving you and your family safer air to breathe.

But with so many options in the market, which one should you choose? Here is a list of our picks of air purifiers you can buy for the upcoming winter, with options for every budget. Please keep in mind that pricing and availability may vary across stores.
