During the Covid-19 pandemic, people across the country have turned to air purifiers to help clean the air in their homes, removing indoor air pollution like dust, dirt and other allergens. Air purifiers were also sought after during wildfire season this summer. Some shoppers searched specifically for air purifiers with high efficiency particulate air, or HEPA, filters, while others looked to purchase affordable models or ones for small spaces.

Many brands launched new air purifiers in 2021, like Bemis, which debuted its first line of air purifiers, and Coway, which introduced the 250S air purifier. Air purifiers were also on sale during shopping holidays like Amazon Prime Day, Black Friday, Cyber Monday and more.
