BC NewsHow to make a $60 air purifier, as Canada’s wildfires rage onMake your own air purifierPhoto: BC Wildfire service Smoke billows from the Fiftynine Creek wildfire ­northwest of Clinton last week. Wildfire smoke is more toxic than everyday air pollution, and can travel ­thousands of kilometres and linger in the air for weeks. A 2023 study conducted at the National ­Collaborating Centre for Environmental Health found these air ­purifiers can perform as well as commercial air ­purifiers equipped with high-efficiency particulate air (HEPA) filters. While HEPA-equipped air purifiers often cost hundreds of dollars, the materials for these DIY versions cost less than $60. Lung Foundation has logged more than 160 community workshops where participants have built more than 3,200 air purifiers.
