Research on wildfire smoke and health shows that smoke is more than just an irritant. It is increasingly clear that older adults<\/a>, pregnant people<\/a> and young children<\/a> face higher risks to their health<\/a>, including premature birth, hospitalization and premature death.<\/p>\n One way to reduce smoke exposure is to stay indoors and create a \u201cclean air shelter\u201d by closing the doors, windows and using an air cleaner to remove smoke and other particles from the air. <\/p>\n However, that is easier said than done for many people. While effective, store-bought air cleaners can be expensive and require pricey replacement filters. <\/p>\n In addition, many homes don\u2019t have air conditioners and easily trap heat<\/a>. Closing all windows means reducing ventilation, and can make hot summer days even more unpleasant. Another option, popularized during the COVID-19 pandemic, is the idea of building your own air cleaner, using easily sourced parts from local hardware stores.<\/p>\n Do-it-yourself air cleaners<\/p>\n An infographic explaining how a DIY air cleaner works. In British Columbia, we started The BREATHE Project<\/a> to study the impacts of wildfires and distribute information about DIY air cleaners.<\/p>\n A 2023 article by the National Collaborating Centre for Environmental Health<\/a> compiled evidence on the effectiveness of do-it-yourself (DIY) air cleaners as an alternative to store-bought units. <\/p>\n The results showed that DIY air cleaners are not only more affordable and accessible, but are equally as effective, as long as the correct parts are used and the room size is taken into consideration. <\/p>\n This includes the use of a MERV-13 filter, a minimum 75-watt box fan, duct tape and a shroud cover on the front corners of the fan. One unit can clean a small room, and multiple units can be used for larger spaces. <\/p>\n DIY air cleaners also help reduce other air contaminants including allergens, mold spores, emissions from woodstoves, respiratory pathogens, dust, and traffic related air pollutants. <\/p>\n The U.S. Environmental Protection Agency found similar results<\/a> in their analysis of DIY air cleaners and determined that the units are safe to use as built<\/a>.<\/p>\n The BREATHE Project<\/p>\n A short clip about the BREATHE Project and the DIY air cleaner worskshops. (The BREATHE Project)<\/p>\n Our team at Simon Fraser University<\/a> partnered with the BC Lung Foundation to share this knowledge about cleaner indoor air with communities across British Columbia. <\/p>\n In 2023, we launched a pilot project in the Lower Mainland to find out if workshops about making DIY air cleaners could be feasible. These workshops were held in community centers, libraries, seniors\u2019 centers and neighbourhood houses, with the average participant being over 70 years old and with at least one medical condition. <\/p>\n We were surprised to find that our workshops were fully booked within days of advertising, and that news of our project was quickly spreading by word of mouth within communities. <\/p>\n We used participant feedback to fine-tune our materials and created instructional videos, and a train-the-trainer manual to guide other organizations on how to host similar workshops. <\/p>\n In 2024, we took the project into B.C.\u2019s Interior Health Authority region, where fires were more frequent and more severe.<\/p>\n We named our project BREATHE<\/a>: Building Resilience to Emerging Airborne Threats and Heat Events and have since added additional resources for communities grappling with the co-exposure of wildfire smoke and extreme heat<\/a>.<\/p>\n![\"An](\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2025\/08\/file-20250801-56-ph7db1.png\")
