Submitted a quick instruction on how to make an air purifier. Link: https://news.ycombinator.com/item?id=24251509 https://news.ycombinator.com/item?id=24251509 Copy/pasta to help folks: Note: this is not my idea, but I have used it for 2 Cal fire seasons successfully. 1) Acquire a box fan 2) Acquire a large "FPR 10" rated filter from home depot 3) Duct tape filter to the out flow side of the box fan. Make sure the arrows on the filter point in the correct airflow direction. This works dramatically well for very little dollars and can help save your lungs if air purifiers are not available or expensive.
