If you have tried to get an air purifier lately, they are likely sold out at stores and online.
With the wildfires burning up and down California, Oregon and Washington state, some are taking matters into their own hands and making their own version of an air purifier.
Some were building their DIY version during the start of the COVID-19 outbreak so they could purify the air.
One 2018 study said your own version could reduce small particulate matter by 75 percent and has several health benefits.
Get a box fan and a couple of air filters and you have your own version and it will be a lot cheaper too.
