Before you plug your air purifier in, make sure to check that the filter isn’t wrapped in plastic inside the machine. I probably don’t need to tell you how I know this is a very important first step. The purifiers we recommend are smart home models, so the next step will usually involve downloading the manufacturer’s app to your phone and connecting the air purifier to the app as well as your home’s Wi-Fi.
