I was diagnosed with mild asthma as a kid. I don’t take any medication, yet knowing that illness lives in my respiratory system means I try to be especially conscious of what I’m breathing. Air quality is difficult to control, so a personal air purifier is something that fundamentally interests me. Looking not unlike the USB microphone I bought and swore I’d one day use for podcasting, Wynd filters allergens, dust, smoke and other pollutants. It can operate automatically, or you can manually adjust the output by twisting the top.
