Air purifiers are one of my favorite HomeKit accessories. Even though I live in an area with pretty decent air quality, I keep them running in our home to help clean the air for my family, especially in the spring. The problem is that most of them look like medical equipment. I love the Smartmi E1, and it effectively ends the era of ugly appliances. It is hands-down the best-looking HomeKit/Apple Home air purifier on the market.
