Spraying deodorant and cooking can make your air quality dangerous so I got a Govee smart air quality monitor and purifier. Now when I burn food in my kitchen my air quality monitor picks up that the air is not safe to breathe in my bedroom. It then turns on my air purifier which filters the air and my air quality returns to safe levels. It means that my air purifier is only on when it needs to be which is better for my lungs and the planet.
