Laser focus: Kaiterra Laser Egg + Chemical

Kaiterra's Laser Egg + Chemical is a HomeKit accessory that focuses purely on the air quality in your home. The Laser Egg's onboard optical sensors scan your air for dust and VOCs, including carbon monoxide, methane, and many more. However, the Laser Egg does not feature an audible alarm — it can only send notifications to your iOS devices, meaning it is meant to be a secondary way of monitoring, and you should always have an actual alarm present.
