Amazon unloaded a whole slew of new smart home devices back in late September, but a smattering of products are still trickling out ahead of the holidays. Certainly a Smart Air Quality Monitor isn’t as exciting as, say, a giant Echo Show, home robot or even a thermostat, but the at least the inherent value in such a product it clear.

The device is designed to measure the air for particulate matter, including carbon monoxide, dust and volatile organic compounds – essentially chemicals in the air that could harm you. There’s also built in temperature and humidity detection. As the product page notes, the device doesn’t have a built-in microphone or speaker, meaning it relies on a connected Echo device or the Alexa app to send alerts when something is off. So, one fewer microphone in your house. That’s a plus.
