Airmega's air-cleaning demo at CES 2017.

Coway makes Airmega air filtration systems that suck allergens out of the air in your home. And now it’s making the devices easier to control, with the integration of Amazon Alexa voice commands, starting in mid-January.

On top of that, the company will ship a graphite version of its filtration system in mid-February. The graphite unit will come in the Airmega 400 ($750) and 400s ($850) models. The Alexa integration is one more example of how much easier it can be to control devices when they become part of the Internet of Things, which is making everyday objects smart and connected.

With Alexa, you can now ask Airmega for updates on indoor air quality, filter lifetime, fan speed changes, timer setup, and more. This is the first step to integration across all voice-activated platforms. Google Home will be up and running by mid-2017.
