HEPA filter get solid particles in the air while carbon filter gets gaseous pollutants. This purifier has a Clear Air Delivery Rate(CADR) of 350 m³/h.

This purifier is also fully compatible with Google Home and Alexa. So you can control it with voice commands issued from your Smart home speaker. Additionally, Wyze has its own mobile App for remote controlling the Air purifier and also contains some useful allergen-specific information.
