AAVI, Pro 300 is a powerful and novel fresh air purifier, which integrates the car design language into the design of home appliances, which coincides with the performance of the fresh air blower, giving people a sense of speed. The tilt control panel and hidden screen design greatly enhance the user experience. The fan blade design avoids dust pollution in the air. The pull-out activated carbon box can facilitate the user to replace the filter material. The hidden handle design in the other direction does not destroy the overall design, but also facilitates the user to push and pull the device.
