As the Blaux Portable AC blows out 2.7m/s of refreshing air, it cools the way immediately. This device essentially has two holes. One of these blows unclean and warm wind out that way. Through the additional hole, gas enters at the device where it is cleaned thanks to the filter method. Blaux Wearable AC certainly works for me! I enjoy being outdoors in this summertime, but I have a hard time coping with the energy. Perhaps it's only my creativity, but summers seem hotter than ever.
