Blaux Portable AC Traditional AC units are outdated. They are expensive to install and even more costly to run. They look ugly and are difficult and dangerous to clean. You can’t even move them around the house with you or take them outside! Fans can be cheaper, but they only blow around the air – what if the air is too hot already? It’s actually making you feel worse when the hot air is moving around your hot room! Plus they are VERY noisy.
