The last time I had to get a roommate, it was a total disaster. I did not properly screen the applicants, that was all my fault, and ended up with a terrible seed. This time around I was a lot more stringent, to made sure whoever rented my spare room was neat, clean, in addition to quiet. I know I did a fantastic job selecting a roommate this time, because so far there have been no troubles with Ben, my new roommate. Ben is a salesman, and tends to bring his work home with him most days. Aside from hogging most of the storage space, he is great. Hank is a traveling salesman, who specialized in air filters, in addition to other products designed to increase the air quality of a home or office. These days several businesses are placing more emphasis on the health in addition to the comfort of their workers. Air quality is one of the industries making a surge. He started off just selling the replaceable air filters, in addition to the more expensive HEPA air filters that met government requirements. He had branched off recently into selling electrically powered air filters, that relied on certain UV technologies to purge bacteria in addition to dust from the air. It sounded like a lot of garbage to me, so Ben set up one of his new model air filters and blocked it in. I have to say that within a hour I could tell the air quality had improved, and I was breathing easier too. By the end of the week I had bought one of the air filters from him and set it up in our living room.
