Dusty air in the cooling vents

Since I recently moved into a modern part of the neighborhood, I have been looking for a gym to go to that was close by.  I usually workout about 4 to 5 times each and every week.  I workout in between shifts at work so my workouts only last about an hour or so.  The first gym that I went to near my home was not all that bad! It had lots of free weights and machines.  The one thing I did not love about this gym is that the cooling system was very lacking.  There was a strange stink coming from the AC vents in the ceiling.  I also observed that there was a large amount of dust coming out of the AC vents also.  If there was dust coming out of the AC vents, I couldn’t imagine how awful and dirty the cooling system ducts were.  The more I thought about it the less I wanted to go back to that particular gym.  I absolutely shouldn’t be inhaling all that dust and pollutants while I am trying to workout, not to mention the air circulation makes the whole locale stink bad.  So after a few weeks I had an opportunity to check out some other gyms near my residence.  While driving through another section across the town, I stumbled on the perfect gym for me.  When I walked into the building, the very first thing that I observed was how cool and especially clean the locale was.  The cooling system in this place was absolutely wonderful.  There was no funky smells and the air circulation was fantastic.  I examined the AC vents on the ceiling and they were all sparkling clean and fresh looking.  I had found my modern gym.
