Last week our classroom had a terrible smell. We couldn't figure out what the smell was and we kept on locating where the smell came from. We find out that the smell came from the ceiling. It was like a dead rat and was already there for days. The smell was really disturbing so my cousin took their virus washer and placed it inside the classroom. A virus washer is a machine that cleans the air protecting people from germs and viruses. If you have no idea what it looks like, it looks similar to a portable dehumidifier. I thought the machine wasn't effective but in just a matter of minutes the bad smell was gone.
