Because the air quality was the absolute best right up there with the central heating system.
Taking a vacation in the fall is something that me and my wife do every year. We usually do it right at the end of September when the weather is cooling off and we can get a week off from work. This year we decided to take our vacation back east where my wife grew up, and we stayed in a hotel in the city. It was a really great time we had and the hotel was even better. They had the best central heating in there that I think I have ever experienced. Back east it is getting really cold at night this time of the year, and we were grateful that they had such wonderful central heating. Also, on top of the great central heating they also had great air quality. Hotels in the city sometimes suffer from bad air quality because of it being in a busy city area, but this hotel must have had something similar to a whole home air purification system or something. Because the air quality was the absolute best right up there with the central heating system. When we got home, we were really thankful for the wonderful time we had and the great hotel we got to stay in. Our central heating at home is not as good, but it does the job. And the air quality here at home is also not as good. It got us thinking that we may want to invest in a whole home air purification system.
