Yes, it does! Since a person is mostly indoors and spends around 80% of their time there, it matters a lot. Even small children and babies are mostly at home, and they need good air for better health. We cannot be able to control the air outside, so it is better to control the air where we spend the most amount of time. This way, we can protect the ones close to us and give them a healthy environment to live in. According to research, it has been noted that indoor air generally tends to have more pollutants than the air outdoors.
