Air purifiers help reduce smells and pollutants in your home and leave your house smelling fresh. Sciaire Essential Air Purifier is easy to use and makes the whole room odorless. I have a large living room and its windows open to a busy NYC street so the smells come in and it’s terrible. But with this air purifier my room is left with no stinky car exhaust fumes it’s all neutralized. The filter is easy to change and shows you how much dust and dander has been collected especially if you have a pet. This air purifier is so quiet that you don’t even notice that it’s working so it’s great for a bedroom with light sleepers.
