Compared with air fresheners, air fresheners conceal all polluted air with its fragrance. While GOODAIR Royal has the advantage of absorbing all pollutants such as foul odour, chemical gases, fumes emitting while heating the car dashboard. The indoor air is therefore pure and healthy keeping kids and families safe. Indoor air pollution refers to chemical, biological, and physical contamination, it could be up to 10 times worse than the outdoor air.
