The charcoal Purifying bag is placed exactly where the stench comes from. Either next to the trash can, the shoe cupboard or in the car. Wherever you want fresh air, you can put it down. A short time later the air is clean and refreshed. In order to be able to use the bag permanently, it is advisable to place it in the sun about once a month for one hour, so that it can "recharge" itself and provide fresh air again. The bag can be used permanently for about two years and afterwards you can use it for other purposes by simply cutting it open and scattering its contents in the garden in the flower beds. This provides your garden's soil with valuable nutrients. Click on its official website and get it with lot of Discount: http://breathe-green.over-blog.com/2019 ... g-bag.html
