Purge Natural Purge Bags are a super easy and convenient way to maintain a fresh, dry, and odorless environment. Their larger form provides better odor control in small spaces such as offices, closets, and cars. Purge Bags work by utilizing the only active ingredient found in the bag - activated charcoal derived from bamboo. The bamboo found in Purge Bags are heat activated to produce many micro pores that increase the surface area. These pores effectively trap and absorb odors and excess moisture that help clean and freshen the surrounding environment. Purge Bags are effective in neutralizing stubborn smells such as those caused by smoke, pet urine, litterboxes, gym shoes, and more! Purge Bags are a natural alternative to other deodorizers that contain chemicals that are not healthy for the environment or your health. To use your Purge Natural Purge Bags, place your bags inside the affected area. It is recommended to leave them in the area overnight. Although Purge Bags are designed to help in areas with excess moisture, they will face diminished performance in wet conditions. Purge Bags are more effective in environments such as your car, office, or garage. After a couple of uses your Purge Bags may need to be reactivated to clear the pores. Simply place your bag outside in the sun for at least an hour monthly. With proper care, your Purge Bags should last you up to two years. After about two years you can compost the contents of your Purge Bag or use them as an additive to your soil!<br><br>Contents: One Medium Purge Bag.
