Naturefresh air purifiers

Three available. Naturally helps remove odors, bacteria, harmful pollutants and allergens. Fragrance free. Filled with just one ingredient, activated bamboo charcoal. Removes toxins from the air, trapping them inside. Unlike Febreeze which ADDS toxins to your air! To rejuvenate, place in direct sunlight once a month for at least one hour. I have a dog and no one has ever complained!
