It all depends on how strong the odor is. Once you notice the return of any unpleasant smells, it may be time to refresh the activated charcoal. Expose the DivinAir Charcoal Bag to sunlight for 3-5 hours to replenish its natural deodorizing capabilities. Some people do this once a month. Each unit lasts approximately 6-10 months before replacement is needed.

Formaldehyde is a chemical commonly used in the manufacture of pressed-wood furniture (particleboard, fiberboard, etc.), carpeting, adhesives, coatings, certain fabrics, paper products, and more. Formaldehyde coverts into a gas at room temperature. People with sensitivities may suffer headaches, dizziness, and agitated eyes, nose, and throat when exposed to it. Activated charcoal is effective at eliminating these gasses.
