Don’t just cover up odors, eliminate them with DampRid Reusable Moisture Absorber with Drop-In Tablet. The 360-degree ventilation system enhances airflow, making it our fastest acting moisture absorber. To use, simply insert an unwrapped tablet into the top of the moisture collection unit. DampRid crystals absorb excess moisture out of the air without use of electricity or batteries, while preventing moisture damage to your valuable possessions. Time-Release Fragrance Technology releases a pleasant scent over the life of the product. Place these moisture absorbers in closets, bathrooms, laundry rooms, pantries, storage units, basements, garages, stored boats and RVs - anywhere damp, stagnant air is a problem. When tablet has dissolved, empty liquid in toilet or drain and rinse out container residue before refilling with new tablet. DampRid Moisture Absorber Drop-In Tablet Refill packs are sold separately.
