Under door odor blockers are designed to fit snugly under doors, preventing the passage of air, dust, and, importantly, odors. Made from a variety of materials, including foam, silicone, and fabric, these barriers effectively seal the gap between the door and the floor. This not only keeps smells contained but also reduces drafts and helps maintain consistent room temperatures. By preventing odors from entering or escaping rooms, these products ensure that each living space remains fresh and inviting.
