Abstract
Example embodiments use hydrophilic substances to absorb moisture from the air passing through the vent cover. The vent cover is recommended to be used along with a fan to regulate the air flow through the vent cover. The vent cover has holes, and the holes are filled with the hydrophilic material (i.e., hydrogel or polyacrylamide beads). Once enough moisture from the air passes through the vent cover, the vent cover seals itself and prevents air from flowing. The hydrophilic material allows the water to evaporate over time and thus effectively removes the seal.
