ONGROK 2 Pack of Replacement Filter Cartridges

ONGROK 2-Pack Replacement Filter Cartridges

The Replacement Filter Cartridges for the ONGROK Personal Air Filter are paper-based and eco-friendly. Each filter has an integrated hydrophobic screen, preventing moisture buildup, which keeps each filter lasting longer. Once the filter capacity is used up, swap it out by fitting the filter onto the bottom of the silicone mouthpiece.
