4" Clear Diamond-Cut Glass Bubbler vs 5" Glass Oil Burner Bubbler

Buy the 4-inch diamond-cut bubbler if easy cleaning and a see-through body matter most; its removable mouthpiece and stem let you rinse and scrub the whole piece. Buy the 5-inch light bulb bubbler if you want a slightly taller, fully assembled unit with a fixed downstem and a curved burner attachment, and you like the colored bulb look. Both are small borosilicate-style glass pieces with no filtration beyond water, so the real split is cleaning access versus a taller, ready-to-use shape. Owners of the 5-inch describe it as a good hand fit and simple to handle; the 4-inch wins on maintenance.

• Choose the 4-inch diamond-cut bubbler if you want removable parts for thorough cleaning and a clear body so you can watch water and vapor levels.
• Choose the 5-inch light bulb bubbler if you want a taller, fully assembled piece with a fixed downstem and curved burner attachment, in blue, purple or yellow.
