A bong is easy to buy and equally easy to use incorrectly. Too much water, weak draws, months without cleaning—most problems have nothing to do with the device itself and everything to do with how you use it. This guide walks you through what actually matters, step by step.
How a Bong Works
The principle is old and simple. Smoke is drawn through water before reaching your lungs. This cools the smoke, traps some of the coarser particles, and makes the draw feel smoother than a joint. That said, smoke remains smoke—burning plant material is and remains the most harmful consumption method. If you want to reduce harm, our article on whether smoking cannabis is healthier than smoking tobacco offers a sober assessment.
When it comes to design, there are essentially two directions. The classic bong has a straight or bulbous chamber with a removable bowl. Percolator models feature additional chambers or screens that route smoke through a second time. This provides more cooling and finer filtration, but makes cleaning more involved. If you prioritize smooth hits, a percolator is worth it. If you prefer simplicity, stick with the classic design.
Setting Water Level and Downstem Correctly

The most common beginner mistake is too much water. As a rule of thumb: the lower end of the downstem—the smoke tube—should sit approximately two to three centimeters below the water surface. If it sits deeper, you’ll need to draw much harder, and water will splash up. If it’s too shallow, the cooling effect is almost completely lost.
Beyond the correct water level, steady, controlled draws are your best defense against splashing. Jerky pulls suck water upward. With percolator models, the ideal level is often lower than expected, since each additional chamber creates its own resistance. Here, it’s worth starting with small amounts and working your way up.
Step-by-Step to the Perfect Hit
- Prepare your material. Break it up evenly—don’t pulverize it. Material that’s too fine slips through the screen into the water; material that’s too coarse burns unevenly.
- Pack the bowl loosely. Don’t pack it down. Pressing too hard restricts airflow and forces you to pull harder.
- Light from the edge. Don’t ignite the entire surface at once. Start from the side. This leaves unburned material for the next draw and keeps the flavor going longer.
- Draw steadily. Slow and consistent pulls as the chamber fills.
- Carb hole or lift the bowl. To finish, either release the carb hole or lift the bowl so fresh air rushes in and clears the chamber.

Cleaning: The Overlooked Part

An uncleaned bong doesn’t just taste worse—it’s a hygiene problem. Biofilms form in standing water within days, and resin builds up on the glass walls. Both end up in your smoke on the next draw.
- After every use: Empty the water, rinse with clear water, air dry. This takes a minute and prevents most buildup.
- Weekly: Soak the bowl and downstem separately—they resin up fastest.
- Deep clean: Add isopropyl alcohol and coarse salt to the chamber as a scouring agent, seal the openings, and shake vigorously. The salt works mechanically; the alcohol works chemically. Then rinse thoroughly with clear water until no smell remains.
- Don’t use the dishwasher. Temperature swings and harsh detergents damage glass and seals.
If you want to filter smoke further, keep expectations realistic. We’ve covered what activated charcoal filters actually do in our article on activated charcoal filters and tobacco research.
With percolator models, plan for cleaning from the start. The extra chambers are hard to reach, and neglecting them for too long makes them nearly impossible to clean properly.
Conclusion
The difference between a harsh hit and a smooth one rarely comes down to the price of the device. It comes down to water level, draw technique, and consistent maintenance. Master these three things, and you’ll get better results from the same equipment, every time.
