Sploof

You might be thinking wtf is a sploof? Sounds weird right? Well a sploof is a homemade or store-bought device used to help filter and mask the smell of cannabis smoke. It’s especially useful for people who want to smoke discreetly, like in apartments. college dorms, your parents house or places where cannabis smoke might be unwanted or frowned upon and you want to hide the smell of cannabis.

A traditional DIY sploof is super simple to make: you take an empty toilet paper roll, stuff it with dryer sheets, and secure one sheet over the end with a rubber band. When you exhale your smoke through the sploof, the dryer sheets filter the smoke and help neutralize the odor, leaving the air smelling more like laundry than weed.

Commercial sploofs, on the other hand, often use activated carbon filters to absorb the smoke particles and odor more effectively than dryer sheets. These devices are typically more efficient and last longer but can be a bit pricier than the DIY version.

If you’re trying to keep the smell down while smoking indoors, a sploof can definitely be your best friend!

How to Make an Advanced DIY Sploof Using a Powerade Bottle and Activated Carbon Filters

For a more effective sploof, combining activated carbon with dryer sheets helps mask cannabis smoke odors significantly better than basic versions. Here’s how to make one:

What You’ll Need:

• Powerade bottle
• Dryer sheets (e.g., Bounce)
• Activated carbon (from the fish tank aisle)
• Paper towels
• Drill or nail for airflow holes
• Chopstick or long stick for stuffing

Instructions:

1. Prep the Bottle: Wash the Powerade bottle, remove the label, and dry it. Drill or poke 7 small holes at the bottom for airflow.
2. First Layer: Crumple 8-10 dryer sheets and stuff them into the bottom of the bottle using a chopstick or stick.
3. Activated Carbon: Rinse 1 cup of activated carbon in a strainer, dry slightly, and wrap small amounts into dryer sheets like a “burrito.” Stuff these pouches into the bottle.
4. Final Layer: Add another 8-10 dryer sheets on top to finish the filtration.
5. Use and Store: Keep the cap on when not in use, and exhale smoke through the open end. The dryer sheets trap large particles, while the activated carbon absorbs odor molecules, leaving cleaner, less smelly air.

How Do They Work?

The idea behind a sploof, especially one made with activated carbon and dryer sheets like Bounce, is that when you exhale cannabis smoke through the device, the filters trap the smoke particles and greatly reduce the smell.

Cannabis smoke is made up of both solid particles (like ash) and gaseous compounds (such as terpenes and cannabinoids, which carry that pungent aroma). When you blow smoke into a sploof, the Bounce dryer sheets act as an initial physical barrier that captures larger particles and provides some odor-neutralizing properties due to the fragrance infused into the sheets. But the real work happens when the smoke reaches the activated carbon.

Activated carbon is extremely porous, giving it a massive surface area—just one gram can have a surface area of up to 3,000 square meters! As the smoke passes through, the carbon adsorbs (not absorbs) the smaller, odor-causing molecules through a process known as adsorption, where those particles cling to the carbon’s surface. This traps the smelly compounds, preventing them from escaping and reducing the smell that lingers in the air.

By the time the smoke exits the sploof, the combination of Bounce dryer sheets and activated carbon has neutralized much of the odor. What you’re left with is cleaner, less noticeable air—perfect for keeping your smoke sessions discreet!
