How to Make a Sploof?

Let us uncover the essence of sploofs, their evolution over time, and the intriguing science behind these DIY marvels.

What Is a Sploof?

A sploof is a crafty device designed for cannabis enthusiasts seeking odor control and primarily created to mask the distinct scent of cannabis smoke.

Crafted from everyday materials, it has become a staple for those who enjoy herbal indulgences without attracting unwanted attention.

A sploof is a filter that traps terpenes, ensuring a discreet and considerate smoking experience.

The Evolution of Sploofs

From its humble origins, often attributed to teenagers concealing their cannabis use from vigilant eyes, the sploof has undergone a remarkable transformation.

What started as simple DIY solutions involving toilet paper rolls has evolved into a diverse range of options.

Modern sploofs now incorporate replaceable filters, eco-friendly features, and enhanced efficacy, reflecting the dynamic progression of cannabis culture and innovation.

Understanding the Science Behind Sploofs

At the core of sploof functionality lies a fascinating science. These ingenious devices work by trapping cannabis terpenes, the aromatic compounds responsible for the distinctive smell of cannabis smoke.

Materials like activated carbon and dryer sheets act as filters, capturing and neutralizing these terpenes.

By comprehending the intricate science behind sploofs, users gain insights into how these unassuming devices successfully tackle cannabis odor control.

How Long Does a Sploof Last?

Understanding the lifespan of a sploof is crucial for maintaining effective cannabis odor control during smoking sessions.

Filter Replacement

The filter is a critical component of a sploof, often made from paper towels or dryer sheets. After approximately 2–3 smoking sessions, the filter becomes saturated, less effective, and may start emitting odors. Regularly replacing the filter ensures optimal performance.

Core Components

The body of a sploof, commonly crafted from a cardboard tube or plastic bottle, can last for weeks or even months. The elastic band that attaches the filter to the body contributes to the sploof’s overall durability.

Economic Filter Replacement

The economic aspect of sploofs lies in the ease of replacing filters. Since filters are often made from readily available materials like paper towels or dryer sheets, users can quickly and inexpensively replace them regularly.


While filters may need frequent replacement, the core components can endure over an extended period, promoting a sustainable and eco-friendly approach to cannabis odor control.

Crafting a Sploof With Dryer Sheets: A Step-By-Step Guide

Preparing a sploof with dryer sheets is a simple and cost-effective method for DIY cannabis odor control. Follow these six steps to create your sploof:

  1. Select Your Base: Choose between a plastic bottle or a cardboard tube (toilet paper roll) as the foundation for your sploof. A plastic bottle with a wide mouth is preferable for enhanced airflow.
  2. Prepare Dryer Sheets: Gather approximately five dryer sheets. These sheets will be the primary filter to capture cannabis odors during exhalation.
  3. Assemble the Sploof: If using a plastic bottle, cut off the bottom to create an open-ended cylinder. Place the dryer sheets inside the tube or bottle, ensuring they are not overly compressed.
  4. Secure the Filter: Cover one end of the tube or bottle with a dryer sheet, pull it taut, and secure it with an elastic band. Trim any excess material for a neat appearance.
  5. Final Touch: If using a plastic bottle, consider cutting several small holes (5-10) in the bottom for better airflow. This step is crucial for optimizing the sploof’s effectiveness.
  6. Ready for Use: Your sploof is now complete. Exhale the cannabis smoke through the open end, allowing the dryer sheets to filter the odors. Enjoy discreet smoking sessions with minimized cannabis aroma.

Making a Sploof Without Dryer Sheets: Resourceful Alternatives

When the desire for discretion meets a lack of conventional materials, resourcefulness becomes the key to crafting a functional sploof.

Essential Components

Before delving into alternative methods, let’s gather the essential components you’ll need for a dryer-sheet-free sploof:

  • Container: Begin by selecting a container or bottle that is both sturdy and hollow, such as an empty plastic bottle with the bottom cut off. Opt for a sturdy plastic bottle, ensuring a wide mouth for adequate smoke exhalation.
  • Activated Carbon: Purchase activated carbon sploof, known for its excellent odor-absorbing properties. This can be found in pet supply stores, aquarium shops, or online.
  • Rubber Band or Elastic: Secure the activated carbon to one end of the bottle using a rubber band or elastic. Ensure the carbon is tightly packed, leaving no gaps for air to pass through without being filtered.
  • Duct Tape or Puncture-Resistant Material: Cover the other end of the bottle with duct tape or another puncture-resistant material. This will serve as the mouthpiece of the sploof.
  • Poking Holes: Use a small needle or pin to create tiny holes in the duct tape or material covering the mouthpiece end. These holes will allow the filtered air to exit the sploof.
  • Air Freshener: Choose your favorite scent to help mask the cannabis odor.
  • Paper Towel: An accessible and effective alternative to dryer sheets.

Assembly Steps

  • Cutting the Bottle: Remove the bottom of the plastic bottle, leaving the top (mouthpiece) intact.
  • Adding Activated Carbon: Place a generous amount of activated carbon into the bottom, covering the entire surface.
  • Securing the Carbon: Wrap the rubber band or elastic around the bottle, ensuring the activated carbon is in place. Make sure it is tightly packed to enhance the filtration efficiency.
  • Sealing the Mouthpiece: Cover the top of the bottle with duct tape or another suitable material, creating a seal. Puncture tiny holes in this covering to allow the filtered air to escape.
  • Usage: To use the sploof, exhale the cannabis smoke through the mouthpiece end. The filtered air will exit through the punctured holes, significantly reducing the smell.


Armed with the knowledge of spoof-making, you can now embark on your cannabis journey with confidence, ensuring your smoking sessions remain discreet and odor-free.

Experiment with different materials, embrace the art of crafting your DIY sploof and savor the worry-free highs. Happy smoking!


How effective are sploofs?

Sploofs are effective at reducing cannabis smoke odor, but they won’t eliminate it. They’re best used in conjunction with other odor-control methods.

Can you reuse a homemade sploof?

The effectiveness diminishes over time. Replacing the activated carbon and dryer sheet periodically helps maintain its odor-reducing capabilities.

Will activated carbon remove smoke?

Activated carbon traps and neutralizes smoke particles, making it a key component in Sploofs for odor control.

Can you wash carbon filters?

Washing may reduce the effectiveness of activated carbon. Replace the filter or add a new activated carbon layer to maintain optimal performance.

Do carbon filters clean the air?

Carbon filters can help remove impurities and odors from the air, making them useful in Sploofs and air purifiers.

How do I know if my carbon filter is bad?

A decreased odor reduction or increased smoke smell indicates a declining carbon filter. Regular replacement ensures continued effectiveness.
