How To Make And Use A Sploof To Stay Discrete

How To Make And Use A Sploof To Stay Discrete
December 31, 2019

Although cannabis is gradually being legalized, the stigma surrounding its use persists up to this day. Hence, smoking sessions are kept as discreet as possible to avoid side-eye glances from neighbors. Using a sploof, in this case, is helpful in preventing the distinct and lingering scent that is often an unwitting disclosure of the ongoing session.

A Primer On Sploofs

This handy contraption acts as a filter that traps unwanted odors from escaping into the air. Sploofs are tubes packed with filtering agents such as dryer sheets or activated charcoal. Smoke that passes through are diffused and purified in the scent-absorbing agents. Hence, it eliminates the smell of cannabis from lingering in the air.

Classic Tissue Roll Sploof


Aside from serving its primary purpose – muffling the strong odor of cannabis – sploofs are packed other advantages to amplify the reasons why it is a must-have in every smoker’s kit.

Stealthy Smoking

Authorities are all too familiar with the distinct scent of cannabis that can be smelled even from a good distance. Undeniably, this smell wafting in the air can throw off an otherwise excellent session by spurring paranoia of getting caught. A quick fix would be to use sploofs to neutralize the smoke’s odor. This way, the buds can be relished privately.

No Foul Odors

Non-smokers sharing the same space with a smoker would also benefit from the use of sploofs. This is because more often than not, the smoke smells pungent to those who are not big fans of the weed. With sploofs, both parties could coexist without being a nuisance to one another. The smoker gets to relish the weed without worsening the quality of air in the room, and the non-smoker would not be bothered by the foul odor of second-hand smoke.

Inexpensive And Easy To Make

While there are sploofs readily available in the market, some still prefer DIY versions to save money. After all, store-bought sploofs cost around $20 whereas DIY ones only need a couple of dryer sheets which costs 30 cents per piece. This is because most materials required in making sploofs are already found in the household. All that is needed is a bit of creativity, time, and patience to work on the craft.

Even making sploofs is a way to save time because this nifty add-on is far from being complicated. It only takes five minutes or less to assemble an inexpensive yet efficient apparatus for filtering the skunky odor of weed. There is no need to drive around looking for shops selling this elusive merchandise or wait for the delivery from online stores. By making a sploof, its benefits can be harnessed immediately.

Portable And Customizeable

When smoking on the go, customizing a pocket-sized sploof is quite easy. Simply choose a vessel that is small enough to be portable and fill it up with filtering agents. Customization is among the best benefits of a homemade sploof as it allows tailoring the craft to suit specific needs and preferences.


One of the beauties of making sploofs at home is that it could benefit the smoker and the environment at the same time. Smoke worsens the quality of air so by using sploofs, this detrimental effect is mitigated. Apart from that, there are countless ways to make this paraphernalia by recycling old materials such as plastic bottles, toilet paper tubes, or pretty much anything as long as it can hold dryer sheets inside. This makeshift sploof could be used repeatedly by replacing the soiled dryer sheets inside.


Despite its considerable benefits, DIY sploofs are not without flaws. However, these drawbacks could be easily remedied.

Short Lifespan Of Paper Tubes

Re-using empty paper towel tubes as the body of a sploof is an excellent initiative to recycle. Keep in mind, though, that this material is made of paper and meant to be disposable. As such, it does not last long. Repeatedly exhaling smoke into the tube dampens and wears it out fast because of the moisture.

The better alternative would be to use plastic bottles. Papers are biodegradable whereas plastic bottles are not. Since this material lasts for a long time, it could be used repeatedly. It does get dirty and needs to be cleaned. Other than that, the only thing that also needs to be done after prolonged use is to replace the dirty filtering materials.

Can Only Dispel Smoke Exhaled Into It

Sploofs hide the weed’s smell that passes through it. It does not neutralize the scent of the smoke coming out of joints, bongs, and pipes as these are dispersed directly into the air. When not immediately addressed, the odor could linger and attract unwanted attention.

For experienced smokers, doing one-hit smokes from bongs and immediately blowing it through sploofs minimizes the lingering odor. But for novices who are still getting used to bong rips, air fresheners are the ultimate salvation. Although this does not eliminate the smell, it can help mask the odor with a pleasant fragrance that would hopefully confuse the olfactory sense of authorities or nosy neighbors.

Making DIY Sploofs

Brand-new sploofs can be made in under five minutes and minimal effort. Using recycled items is not only budget-friendly, but the choice of specific materials could also be eco-friendly.


The materials required in making this nifty add-on are mostly household items. Dryer sheets and activated charcoal, though, are components that need to be procured.

Filtering Agent

The filtering agent is at the core of sploofs and what makes it function. It is the component that absorbs and traps the odor molecules of the smoke. The secret to its efficiency lies in its porousness. And, combining the use of dryer sheets and activated charcoal makes it possible. Using either of the two would also work well.

Granular activated carbon
  • Dryer Sheets. Aside from being an inexpensive filtering agent, most households already have dryer sheets for laundry purposes. Its thick weaves make it hard for smoke particles to pass through. This effectively filters and traps odor molecules and thereby allowing only unscented air to leave at the other end of the tube. Depending on the brand, dryer sheets are also relatively cheap. A piece only costs about 30 cents.
  • Activated charcoal. This material is made from natural resources like coal, bamboo, and wood that are “activated.” by being subjected to high temperatures. Effective, this process widens its surface area making it more porous. As such, it efficiently absorbs odor particles. A jar of activated charcoal costs around $10. Although it can be somewhat pricey compared to dryer sheets, this alternative is significantly more effective. Nonetheless, a small jar goes a long way, so not many are needed to achieve the desired result.
  • Paper coffee filters. In the absence of dryer sheets, coffee filters are a suitable alternative. Its thick weaves are comparable to dryer sheets. Although it is somewhat to a lesser degree, it could still screen and trap odor-causing particles. Forty pieces of these paper filters could be bought for as low as $5.
  • Cloth rags. Cloth rags could also serve as a filtering agent when in a pinch. Lightweight cotton clothes that are thin and breathable are the most ideal as it lets the smoke escape yet thick enough to hold other filtering agents between layers. Since it gets soiled, repurposing old cloth rags for this purpose extends its usability before discarding.


Tubes serve as the body for spoofs. The size depends on its purpose and the user preferences. A small yet sturdy base allows for portability. On the other hand, a larger vessel is more suitable for maximum efficiency. Regardless of shape or size, as long as the tubes are hollow and can contain filtering agents, it would work fine.

Empty toilet paper rolls
  • Toilet paper tube. It is virtually impossible for a household not to have this biodegradable item. Since it is commonly discarded, repurposing for sploof makes it extremely cost-effective, and it could be used for two smoking sessions.
  • Plastic bottle. Of all the materials that could be used for the tube, plastic bottles are the best option. It already has a mouthpiece that is convenient for exhaling smoke. Its size is customizable and allows for bigger exhaust for better dispersion if desired. Furthermore, its transparent body offers a clear view of the filtering agents inside. Once it turns dark and dirty, then it is time to scrape and replace. Lastly, plastic bottles are guaranteed to be sturdy vessels that could withstand the test of time, regardless of how frequent it is used.
  • PVC pipes. Customizing to the preferred size and color are made easy with PVC pipes. Although using it as a base cost more than usual, its durability and long lifeline covers for it. The only downside is that it is highly unlikely to be portable because of its bulkiness.
  • Lip balm tube. In cold regions, lip balms are a lifesaver. The packaging it comes in could also be used, and it is discreet. However, due to the minuscule size, it is quite impossible to put dryer sheets inside. So, activated charcoal should be used instead.
  • Empty prescription bottle. Another easy way of concealing sploofs is by using empty prescription bottles. Poking holes at its bottom will do the trick. Because it is slightly larger than lip balm tubes, it could be filled with both dryer sheets and activated charcoal.


Binders secure the exhaust of the sploof. The only requirement for this component is that it must be able to keep everything intact.

Elastic rubber band ball
  • Rubber band. This is the best binder that could be used. It is adjustable, long-lasting, and securely fast the cover of the exhaust in place. Moreover, it could be easily removed and attached when changing dryer sheets.
  • Duct tape. For disposable sploofs made of paper tube towels, tapes could be used instead of rubber bands. The adhesive will keep the filters in place while trapping the ashes and other small particles trapped inside the sploof. However, one drawback is that it cannot be reused as it loses its adhesive properties as time passes by. Removing it could also damage the paper tube.

A Pair Of Scissors Or Cutter

Anything that can cut through the preferred tube material is needed to reduce it to the desired length. Whether it is a pair of scissors, cutter, or knife, make sure that it is sharp enough to cut through the material effortlessly. If using PVC pipes, a hacksaw is most ideal.


  • The first thing that needs to be done is to prepare the base of the sploof. It must be a tube large enough to hold the filtering agents.

Toilet paper tubes. Ensure that no loose tissue is left on the cardboard tubes. Other than that, no additional preparation needs to be made.

Plastic bottle. It must be cleaned and dried thoroughly. Then, cut the bottom half of the bottle. Keep the mouthpiece intact. The large opening at the bottom will serve as the passageway for the exhaust.

PVC pipes. After cleaning it, cut it 5 to 8 inches long, depending on the preferred length. Sand both ends of the tube to make the edges smooth.

  • Place a dryer sheet on one end of the base and secure it in place with a rubber band or tape.
  • Insert just enough dryer sheets or coffee filters inside the sploof to fill about 2/3 of the container. Make sure the filtering agents are tightly packed but loose enough for air to pass through. It can be tested by blowing into the sploof, and while there is resistance, it is still possible to exhale.
  • An optional but recommended step is to add a spoonful of activated charcoal in between layers of the filtering agent. This will work wonders by enhancing the odor-absorbing ability.

Tips On Using And Maintaining The DIY Sploof

  • After inhaling smoke, blow it through the open end of the sploof. The smoke will travel through the filtering agents inside and exit through the exhaust on the other end. The result is an odorless or a subtle but pleasing smoke depending on the filters used.
  • The filtering agents inside the tube will end up looking dark with frequent use and need changing. This is due to the trapped ash, resin, and other impurities from the smoke. It is easily observed when using a plastic bottle. That is not the case with PVC tube. In this case, the telltale sign is when it starts to exude a foul odor.
  • Cardboard tubes will end up soggy due to excessive moisture from the exhaled breath. By then, it is time to discard.
  • After using for a while, the interior side of a plastic bottle gets soiled. It could be cleaned after taking out the filters using soap and water.

Possible Alternatives

In circumstances where the creation of makeshift sploofs is not possible or not preferred, alternatives that can mask or minimize the cannabis smell may be used to maintain privacy.

Essential Oils

Essential Oil in Small bottles

These oils are derived from plants such as jasmine, bamboo, and lemon. While it is primarily used in aromatherapy for its stress relieving qualities, its fragrance may also be used to mask the scent of burnt weed.

However, take note that it does not eliminate the foul smell; it only conceals it. To aid in diffusing the scent, add about 2 to 3 cups of water and 3 to 10 drops of essential oil in a scent diffuser. Then, provide as much ventilation as possible by opening all windows and turning on the fans. Doing so will get rid of the smell and increase the flow of fresh air into the room.

Respirator Filters

Carbon Filter

Otherwise known as air filters or carbon filters, these are made from pure activated carbon. Specific air filters such as High-Efficiency Particulate Air (HEPA) filters can vacuum the tiniest molecules in the air. Respirator filters are also used when growing cannabis plants indoors to lessen the conspicuousness of the scent it exudes. However, this option is considerably pricier than others. Nonetheless, it is capable, efficient, and durable.

Air Fresheners/Scented Candles/Incense Sticks

Fragrant Aroma Lamp

When all else fails, the last resort would be to use air fresheners, scented candles, or incense sticks. These three products do not absorb or eliminate the smell; nonetheless, it can keep the scent at bay by masking its odor.

Air freshener may be the least effective of the three as it covers a limited area. Hence, this option is recommended for small rooms only. Scented candles, on the other hand, emits scent-infused smoke that can cover larger areas. However, for a more natural scent, incense sticks made of dry herbs such as sandalwood and sage may be the best pick.

Store-Bought Sploofs

If homemade sploof is not an option or preference, commercially-produced ones can be used. The store-bought variant tends to be more sturdy and sophisticated-looking compared to DIY ones, but it is also more costly.

Sploofy. Praised for its eco-friendly ideals, Sploofy is the leading commercial brand. The carbon filters inside it use dual-layer activated HEPA carbon cartridge with a 99.97% efficiency rate.

These filters last up to 300 uses and are easily replaceable. Its shatter-proof housing comes with a design that allows for the adjustment of the airflow. It costs $19.99 per piece.

Snubbz Smoke Silencer. Akin to Sploofy, Snubbz also comes with a HEPA carbon cartridge which effectively filters out the smell of the herb. It comes in a tetra pack that looks like a child’s drink.

A cherry topper on top the silicon mouth pad allows the snuffing of smoke from bowls. The Smoke Silencer does not use replaceable cartridges. Instead, it is discarded after 150 to 250 uses. It could be bought for just $13.50.

SmokeBuddy. Available in various sizes, this disposable sploof neutralizes odor and eliminates smoke in an instant. Smoke Buddy Jr., the smallest and yet the most famous, comes with a keychain and caps for safe keeping.

It uses concentrated activated carbon to filter the smoke and neutralize its odor. It is sold in online shops at $19.95.

Nifty Tool For Stealth Smoking

Relishing the smoke of lighted cannabis buds without worrying about getting caught is a privilege that only a handful of smokers get to enjoy. Not only that but even in places where smoking weed is acceptable, its scent could bother other people. Using a sploof addresses these concerns.

Commercial sploofs are available in local dispensaries. It could also be bought from online retailers. For some people, making it at home is a matter of economics. On the other hand, it is also a viable option when one is needed, and there is no time to buy.

DIY sploofs are not challenging to make, and it is quite fun too. It may look crude, but it could function just as well. It may not be as efficient, but it could still serve the primary purpose of trapping cannabis odors.
