Anyone who enjoys cannabis smoke knows that there are some inherent problems that aren't found in other consumption methods.

Unlike edibles, tinctures, and other smokeless options, cannabis smoke quickly takes up space, leaving a lasting aromatic impression. For some consumers, the presence of smoke can land you in trouble, including losing your housing, having the police show up, or upsetting loved ones around you.

This smelly conundrum led to the creation of the sploof, a DIY option that helps minimize smoke and aroma. Today, like many past cannabis creations, the sploof is now also available as a consumer good that you can buy in stores. What is a sploof exactly, and how does one use a sploof for weed smoke?

What is a Sploof?

Why would a consumer need to use a sploof? It’s relatively simple: Weed smells a lot, especially once it’s heated or set on fire. While some consumers love it, the general public doesn’t always feel the same. 

No matter where you stand on cannabis smoke, the pungent aromas are often attributed to the organic compound 3-methyl-2-butene-1-thiol or prenylthiol. Additional plant compounds, including terpenes and terpenoids, help create a more robust aroma thanks to their ability to create a wide array of plant smells and flavors.1 Cannabis smoke can not only smell pungent but often includes hints of gas, pine, soil, citrus, sweets, and a variety of other noticeable aromas. 

These dense smells can be ideal for smokers but not for parents of minors, dorm RAs, police, and countless other individuals who are looking to keep consumers and their airspace smoke-free. Those looking to enjoy cannabis while keeping the air clear can use sploofs. 

The sploof was originally invented to serve as a smoke filter. The original sploof, its name a spin on the spliff, was made using household items, typically a cardboard toilet paper tube, a rubber band, and one or more dryer sheets. 

This DIY invention helped mask the smell of cannabis smoke by having the consumer take a hit, then place their mouth inside the cardboard tube and blow out the smoke, which would then be filtered through the dryer sheets. 

The creation was minimally effective, with better results when more insulation, or dryer sheets, were added. While successful to a degree, the sploof often diminished cannabis smells while leaving the area smelling like clean laundry. 

In recent years, companies began making more sophisticated versions of the sploof using materials dedicated to smoking and smell retention. The legalization of cannabis helped usher in a wave of newer sploof tech that can be purchased from several retailers. 

How Does a Sploof Filter Smoke?

How does a sploof filter smoke?

The sploof is simple yet effective (to a degree). Once assembled, a sploof filters weed smoke through its dryer sheets, reducing the smell released into the air. When packed densely and properly, the cannabis smoke is prevented from escaping the tube after being captured and neutralized by the dryer sheets. Some recommend using scented dryer sheets to increase the chances of pleasant-smelling odors filling the air. 

More sophisticated sploofs are available as well. These options, often manufactured by a company, will typically contain activated carbon and other specialized materials aimed at smell suppression. Some of these materials can be used in homemade sploofs as well. 

Sploofs have varying degrees of efficacy. You likely won’t notice a substantial difference using one or two dryer sheets. However, if one can fit your tube, you may see improved results with additional scented sheets or an activated charcoal filter. 

Store-bought sploofs have greater odds of preventing larger smoke clouds and substantial smells to form. However, the buyer needs to be aware as some products don’t do much better than a DIY device. Be sure to check product reviews before purchasing. 

Why Use a Sploof for Weed?

People have tons of reasons to want to get rid of weed smells.

  • Discretion and Privacy: From needing to cover their tracks or being considerate of those around them, most people use a sploof to smoke with discretion. 
  • Legal Concerns: Some states continue to prohibit the plant, and some states even continue to use cannabis smells as justification to search homes, vehicles, and individuals. 
  • Residential Rules: Many homes and apartments, including public housing and homeowners associations, prohibit smoking cannabis on premises.  
  • Maintaining Professionalism: Smoking during the workday can be a risky prospect, with concerns varying on your job tasks. Those looking to smoke while at work without getting spotted could benefit from a sploof. The concern continues if they’re smoking near the work site or office and worry that smells could build up in a car or enclosed area, and having the aromas linger on their person once back at work. 
  • Family or Roommate Concerns: Some parents want to smoke cannabis without their kids knowing about it. Some young adults who move back home want to smoke and are hoping to prevent their parents from finding out. And some renters may have roommates who aren't as open to cannabis consumption.
  • Just Want Fresh Air: If a consumer doesn’t want cannabis smoke in their home, a sploof can help reduce the aromas. A strong air freshener may also come in handy.

How to Make Your Own Smoke Filter

To make your own sploof at home, you’ll want to have the following items on hand:

  • Cardboard tube (Toilet paper roll is ideal, but paper towel works as well)
  • A rubber band
  • Dryer sheets 

With all the items on hand, you can make your sploof:

  1. Place a dryer sheet over one side of the tube. Secure it in place by placing the rubber band around the sheet and tube, applying enough pressure to hold the sheet in place without denting or caving in the tube.
  2. Insert additional dryer sheets into the tube through the remaining opening. Make sure the area is densely packed to aid in smoke and smell suppression. 
  3. Enjoy when ready!

Dryer sheets can be substituted with paper towels, but if you choose this method, consider adding an air freshener or fragrance to the towels for an additional smell.

What to Look for When Buying a Sploof

If you want to buy a manufactured smoke filter for your cannabis use, consider the following before buying any sploof:

  1. Materials Used: Choose an option made from smoke-safe materials while also looking for carbon filters and other components that ensure smoke and smell absorption. 
  2. Durability: DIY sploofs last one or two uses before getting dirty and germed up. Buying a sploof is guaranteed to last longer. Choose one that’s ideally easy to clean and sanitize. 
  3. Ease of Use: A sploof should never be confusing. If it takes more than a moment to figure out, it might be too complicated of a device for this job. 
  4. Trusted Sellers: Only buy sploofs from reputable online shops. Purchasing from the brand directly or through marketplaces that ensure product safety.
  5. User Reviews: Word-of-mouth reputation remains essential in the world of cannabis, much like the strain you’re smoking, getting feedback from other consumers is always helpful in making purchases.
