Are your neighbors finding out about your cannabis use? Your parents too? They are worried about your smell of weed? Below, you will discover a cheap and easy way to filter out the smell of cannabis: the homeade sploof!

What is a sploof?

The characteristic smell of cannabis is a double-edged sword. On the one hand, the aromatic terpenes that underlie this smell delight the olfactory system and give each strain its unique flavor and effect. On the other hand, these pungent molecules alert everyone within 328.084 feet- 100-meter – radius outdoors and in every other room of the house that you are consuming weed.

No other plant smells as strong as cannabis. To conceal their activities, smokers for decades have used their ingenuity to develop a do-it-yourself device that eliminates cannabis odors quite well: the Sploof.

Sploofs are filters that trap terpenes. When cannabis smoke is exhaled through a sploof after smoking a pipe or bong, a good amount of these molecules are absorbed, meaning less smelly smoke comes out the other end. As the cannabis industry flourishes, more and more companies are offering commercial sploofs that use replaceable filter systems and environmentally friendly cartridges to capture and mask odor.

However, sploofs are nothing new. They began as simple devices made from toilet paper rolls, rubber bands, and paper towels, developed largely by teenagers trying to hide the smell of marijuana in their parents’ home.

What is the lifespan of a sploof?

After assembling a Sploof, you can expect all the individual pieces to last at least 2-3 smoking sessions. After that, the filter will become saturated, smelly, and less effective. However, the other major components will last much longer. The body of a sploof, usually made from a cardboard tube or plastic bottle, will last for weeks or months, as will the elastic band that holds the filter to the body.

Fortunately, filters are often made from paper towels or dryer sheets, so they can be easily and very cheaply replaced on a regular basis. A single sploof will last for weeks, as long as the filter is changed regularly.

What you need to make a homemade sploof

Homemade sploofs are fairly simple: you only need a few household products and a few minutes of time to make them. Before you start making them, you’ll need to get the following things:

• Toilet paper tube/plastic bottle (preferably one with a wide opening).
• Unscented dry paper or wipes that are not wet.
• Elastic band
• Scissors
• Activated charcoal (for the second method)

How to make a homemade sploof with dryer sheets: step by step

1. If you are using a plastic bottle, cut off the bottom.

2. Fill the tube or bottle with about 5 wipes. Don’t compact them too tightly, as the smoke must be able to pass through all the sheets.

3. Put a wipe over one end of the toilet paper tube or plastic bottle. Make sure it is taut and secure it with a rubber band.

4. Use a pair of scissors to cut off the excess towelette that hangs outside the rubber band to make it fit snugly.

5. Now you can use your sploof and smoke indoors without any problems!

How to make a charcoal sploof

When using activated charcoal, the process is slightly different. Firstly, for this method, it is better to use a plastic bottle instead of a toilet paper tube. Secondly, you will need activated charcoal, which you can find in pet stores or on the Internet.

• Activate the charcoal by soaking it in water.
• Make 5 to 10 holes in the bottom of the bottle.
• Fill the bottle with activated charcoal. You can wrap it in a damp paper towel or not; the choice is yours!

How to make a sploof without wipe blades: Step by step

• Use sharp scissors to make several holes in the bottom of your plastic bottle.
• Cover the bottom end of the bottle with 2 or 3 sheets of paper towel and secure them with a rubber band.
• Trim the excess paper towel hanging outside the rubber band grip for a more uniform look.
• Unscrew the cap of the bottle; we recommend using a wide-mouth bottle if possible, as this will prevent smoke from spilling out and entering the air unfiltered.
• Apply a spray of air freshener in the air between puffs to compensate for the lack of activated charcoal.

Does the homemade sploof really work?

Sploofs are effective, but not flawless. But what they lack in effectiveness, they make up for in cost-effectiveness and simplicity. You can make a homemade sploof yourself with everyday household materials in just a few minutes. The effectiveness of a sploof also depends on the material used.

The method using activated carbon is the most effective and the most durable. However, it’s also the most expensive and complex. The other options will not filter the smoke as well but are an inexpensive alternative.
