Whether you’re living in a shared apartment, chilling in a college dorm, or traveling on the low, smoking weed indoors can be risky — not because of the smoke itself, but because of the lingering, loud odor that gives it all away.
That’s where smoke filters and personal air devices (aka sploofs) come in. These small but mighty tools trap exhaled smoke and smell, turning an obvious cloud into a whisper of clean air.
In this guide, you’ll find the top-rated sploofs and smoke filters available on Amazon, plus real comparisons between homemade vs. commercial devices. Because sometimes, toilet paper tubes and dryer sheets just don’t cut it anymore.
What Is a Sploof (and Why Do You Need One)?
A sploof is a device that filters and deodorizes the smoke you exhale, so it doesn’t stink up your space. You blow your hit through the device, and it releases filtered air that smells neutral or faintly clean, instead of cannabis.
Ideal For:
-
Apartment renters trying to avoid deposit loss
-
Students living under “no smoking” rules
-
Smokers who live with family
-
On-the-go users who want to keep things low-key
How Smoke Filters Work
Most commercial sploofs use a combination of activated carbon and HEPA-like material to trap odor molecules and smoke particles. Some include:
-
Foam layers to reduce heat
-
Charcoal granules to bind odor molecules
-
Silicone mouthpieces for easy, airtight use
-
Replaceable filters or long-lasting cartridges

-
Homemade Sploof vs. Commercial Filter: Worth It?
Homemade Sploof
Usually made with:
-
Toilet paper roll or plastic bottle
-
Dryer sheets
-
Rubber bands
Pros:
✅ Practically free
✅ Easy to DIY
Cons:
Doesn’t eliminate smell — just masks it
Dryer sheets = synthetic chemicals in your lungs
Messy and inconsistent
Doesn’t last more than a few sessions
Commercial Smoke Filter
Usually includes:
-
Sealed carbon chambers
-
HEPA-style filtration
-
Airtight casing
Pros:
✅ Actually removes odor, doesn’t mask
✅ Long-lasting and reliable
✅ Safe materials
✅ Easy to use anytime
Cons:
Slight upfront cost ($15–$35)
Needs occasional maintenance or replacement
Bottom Line: Homemade sploofs are fine in a pinch — but if you smoke regularly, a commercial filter is cleaner, safer, and way more effective.

FAQ: Common Sploof Questions
Q: Will these work for joints or only vapes?
A: They work for all exhaled smoke. Just exhale fully into the filter after your hit — vape, bong, joint, whatever.
Q: Can I wash a Smoke Buddy?
A: No. These are not washable. Once the filter is spent, replace it.
Q: Will it work in a room with no window?
A: It helps a lot, but add an air purifier or carbon bag for best results.
Q: Can I take a sploof on a plane?
A: Yes — it’s legal and odor-free. But don’t use it mid-flight. Store in checked or carry-on bags.
