Highlights
- Activated carbon filtration: Catches the bulk of smoke particulates and odor compounds before they reach the room — the difference between an obvious session and a discreet one.
- ~200 exhales per filter: One Houdini covers weeks of personal use before you need to replace it (heavier or wetter sessions will shorten that).
- Pocketable 3.6" body: Slim and light enough to carry in a jacket, bag, or alongside your rig — no bulky bottle or DIY dryer-sheet tube.
- Disposable, no maintenance: No filters to wash, refill, or reload. When it's done, you toss it and start fresh.
- Works for smoke and vapor: Designed around cannabis combustion, but equally effective for dry-herb and concentrate vapor.
- Four finishes: Pick the bio-based plastic for a more sustainable option, or the Cactus, Blush, or Onyx colorways to match your kit.
In the Box
- 1x MJ Arsenal Houdini smoke filter: Disposable carbon-filtration sploof in your selected finish, ready to use out of the package.
Description
The MJ Arsenal Houdini is a disposable carbon-filtration smoke filter — sometimes called a sploof — that captures airborne particulates and odors from each exhale. Designed for discreet use in apartments, offices, dorms, and other shared spaces, it's a pocketable accessory from MJ Arsenal that lets you smoke or vape without leaving a lingering smell behind.
The Houdini's compact 3.6" body holds activated carbon and a smoke-reclamation chamber. Exhale through the mouthpiece and the filter traps the visible smoke and most of the scent, releasing nearly clear, near-odorless air. Each filter is rated for roughly 200 exhales — performance varies with usage and material — and once it's spent, you replace it. It's available in four finishes (Biodegradable Plastic, Cactus, Blush, Onyx) so you can match it to your stash gear.
FAQs
- Does the Houdini eliminate all smell? It captures the bulk of the visible smoke and most of the odor, but it isn't 100%. Strong sessions or back-to-back hits will still produce some residual smell — pair it with our smoke odor spray for the best result.
- How many exhales does one filter handle? Roughly 200, per MJ Arsenal. Heavier hits, dab vapor, and humid environments will shorten that window.
- Can I use it with a vaporizer? Yes. It works with dry-herb vapor, concentrate vapor, and combustion smoke. Vapor sessions tend to extend filter life because there's less particulate.
- Is it reusable? No — the Houdini is a single-use disposable. When exhales start passing through more visibly, swap to a new one.
- Does it work for cigarette or cigar smoke? It's designed for cannabis smoke and vapor. Tobacco smoke contains tars that clog carbon faster, so expect significantly reduced filter life.
- What's the difference between the four finishes? All four use the same internal carbon and reclamation system. The Biodegradable Plastic version uses a bio-based shell; Cactus, Blush, and Onyx are colorways of the standard plastic body.
- How do I dispose of a spent filter? Treat it like household waste. The Biodegradable Plastic version is designed to break down faster than conventional plastic in commercial composting conditions.

- What a sploof does: A sploof is a small filter you exhale through. Activated carbon inside the device traps the odorous compounds and visible smoke before they reach the room.
- Why people use one: If you can't crack a window or you live with people who don't want to smell smoke, a personal filter is the easiest way to keep your sessions discreet.
- How to use it: Inhale your hit normally, then exhale fully through the Houdini's mouthpiece. Don't inhale through it — it's a one-way device.
- How to know when to replace it: When you start seeing visible smoke pass through the exhaust end, or when the device starts smelling stale, the carbon is saturated and the filter is done.
- Where it fits in your kit: It pairs naturally with any portable rig, dry-herb vape, or pipe. For more odor-management options, browse our odor control accessories.
