12 LAYERS. THREE STAGES.
How It Works
Stage 01 — Insert
Slide the Tarducer™ into your Tarcut™ holder. 7.8mm precision bore. Tool-free press-fit. Scroll-snap opens one-handed — the flat rectangular mouthpiece seats flush in under 2 seconds.
Stage 02 — Draw
12 layers engage in sequence across 6 filtration mechanisms — mechanical, chemical, ion exchange, electrostatic, moisture regulation, and Coanda reflux. Coconut-shell activated carbon (800 mesh), HEPA nanofiber membrane (0.3μm), and ion exchange resin work simultaneously. <15% draw resistance increase.
Stage 03 — Replace
The inspection window turns amber as the Tarducer™ reaches capacity — no app, no timer. Amber means done. Twist, swap, press. The ritual continues.
THE PROOF YOU CAN SEE
0.47g. That's what stayed out.
We put a fresh Tarducer™ on a precision scale. 3.42 grams. We smoked 20 cigarettes through it. We weighed it again. 3.89 grams. That 0.47-gram difference is tar, particulate, heavy metal condensate, and volatile organic residue — trapped across 12 layers before it reached the mouthpiece. You can see it in the window. You can measure it on a scale.
Fresh — 3.42g — clear window
After 20 cigarettes — 3.89g — 0.47g captured
INSIDE EVERY TARDUCER™
12-Layer Sequential Filtration
Sealing O-Ring + Ceramic Pre-Filter
L1 medical-grade silicone O-ring — airtight fit, zero bypass. L2 sintered ceramic disc — blocks ash and coarse debris before the filtration core.
Silicon Crystal Bed + Activated Carbon
L3 silicon crystal granules — moisture regulation, stabilises the smoke stream. L4 coconut-shell activated carbon, 800 mesh — same material as military gas masks. Broad-spectrum chemical adsorption of VOCs and tar.
Fiber Filters + Ion Exchange Resin
L5 green fiber — melt-blown microfiber, PM2.5 capture via electrostatic attraction. L6 ion exchange resin — selectively binds cadmium, lead, arsenic. L7 white fiber — intermediate tar and nicotine interception.
Nano Minerals + HEPA Nanofiber
L8 tourmaline-zeolite nano crystals — molecular sieve, captures benzene and VOCs from the gas phase. L9 purple fiber — high-density, final heavy tar capture. L10 HEPA nanofiber membrane — 0.3μm, 99.5% capture. Cleanroom standard.
Coanda Reflux Chamber + Mouthpiece
L11 Coanda-effect recirculation — forces smoke into secondary wall-contact circulation. More dwell time. Transparent inspection window turns amber when done. L12 hardened resin mouthpiece — ergonomic, heat-isolated.
INDEPENDENT TESTING — 6 FILTRATION MECHANISMS
RATUM° makes no medical or health benefit claims. Tarducer™ is a precision filtration accessory, not a medical device or smoking cessation product. Performance specifications are engineering targets; third-party lab certification pending. Weight measurements from controlled testing — individual results vary by cigarette brand and smoking pattern.

FAQs
Fits all standard 7.8–8.0mm cigarettes — Regular, King Size, 100s, 120s. Brands include Marlboro, Camel, Newport, Parliament, American Spirit, and most worldwide. Not compatible with Slim or Super Slim.
~20 cigarettes. The inspection window turns from clear to amber as the cartridge works — amber means replace. Fresh weight 3.42g → used ~3.89g (0.47g captured). No app. No timer.
Yes. The Tarcut Starter Kit ($29.90) includes the CNC-machined aluminum holder + 3 Tarducer cartridges. The holder is permanent — only cartridges are replaced.
Draw resistance increase <15% by engineering spec. Triple-channel airflow and the Coanda-effect reflux chamber prevent the bottleneck of single-channel filters.
The transparent inspection window turns amber as filtration capacity is consumed. Amber = replace. The window is built into the cartridge — no app, no guessing.
No. Each Tarducer™ is a single-use 12-layer unit. Reusing degrades all layers and breaks the airtight silicone O-ring seal. The cartridge body is recyclable PETG.
