The smell fades first

Why the usual fixes don't clear the air

Opening windows

Opening a window thins the smell, but it can’t clear the smoke from a room on its own.

Smoking on the balcony

Smoke can drift back in through door gaps, vents and open windows.

Waiting for the smell to fade

Your nose gets used to the smell, so it isn’t a reliable sign the air is clear.

Third-hand smoke

Smoke residue doesn't vanish. It waits.

It clings to sofas, carpets and walls for months, and some of it can drift back into the air. Kids and pets spend the most time close to those surfaces.

Run Airdog on Auto to keep capturing particles that drift back into the air. It can't clean surfaces, so keep washing fabrics and wiping walls too.

“Very powerful x5, no smoke smell even if you smoke in the room”

How TPA® works

See how Airdog captures smoke

HEPA filters are tested at 0.3 μm, the size they find hardest to catch. In lab testing, TPA® captured particles down to 0.0146 μm.*

  1. 01

    Charge

    A high-voltage wire frame gives passing smoke particles an electric charge.

  2. 02

    Collect

    An ionic field pulls the charged particles onto the plates, down to 0.0146 μm in lab testing.*

  3. 03

    Rinse

    Washable plates hold the residue until you rinse them clean.

  4. 04

    Deodorize

    The catalyst filter handles odor. In lab testing, Airdog cut smoke odor compounds 93%.* Replace the filter every 1–2 years.

Rinse the plates. Skip the HEPA refills.

Slide out the plates, wash off the residue, let them dry and slide them back in. Clean plates keep airflow strong. The carbon filter is the one part you replace, every 1–2 years.

*Third-party laboratory testing of the Airdog X5s: 99% of cigarette-smoke PM2.5 removed in a 30 m³ chamber in 27 minutes; 93% reduction in cigarette-smoke odor compounds (ammonia, acetaldehyde, acetic acid) in a 1 m³ chamber in 30 minutes (JEM 1467); TPA® particle capture to 0.0146 μm. HEPA filters are rated to capture 99.97% of particles at 0.3 μm. Real-world performance varies by room size, airflow and conditions. Airdog reduces smoke particles and odor in the air. It does not remove residue from surfaces or protect against the health effects of smoking or secondhand smoke.

**Estimate based on typical HEPA replacement filters at $50 to $150 every 3–6 months.
