TPA Technology – 0.0146μm Filtration

Patented Two-Pole Active technology destroys particles rather than just collecting them. Filters 99.9% of particles down to 0.0146μm — capturing viruses, bacteria, and ultrafine PM2.5 that HEPA misses.

Lifetime Washable Graphene Filter

The durable graphene TPA filter washes clean with water and is fully reusable. No replacement filters to buy — ever. Saves hundreds of dollars over the lifetime of the purifier.

1614 Ft² Coverage

360° air circulation with CADR of 200 CFM/340m³/h. Completely purifies a 1614 ft² room once per hour, or a 404 ft² room 4 times per hour for intensive purification.

Real-Time Air Quality Monitor

Built-in AQI sensor displays real-time air quality via color-coded indicator light. Auto Mode automatically adjusts fan speed based on detected air quality for optimal efficiency.

22dB Whisper-Quiet Sleep Mode

At 22dB in Sleep Mode, the X5 is quieter than a whisper. Purifies your bedroom all night without disturbing your sleep — just set it and forget it.

Removes Pet Hair, Allergens & Odors

Effectively captures pet dander, hair, dust, pollen, smoke, and odors. Ideal for pet owners, allergy sufferers, and anyone in wildfire smoke or high-pollution areas.

Q: How is TPA different from HEPA?

A: HEPA filters physically trap particles down to 0.3μm. TPA technology uses a high-voltage ion field to actively destroy particles down to 0.0146μm — including viruses and ultrafine particles that HEPA cannot capture.

Q: How do I clean the washable filter?

A: Simply remove the graphene filter and rinse it under running water. Allow it to dry completely before reinstalling. Cleaning frequency depends on usage and air quality — typically every 2–4 weeks.

Q: Does it produce ozone?

A: The Airdog X5 produces trace amounts of ozone as a byproduct of the ionization process, well within safe limits set by regulatory standards. It is not an ozone generator and is safe for home use.

Q: What room size is it best suited for?

A: Ideal for large open-plan living rooms, master bedrooms, and open offices up to 1614 ft². For smaller rooms (under 400 ft²), it will purify the air 4 times per hour for intensive air quality control.

Q: How loud is it on the highest setting?

A: Maximum noise level is 46dB on the highest speed setting — comparable to a quiet conversation. Sleep Mode operates at just 22dB, quieter than a whisper.

Q: Is it good for wildfire smoke?

A: Yes. The TPA technology is highly effective at capturing fine smoke particles and PM2.5 from wildfire smoke, which are smaller than what standard HEPA filters can reliably capture.

⭐⭐⭐⭐⭐ — Michael B.

"I have two dogs and the air quality in my house was terrible. The X5 transformed it completely. The AQI monitor went from red to green within an hour. The washable filter means I’ll never buy replacement filters again."

⭐⭐⭐⭐⭐ — Susan L.

"My daughter has severe allergies and this purifier has been life-changing. Sleep mode is genuinely silent — I can’t hear it at all from across the room. The auto mode is smart and responsive."

⭐⭐⭐⭐⭐ — David K.

"During wildfire season our air quality was terrible. The X5 kept our living room clean even when the AQI outside was 200+. The TPA technology clearly outperforms the HEPA purifier we had before."
