Why Washable Air Purifier?

Traditional air purifiers rely on disposable filters that need frequent replacement, driving ongoing cost and waste. Airdog’s TPA® technology breaks this cycle with a washable system.

🚫No Replacement Filters

No disposable filter replacements, reducing ongoing maintenance cycles.

💰Lower Long-Term Cost

Reduce recurring filter expenses compared to conventional air purifiers.

📈 Consistent Performance

Maintains stable performance over time without efficiency loss from clogged filters.

♻️ Eco-Friendly Design

Reduces disposable filter waste by moving away from single-use filtration systems.

Key Benefits of TPA® Technology

Airdog’s patented Two-pole Active Filtration Technology® (TPA) generates a high-voltage electrostatic field that helps neutralize bacteria and viruses while capturing ultrafine particles as small as 0.0146 microns on washable, reusable collecting plates.

Beyond HEPA-Level Filtration

Traditional HEPA filters stop at 0.3 microns. Airdog’s patented TPA® technology goes 20× deeper—actively destroying ultra-fine toxins, smoke, and dander down to $0.0146 microns. It’s not just filtration. It’s
next-generation air purification.

Capture and Destroy

Traditional HEPA filters trap particles in dense filter media that can accumulate pollutants over time. Airdog TPA® technolog uses a high-voltage electrostatic field to capture and neutralize airborne particles on washable collecting plates.

Wash. Reuse. Save

Say goodbye to costly filter replacements. Unlike traditional HEPA purifiers, Airdog’s TPA® technology uses washable filters that can be cleaned and reused—saving you money while reducing disposable waste.

Long-Lasting Performance

Unlike traditional HEPA filters that lose efficiency as pollutants accumulate, Airdog’s TPA® technology maintains long-lasting performance. After exposure to 440 cigarettes’ worth of smoke, Airdog’s cleaning capacity dropped by only 0.2%, delivering more consistent purification over time.

Frequently Asked Questions

What makes Airdog different from traditional HEPA purifiers?

Airdog uses advanced TPA® technology to actively charge and capture ultrafine particles, while traditional HEPA filters rely on passive filtration and require frequent replacements.

Are all the filters cleanable or do they need replacement?

All the filters of our air purifiers are cleanable rather than needing replacement. The collecting plates and pre- filter are washable with water. The wire frame filter is cleaned with a dry soft rag or felt-like cleaner, and the catalyst filter can be cleaned using a light vacuum and sunlight for refreshing. However, the catalyst filter may need replacement sooner depending on the environment and usage rate.

What size particles can TPA® capture?

TPA® technology captures a wide range of airborne particles, including ultrafine particles as small as 0.0146 microns, as well as PM2.5, dust, pollen, and pet dander.

Which Airdog model is right for my space?

It depends on your room size and needs. X3 is ideal for bedrooms and personal spaces, X5 is great for everyday home use, and X8 is designed for larger rooms and open spaces. P50 is built for pet-friendly homes.
