Go Beyond HEPA with FDA-Cleared TPA® Technology

Standard air purifiers leave behind the smallest, most dangerous particles. Airdog air purifiers uses TPA® — a FDA cleared technology that goes far beyond HEPA — to deliver truly medical-grade air purification.

🦠0.0146um Ultrafine Particle Capture

Airdog captures particles down to 0.0146 microns -20x smaller thanwhat standard HEPA filters.

🛡️99.9% Germ Kill Rate

TPA® technology not only collects particles, but also actively destroys 99.9% of bacteria and viruses on contact.

💰$0/yr No Filter Replacements

Washable and reusable filters eliminate costly filter replacements and save $500+ over 5 years.

🔇22dB Quiet Operation

Low airflow resistance delivers quiet and efficient purification at just 22 dB in sleep Mode.

20x More Effective Than HEPA Filters

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.

Destroy. Not Just Trap

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 destroy 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.

Lifetime-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.

Don’t Just Take Our Word For It

Check out why people love Airdog

"I've struggled with allergic rhinitis for years. That an a deviated septum keep me from sleeping well at night. I was sure that poor indoor air quality in my house was compounding the problem.I'm sleeping much better at night and am having to take much less allergy medication. I even bought a second unit to put in the front of the house.

"I bought this as a Christmas gift for a friend from India. They use a lot of spices and the smell lingers for a long time. They had dinner then went out and when they came back the smell was completely gone. They were very impressed with the unit."

"For the first time in a while, the kids don't wake in the morning all coughs and sneezes. We are no longer taking any allergy medication. ... Thanks to the X8, we are finally dealing with the cause and not just our symptoms."

"This is the best air filter I've had. I'm in love with it. ... Due to cat dandruff, I have a hard time breathing. It is hard for me to sleep at night but since getting the X5, I am sleeping all night now and breathing through my nose again."

"My family is breathing so much better inside now—no more coughing, we sleep better at night, and even the pets seem to be more comfortable now."

"My LIFE depends on this Airdog X3. I am 75 years old and was told I have numerous allergies and would be needing a sleep apnea machine. ... I am allergy- and pill-free, no need for a sleep apnea machine, all my tests are perfect. Most of all, I BREATHE the MOST BEAUTIFUL FRESH AIR possible."

Frequently Asked Questions

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

Yes! Airdog TPA technology is designed to capture particles down to 14.6nm, including ultrafine airborne pollutants — up to 20X smaller than what traditional HEPA air purifiers are designed to capture.

Yes. Airdog purifiers are designed for modern homes with quiet operation, washable components, and smart air purification technology.

Airdog air purifiers are engineered with a built-in catalyst that actully helps reduce ozone to safe, near-zero levels — well below FDA, CARB, and EPA safety limits. In many indoor environments, ozone levels with Airdog can be even lower than typical outdoor levels. Designed for continuous 24/7 use, Airdog is safe for homes, offices, and everyday indoor spaces.

Traditional HEPA filters typically need replacement every 3-6 months and can actually make allergies worse if not changed regularly, as trapped allergens can become breeding grounds for bacteria and mold. Airdog's TPA® filters eliminate this concern entirely—they're completely washable and reusable for the life of the unit. Simply rinse them with water every few weeks, and they'll continue capturing allergens at peak efficiency without any replacement costs.
