Airdog  TPA  Technology: Washable Solution

Do you know? HEPA is made of the same material as plastic bags. One HEPA filter euqals to at least 1000 plastic bags. Airdog washable air purifier, say NO to the wasteful HEPA filters! With our reusable, easy clean collecting plates, you will save time, money, and our planet with our energy-efficient and WASTE-FREE design.         

 Airdog’s patented TPA technology is an active filtration technology.

Airdog’s patented TPA technology is an active filtration technology. It generates a high voltage electric field to electrify and destroy harmful particles and collects them on the easy-to-wash collecting plates. Airdog ensures that clean air is the norm rather than a luxury. Its 3 layers of Washable Filters value equates to zero dollars in running cost while eliminating up to 99.9% of Harmful Particles, 99.9% of PM 2.5, and 99% of Chemical Toxins in the air it cleans. 

The air we breathe matters most - our health and wellbeing depends on it! According to the Centers for Disease Control, 1 in 13 people suffer from asthma and over 50 million Americans suffer from allergies each year. Airdog collaborated with a group of expert engineers in Silicon Valley to protect you from the dangerous particles that pollute our indoor air everyday and cause disease.

How TPA Works

How Airdog TPA Works


Vertical Airflow - Airdog TPA VS HEPA

Vertical Airflow

There is a reason for high performance.

General hepa filters will block the air flow. When the filters become clogged, the air flow will be significantly reduced! Airdog 's vertical absorption filter that does not interfere with the airflow. It will not cause clogging and does not reduce air flow,which contributes to higher filtration performance and lower noise. 

Filtration Range

TPA®️ Filters purify a much wider range than the traditional HEPA filter - from particles down to 0.0146 microns to PM 2.5 (cigarette, exhaust, dust, pet danders), and bigger particles (pollen, pet hair).

HEPA traps pollutants such as pollen and dust, while TPA technology destroys these toxins and eliminates them from our air. Often times HEPA air purifiers will stop working when the filter isn't changed regularly. Pollutants that were once collected can escape back into the air! Furthermore, when the temperature is warmer and humidity is in the air, mold and bacteria grows on the HEPA filter causing bad odors and hazardous waste generated during the process. Airdog's washable filter solves this problem by creating an easy clean system that is safe and effective. Just wash with detergent and reuse them!

There is a technical term called CCM (cumulative cleaning mass), which means how much pollutants a HEPA could trap before it lzoses 50% efficiency. For a typical HEPA air purifier, lab researchers have quantified 45 cigarettes smoke would make it fail. As a comparison, after 440 cigarettes, about 10x more than HEPA’s 45, Airdog’s cleaning capacity only drops – 0.2%! That means Airdog can take 10x more smoke and stay 50x stronger in cleaning capacity! Now that’s a Huge Difference!


Since mold and bacteria like to grow on HEPA filters, you need to change those very expensive filters every 6 months. Spending money on these replacement filters can easily cost $500 per year, and the better quality HEPA filters cost even more. Airdog solves that filter replacement problem with its advanced TPA technology and saves you money! No more need to change filters with Airdog…just wash them! This Saves You Lots of $$!

Environmentally Friendly

With the waste crisis on Earth, it is vital that we do our part to contribute to a better planet and a better future. HEPA filters are made of dangerous fiberglass material that is damaging to our environment. With Airdog, you don't need to replace the filters, just wash and reuse. No disposal of wasted filters helps to save our environment!

Whisper Quiet

You will hardly know it's there. Airdog's noise level range from 22dB (sleep mode) to 57dB (turbo mode) and average at 34dB which is half of traditional air purification systems. This is about as quiet as a soft hum, and definitely more quiet than your neighbors dog.
