Airdog takes air purification to the next level. So what, exactly, is this TPA technology? TPA stands for Two-Pole Active. Unlike HEPA — which just filters — TPA destroys particles. The technology uses charged ions to destroy bacteria and germs. It can capture even those tiny particles that might cause allergic reactions, such as asthma.



Airdog is the world’s first washable air purifier that alleviates all your air quality problems with just one touch of a button. Airdog’s washable filters alleviate the inconvenience of constantly purchasing new filters, which are small pieces of hazardous waste in themselves. The filter technology in Airdog leaves you with clean, fresh air without the need to buy or replace costly filters.

Bacteria grows on HEPA filters when the weather is warm, causing bad odors and hazardous waste in the air. Airdog’s washable filter is built to give you an easy to clean system that is safe and effective. Just wash your filter with detergent, dry it, and reuse it over and over again. This means that consumers can spend less time worrying about their filters, saving them time and money while offering a greener product that is safe for the environment.

Airdog’s patented TPA (Two-Pole Active) air filtration technology is a true innovation in air purification, and it’s award-winning too. It’s been used across 50+ countries and regions, and is ranked number one by healthcare workers. A Japanese independent third party survey gave it the best rating for air purification/sanitization solutions.
