TPA® TECHNOLOGY

More >>
Unlike conventional HEPA filters that require frequent replacement, Airdog’s patented TPA® technology captures ultra-fine particles and allows filters to be washed and reused.
 
----------------------------------->>>   Ultra-Catalytic Filter
The final step in the purification process removes unpleasant odors, keeping your air fresh and pure.
 
----------------------------------->>>   Washable Collecting Plate
Charged particles stick to the collecting plates, removing dangerous toxins from the air.
----------------------------------->>>   Super Ionic Field Zone
Annihilates bacteria and germs. Charged particles are destroyed.
----------------------------------->>>   Wire Frame
Creates an Electro Field that zaps dangerous particles that would be traveling into our lungs.
----------------------------------->>>   Primary Filter
Air flows from the bottom and into the Pre-Filter to collect hair, pet dander, etc.
 
Remove and kill viruses & bacteria, fungus, hair, pet fur, mould, allergens, dander, pollen, spores, smoke, dust, mites, odors, formaldehyde, PM2.5, TVOCs, germs, etc.

However, there are also many hidden issues, such as the filter needing to be replaced 2 to 4 times a year, and the cost of filter replacement is high. Filter blockage reduces the purification efficiency. Therefore, we recommend the new TPA technology air purifier.
