After two years of buying HEPA filters every few months, I switched to the X5. My PM2.5 readings dropped from the 40s to under 5 within an hour. The plates are easy to wash and honestly kind of satisfying.

AQI outside hit 187. Inside with the X5 running: single digits. It ran on auto the whole time and I didn't touch it once. No filter to replace mid-emergency.

I use a separate air-quality sensor and it confirms everything. The air improves quickly, the purifier stays quiet, and the washable collection plates are simple to maintain.

The technology gap
While traditional air purifiers use HEPA filters to trap pollutants, Airdog utilizes patented Two-Pole Active (TPA) technology. This system creates an electrical charge that destroys harmful particles instead of just trapping them.
Airdog purifiers have been proven to capture and destroy particles down to 0.0146 microns. Traditional HEPA filters are only tested to capture particles down to 0.3 microns.

Every other air purifier company requires replacement filters. By year two, an Airdog purifier costs less than a HEPA-based purifier—and you'll keep paying for the entire life of the machine.
