Powered by Airdog. The AirSoap X8 is built on Airdog's TPA filtration and carries Airdog branding on the unit and its packaging. AirSoap X8 is the whole-floor version of the filterless purifier — 470 CFM of clean-air delivery, enough for up to 4,000 sq ft at one air change per hour. TPA (Two-Pole Active) filtration doesn't trap particles the way a HEPA filter does; it charges each particle and destroys it in an ionic field, then collects the remains on washable, reusable plates. All five stages wash, so there are no replacement filters to buy and no drop-off in airflow as media clogs. TPA captures down to 0.0146 microns, roughly 20 times finer than HEPA's practical floor, which covers smoke, pollen, dander, mold spores, and dust. Five fan speeds plus CADR, Sleep and Auto modes, running from 39 dB. A wireless AQI detector is included, so Auto responds to the air where you actually are rather than at the unit. 470 CFM CADR — 1,000 sq ft cleaned in about 15 minutes Up to 4,000 sq ft coverage; 1,000–1,330 sq ft recommended for 3–4 air changes per hour Five-stage washable TPA filtration — no replacement filters, ever Wireless AQI detector included in the box From 39 dB · 110 W · FDA Cleared, CARB, Energy Star Ships in Airdog packaging. This unit is manufactured by Airdog and arrives in an Airdog-branded box with Airdog documentation — not AirSoap packaging. It is the same air purifier described on this page, sold and supported by PhoneSoap.
