Ozone output/coverage claims are inconsistent across retailer SKUs sharing the 'O-777' name: one source cites 11,000mg/h with ~2,000 sq ft coverage; another (differently-specced) listing cites 60,000mg/h. Given this inconsistency, treat any specific number with caution and verify directly with the seller.
Not Applicable - this is a pure ozone generator with no HEPA filter of any grade

Includes True HEPA layer within its Tri-Power filter (99.97% capture rate) - but this is PECO-PRIMARY technology, not a HEPA-first design; independent reviewer notes CADR/particulate performance is 'lower' than dedicated HEPA competitors at similar price points
Not explicitly published as an exact dB figure for Air Pro specifically in this search pass (Air Mini+ range of 39-62dB found, should not be assumed identical for the larger Air Pro)

Rated for approximately 2,000 cubic feet (57 cubic meters) of space per treatment claim (note: this is a cubic-footage/volume rating, not the square-footage rating typically used by conventional purifiers - not directly comparable without knowing ceiling height)

Rated for 1,000-6,500 CFM airflow / 2.5-16.25 ton HVAC systems (compatible with the vast majority of residential and light-commercial central air systems - NOT a standalone square-footage rating like portable purifiers, since coverage = whatever the connected HVAC system serves)
Not Applicable - this device has NO HEPA filter of any kind; it works entirely via Advanced Oxidation Process (ionized hydro-peroxides, superoxide ions, hydroxide ions) distributed through the existing HVAC ductwork, not mechanical particulate filtration
Not explicitly published as a standalone dB figure in available sources - unit itself is silent (RGF's own materials note it 'operates silently'); any noise would come from the host HVAC blower, not this device
