Clean air is the other invisible foundation. We're testing purifiers against real-world pollutants, not marketing specs.
Indoor air can be 2-5x more polluted than outdoor air. Air purifier marketing emphasizes CADR numbers tested in ideal conditions, not real-world performance against VOCs, particulates, and biological contaminants. We're building independent performance profiles using standardized testing.
Particulate removal
PM2.5 and PM10 filtration efficiency at various fan speeds
VOC reduction
Formaldehyde, benzene, and other volatile organic compound removal
Ozone emissions
Does the purifier itself produce harmful ozone as a byproduct?
Filter longevity
Real-world filter replacement intervals vs manufacturer claims
Noise levels
Measured decibels at each fan speed in standardized conditions
Energy consumption
Power draw per CADR unit for efficiency comparison
