, meant to seize large particles just before they get to the first filter; this aspect can cut functioning expenditures by extending the life of the leading interior filter.
The tools: Given that 2016, we’ve executed dozens of authentic-earth purifier exams, measuring particle concentrations with a TSI AeroTrak 9306—knowledgeable, higher-precision particle counter normally accustomed to certify air quality to OSHA specifications in factories and also other workplaces.

If a purifier does effectively on smoke, it will eventually do better still on larger particles like dust and pollen, and—relatively paradoxically—on smaller particles like bacteria and viruses. For a proof, see How HEPA filters function.
