High-Efficiency 5-Stage Filtration: Our HEPA air scrubber is equipped with a MERV-10 filter to capture large particles and a HEPA-grade MERV-17 filter. This dual filtration system achieves an outstanding 99.97% efficiency at 0.3 microns, effectively addressing challenges like concrete dust, fine sand dust, or gypsum dust. Advanced Light and Ionizer Technology: The commercial air scrubber features built-in light technology and an ion generator (Ionizer with the highest output of up to 30 Million Negative Ions per Second). These components work in conjunction with HEPA filters to efficiently reduce tough odor molecules before reaching the filters. Ideal for spaces up to 800 square feet.
