The AC-9966 features Ionizer and a Four-Stage filter assembly: Pre-Filter (PP Mesh Filter), cutting-edge Plasma Technology (Tungsten Filament + Grounding Net), VOC filter and HEPA filter. Targeted to effectively remove smoke1, dust1, pollen1, PM2.51, bacteria2, mold2 and virus3 in a 1,000 cu.ft. space. Both HEPA and VOC filters are designed to operate continuously for up to 3,000 hours.

What is CADR? (Clean Air Delivery Rate)? The CADR indicates volume of filtered air delivered by an air cleaner. The higher the smoke, pollen and dust numbers, the faster the unit filters the air. https://en.wikipedia.org/wiki/Clean_air_delivery_rate

Ionizer: removes 99.97% of positively charged dust particles, pollen and small allergens.

PP Mesh Pre-Filter: traps larger air pollutants such as dust and dander.

Plasma Technology (Tungsten Filament + Grounding Net): Effectively inactivates airborne bacteria and virus, making the air that passes through healthier to breathe. Front protection net installed with high voltage Tungsten (ionization) filaments (+4kv) are the components to generate plasma through constant corona discharge. The back cover (grounding net) carries negative high voltage (-7kv) and serves as a guidance of the electrons movement and helps enlarge the electric field. This creates enough positive electricity in the field to speeds up free electrons. Energy created can ionize and separate gas molecules or atom electrons. In addition, positive corona generates much less ozone than negative corona.

VOC (Formaldehyde) Filter: Formaldehyde and other VOCs can be found in building materials, foam insulation, household products and fuel-burning appliances. They can prompt headaches, vomiting, rashes, asthma attacks and some are suspected to cause cancer. AC-2102 VOC honeycomb filter has 8.5oz of modified Activated Carbon impregnated with 8.5oz of Zeolite particles. Effectively removes formaldehyde, toluene and VOC. Factory tested: VOC removal efficiency reaches 95%, under the following conditions: 1m³ test room; initial concentration: 1.9-2mg/m³; 4hrs testing.

HEPA Filter: A high-efficiency air filter that captures 99.5% of airborne pollutant particles as small as 0.3 microns, including spores, pollen, mold, pet dander and dust.
