The 1701 has a 5-Stage Filtering system with HEPA and NCCO filters Particles to 2.5 microns - Smoke, Dust, Dander, Mold.  

• CCO 5 Stage Filtration: Air is purified through a five-stage medical-grade filtration process including a pre-filter, static filter, active oxygen generator, a HEPA filter and finally an NCCO reactor. HEPA filter captures particulates (PM2.5), mold, bacteria and viruses. The NCCO Oxidation effect of active oxygen destroys and Kills the structure of bacteria and viruses to achieve thorough disinfection.
• The NCCO reactor filter can regenerate itself giving it a life-time use of up to 12yrs. When time comes to dispose, it can be done safely with no harm to the environment, unlike other air filtration technologies.
• Combat Harmful Allergens: The 1701 tackles harmful allergens up to 2.5PM, including smoke, pet dander, dust and mold and deodorizes in the process.
