The machine performs 5 air changes per hour – calculated with a ceiling height of 2.4 m and an H13 HEPA filter – filtering up to 99.95% of 0.1 micron particles from the air, including allergens such as pollen, dust, and pet hair. It eliminates odors – the pre-filter removes larger particles and contaminants and increases the performance of the other filters, while the carbon filter actively removes odors and volatile organic compounds.
