    Purification Level and Type of Filter

    The Blueair 7470i Air Purifier flaunts an extremely advanced filtration system that combines both electrostatic and mechanical technologies to ensure that you enjoy a crispy clean environment 24/7. It also adopts a three-stage filtration process to ensure the optimal elimination of 99.97% of airborne pollutants, including bad odors and toxic gases.

    GermShield Technology

    We love the GermShield Technology that monitors your indoor air for bacteria and common viruses; it subsequently employs a low air draft and plasma charging technique to kill the airborne contaminants. Besides, this function introduces a gentle stream of air to prevent the growth of new germs and bacteria. In the long run, this feature ensures that you enjoy an environment that’s free of allergens and disease-causing organisms.


    The first stage of protection against airborne pollutants is the patented preliminary filter that traps large and visible pollutants like hair, lint, fur, and dust. This unit comes with two pre-filters, which implies a wide filtration surface to ensure that no large particles go into the unit. These filters also protect the HEPA filter from clogging up and damage and thus prolonging its lifespan.

    HEPASilent Ultra Filter

    This is the second stage of filtration. It utilizes similar technology as the true HEPA filter but features germ-killing properties. This filter traps 99.97% of airborne pollutants as small as 0.01 microns and kills 99% of these contaminants to ensure that they are not re-introduced into your indoor environment.

    Activated Carbon

    This filtration stage is tasked with eliminating VOCs, smoke, and bad odors. It works by absorbing the gases and trapping them to ensure that they are not reintroduced into your room’s atmosphere.

    Our highlight: This unit comes with two individual pre-filters. The activated carbon filter is attached to the HEPA filter.
