The secret behind powerful filtration

Our unique combination of electrostatic and mechanical filtration that we call HEPASilent™ filtration technology sets us apart. The combination allows us to use filters that are less dense and require less air pressure than traditional HEPA filters without a loss in performance— resulting in quieter and more energy efficient air purifiers.
