This innovative 7-stage filtration system is designed to capture even finest particles while anti-bacterial and deodorant effects work to clean exhaust air.
This is a cutting-edge technology that uses a TiO2 catalyst to provide powerful deodorizing effect. Nano Titanium particles are incredibly small (about 5 nm). Filter of Hitachi vacuum cleaners are packed with these minute particles to firmly catch and resolve odors.

Direct, high-power suction assures maximum efficiency. And centrifugal airflow creates a tornado effect that prevents even small dust particles escaping.
Dust compression technology works compressing dust by 50%. Even if capacity of a dust case is 1.6 L, it can hold 3.2 L of dust.
With easy one-touch operation your hands stay clean even after dust removal. As dust is compressed, it can be removed with minimal dust flying.
