accessories in a sealed box, to be opened only upon use.
The electrostatically pre-charged filter combines the normal mechanical filtering of the air that
passes through the filter, with an electrostatic attraction of powder that increases its filtering
considerably. The electrostatic pre-charge of the filter is spent after two years of the box being
opened, after this period it behaves like a normal filter.
