Used SMARTCORE STICKS™ have two indicators that tell you if they’ve been used. The paper around the filter is slightly creased, and there will be a slight aerosol stain on the paper. We recommend you dispose of the stick immediately after use to avoid any confusion. Another way to avoid reusing a stick is by placing it back in the pack upside-down. When you select your stick check that the mark is visible on the filter.
