SHIPPING: We have warehouses in USA, UK and Asia. Orders to North America and Europe are packed same day if ordered before 3pm, or next day if order is received after 3pm. The masks then arrive within 2-4 working days, depending on location.
BASIC vs PRO: We offer 2 ranges of mask. The PRO uses military grade filters developed for chemical, nuclear and biological warfare protection. They filter nearly 100% of viruses, bacteria, gas pollution and particulates. The BASIC has a fantastic particulate filter to remove pollution such as PM2.5 and dust but they have no carbon, so are less effective with viruses and bacteria and will not filter gasses.
