Activated carbon is a highly porous material that can absorb volatile chemicals on a molecular basis, but does not remove larger particles. It is normally used in conjunction with other filter technology, especially with HEPA. Air cleaners that do not feature at least 15 lb (7 kg) of carbon can not efficiently remove VOCs, chemicals, and strong odors from the air[citation needed]. Other materials also can absorb chemicals, but at higher cost.
