HEPA vacuum filters are the standard method used by the top vacuum cleaner manufactures use to remove dust, allergens, dust and mold from vacuum cleaner exhaust air. HEPA stands for High Efficiency Particulate Arresting" filter. HEPA filters were design during the Second World War to filter out nuclear dust and particles during nuclear weapons research and production.

HEPA vacuums also do an excellent of cleaning your house. There is little of no difference between the suction power of HEPA vacuums and vacuums with ordinary filters. Some manufactures have even designed HEPA filtration system for vacuum cleaners that use an older design throw away bag.
