For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. [3] But higher-quality vacuums are possible. Ultra-high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth (10 −12 ) of atmospheric pressure (100 nPa), and can reach around 100 particles/cm 3 . [ 4 ]
