Air Filtration-Vacuum Cleaners

Some vacuum cleaners give air filters, which can filter even the tiniest particles of dirt. These filtration systems collect particles from the air drawn into the machine without allowing them to be redistributed back into the air via the vacuums exhaust. Filtration systems can have many layers made of paper, nylon, cloth or foam. An air filter is a boon especially if you are allergic to dust.
