China Filter Press

When it comes to vacuum cleaners the two main types of upright vacuums  are vacuum cleaners that use bags and vacuum cleaners that don't.  These two types of vacuums work on the same principal of suction but differ in the types of filtration systems they have on board.  Filtration in vacuum cleaners is the separation of air from debris as the air is forced through the filtration system core.
Vacuum cleaners that use filter bags have a system where the debris is sucked Hydraulic Pressure Filter Press
up from the flooring and the filter bag allows air to pass through and traps the debris in the bag separating the debris from the air.  Vacuum filter cleaner bags are usually made out of layered paper or a mixture of blown polypropylene and paper that is statically charged to attract dust.  Vacuum filter bags have the ability to remove sub micro pollutants from the air preserving the breathing environment.  The great feature about filter bags is that no matter how much debris you are vacuuming they are guaranteed to trap up to 95% of the debris moving through the vacuum filtration system.  The downside to filter bag vacuum cleaners is the actual cost of the filter bags themselves.  Vacuum filter bags usually range from 5 to 100 dollars a pack depending on the filtration efficiency and the size and style of bag.
Cyclonic and bag less vacuum cleaners use almost the same system as the filter bags but uses a canister to trap the debris instead of a filter.  Once the debris is trapped, the canister can be removed and emptied.  In cyclonic vacuum cleaners motors create a vortex within the canister.  As the debris and air are drawn up through the canister the heavy particles move china filter press
to the outside walls and are dropped to the bottom of the canister.  The clean air then moves through the motor and out the vacuum cleaner exhaust.  Cyclonic vacuums are great for normal vacuuming conditions but...
