Filtering method of the best vacuum cleaners

The best vacuum cleaners have a history of 100 years,for many people, it has become an indispensable household equipment, the reason is obvious.Current controlled motor operation. With a fan, the fan blade has a certain angle, just like the propeller of an aircraft.When the fan blade rotates, the air is pushed to the exhaust port.When the air particles are pushed forward, the particle density in front of the fan will increase, and the air pressure will increase accordingly, and the particle density in the rear of the fan will be reduced.

   What is the filtering method of the best vacuum cleaners?

   Filtering method of the best vacuum cleaners---Dust bag filter

   It filters by the dust bag and HEPA filtration material,it should always replace the dust bag: It filters out 99.99% particles which is as low as 0.3 microns in size.It must replace the dust bag at the end of each use,it uses a dust bag as a filter, the cleaning is convenient, it does not need to clean every day.

   Filtering method of the best vacuum cleaners---Dust cup filtration

   The dust cup depends on the filter material such as cyclone duct and HEPA.A key to dust, cleaning is convenient:The dust cup filters separates the garbage and the gas by high speed rotating vacuum air flow.It can purify the air by HEPA and other filter material, so as to avoid the two pollution.The advantage is that the dust bag is not frequently changed; the disadvantage is that the cleaning is completed after the dust cleaning is completed. 

   Filtering method of the best vacuum cleaners---Water filtration

   Water filtration using water as filter media makes that when dust and microbes are passing,most of them will be dissolved in water, and the rest will be further filtered through the filter,which makes it possible to discharge the exhaust gas from the vacuum cleaner. The advantages are dry and wet use; the disadvantage is that after the cleaning is completed, it is to be cleaned up.
