What's better for a vacuum cleaner?
Household vacuum cleaner key depends on the filtration system of choose and buy, often multiple filter material density is higher, the better filtering effect and will be, efficient vacuum cleaner filter can to retain the fine dust, prevent the outflow of closed to cause secondary pollution. It also depends on the noise, vibration and running of the motor.
Water filtration type water is used as filter medium, make the dust and microorganism during through most of the lock in the water, will be dissolved after the remaining again through the filter is further filtering, makes the exhaust of the exhaust cleaner can be compared to when they are inhaled air cleaner, suction significantly, but the price is relatively high, must be cleaned after use, otherwise easy to mildew stunk.
Dust cup high speed rotary vacuum filter type is by motor air separation of garbage and gas, again through the HEPA filter material such as clean air, so as not to cause secondary pollution, dust bag advantage is often don't have to change, clean up after the defect is vacuuming.
The current vacuum cleaner mainly has the following three kinds of filtering, namely dust bag filter, dust cup filter and water filtration 3 kinds. Dust bag filter type filter out 99.99% low of 0.3 micron particle size, overall clean up more convenient, but using dust bag vacuum cleaner with the passage of time, the vacuum will decline, lead to the suction smaller, when cleaning the dust bag hidden mites or can produce secondary pollution on the surrounding environment.
