The current vacuum cleaners mainly have the following three filtration methods, namely, dust bag filtration, dust cup filtration and water filtration. The dust bag filter type filters out 99.99% of particles as small as 0.3 microns, which is more convenient to clean as a whole. However, the vacuum degree of the vacuum cleaner that uses the dust bag will decrease with the passage of time, which causes the suction power to become smaller, and it is cleaning the dust bag. Sometimes hidden mites may cause secondary pollution to the surrounding environment. The dust cup filter type separates garbage and gas through the high-speed rotating vacuum airflow of the motor, and then purifies the air through HEPA and other filter materials to avoid secondary pollution. The advantage is that the dust bag does not need to be replaced frequently, and the disadvantage is that it needs to be cleaned after vacuuming. . The water filtration type uses water as a filter medium, so that most of the dust and microorganisms will be dissolved and locked in the water when passing through, and the remaining will be further filtered after passing through the filter, so that the exhaust gas when discharged from the vacuum cleaner may be more than the air when inhaled. It is cleaner, and the overall suction power is significant, but the price is relatively high. It must be cleaned after use, otherwise it is easy to mold and smell. The key point of purchasing a vacuum cleaner at home is to look at the filter system. Generally, the higher the material density of the multiple filter, the better the filtering effect. The efficient vacuum cleaner filter can retain fine dust and prevent secondary pollution from flowing out of the machine. . At the same time, we need to look at the noise, vibration, and stability of the motor.
