How does the Nail Vacuum Cleaner's filtration system work?

In the field of household cleaning, the performance of a vacuum cleaner is often closely related to the efficiency of its filtration system. As a high-performance cleaning device, the design of the filtration system of the Nail Vacuum Cleaner (hypothetical brand name, please replace it with a specific brand in actual application) is particularly critical, which is directly related to the cleaning effect, air quality and durability of the device.
The filtration system of the Nail Vacuum Cleaner is usually composed of multiple layers of filter materials, which intercept and capture tiny particles such as dust, dandruff, hair, allergens, etc. in the air layer by layer according to the size of the particles. Common filtration systems include primary filters, high-efficiency filter layers (such as HEPA filters), and possible activated carbon layers.
Primary filter: This is the first line of defense after the air enters the vacuum cleaner, mainly used to intercept larger particles, such as dust clumps, debris, etc. The design of the primary filter is usually rough and easy to clean and replace to protect the subsequent filter layers from direct impact of large particles.
High Efficiency Particulate Air (HEPA) filter: The HEPA (High Efficiency Particulate Air) filter is known for its extremely high filtration efficiency, which can capture particles as small as 0.3 microns in the air, including pollen, bacteria, viruses, and some allergens. In the Nail Vacuum Cleaner, the HEPA filter is usually located after the primary filter to further purify the air and ensure that the exhausted air is almost free of any harmful particles.
Activated carbon layer (optional): Some high-end models of Nail Vacuum Cleaners may also be equipped with an activated carbon layer to absorb harmful gases and odors in the air. Activated carbon has a strong adsorption capacity due to its porous structure, which can effectively improve indoor air quality.
Working principle
When the Nail Vacuum Cleaner is turned on, the motor drives the fan to rotate, generating a strong suction force to suck dust and debris from the ground or furniture surface into the vacuum cleaner. The air and particle mixture first passes through the primary filter, where most of the large particles are intercepted and deposited on the filter surface. The initially purified air then continues to flow to the high-efficiency filter layer (such as the HEPA filter), where smaller particles are captured and retained inside the filter. If the vacuum cleaner is equipped with an activated carbon layer, the air filtered by the HEPA filter will further pass through the activated carbon layer to remove harmful gases and odors.
Finally, the clean air that has been filtered layer by layer is discharged from the exhaust port of the vacuum cleaner and returned to the indoor environment. The dust and particles captured on the filter need to be cleaned or replaced regularly to keep the filter system in good working condition and cleaning effect.
In order to maintain the optimal performance of the Nail Vacuum Cleaner filtration system, it is essential to clean and replace the filter regularly. Check and clean the primary filter regularly to prevent it from clogging and affecting suction. At the same time, the HEPA filter and activated carbon layer (if equipped) also need to be replaced according to the manufacturer's recommended cycle to ensure their filtration efficiency and service life.
