Vacuum Cleaner Filter

The Vacuum Cleaner Filter is an essential component in modern household appliances, designed to significantly improve indoor air quality by effectively filtering out pollutants such as dust, pollen, smoke, bacteria, and viruses. At Air Guard, we are committed to providing filters that meet the diverse needs of various environments and applications, ensuring a healthier and more comfortable living space for your family.

Vacuum Cleaner air Filter System

The filters in a vacuum cleaner play a crucial role in its operation. They not only determine the cleaning efficiency of the vacuum cleaner but also directly affect its lifespan and the safety of its motor. The vacuum cleaner filter system typically includes multiple components such as the pre-filter, main filter, and motor protection filter, each serving different functions and working together to ensure the efficient operation of the vacuum cleaner.

Pre-filter

The pre-filter serves as the first line of defense in the vacuum cleaner filter system. Its main function is to capture larger particles, such as dust clumps, hair, paper scraps, etc., preventing them from entering the main filter. By doing so, the pre-filter significantly reduces the pressure on the main filter, extends its lifespan, and prevents it from becoming saturated and clogged too quickly, which would reduce filtering efficiency.
The structural design of the pre-filter often focuses on increasing dust capacity and improving adsorption capacity. For example, a cyclone design is used to separate particles from the airflow through centrifugal force and collect them in the pre-filter’s container. This design not only improves filtering efficiency but also makes cleaning and maintenance simpler and more convenient.

Main Filter

The main filter is the core component of the vacuum cleaner filter system. It is responsible for capturing finer particles, such as dust mites, pollen, bacteria, etc., ensuring that the air expelled by the vacuum cleaner is clean . The filtering efficiency and lifespan of the main filter directly affect the overall performance and user experience of the vacuum cleaner.
To improve the filtering efficiency and lifespan of the main filter, high-precision filtering materials and technologies are often used. For example, a HEPA (High-Efficiency Particulate Air) filter is a commonly used type of main filter that can capture 99.97% of particles larger than 0.3 micrometers in diameter. Additionally, the main filter needs to be cleaned or replaced regularly to maintain its good filtering performance.

Motor Protection Filter

The motor protection filter is located between the motor and the dustbag. Its main function is to protect the motor from being harmed by dust and particles. During the operation of the vacuum cleaner, the motor is the key component that drives its operation. If dust and particles enter the motor, it can cause overheating, wear, and even damage to the motor. Therefore, the presence of the motor protection filter is of great significance for extending the lifespan of the vacuum cleaner and ensuring user safety.
The motor protection filter is usually made of fine filtering material that can effectively block dust and particles from entering the motor. At the same time, it also needs to have good air permeability to ensure that the motor can obtain sufficient air circulation and cooling during operation.
