What are the functions of the filters equipped in pet vacuum cleaners?

The filters equipped in pet vacuum cleaners play a vital role in the working process of vacuum cleaners. Their main purpose is to filter dust, tiny particles and pollutants in the air to protect the internal components of the vacuum cleaner, such as motors and circuit boards, while improving the indoor air quality. The following is a specific description of the functions of the three filters you mentioned (metal mesh filter, sponge filter, HEPA filter):
Metal mesh filter: The metal mesh filter is mainly used to filter out larger particles, such as pebbles, metal fragments, etc., to prevent them from entering the interior of the vacuum cleaner, thereby protecting the motor and circuit boards from damage. Due to the strong suction power of the vacuum cleaner, it is possible to inhale larger particles, which may cause circuit short circuits or motor damage after entering the interior of the vacuum cleaner. The metal mesh filter can effectively block these large particles, thereby extending the service life of the vacuum cleaner.
Sponge filter: The sponge filter is an important filter in the vacuum cleaner. It mainly plays the role of filtering tiny particles such as dust and pollutants in the air. The material and structure of the sponge can capture and absorb these tiny particles to prevent them from entering the interior of the vacuum cleaner. The cleanliness and quality of the sponge filter will directly affect the performance of the vacuum cleaner. If the sponge filter is clogged, the suction power of the vacuum cleaner will decrease and the cleaning effect will be affected. Therefore, regular cleaning and replacement of the sponge filter is the key to maintaining the performance of the vacuum cleaner.
HEPA filter: The HEPA filter is a high-efficiency air filter that can filter out particles with a diameter of 0.3 microns or more, including microorganisms such as dust mites, pollen, bacteria and viruses. The mesh structure of the fiber arrangement of the HEPA filter enables it to effectively capture fine dust particles, ensuring that the dust generated during the cleaning process is no longer dispersed, thereby improving the indoor air quality. The HEPA filter is particularly important for people with allergies or pet families. It can effectively remove allergens and bacteria in the air, providing family members with a healthier and more comfortable living environment.
In summary, the filter equipped with the vacuum cleaner plays an important role in protecting the internal components of the vacuum cleaner and improving the indoor air quality. Different types of filters have different filtering effects and importance. Users should choose the appropriate filter according to actual needs when using the vacuum cleaner and clean and replace it regularly.
