What size dust particles can the double-precision filtration technology of a cordless smart vacuum cleaner effectively remove?

The double-precision filtration technology of the cordless smart vacuum cleaner is the core of its efficient cleaning performance. This technology ensures that the vacuum cleaner can capture and absorb dust particles of various sizes through a carefully designed filtration system, providing users with a clean and healthy environment home environment.
First, double-precision filtration technology usually consists of two main parts: a primary filter and a high-efficiency particulate filter (HEPA filter). As the first line of defense, the primary filter is mainly responsible for capturing larger particles and debris, such as hair, paper scraps, sand, etc. These larger particles, if sucked inside the vacuum cleaner, can clog the finer filters or damage the vacuum cleaner's motor. The primary filter is designed to effectively intercept these large particles, ensuring the smooth operation of the vacuum cleaner.
Next, the high-efficiency particulate filter (HEPA filter), as a key part of double-precision filtration technology, plays a vital role. HEPA filters are high-efficiency air filtration materials capable of capturing particles above 0.3 microns (μm). This size range covers many harmful particles such as pollen, bacteria, viruses, mold spores, dust mite allergens, etc. The HEPA filter has a filtration efficiency of 99.97% or higher, which means it can effectively remove these tiny particles, providing users with a fresher, healthier home environment.
The double-precision filtration technology of the cordless smart vacuum cleaner not only has excellent filtration effect, but also has some other advantages. First, it can significantly reduce the possibility of secondary pollution. Because the vacuum cleaner can effectively capture and absorb dust particles of various sizes, these particles will not be released into the air again, thus avoiding the problem of secondary pollution. Secondly, double-precision filtration technology can also extend the service life of the vacuum cleaner. Because the primary filter is able to intercept large particles, the HEPA filter does not become clogged quickly, thus extending the life of the filter. In addition, the cordless design makes the vacuum cleaner more flexible and convenient, allowing users to easily clean in different rooms and corners.
In short, the double-precision filtration technology of the cordless smart vacuum cleaner is the core of its efficient cleaning performance. Through the combination of primary filter and high-efficiency particulate filter (HEPA filter), it can effectively capture and absorb dust particles of various sizes, providing users with a clean and healthy home environment. At the same time, this technology also has the advantages of reducing secondary pollution and extending the service life of the vacuum cleaner, making the cordless smart vacuum cleaner an ideal choice for modern household cleaning.
