Filtration is a crucial aspect of modern vacuum cleaners, playing a vital role in maintaining indoor air quality and ensuring efficient cleaning performance. Advanced filtration systems, such as HEPA (High-Efficiency Particulate Air) filters, are designed to capture and retain up to 99.97% of particles as small as 0.3 microns, including dust, pollen, pet dander, and other allergens. These filters work by forcing air through a fine mesh that traps harmful particles, preventing them from being released back into the environment. Additionally, multi-stage filtration systems often combine HEPA filters with other types of filters, such as carbon or foam, to enhance the vacuum’s ability to capture a broader range of contaminants. Effective filtration not only improves the cleanliness of your home but also contributes to better respiratory health by reducing the presence of airborne irritants.
