Filtration in a vacuum cleaner is essential for maintaining indoor air quality and efficiently collecting dust and debris. The device employs a combination of mechanical and electrostatic filtration methods to separate particulates from the airstream. As air is drawn into the vacuum cleaner through the nozzle, it passes through a series of filters, typically consisting of pre-filters and HEPA (High-Efficiency Particulate Air) filters. Pre-filters capture larger particles, preventing them from clogging the more delicate HEPA filter, which can trap particles as small as 0.3 microns with an efficiency of 99.97%. This multi-stage filtration system not only facilitates the hygienic disposal of captured debris but also minimizes the recirculation of allergens, dust mites, and other particulate matter, thereby improving the overall air quality within living spaces. Additionally, some vacuum cleaners incorporate activated carbon filters to mitigate odors, enhancing the cleaning experience.
