How does the CR201 vacuum cleaner's 5-stage high-efficiency filtration system work to ensure that the dust and particles sucked in are firmly locked?

Stage 1: Pre-filtration
Function: Prevent larger particles and debris from entering the vacuum cleaner.
How it works: This is usually done through the vacuum cleaner's pre-filter or mesh structure. These structures can initially filter out larger particles, such as hair, paper scraps, etc., to prevent them from entering the subsequent filtration system.
Stage 2: Cyclone separation
Function: Use cyclone technology to separate dust and air.
How it works: When the air and dust mixture enters the vacuum cleaner, they are guided into the cyclone separation chamber. Here, the high-speed rotating airflow generates centrifugal force, throwing dust particles against the wall of the cyclone chamber, thereby achieving a preliminary separation of dust and air.
Stage 3: HEPA filtration
Function: Capture tiny dust particles, including microorganisms such as bacteria and viruses.
How it works: The HEPA (High Efficiency Particulate Air) filter uses a fiber-arranged mesh structure that can effectively capture particles with a diameter of 0.3 microns or more. This filter has a very high filtration efficiency and can capture more than 99.97% of the tiny particles in the air.
Stage 4: Additional filter layer (if any)
Function: Further filter out the tiny particles that may be missed and absorb odors and harmful gases.
Implementation: In some high-end vacuum cleaners, there may be additional filters made of activated carbon or other chemical materials. These filters can absorb and remove harmful chemical pollutants such as odors and formaldehyde in the air.
Stage 5: Exhaust filtration
Function: Ensure that the final exhaust air is clean and prevent any tiny dust particles from escaping.
Implementation: At the exhaust port of the vacuum cleaner, an additional layer of filter material, such as a fine filter or foam, is usually set. This layer of filter material can further block the tiny particles that may be missed by the previous stage, ensuring that the final exhaust air is clean.
