中文简体Pre-filters are an important part of any air purifier. They help capture larger airborne particles, like dust and pet hair, while also extending the life of the main HEPA filter. This makes the system run cleaner and more efficiently.
Some pre-filters are washable. This makes them easier to clean, which is another good reason to own one. However, they should be replaced only when they become physically damaged.Besides capturing more particles, a pre-filter can also reduce odors. Some models are even smart enough to target specific odors.
Using a pre-filter will also help you avoid straining your HEPA filter, which can cause it to malfunction. Cleaning your pre-filter once a month is usually all it takes. Using a vacuum cleaner is also a good way to keep your pre-filter healthy.

HEPA stands for High Efficiency Particulate Air. It is a standard defined and developed by the U.S. Department of Energy during the 1940s as part of their efforts to contain the spread of particles and contamination resulting from nuclear testing. This standard has since moved into the consumer market and has become commonplace for air purifiers.
To meet the HEPA standard, the filter must remove 99.97% or more of all particles which are 0.3 microns (micrometers) in diameter. In other words, for every 10,000 particles that are 0.3 microns in diameter, only three of them pass through.
The HEPA standard traps very small particles,many of which are invisible to the human eye and harmful to your health. To provide perspective for size, human hair is approximately 80-100 microns in diameter.
