advantage:
Efficient filtration: capable of removing over 99.97% of 0.3 micron particles, suitable for various environments.
Physical filtration: does not produce secondary pollution, safe to use.
Disadvantages:
High wind resistance: Efficient HEPA filters increase the resistance to air flow, which requires high demands on the fan.
Replacement cost: Regular replacement of the filter element is required, which increases the usage cost.
In summary, HEPA air purifiers effectively purify air through various physical mechanisms, making them particularly suitable for environments that require high air quality.
