市面上充斥著許多名詞 “True HEPA ”HEPA pure”等。這些名詞基本上毫無意義,大多利用等級較差的濾網來混淆消費者。
基本上能夠達到99.97% 的過濾效率,直徑為 0.3 微米的顆粒才是屬於真正的HEPA。

What is HEPA?
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 99.95% 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.
