HEPA filters come in different shapes, sizes, configurations and products. 为了我们的目的, 我们提供HEPA过滤设备作为我们的过敏深层清洁包的一部分, which covers HEPA vacuuming of air vents as well as air filters, 等. HEPA stands for “High Efficiency Particulate Air,” and it is used in a variety of applications such as air filters, vacuum bags and other types of contamination control. To carry its designation, a HEPA filter must trap 99.97%的微粒0.3微米或更大. If you suffer from allergies, HEPA过滤器是你的朋友，因为它们比传统过滤器含有更多的颗粒和污染物.
