每个房间的9 HEPA空气净化器和品牌

HEPA空气过滤器做什么？

HEPA过滤器从空气中从灰尘，霉菌，花粉，细菌，病毒等中去除微小颗粒。将薄玻璃纤维随机排列成浓密的纸状材料，该材料被折叠成褶皱以创建过滤器。

当空气颗粒通过这些过滤器时，污染物被困在纤维中。然后，当较大的颗粒粘在过滤器上时，它们使其他较小的颗粒无法通过。HEPA过滤器可能会捕获至少小的颗粒0.3微米。作为参考，人眼可以看到的最小的东西是25微米, and a strand of hair is between17和180微米in diameter.

When placed into filtration systems like air cleaners and净化器，HEPA过滤器可以删除99.97％空气中的颗粒。这些过滤器最初是在核电厂中使用的，但是许多新设备都将该技术用于可以帮助您清洁房屋空气的产品。

过滤器的类型

有许多类型的空气过滤器和空气净化设备可供家庭使用。HEPA过滤器可用于清洁设备，空气过滤器，便携式空气清洁剂，全家风扇系统，供暖和冷却单元等。目的是在通过这些设备中过滤微小的微粒。

HEPA过滤器aren’t the only way to do this, but they are recognized as highly effective, filtering some of the smallest particles from the air. Other examples of filters include:

• Ultra-Hepa过滤器或ULPA过滤器。这些可以陷入99.999％颗粒0.3微米或更小。
• 静电过滤器。这些使用小静电电荷的捕获颗粒，可帮助颗粒粘在过滤器上。
• 静电迫使。这些过滤器使用金属板或电线以相反的电荷吸引颗粒。它们通常可以洗涤和重复使用。
• 电离。这些过滤器依赖于散发出磁性吸引空气中颗粒的小电荷。这种过滤可能会释放臭氧气体，并可能引起呼吸道疾病患者的刺激。

我们如何选择HEPA空气净化器

在房屋清洁方面，有很多选择，而且选择会变得压倒性。尽管EPA不认证或推荐特定类型的空气过滤器，但该机构确实提供了为您选择合适产品的建议。这些recommendations是我们选择过程的基础，包括以下考虑。

• 大小事项。寻找专为您尝试使用的房间尺寸而设计的便携式过滤器。通常，过滤器的清洁空气输送率（CADR）得分应等于大约two-thirds房间里的区域。
• 避免产生臭氧的空气清洁剂。Ozone is a gas that is released during some air purification processes. While ozone gas is meant to clean and sanitize air, it’s also considered a pollutant that can cause irritation and damage to the lungs when inhaled. Air cleaners that use ozone are generally intended for rooms that are uninhabited at the time of use. They are not for use in confined spaces when you are present. No government agency in the United States hasapprovedany ozone generators as air cleaners in homes.
• 查看行业评级。尽管EPA没有为这些过滤器设定规则，但有些行业领导者设定了HEPA过滤的标准。购买过滤器时，应符合以下标准之一：
  • designated HEPA filter
  • Cadr评分
  • 制造商指出产品过滤大多数小于1微米的颗粒

Pricing guide

空气净化器的价格取决于其尺寸，功能以及它过滤空气的效果。价格从100美元到数千美元不等。在大多数商业网站上，您将能够通过过滤和价格范围自定义搜索，以找到最适合您的需求和预算的模型。

HEPA空气净化器的优点和局限性

When choosing an air purifier, keep in mind that you should purchase your device based on room size and filtering ability. Also, the device can only filter as well as you maintain it. A dirty or expired HEPA filter will not do its job well. Check the manufacturer’s recommendation on filter replacement. Generally, these should be switched every60至90天。

You should also be sure to follow the manufacturer’s recommendations on placement, operation, and maintenance for best results.

Overall, consider why you want an air purifier, how well the device you are considering filters air, and your budget. Some units may have an attractive price, but it all comes down to how well a unit will filter the air in the size of the room you will be using it in.
