F7 过滤器 - 颗粒物质和花粉
过滤器等级
过滤器有不同的等级，这些等级表示过滤器对微粒物质/灰尘或其他可从空气中过滤掉的物质的保护程度。
Airfixr 使用的是 F7 过滤器，其中 F 代表精细。
它能从大到小过滤空气中的动物毛发、粗灰尘、花粉和颗粒物。
F7 过滤器
F7 过滤器是一种微粒过滤器，可以过滤空气中从粗到极细的灰尘颗粒、花粉和动物毛发。这使得 Airfixr 非常适合过敏症患者使用。它还能过滤烟雾和废气。
该过滤器已通过 ISO 16890 认证。
颗粒物质
颗粒物是漂浮在空气中的微粒的总称。这些小颗粒经常成为荷兰的新闻，世界卫生组织（WHO）和荷兰环境与健康研究院（RIVM）也在其网站上公布了相关案例。下面是它们有关这一主题的网站链接。

微粒物质也存在于室内，因此，如果室内微粒物质含量较高，也会对健康造成危害。
花粉和宠物过敏
除了微尘，F7 过滤器还能净化空气中的动物毛发和花粉。
F7 filter – Particulate matter and pollen
Filter classes
Filters can be found in different classes that indicate the extent to which the filters protect you against particulate matter / dust or other things that can be filtered out of the air.
The filter used in the Airfixr is an F7 filter, where the F stands for Fine.
This filters the air from large to small: animal hair, coarse dust, pollen and particulate matter.
F7 filter
The F7 filter is a particulate filter, which filters coarse to very fine dust particles, pollen and animal hair from the air. This makes the Airfixr extremely suitable for people with allergies. It also filters smoke and exhaust fumes.
The filter is ISO 16890 certified.
Particulate matter
Particulate matter is a collective term for particles floating in the air. These small particles have often been in the news in the Netherlands, and the WHO and RIVM have published cases about them on their websites. Below are links to their websites on this subject.

Particulate matter is also found indoors and is therefore also harmful to health when present there to a higher degree.
Pollen and pet allergy
In addition to fine dust, the F7 filter purifies the air of animal hair and pollen, so in a room where Airfixr is in use, people with hay fever or pet allergies will not suffer from any complaints with their eyes and airways.
