加一层活性炭会降低颗粒净化效果吗?

Activated carbon air purifier VOC

我最近公布了活性炭的测试,发现活性炭真的能减少VOC。但是测试活性炭之后,我有疑问:

如果加一层活性炭,风扇的风阻会加大。这样会不会让大炮对颗粒的效果降低?

方法

为了测试这个问题,我在原来的15m2北京公寓做了10次房间测试。滤网顺序是:大炮 + 活性炭 + HEPA。

每次测试是整个晚上,用激光空气测试仪记录每小时的0.5微米和2.5微米及以上的颗粒。测试条件跟我之前的测试方式一样

结果

加了一层活性炭,颗粒效果降低1-2%,所以有影响,但是不是很大。

DIY 1.0力气没那么大。加活性炭后,DIY 1.0对0.5微米颗粒的效果降低19%,对2.5微米颗粒效果降低15%。

结论

为了需要活性炭的人,我建议在大炮上使用。但是DIY 1.0我不建议(或者可以单独用一台DIY 1.0加活性炭)。

跟之前一样,为了其他书呆子同胞们,我发布了原始数据和详细的方法,请看英文版本

Wait – what about effectiveness of the Sqair with carbon filter?! If it’s similar to the DIY, we should be skipping it (the carbon filter) too, no?
