没啥用吧。
建议入个空气净化器

嗯这个可以考虑

high efficiency主要是在燃烧、隔热、热交换上做文章,风扇输出功率主要是用来克服风阻。风阻是管道形状、长度决定的,基本上是房子的形状说了算

那个800W电机,效率上能够提高的空间非常有限,所以厂家一般都不去打它的主意
普通电机和高校电机的效率只差两三个百分点,和没有一样

所以风扇还是放在自动档最节能

800瓦其实也就是普通家用吸尘器功率的一半而已,也不是很大。但是一天24小时运转,可以耗20度电。等级3的电费可以是7刀,一个月要200刀。

原来这个风扇耗电这么多啊
Noticed folks picking MERV 10 and MERV 13 filters as a result of the flat pricing on this deal. Note that the general consensus among HVAC professionals is that MERV 5-8 is the ideal filter for residential HVACs except in specific situations.
These filters are meant to keep your HVAC systems clean. They are not meant to clean your air.If you want to clean your air, get a standalone HEPA air purifier. Higher MERV rating = higher resistance to air flow = higher static pressure. Higher static pressure = more strain on your blower
