1. Air quality

冬季我们很少开窗通风换气，所以通风管道中很容易积尘，如：毛发以及皮屑，从室外带来的灰尘和污物，从衣服和地毯上脱落的细毛，蜘蛛、甲虫等虫子，建筑和装修垃圾，甚至还会有小老鼠的尸体等等。而这些东西如果不用特殊的设备是不可能清理出来的，而暖风炉的过滤网的作用很有限，它不能阻止灰尘和细毛在室内循环。

In winter, we seldom open windows for ventilation, so it's easy for dust to accumulate in the ventilation ducts, such as hair and dander, dust and dirt brought from outside, fine hair falling off clothes and carpets, insects such as spiders and beetles, construction and decoration garbage, and even the bodies of mice. It is impossible to clean these things without special equipment, and the function of the filter screen of the heater is very limited, it can not prevent the dust and fine hair from circulating indoors.
