怎样换Furnace Filter

[xifeng]

买了个新的Filter,发现有箭头指出了风的方向，忘了看旧的方向了，哪位指教一下,风是从上向下还是从下向上的？就是安装时Filter上的标出的箭头向上还是向下?谢谢了。

It depends on the furnace. usually air is go from down to up. But some furnace go other way.
One way to check, is air should go to the heat exchanger (where the fire is.) The vent level the exchanger is heating vent. Another vent goes back the furnace is the return vent where air come from. The filter is between return vent and heat exchanger. You filter should have two side. One side is all paper. All paper side should face incoming air.
