Some of them are re-usable while others (made of paper) are disposable.

我的是 $45 一个，再加税，说是一年一换的。你的怎么这么便宜？

Lowest is about $8.00 and highest is about $50, depending on the sizes.

你这个不能洗，脏了就扔了。
家里人没有过敏用２块钱３个的就好，一个月扔一个。
要不就１００块买个电的

Home depot. The cheapest blue one is about 1 dollar a piece, replace it every month. There is cheap paper one last three month about 2 to 3 dollars.

The blue one only good enough to protect the furnace. The paper one is good for both furnace and improve air quality if you turn on furnace fan 24 hours.
If you don't turn on the fan 24 hours 1 dollar blue piece is good enough.

当初装这个贵的，就是希望改善空气质量。考虑到冬天封闭的空气循环，所以选了贵的。但是不能肯定钱花是不是值得。
