空氣濾清器的濾芯分為干式濾芯和濕式濾芯兩種。干式濾芯材料為濾紙或無紡布。為了增加空氣通過面積，濾芯大都加工出許多細(xì)小的褶皺。當(dāng)濾芯輕度污損時(shí)，可以使用壓縮空氣吹凈，當(dāng)濾芯污損嚴(yán)重時(shí)應(yīng)當(dāng)及時(shí)更換新芯。
  


 濕式濾芯使用海棉狀的聚氨脂類材料制造，裝用時(shí)應(yīng)滴加一些機(jī)油，用手揉勻，以便吸附空氣中的異物。如果濾芯污損之后，可以用清洗油進(jìn)行清洗，過分污損也應(yīng)該更換新濾芯。

如果濾芯阻塞嚴(yán)重，將使進(jìn)氣阻力增加，發(fā)動(dòng)機(jī)功率下降。同時(shí)由于空氣阻力增加，也會(huì)增加吸進(jìn)的汽油量，導(dǎo)致混合比過濃，從而使發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)狀態(tài)變壞，增加燃料消耗，也容易產(chǎn)生積炭。平時(shí)應(yīng)該養(yǎng)成經(jīng)常檢查空氣濾清器濾芯的習(xí)慣。
