μm1、长度单位微米是长度单位，符号 [micron]。
1微米相当于1米的一百万分之一（此即为「微」的字义）。

网目是表示标准筛的筛孔尺寸的大小。
在泰勒标准筛中,所谓网目就是2.54厘米(1英寸)长度中的筛孔数目,并简称为目。
泰勒标准筛制：泰勒筛制的分度是以200目筛孔尺寸0.074mm为基准，乘或除以主模数方根（1.141）的n次方（n＝1，2，3……），就得到较200粗或细的筛孔尺寸，如果数2的四次方根（1.1892）的n次方去乘或除0.074mm，就可以得到分度更细的一系列的筛孔尺寸.目数越大，表示颗粒越细。
类似于金相组织的放大倍数。
目数前加正负号则表示能否漏过该目数的网孔。
负数表示能漏过该目数的网孔，即颗粒尺寸小于网孔尺寸；而正数表示不能漏过该目数的网孔，即颗粒尺寸大于网孔尺寸。
过滤器分级标准
由于现在许多企业选用的是进口的过滤器，而它们表示效率的方法与国内的不同，为便于比较，将它们之间的换算关系列表如下：
按欧洲标准，粗效过滤器分为四级（G1~~G4）：
G1 效率对粒径≥5.0μm,过滤效率E≥20% (对应美国标准C1)
G2 效率对粒径≥5.0μm,过滤效率50＞E≥20% (对应美国标准C2~C4)
G3 效率对粒径≥5.0μm,过滤效率70＞E≥50% (对应美国标准L5)
G4 效率对粒径≥5.0μm,过滤效率90＞E≥70% (对应美国标准L6)
中效过滤器分为两级(F5~~F6)：
F5 效率对粒径≥1.0μm,过滤效率50＞E≥30% (对应美国标准M9、M10)
F6 效率对粒径≥1.0μm,过滤效率80＞E≥50% (对应美国标准M11、M12)
高中效过滤器分为三级（F7~~F9）：
F7 效率对粒径≥1.0μm,过滤效率99＞E≥70% (对应美国标准H13)
F8 效率对粒径≥1.0μm,过滤效率90＞E≥75% (对应美国标准H14)
F9 效率对粒径≥1.0μm,过滤效率99＞E≥90% (对应美国标准H15)
亚高效过滤器分为两级(H10、H11)：
H10 效率对粒径≥0.5μm,过滤效率99＞E≥95% (对应美国标准H15)
H11 效率对粒径≥0.5μm,过滤效率99.9＞E≥99% (对应美国标准H16)
高效过滤器分为两级(H12、H13)：
H12 效率对粒径≥0.5μm,过滤效率E≥99.9% (对应美国标准H16)
H13 效率对粒径≥0.5μm,过滤效率E≥99.99% (对应美国标准H17)

备注：大气尘与实验室所用的当地合成尘相比，大气尘的粒径范围更广泛，因此实验室的测试结果不能作为衡量过滤器实际操作性能和使用寿命的基础。
一般通风用过滤器更换
空调系统中，每个过滤段都应设阻力监测装置。
根据终阻力确定过滤器更换与否。
也可根据经验，根据实际情况，适时调整更换终阻力。
建议：设定最长使用周期，根据周期与终阻力值，选定最低值来确定过滤器更换
与否。
