濾毒盒裝填優(yōu)質(zhì)活性炭或活性炭—催化劑，能夠防護不同種類毒劑，防護時間長，阻力小，重量輕，更換方便。
3技術(shù)指標(biāo)
3.1面罩漏氣系數(shù): ≤0.005%（30L/min）
3.2呼氣阻力:≤100Pa（30L/min）
3.3視野: 總視野:≥75%
雙目視野: ≥55%
下方視野: ≥35度
3.4面罩鏡片透光率：≥85 %
3.5防護時間:同選定濾毒盒的性能，見表1。
表1 濾毒盒性能
| 濾毒盒 編號 | 標(biāo)色 | 防護對象 | 試驗毒劑 | 防護時間（min） |
| 3 | 褐色 | 有機氣體 | 苯 | ≥45 |
| 4 | 灰色 | 氨、硫化氫 | 氨 | ≥25 |
| 7 | 黃色 | 酸性氣體 | 二氧化硫 | ≥30 |
4使用和維護
4.1佩戴面具時,先檢查面罩氣密。即取下面具上的濾毒盒后，將面罩由下巴處向上佩戴,再適當(dāng)調(diào)整頭帶,面罩的密合框應(yīng)與佩戴者面部密合，吸氣時不產(chǎn)生漏氣，則表明面罩已佩戴氣密,使用時安裝好濾毒盒后，方可進入染毒區(qū)域。
4.2 面罩使用后，鏡片、呼氣活門、吸氣活門要保持清潔，必要時可用水沖洗面罩。
