冇得咁計架 bor. 好睇你响: 我愛大自然環境, 定係毒氣密室?
總之, 用呼吸器, 係唔應該聞到化學品味. 同埋呼吸困難.
聞到嘢, 即係
1. fit 有問題 (要做 user seal check: positive and negative), size 錯了, 或太鬆
2. 本身揀錯 filter cartridge
3. 個 filter cartridge 要換 (特別係 cartridge)
user seal check (一定要做):

P100 filter 舊係好難呼吸, 因物理性塞晒
cartridge 舊, 係會有味, 再冇能力吸化學品
下面係 3M 自己噏嘅:
The service life (i.e. how long it will last) of any gas
and vapor cartridge filter is affected by many factors
– some being: concentration and identity of contaminants,
breathing rates, humidity levels, ventilation, temperature,
carbon exposure time etc.
Once opened, maximum use time is 6 months (even if
not used). The carbon will absorb contaminants from
the general environment.
即係 600X 同 6092X 因佢地都係 gas/vapor cartridge, 開咗六個月就要換, 即使冇乜用過.
假如係用 600x + 502 + 2xxx p100 嘅人, 應考慮每次大裝修後換走 2xxx p100, 用新嘅. 因主力係, 2xxx 做嘢. 600x 係捉漏網之魚啫
