I'd def say for training unless much more info is provided. Wouldn't rely on no-name surp filters for serious scenarios. They're not in a sealed mylar bag or anything so it'd be hard to say how good the charcoal still is. Good for a workout as it limits airflow but like that other guy said, if it has asbestos and chromium, only thing it's worth for is LARPing. MIRA Safety is having a clearance event on their previous model CBR"N" filters and with some cart trickery you can get them for a descent price. Tho a big common misconception, considering the current global sociopolitical events, if I understood what i read correctly, is that most CBR"N" filters don't deal with the radioactive iodine itself but merely the particulates that carry it. So you gotta combine most CBRN filters with some thyrosafe unless specifically spec-ed to handle radioactive iodine.
