Stfu.

Sheep?

Should be an expiry date on the box. Can use past expiry, but at lower efficiency.

@@justaknight4719 So, instead of saying "YOU DON"T KNOW." You tell me to read the expiration on the box of the P100 that I did not buy yet... Did it ever occur to you that the expiration date DOES NOT ANSWER THE QUESTION? The expiration date on this box says 12/28/2019. Does that mean it lasts negative three months long?

@@justaknight4719 Here's a link to the box. www.amazon.com/Dr%C3%A4ger-X-plore-3500-Multi-Gas-P100/dp/B01GVSYO10/ref=sr_1_3_sspa?keywords=p100+mask&qid=1582364332&sr=8-3-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExU1pVWllDVVRXNTMyJmVuY3J5cHRlZElkPUEwNDk5MjYyWkZUS1NBMVlYTkRFJmVuY3J5cHRlZEFkSWQ9QTAwOTY3NTIxUEM1NDZKNkxQMEdLJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==

@@charliechuckleberry5307 you've got to be some jackass to ask a question you could have clearly known there was an answer or non-answer to by reading the box..instead you opted to ask some other pylon on RU-vid about it. And when not getting the answer you wanted, you're door knob functioning ass for a brain decided to reply arrogantly about him not giving you the information you clearly know he did not have. Call the manufacturer you absolute donkey.

@@charliechuckleberry5307 how would he know? Each box is produced at a different time so each box would have a different expiry date on it. If they were on average good for 2 years that would still be meaningless information because you would have to look at the individual box of the one you're purchasing to see how long it is good for. I think you're being rude and overreacting to this person who is trying to be helpful. If you have one dated for December in 2019 as you state, don't use it, it's expired and the efficacy isn't going to be as good.

as you know you have 2 factor of tabaco smoke the smoke and oils from the nicotine so a mask with those rating should be preferred.
