I was wearing my respirator on the bike when the lower mainland (bc) was very smokey for a week or so with the northward drift of smoke from west coast fires. Then the new west pier caught on fire and added a couple more smoke filled days. The p100 filters did an amazing job of filtering the air. When i took my mask off at a light to sip some water, i couldn’t believe how poor the air quality was.
