Guys, I use a 3M 6000 series mask. I got it in Canada with a pair of 60926 cartridges - P100 and multi-vapour all in one - overkill for what I spray, true, but never a whiff of anything through it so far.

3M don't stock these particular cartridges downunder and their workaround solution is a bit cluttered but you can get them via Amazon for about $US20.00 a pair plus freight. Amazon's supplier "Allergy be Gone" was the vendor but the Amazon purchasing/payment process deals with the money/address etc..... Ordered 23/11, arrived Auckland 25/11 scheduled to deliver today. Fellow "finishers" might like to check this out. Best to get a few packs to dilute the freight cost though. Best regards
