I have looked through some of the old posts on respirators but can find nothing on this little problem I have when using the one time respirators. I've tried a few different makes but have the same problem with them all. I use a respirator when strimming - long grass - small brush - and when spraying our olive trees and using sanders etc. Can anyone tell me whether the permanent masks where you just change the filters are any better in this regard? I've looked for example at the 3M 6502QL and others like it. I have no idea how good these would be. As you can see from the use I make of a mask, apart from spraying the olives, the mask is just to keep dust and pollen out.
Any advice would be appreciated - I'm not worried about the cost so much as the comfort and convenience - and most of all being able to see what I'm doing!
