I use a North 7700 series half mask that does not leak at all. The only complaint I have with it is that because of my huge honkin' nose, it gets a little uncomfortable after a couple of hours. They are not expensive, the cartridges are HEPA, inexpensive, & last a long time. Several months of heavy hobby use. Just blow em out backwards when they start to plug up.
A good acid test for sealing is to use the organic vapor cartridges & then spread a bunch of nasty smelling finish around. Any leak at all & you'll smell the solvent.
Respirators are a bit of a personal thing, you need to find one that is comfortable & seals well on your face
I've been using a dual canister 3m painting mask for awhile and it seems to be okay. Sometimes I have issues with tasting dust when sanding though, especially with the belt sander. But recently it seems the straps are getting too stretched out and it won't fit right.
What respirators are popular these days for sanding and painting?
Hey everyone, need some advice on a plane purchase. I've been looking for a smoothing plane for a little bit mostly on ebay. Every no 4 Stanley gets snatched up for prices I don't want to pay. They are going for about 50 bucks. Is that too high for these. Also have been looking at the woodriver no 4. I can't afford a LV or LN, but can justify the 160 for the wood River. So I guess my question is go for the woodriver or take a chance on the old Stanley.
