Hi! I'm a new member of this forum. Hope to get help from all of you! Thanks!
+1 thumb upI give a thumbs up to the 3M 7500 series with either 2097 or 2297 filters. I like the 2297 a bit more because they have "P100, nuisance organic vapor relief particulate filter". For light exposure to finishes, the extra vapor protection is nice.
Awesome info all. I would add the acid test is if a cartridge filer is harder to breathe through after use, it's time to swap out. Depending on substance many cartridges are only good for one exposure, not to exceed 15 minutes. Any folks around Ammonia know this, or should. Wood products are probably going to be seeing an increase in respiratory effort to suggest a swap is needed. Not having been around ALL finishing products I don't know if there are some that are filter killers. Believe me you will know.The mask model is about fit and comfort. The filter cartridges are probably the most important thing to pay attention to. There are different cartridges for different applications: particulate filters for sawdust, organic vapor cartridges for finishing, etc. If you use the wrong cartridge, it won t protect you.
They make combination cartridges that protect against multiple hazards. Be aware, however, that the useful life of a cartridge varies considerably depending on its type. An organic vapor cartridge is good for something like 8-10 hours of use (not sure what the exact time is), but a particulate filter might be good for months (if you are a hobbyist like me). The combination cartridges will have different useful lifespans for different types of hazards-so don t think you can use a combo cartridge for finishing after you have used it for 30 hours to protect against sawdust.
