The pink 3M2097 respirator filters seem to be the default pancake style filters in most metal working environments because of their P100 rating. However, If you are mainly trying to filter out welding vapor and acetone fumes, with 95%+ filtration, the 3M2078 maybe worth a look and for substantially less money. Fits most 3M full and half face respirators.
Technical description:
NIOSH approved for environments containing certain oil and non-oil based particles. 3M recommended for relief against nuisance levels of organic vapor/acid gases and for ozone protection up to 10X OSHA PEL (permissible exposure limit). Use the 3M2078 white pancake style filters with: 3M™ 5000 Series Respirators or 3M™ Cartridge 6000 Series with the 3M™ Adapter 502. Also compatible with 3M™ Half and Full Facepieces series 6000, 7000 and FF 400 with "bayonet" style filter holders. When properly fitted, use for a variety of applications including dust, welding vapor, metal pouring and certain finishing operations for concentrations up to 10 times the Permissible Exposure Limit (PEL) with half facepieces or 50 times PEL with full facepieces. Also offers nuisance level relief from organic vapors and acid gases that are below the PEL. *Nuisance level refers to concentrations not exceeding OSHA PEL or other applicable government occupational exposure limits, whichever is lower. Full facepieces must be quantitatively fit tested to claim assigned protection factor above 10 in negative pressure mode. Respirators should only be used by clean shaven individuals. Do not use in for respiratory protection against organic vapors or acid gases or environments that are immediately dangerous to life or health (IDLH). Not NIOSH certified for use against ozone.
