3M use notes for the 2078
Nuisance level refers to concentrations not exceeding the OSHA PEL or applicable government occupational exposure limits, whichever is lower. Nuisance-level relief is a 3M suggestion, not a NIOSH approval class. (3M Cartridge and Filter Summary (2024) note 2; 3M 6000 Series half facepiece user instructions Table 7 footnote 3)
2078 is 3M recommended for use against up to 1 ppm ozone for up to 40 hours. Not NIOSH or Brazil Ministry of Labor approved for use against ozone. (3M 6000 Series half facepiece user instructions Table 7 footnote 1)
For P series filters only when used in environments containing oil aerosols: Dispose of P-Series filters after 40 hours of use or 30 days, whichever is first. (3M Cartridge and Filter Guide (brochure 70-0714-8870-7))

3M 2078 questions
What does the 3M 2078 protect against? The 3M chart lists P95. Nuisance-level relief and ozone notes are 3M recommendations, not NIOSH approvals, where the chart marks them.
Which 3M facepieces take the 2078? 3M bayonet facepieces: 6000 Series half (6100/6200/6300), 6500/6500QL Series, 7500 Series, 6000 Series full (6700/6800/6900), FF-400 Series, 7800S Series (3M Cartridge and Filter Summary (2024) row group "Bayonet-style 3M Reusable Respirators"; 3M 6500 Series spec sheet (2025) Approvals; 3M FF-400 Series specifications (US) Approvals; 3M Reusable Respirator Catalog (NIOSH) platform tables).
How does 3M pack the 2078? 100 EA/Case.
Does the 2078 have an end-of-service-life indicator? No end-of-service-life indicator is stated for this part in the documents fetched; 3M cartridge change schedules are set by the employer (3M 6000 Series half facepiece user instructions "Cartridge and Filter Replacement").
