3M 60927 Mercury Vapor P100 Cartridge Overview

What It Protects Against

This cartridge protects within limits. The end-of-service-life indicator is a real advantage for mercury, but it signals mercury saturation only — it does not indicate organic-vapor or acid-gas breakthrough, so you still follow a written change schedule for those and change on odor, taste, or irritation, and within 50 hours of mercury exposure. It removes only the gases it is rated for and adds no oxygen, so it does not cover ammonia or formaldehyde, and no air-purifying respirator may be used in an oxygen-deficient atmosphere or one that is immediately dangerous to life or health (IDLH) — those require a supplied-air respirator or a self-contained breathing apparatus (SCBA). It works only on a fit-tested, clean-shaven seal on a 3M-approved facepiece within an OSHA 29 CFR 1910.134 program, in matched pairs. See best acid-gas cartridge and best 3M multi-gas cartridge.

Frequently Asked Questions

What does the 3M 60927 protect against?

It is NIOSH-approved against mercury vapor, chlorine, sulfur dioxide, organic vapor, and hydrogen sulfide, plus particulate through its P100 filter. Match your specific contaminants to the cartridge's rated classes and your safety data sheets before use.

What is the ESLI, and what does it indicate?

The 60927 has a passive end-of-service-life indicator (ESLI) that changes color as the mercury sorbent loads, giving you a visual cue that mercury vapor is reaching saturation. It is a helpful backup to, not a replacement for, a written change schedule.

Does the ESLI cover all the gases, or just mercury?

Just mercury. The color-change ESLI indicates mercury vapor saturation only. It does not indicate breakthrough of organic vapor or acid gases, so you still follow a written change schedule for those, and change on odor, taste, or irritation.

How long can I use it for mercury vapor?

3M says to change the cartridge within 50 hours of mercury vapor exposure, in line with your documented change schedule, or sooner if the ESLI signals saturation or you detect contaminants. Do not exceed the 50-hour mercury limit.

Does the 60927 cover ammonia or formaldehyde?

No. Its rated classes are mercury vapor, chlorine, sulfur dioxide, organic vapor, and hydrogen sulfide. Ammonia and formaldehyde are different hazards; for a broad multi-gas range, look at the 3M 60926 instead, matched to your specific gases.

Does it filter particles as well as gases?

Yes. It is a combination cartridge: the gas and vapor sorbent is paired with a P100 particulate filter that captures at least 99.97% of airborne particles. That suits mercury and chemical work that also produces dust or mist.

Which facepieces does the 60927 fit?

It uses the 3M bayonet connection and fits the 3M 6000, 6500, and 7500 series half facepieces and the 6000, FF-400, and 7800 series full facepieces. It does not fit other brands or 3M's Secure Click platform.

Do I use one cartridge or a pair?

Cartridges are used in pairs, one on each side of a 3M bayonet facepiece, and are sold that way. Change them as a matched pair; a single or mismatched pair is not an approved configuration and compromises protection.

Can the 60927 be used in a confined space or low-oxygen air?

No. A cartridge removes only specific gases and adds no oxygen. A confined space or a low-oxygen or immediately hazardous atmosphere needs a supplied-air system or a self-contained breathing apparatus, plus entry procedures, not an air-purifying cartridge.

What industries use the 60927?

It suits work with mercury vapor and the listed acid gases and organic vapors, such as mercury reclamation and spill cleanup, dental and lab work, chlor-alkali, and instrument servicing. Confirm your specific exposures fall within its rated classes.

Are 3M cartridges interchangeable with other brands?

No. Respirator cartridges are brand- and platform-specific. The 60927 fits only 3M bayonet facepieces, not Honeywell, Moldex, or other brands. Using the wrong cartridge voids the NIOSH approval and the protection it provides.

How should I store the cartridges?

Keep unopened cartridges sealed in a clean, dry place within their rated conditions, and do not use one past its shelf life. Once in service a cartridge begins to load, so note when you install it and track it against your change schedule and the ESLI.
