A rugged silicone face seal and 3M Cool Flow™ valve make this 3M half face respirator comfortable for long days, and it twist-locks onto the full 3M bayonet cartridge and filter library.

Honest Limits

The boundaries matter more here than in most PPE: a tight-fitting respirator protects only after a fit test and a user seal check, cartridges and filters expire on schedules rather than on smell, and nothing in this class is for IDLH atmospheres or oxygen deficiency.

Primary sources for this page

The wording behind this page sits in OSHA 29 CFR 1910.134, NIOSH Certified Equipment List, OSHA 29 CFR 1910.132.

Why trust this page?

Why trust this page? Every figure on it is taken from the published text of the standard or the manufacturer document named beside it, not from a secondary summary. WC Safety is an independent PPE review site: we hold no inventory and sell nothing directly, so there is no product we need this page to favour. Where sources disagree, the page says so and plans on the more conservative figure rather than picking one.

Methodology: how this page is maintained

Methodology. Figures are read from the primary source and re-checked whenever the underlying standard or a manufacturer document changes. No laboratory testing is performed for this page. Where a figure is not published, the page states that rather than estimating it, because a plausible invented number is more dangerous than an absent one.
