Honeywell 7580P100 vs 3M 2091: Cross-Brand P100 Filter Compared
Same P100 Rating. Different Brand Mount. These Two Filters Are Not Interchangeable.
Reviewed by WC Safety Editorial Team — Last updated: May 2026.
Short answer: The Honeywell North 7580P100 and 3M 2091 are functionally equivalent P100 filters — both rated at 99.97% particulate efficiency, both oil-resistant. The critical difference: they use different brand-specific mounts. The 7580P100 fits Honeywell North 7700 and 5500 series facepieces. The 3M 2091 fits 3M 6000, 6500, and 7500 series facepieces. You cannot mix brands. Choose the filter that matches your existing facepiece system.
Critical Note: Honeywell North and 3M cartridge systems are NOT cross-compatible. Never force a Honeywell cartridge onto a 3M facepiece or vice versa — improper fit defeats the respirator's seal and provides no protection. Check the Honeywell North Cartridge Guide and 3M Filter & Cartridge Guide for the correct filter for your facepiece.

Which System to Choose
If you're starting from scratch, the choice between Honeywell North and 3M comes down to facepiece fit and your site's existing inventory. Both brands offer equivalent P100 protection. The Honeywell North 5500 series (silicone) is comparable to the 3M 7500 series. The Honeywell North 7700 series is comparable to the 3M 6000 series. Fit testing determines which brand and model works for each individual. See the best half face respirator rankings for a cross-brand overview.

Frequently Asked Questions
Can I use a Honeywell 7580P100 filter on a 3M respirator?
No. The Honeywell North 7580P100 uses Honeywell's proprietary mount and is designed for Honeywell North 7700 and 5500 series half masks only. It is not compatible with 3M facepieces, and 3M 2091 filters only fit 3M facepieces.
What is the filtration efficiency of the Honeywell 7580P100?
NIOSH P100 — at least 99.97% against oil-based and non-oil-based particulates. Same efficiency class as the 3M 2091.
Which half masks fit the Honeywell 7580P100?
The Honeywell North 7700 series (standard rubber) and 5500 series (silicone facepiece) half masks. It is not compatible with 3M facepieces or other brands.
What chemical protection do Honeywell 7580P100 and 3M 2091 provide?
Neither provides chemical or gas protection — both are pure P100 particulate filters. For OV protection, upgrade to Honeywell 7582P100L (OV/P100) or 3M 60921 (OV/P100) combination cartridges.
Which is better: Honeywell 7580P100 or 3M 2091?
Both are identical in protection at 99.97% P100. Choose based on which brand facepiece you have. If you own a Honeywell North 7700 or 5500, use the 7580P100. If you own a 3M 6000/6500/7500, use the 3M 2091.
Can the Honeywell 7580P100 be used for asbestos abatement?
Yes. As a NIOSH P100 filter, it provides HEPA-equivalent filtration meeting OSHA 29 CFR 1910.1001 requirements when used with a properly fit-tested Honeywell North half mask.
How do I know if my respirator uses Honeywell or 3M cartridges?
Check the brand name on your facepiece. Honeywell North 7700 and 5500 facepieces use Honeywell North cartridges. 3M 6000/6500/7500 facepieces use 3M cartridges. Mount systems are brand-specific.
Does Honeywell make a version of the 7580P100 with organic vapor protection?
Yes. The Honeywell North 7582P100L adds organic vapor protection to P100 filtration, and the 7583P100L further adds acid gas protection. For pure P100 particulate protection only, the 7580P100 is correct.
Are Honeywell North and 3M P100 filters equivalent in protection?
Yes. All NIOSH P100-approved filters must meet the same 99.97% efficiency standard regardless of brand. The difference is in facepiece compatibility, not protection level.
How long does the Honeywell 7580P100 last?
Replace when breathing resistance increases, when physically damaged, or per your site's change-out schedule. Follow OSHA 29 CFR 1910.134 change-out requirements.
What NIOSH approval does the Honeywell 7580P100 hold?
NIOSH TC-84A approval for P100 particulate filtration. The NIOSH approval number is printed on the filter body — always verify before use.
What Honeywell North half mask should I pair with the 7580P100?
The 7580P100 is compatible with Honeywell North 7700 series and 5500 series half masks. The 5500 series (silicone) is Honeywell's equivalent to the 3M 7500 series for all-day comfort wear.
