Designed for the most demanding industrial particulate applications, the 2280 combines a full foam inner gasket, heavy-duty adjustable head straps, premium oversized exhalation valve, and flame-retardant outer shell in a single disposable SKU. Each box contains 5 respirators.\u003c\/p\u003e\n\n\u003ch2\u003eConstruction and Materials\u003c\/h2\u003e\n\u003cp\u003eThe 2280 uses a heavy-duty molded cup design with a flame-retardant outer shell. The full foam inner gasket provides a continuous peripheral seal around the entire face contact area, accommodating facial profiles and movement patterns that a standard hard-molded edge may not seal consistently. Heavy-duty adjustable head straps fit a broad range of head sizes and exert even tension across the face. The premium oversized exhalation valve expels warm, humid exhaled air at lower opening resistance than standard valves. Internal filter media maintains its rated efficiency through the P-series wear cycle.\u003c\/p\u003e\n\n\u003ch2\u003eCompliance and Ratings\u003c\/h2\u003e\n\u003cp\u003eNIOSH approved under 42 CFR Part 84. P100 designation certifies ≥99.97% filtration efficiency against solid and liquid aerosols, including oil-based aerosols, with P-series (unlimited) approval for oil mist environments. P-series approval removes the time-limitation constraint of R-series respirators in oil environments. The 2280 is appropriate for OSHA PEL-driven respiratory protection programs where hazard assessment identifies elevated oil-mist or high-concentration particulate exposure levels.\u003c\/p\u003e\n\n\u003ch2\u003ePerformance\u003c\/h2\u003e\n\u003cp\u003eAt 99.97% filtration efficiency, the 2280 is the highest-performance disposable particulate respirator in Gerson's line. The full foam gasket delivers a measurably superior peripheral seal compared to standard molded cup edges, which is particularly important in P100 applications where the assigned protection factor of 10 requires reliable fit across the workforce. The oversized valve and flame-retardant shell address the thermal and comfort demands of sustained industrial wear in foundry, refinery, and heavy manufacturing environments.\u003c\/p\u003e\n\n\u003ch2\u003eStrengths\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/blogs\/guides\/n95-vs-kn95-vs-p100-which-respirator-do-you-actually-need\" style=\"color:#4fc3f7;\"\u003eP100 NIOSH certification — ≥99.97% filtration, oil aerosol unlimited-duration approval\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eFull foam inner gasket provides superior peripheral seal over varied facial profiles\u003c\/li\u003e\n  \u003cli\u003eFlame-retardant outer shell for hot-work environments\u003c\/li\u003e\n  \u003cli\u003ePremium oversized exhalation valve reduces heat and moisture buildup\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty adjustable straps provide consistent fit across a broad workforce\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eLimitations\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e5-per-box format carries a higher per-unit cost than case purchasing\u003c\/li\u003e\n  \u003cli\u003eExhalation valve means exhaled air is unfiltered — not suitable for source control applications\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/blogs\/guides\/n95-vs-kn95-vs-p100-which-respirator-do-you-actually-need\" style=\"color:#4fc3f7;\"\u003eAt the disposable P100 tier, the cost per unit approaches that of reusable half-mask respirators with replaceable P100 cartridges for high-volume users\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eRecommended Use Cases\u003c\/h2\u003e\n\u003cp\u003eThe 2280 is the appropriate choice for the most demanding particulate applications: lead abatement, isocyanate environments (where P100 is specifically required by OSHA), petroleum refinery operations, foundry pours, asbestos abatement, and high-concentration metallic fume environments.

N95 provides ≥95% against non-oil particles only. R95 provides ≥95% against all aerosols including oil, but with a time-limited (not unlimited) approval for oil environments. P100 represents the highest filtration efficiency and broadest oil-exposure approval in the NIOSH filter classification system.\u003c\/p\u003e\n\n\u003ch3\u003eDoes OSHA require P100 for specific operations?\u003c\/h3\u003e\n\u003cp\u003eYes. OSHA specifically requires P100 or equivalent for certain isocyanate operations (29 CFR 1910.1000 Table Z-1), for lead exposure above the action level in certain conditions, and for other regulated substances. Confirm the specific OSHA standard applicable to the operation before specifying the respirator class.\u003c\/p\u003e\n\n\u003ch3\u003eHow many 2280 respirators are in a case?\u003c\/h3\u003e\n\u003cp\u003eEach box contains 5 respirators. A standard case contains 10 boxes (50 units total).\u003c\/p\u003e\n\n\u003ch3\u003eIs the Gerson 2280 appropriate for spray painting?\u003c\/h3\u003e\n\u003cp\u003eThe 2280 addresses the particulate component of spray painting — aerosol droplets and paint mist. However, solvent vapors from lacquers, enamels, and urethanes require organic vapor cartridges that the 2280 does not provide. A combination OV\/P100 half-mask respirator is the standard specification for spray painting operations. The 2280 is appropriate for paint sanding and dust removal where vapor exposure is not present.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the valve's function on the Gerson 2280?\u003c\/h3\u003e\n\u003cp\u003eThe premium oversized exhalation valve opens at lower pressure than standard valve designs, expelling warm, humid exhaled air through an unfiltered path. This reduces the heat and moisture accumulation inside the mask during sustained wear. Because exhaled air bypasses the filter, the 2280 is not appropriate for source-control applications.\u003c\/p\u003e","brand":"Gerson","offers":[{"title":"Box of 5","offer_id":44064887504984,"sku":"082280","price":35.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/1900\/0920\/files\/Gerson-2280pix-022814c.jpg?v=1777881838","url":"https:\/\/wcsafety.com\/products\/gerson-2280-p100-particulate-respirator-box-5","provider":"WC Safety","version":"1.0","type":"link"}
