The NIOSH N95 designation certifies that the respirator filters ≥95% of test aerosol particles at 0.3 microns under standard test conditions — the particle size at which filtration mechanisms are least efficient, making N95 the minimum threshold for meaningful aerosol protection. The DF300 DF300 meets this threshold through electrostatic and mechanical filtration in the filter media, combining charge-based attraction with size exclusion to capture sub-micron particles that would pass through a simple mechanical barrier.\u003c\/p\u003e\n\n\u003cp\u003eThe facial seal is the critical performance variable for disposable N95 respirators. A respirator with 95%+ filter efficiency provides no useful protection if it does not seal against the face — contaminant-laden air simply bypasses the filter through face seal leakage. The DF300 uses a deployable flat-fold shell that maintains the respirator's three-dimensional shape against the face, preventing the filter collapse against the mouth and nose that occurs with improperly designed cup structures. The adjustable nose wire customizes the fit to individual nasal bridge geometry, and the foam nose cushion provides both comfort and secondary sealing at the most common leakage point.\u003c\/p\u003e\n\n\u003cp\u003eThe DF300 is designed without an exhalation valve, maintaining filter integrity for both inhalation and exhalation airflow. This is the appropriate configuration for source control applications and environments where protection of others from the wearer exhaled air protection is required in addition to worker protection.\u003c\/p\u003e\n\n\u003cp\u003eThe flat-fold design of the DF300 allows compact packaging and storage in quantities that cup-style respirators cannot match. Workers can carry several flat-fold respirators in a work vest pocket without the bulk associated with rigid cup respirators, ensuring access to fresh respirators throughout a shift without requiring trips to a supply station.\u003c\/p\u003e\n\n\u003ch2\u003eApplications and Use Cases\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eConstruction — silica dust from concrete cutting, grinding, and masonry work\u003c\/li\u003e\n  \u003cli\u003eWelding and metal fabrication — welding fume and metal dust protection (verify compatibility with specific fumes)\u003c\/li\u003e\n  \u003cli\u003eHealthcare support — hospital and clinic environmental services work\u003c\/li\u003e\n  \u003cli\u003ePharmaceutical manufacturing — API dust and particulate protection in production areas\u003c\/li\u003e\n  \u003cli\u003eWoodworking — fine wood dust protection below the 5 mg\/m³ OSHA PEL\u003c\/li\u003e\n  \u003cli\u003eJanitorial and facility maintenance — general particulate protection for cleaning operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable border=\"1\" cellpadding=\"6\" cellspacing=\"0\" style=\"border-collapse:collapse;width:100%;\"\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eDF300\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProduct ID\u003c\/td\u003e\n\u003ctd\u003e8727069720664\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eDisposable N95 Respirator\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFiltration\u003c\/td\u003e\n\u003ctd\u003e≥95% Non-Oil-Based Particulates (N95)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eExhalation Valve\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStyle\u003c\/td\u003e\n\u003ctd\u003eFlat-Fold\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eNose Strip\u003c\/td\u003e\n\u003ctd\u003eAdjustable Nose Wire + Foam Cushion\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eApproval\u003c\/td\u003e\n\u003ctd\u003eNIOSH N95 (TC-84A approved)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSold As\u003c\/td\u003e\n\u003ctd\u003eBox (quantity per product listing)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eRelated Products\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/wcsafety.com\/collections\/disposable-respirators\"\u003eRespirators — Full Collection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/safety-glasses\"\u003eSafety Glasses — Eye Protection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/hearing-protection\"\u003eHearing Protection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/wcsafety.com\/collections\/hand-protection\"\u003eWork Gloves — Hand Protection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/hard-hats\"\u003eHard Hats — Head Protection\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdl\u003e\n  \u003cdt\u003eWhat does NIOSH N95 certification mean?\u003c\/dt\u003e\n  \u003cdd\u003eThe respirator is independently tested and verified to filter ≥95% of airborne particles at 0.3 microns. The NIOSH TC number on the packaging confirms this verification. N95 is the minimum OSHA-accepted level for silica, metal fume, and biological particulate protection.\u003c\/dd\u003e\n\n  \u003cdt\u003eDoes the DF300 require fit testing?\u003c\/dt\u003e\n  \u003cdd\u003eYes. OSHA 29 CFR 1910.134 requires annual fit testing when respiratory protection is required as part of a workplace program. Fit test with the specific DF300 model the worker will actually use.\u003c\/dd\u003e\n\n  \u003cdt\u003eHow long before replacement?\u003c\/dt\u003e\n  \u003cdd\u003eReplace when breathing resistance increases, when wetted or oil-contaminated, or when the face seal is compromised. Single-use or limited-use only — do not reuse beyond manufacturer guidance.\u003c\/dd\u003e\n\n  \u003cdt\u003eIs the DF300 appropriate for oil mist?\u003c\/dt\u003e\n  \u003cdd\u003eNo. N-series (N95) filters degrade with oil aerosol exposure.
