Priced at $21.19 per pair, the 7740 is the baseline choice when particulate control — dust, fumes, mists, metal particulates, and biological aerosols — is the only hazard on the job.

The Moldex 7740 belongs in the \"particulate-only\" column of any hazard assessment. If your air monitoring confirms airborne dust, fumes, mists, radionuclides, or biological aerosols with no gas or vapor co-exposure, the 7740 is the correct choice for a Moldex platform. If gases or vapors are also detected, a combination cartridge is mandatory.\u003c\/p\u003e\n\n\u003cp\u003eUnderstanding filter efficiency ratings is foundational: P100 is the highest NIOSH particulate rating, requiring filtration of at least 99.97% of particles at 0.3 microns — the most penetrating particle size — and the \"P\" designation confirms oil-proof resistance, making the 7740 suitable for mist environments as well as dry dust.

Cross-brand mounting is not NIOSH-approved and compromises the protection factor.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eHow many filters come in one pack of Moldex 7740?\u003c\/h3\u003e\n\u003cp\u003eThe Moldex 7740 is sold as a pair — two filters per bag — at $21.19. Both filters are required for proper two-sided mounting on Moldex half-mask and full-face respirators.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eDoes the Moldex 7740 have an ESLI (End-of-Service-Life Indicator)?\u003c\/h3\u003e\n\u003cp\u003eNo. The Moldex 7740 does not include an ESLI. Because particulate filters do not deplete by chemical adsorption, change interval for P100 filters is typically based on breathing resistance (replace when it becomes difficult to breathe through) or a time-based change schedule required under OSHA 29 CFR 1910.134 when no ESLI is present.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eWhat is the difference between the Moldex 7740 and the 7740+?\u003c\/h3\u003e\n\u003cp\u003eThe Moldex 7740+ adds IonicAir electrostatic-assist technology to the same NIOSH P100 mechanical filter base as the 7740. Both are priced at $21.19 per pair and share identical respirator compatibility. The 7740+ is designed to maintain lower breathing resistance over the filter's working life compared to the standard 7740.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eCan the Moldex 7740 be used for asbestos or lead abatement?\u003c\/h3\u003e\n\u003cp\u003eYes. OSHA regulations for lead (29 CFR 1926.62) and asbestos (29 CFR 1926.1101) permit or require P100 filters for specific exposure levels. The Moldex 7740's NIOSH P100 certification meets this filter class requirement when mounted on a properly fit-tested Moldex 7000 or 9000 series respirator and used within an employer-maintained respiratory protection program.\u003c\/p\u003e\n\n\u003c!-- [12] SPECIFICATIONS --\u003e\n\u003ch2 style=\"color:#ff9800\"\u003eMoldex 7740 Specifications\u003c\/h2\u003e\n\u003ctable

style=\"color:#ff9800\"\u003eMoldex 7740 Frequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eIs the Moldex 7740 NIOSH approved?\u003c\/h3\u003e\n\u003cp\u003eYes. The Moldex 7740 carries NIOSH approval under 42 CFR Part 84 as a P100 particulate filter, confirming filtration efficiency of at least 99.97% for both oil and non-oil aerosols at the most penetrating particle size (approximately 0.3 microns).\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eCan I use the Moldex 7740 for silica dust exposure?\u003c\/h3\u003e\n\u003cp\u003eYes, provided the respirator and filter combination is part of a compliant written respiratory protection program that includes fit testing. OSHA's respirable crystalline silica rules (29 CFR 1910.1053 and 1926.1153) specify minimum filter classes by task; P100 meets or exceeds the class requirement for all silica-exposure tasks listed in OSHA Table 1 where a respirator is required.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eHow long does a Moldex 7740 filter last before replacement?\u003c\/h3\u003e\n\u003cp\u003eMoldex 7740 filters do not have an ESLI. Replace when breathing resistance increases noticeably — a physical indication that the filter media is loaded — or according to your employer's written change schedule established under OSHA 29 CFR 1910.134(d)(3)(iii). In heavy-dust environments, service life may be as short as one shift; in light-particulate environments, a pair may last several weeks.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eDoes the Moldex 7740 work on the Moldex 9000 full-face respirator?\u003c\/h3\u003e\n\u003cp\u003eYes. The Moldex 7740 is fully compatible with the Moldex 9000 series full-face respirator (models 9001, 9002, 9003). Using a full-face respirator with the 7740 also provides integrated eye and face protection, which is valuable in high-dust or abrasive particulate environments.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eWhat is the difference between the 7740 and 7367 combo cartridge?\u003c\/h3\u003e\n\u003cp\u003eThe Moldex 7740 filters particulate only — it provides no gas or vapor protection. The 7367 is a combination cartridge that provides P100 particulate filtration plus organic vapor and acid gas protection. If your job involves both particles and chemical vapors or gases, the 7367 is the correct choice. The 7740 should only be selected when a confirmed particulate-only hazard is present.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eCan the Moldex 7740 be worn with a beard?\u003c\/h3\u003e\n\u003cp\u003eNo air-purifying tight-fitting respirator provides adequate protection when facial hair breaks the facepiece seal. OSHA prohibits the use of tight-fitting respirators when facial hair contacts the sealing surface. The Moldex 7000 and 9000 series respirators that carry the 7740 are both tight-fitting and subject to this requirement.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eIs the Moldex 7740 suitable for spray painting?\u003c\/h3\u003e\n\u003cp\u003eOnly if the spray application involves exclusively non-toxic water-based paints or coatings with no solvent content above nuisance levels and no isocyanate hazards. Standard spray painting with solvent-based paints, lacquers, or polyurethane coatings requires an OV-rated or OV\/AG-rated cartridge — not a particulate-only filter. The 7367 OV\/AG\/P100 combination or the 7667 Multi-Gas\/P100 smart combo are more appropriate for spray finishing work.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eHow do I know when to replace the Moldex 7740 filter?\u003c\/h3\u003e\n\u003cp\u003eReplace the Moldex 7740 when breathing through the respirator becomes noticeably harder — increased breathing resistance indicates the filter is loaded with captured particles. If the filter becomes physically damaged, wet, or contaminated, replace it immediately. Your employer's written respiratory protection program must include a change schedule that accounts for exposure levels, shift duration, and task-specific dust generation rates.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eDoes the Moldex 7740 protect against mold spores?\u003c\/h3\u003e\n\u003cp\u003eYes. Mold spores are biological aerosol particles in the 1–30 micron size range. The 7740's P100 filter captures particles at ≥99.97% efficiency, well above the size of mold spores. For mold remediation work, confirm whether your program requires a half-mask or full-face respirator based on remediation area size and mold type per industry guidelines (e.g., EPA mold remediation guidelines or IICRC S520).\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eWhat is the Moldex 7740 color code?\u003c\/h3\u003e\n\u003cp\u003eNIOSH color-coding for P100 filters is magenta (purple-pink). The Moldex 7740 is color-coded per NIOSH standards to allow at-a-glance identification. Magenta indicates P100 particulate filtration — no gas or vapor protection is implied by this color designation.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eCan I purchase Moldex 7740 filters individually instead of as a pair?\u003c\/h3\u003e\n\u003cp\u003eThe Moldex 7740 is sold as a pair only at WC Safety ($21.19 for 2 filters). Moldex does not offer the 7740 in a single-filter purchase format. If you need a single-unit P100 filter with nuisance OV\/AG relief, the 7760 ($5.31\/single) is available separately, though it is a different product with different protection characteristics.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d\"\u003eIs the Moldex 7740 appropriate for lead paint removal?\u003c\/h3\u003e\n\u003cp\u003eYes, subject to OSHA 29 CFR 1926.62 requirements. At lead air concentrations at or above the action level (30 μg\/m³ as an 8-hour TWA), a half-face air-purifying respirator with P100 filters is required. At concentrations above 10 times the PEL (500 μg\/m³ TWA) or in IDLH conditions, a powered air-purifying respirator (PAPR) or higher level of protection is required. The 7740 meets the P100 filter class for qualifying lead abatement tasks.\u003c\/p\u003e\n\n\u003c!-- [15] FOOTER E-E-A-T TRUST BLOCK --\u003e\n\u003cdiv style=\"border-top:1px solid #333;margin-top:32px;padding-top:16px;font-size:0.85em;color:#888;\"\u003e\n  \u003cp\u003eWritten by \u003cstrong\u003eSteven Eaton\u003c\/strong\u003e, WC Safety Editorial — Industrial hygiene \u0026amp; PPE specialist, 10+ years respiratory protection sourcing.\u003c\/p\u003e\n  \u003cp\u003eReviewed by the WC Safety Editorial Team.
