Which Honeywell disposable respirator should you buy in 2026?

Short answer: The Honeywell DF300 N95 is the right choice for most general industrial buyers — a NIOSH-certified flat-fold N95 with a strong seal and low breathing resistance, available individually or as the H910P 20-pack for bulk procurement. For environments requiring P100 oil-proof filtration, the Honeywell SAF-T-FIT Plus P100 is the premium option in this lineup.

Honeywell Disposable Respirators (2026)

Honeywell is a global safety manufacturer with deep industrial roots, producing NIOSH-certified disposable respirators for construction, manufacturing, and general industrial use.

Buy the right Honeywell respirator — decision guide

• Buy Honeywell DF300 N95 for standard industrial N95 protection in dust, construction, and general manufacturing — flat-fold design fits easily in a pocket; broad nose bridge accommodates a wide range of face shapes.
• Buy H910P 20-pack if you're equipping a crew or running a safety program — same DF300 respirator at a lower per-unit cost in bulk packaging.
• Buy N95 RWS-54003 20-pack as a cost-optimized bulk N95 alternative when the H910P is out of stock or when your program requires this specific Honeywell item number.
• Buy SAF-T-FIT Plus P100 when your application requires oil-proof 99.97% filtration — lead abatement, silica at high concentrations, heavy oil-mist machining, asbestos removal, or any task where P100 is specified by your written respiratory protection program. See also our P100 disposable collection for cross-brand comparison.

How to choose a Honeywell disposable respirator

DF300 vs H910P — what is the difference?

The Honeywell DF300 and H910P DF300 are the same respirator. The H910P is the model number used for the 20-pack bulk packaging of the DF300 flat-fold N95. Individual purchase uses the DF300 designation; bulk box procurement uses the H910P item number. Both provide identical NIOSH N95 protection — the choice is purely quantity and price-per-unit. For safety programs issuing respirators regularly to workers, the H910P 20-pack delivers lower per-unit cost.

How does Honeywell N95 compare to 3M and Moldex?

All NIOSH N95 respirators from any manufacturer meet the same minimum 95% filtration standard — the certification is not brand-dependent. Practical differences between brands are comfort, fit profile, and breathing resistance. The Honeywell DF300 flat-fold is a known quantity in industrial settings and has been through OSHA-required fit-testing programs across diverse worker populations. For cross-brand comparison, see our N95 buyer's guide and all N95 respirators. Fit test results for individual workers — not brand loyalty — should drive model selection under 29 CFR 1910.134.

When to choose P100 (SAF-T-FIT Plus) over N95 (DF300)

The SAF-T-FIT Plus P100 provides oil-proof 99.97% filtration — use it when your application requires: (1) the P oil-proof class (machining with cutting fluid mist, oil-based spray processes), (2) maximum filtration (lead abatement, crystalline silica at high concentrations, asbestos work, beryllium), or (3) when your written respiratory protection program specifies P100 for the task. For standard industrial dust, construction, and general manufacturing where oil mist is not present and the hazard concentration is within N95's protection margin, the DF300 N95 is adequate and significantly more cost-effective per use. See our P100 vs N95 guide for the full selection framework.

Fit testing Honeywell respirators under OSHA 1910.134

Any negative-pressure respirator required by OSHA — including Honeywell disposables — must pass a qualitative or quantitative fit test before first use and annually thereafter under 29 CFR 1910.134(f). Honeywell respirators are listed on the NIOSH NPPTL Certified Equipment List with their TC-approval numbers. Confirm the TC number on packaging matches the CEL entry before deploying in a required-use program. See our fit testing guide for the OSHA protocol.

NIOSH certification and compliance

All Honeywell disposable respirators in this collection are NIOSH-certified under 42 CFR Part 84. TC-approval numbers are printed on the respirator packaging and can be verified on the NIOSH Certified Equipment List. The P100 SAF-T-FIT Plus meets 42 CFR Part 84 Subpart K requirements for P100 class respirators (oil-proof, ≥99.97% efficiency). Under OSHA 29 CFR 1910.134, all N95 and P100 class filtering facepiece respirators carry an APF of 10, appropriate for exposures up to 10× the OSHA PEL for the relevant substance. Consult your respiratory protection program or a CIH for substance-specific selection.

Honeywell Disposable Respirator FAQ

Is the Honeywell DF300 NIOSH-approved?

Yes. The Honeywell DF300 N95 flat-fold respirator is NIOSH-certified under 42 CFR Part 84 for N95 class filtration (≥95% efficiency against 0.3-micron particles). The TC-approval number is printed on the respirator and packaging and can be verified on the NIOSH NPPTL Certified Equipment List.

What is the difference between Honeywell DF300 and H910P?

They are the same respirator. The H910P is the Honeywell item number for the 20-pack bulk box of DF300 flat-fold N95 respirators. Individual units are sold as DF300; the 20-unit bulk box is sold as H910P. Protection, certification, and fit are identical.

Honeywell DF300 vs 3M 8210 — which N95 is better?

Both are NIOSH-certified N95 respirators meeting the same minimum 95% filtration standard. The 3M 8210 is a cup-style respirator while the Honeywell DF300 is a flat-fold design — the practical difference is fit profile and storage compactness. Neither is universally "better"; fit test results for each individual worker under OSHA 1910.134 should determine the model used. Both are appropriate for general industrial, construction, and dust-exposure applications where N95 is required.

What does SAF-T-FIT Plus P100 protect against?

The Honeywell SAF-T-FIT Plus P100 provides oil-proof 99.97% filtration against solid and liquid oil-based particulate aerosols. It is appropriate for lead, silica, asbestos, beryllium, cadmium, radioactive dust, heavy oil-mist machining, and any application where P100 filtration is specified. As a filtering facepiece, it carries an OSHA APF of 10 — appropriate for concentrations up to 10× the OSHA PEL.

Are Honeywell disposable respirators made in the USA?

Honeywell manufactures safety products at facilities worldwide. Not all Honeywell disposable respirators are US-made — verify country of origin on the product packaging. For programs that require domestic manufacture, Gerson and Moldex are US-based manufacturers; see Gerson disposable respirators and Moldex disposable respirators.

Can I reuse Honeywell N95 respirators?

Honeywell N95 disposables are designed for single-use. Reuse is not recommended in the manufacturer's standard guidance. Under certain emergency supply conditions, the CDC and NIOSH have issued limited reuse protocols — but these apply to verified shortage scenarios, not routine use. Discard when soiled, damaged, breathing resistance increases, or after each high-risk exposure event. See our N95 reuse guide for the complete protocol.

Does Honeywell make a valved N95 disposable respirator?

The Honeywell disposable respirators in this collection are unvalved (no exhalation valve). Valved N95 disposables are available from other brands — see the SAS Safety 8611 and Moldex valved N95 options in our N95 collection if an exhalation valve is required for your program.

What is the APF for Honeywell P100 and N95 disposables?

OSHA assigns an APF of 10 to all filtering facepiece respirators (N95, P100 disposables, and similar half-mask types) under 29 CFR 1910.134. This applies regardless of filter efficiency — the APF reflects the facepiece seal class, not the filter. For concentrations requiring APF above 10, a full-face respirator (APF 50) or supplied-air system is required.
