Honeywell Saf-T-Fit Plus P100 Disposable Respirator (RWS-54020) — NIOSH-Approved P100 Disposable Respirator
An air-purifying respirator filters air, it does not supply any. Under 29 CFR 1910.134 no air-purifying respirator may be worn in an atmosphere that is IDLH or oxygen-deficient (below 19.5% oxygen). Those conditions require a supplied-air respirator or an SCBA, and no filter or cartridge rating changes that.
Honeywell Saf-T-Fit Plus P100 Disposable Respirator (RWS-54020) is Honeywell's Saf-T-Fit Plus P100 disposable respirator — providing NIOSH P100 oil-proof protection at 99.97% filtration efficiency with an exhalation valve for cooler wear during lead abatement, asbestos, heavy oil-mist, or other maximum-hazard applications where a disposable P100 is preferred over a reusable half-face.

High quality
I am very very very very sensitive to smoke; this feels like it provides a fairly good job of protection and comfort.

Five stars if you receive masks that are properly sealed!
I try to have at least a couple of these on hand in case of wildfires on the West Coast. I have a large face and the mask is comfortable on me and feels secure. I can definitely breathe better while wearing this compared to not wearing a mask when there is smoke and ash in the air. This mask offers more protection than an N95.Recently I ordered some masks and they were in some sort of clamshell plastic packaging. The packaging is open on almost all sides, and if the mask wasn't placed carefully into the packaging there was an even wider opening between the two pieces of plastic. I felt like the masks wouldn't work as well or for as long since the masks were exposed to open air, and I don't know how they were being stored or what they could have been exposed to. The next time I ordered masks they were in the packaging with a cardboard back and sealed plastic over the front -- I wish I knew which one I would be getting when I place my orders. (If you look at the photos from other reviews you can see the two different types of packaging.)These masks used to average about $10 - $11 each, but with the pandemic the price has increased to $17 - $18 each. It is a necessary purchase though if you live in California.

Didn't fit with my glasses
I have large glasses but not abnormally large. The mask pushed them up to the point they're unwearable. I can't figure out a way to wear them both so this mask doesn't work for me at all.

Solid mask
Very nice respirator. These are great because these are one of the few effective masks still available for public purchase. The elastic band is adjustable for your head size. Very easy to breath in. Very comfortable. They are a bit pricey, retail is around $12 and Amazon is now charging almost $18.I was a bit concerned about the reviews about the clamshell packaging, and them being "counterfeit". I called Honeywell customer support, they confirmed the mask numbers and clamshell packaging was legit.

Mask to end all masks
Yeah so the nice thing about this is if you remove the lower strap, it still seals against your face. Even if that seal is broken a little, it’s still probably better than a n95. I’m in South Korea and sick of the pollution. With this mask I can have the best filtration possible with a exhalation valve and the convenience of being able to take it off easily (if you take off the lower strap). I even was able to modify it to fit a microphone for my job. Primo 🤌

Great fit. Wish I could buy more
I wish I could buy more LOL I was smart enough to buy these early knowing that it would become very difficult to find a mask. They are very good. Sadly I had sprayed them with Lysol after several uses, only to find out that that reduces their effectiveness from and 99 to 29% filtration… Do not make my same mistake. Uses steam cleaner only, do not spray them with Lysol or bleach

★☆☆☆☆
Not same as pictured, UPC code over-labeled, huge:covered eyes and chin
My headline says most of it: this was unusable for me. Even without my glasses (impossible with) it covered part of my eyes and over my chin. I have a beard, the label should indicate: NOT FOR PEOPLE WITH BEARD OR GLASSES. But it doesn't, and since it is non-returnable under any circumstance, they do a good business on product that will not get used.Logical question: if airtight fit is essential on a mask, how can it possibly come in one-size-fits-all. It can't! and yet it does, but it doesn't, fit that is.And oh yeah: TWENTY DOLLARS just because they can get away with it, yet still no guarantee, no return?

Great 👍🏾
This is the most comfortable mask that I have bought thus far. I have bought several n95 and n100 masks throughout the pandemic. This one is my favorite. It's a little pricey for a single unit but it is worth it.

Frequently Asked Questions
What does the exhalation valve on the RWS-54020 Saf-T-Fit Plus do?
The exhalation valve opens when you breathe out, allowing warm humid air to exit directly rather than passing back through the filter media. This reduces heat and moisture buildup inside the mask — a significant comfort advantage during extended or physically demanding wear. Inhalation closes the valve, so all inhaled air is filtered normally.
Does the valve on the RWS-54020 Saf-T-Fit Plus reduce filtration efficiency?
No. The exhalation valve does not affect inhalation filtration efficiency — the RWS-54020 Saf-T-Fit Plus still filters inhaled air at the rated N95/R95/P100 level. The valve only controls exhaled air routing. Note: because exhaled air is not filtered, valved respirators are not appropriate as source-control devices (e.g., in surgical environments or when protecting others from the wearer).
Is a valved respirator like the RWS-54020 Saf-T-Fit Plus acceptable for source control?
No. A valved respirator directs exhaled air outward unfiltered and is not appropriate where the wearer must also protect others (surgical settings, some healthcare environments). Facility policies may prohibit valved masks in sterile or at-risk patient areas. For source-control requirements, use an unvalved N95 or a surgical N95.
What does P100 mean for the RWS-54020 Saf-T-Fit Plus?
P100 is the highest NIOSH particulate classification: ≥99.97% filtration efficiency, oil- proof (unlike R-series which is oil-resistant for one shift only). The RWS-54020 Saf-T-Fit Plus provides maximum particulate filtration with no time restriction on oil aerosol exposure. Compare classes in our N95 vs P100 guide .
Is the RWS-54020 Saf-T-Fit Plus NIOSH-approved?
Yes. The RWS-54020 Saf-T-Fit Plus holds NIOSH P100 approval under 42 CFR 84 Subpart K. Confirm the TC approval number on the NIOSH Certified Equipment List using the model number printed on the mask.
What hazards is the RWS-54020 Saf-T-Fit Plus rated for?
The RWS-54020 Saf-T-Fit Plus is rated for oil-proof particulates at ≥99.97% efficiency — covering lead dust, asbestos fibers, hexavalent chromium, heavy oil mist, paint overspray, and fine metallic particulates. Browse all P100 disposable respirators .
Does the RWS-54020 Saf-T-Fit Plus require a fit test?
Yes. OSHA 29 CFR 1910.134 requires fit testing before first use in any workplace respiratory protection program. See our fit testing guide for qualitative (BitrexTM/saccharin) and quantitative options for half-face disposable designs.
Can the RWS-54020 Saf-T-Fit Plus be used for lead abatement?
Yes, the P100 filter class is commonly specified for lead dust and paint chip abatement work. OSHA's lead standard (29 CFR 1910.1025) specifies a minimum APF 10 (half-face) for many lead operations. A properly fitting P100 disposable meets this requirement; verify with your site's industrial hygienist.
How long does the RWS-54020 Saf-T-Fit Plus last in oil mist environments?
Unlike the R95 class (one shift limit), the P100 class has no time restriction on oil aerosol exposure. Discard the RWS-54020 Saf-T-Fit Plus when breathing resistance increases noticeably, when the mask is damaged or soiled, or per your employer's change-schedule program.
Does the RWS-54020 Saf-T-Fit Plus filter vapors and gases?
No. The RWS-54020 Saf-T-Fit Plus is a particulate filter only — it does not capture organic vapors, acid gases, or other chemical vapors. For combined particulate + vapor protection, you need a half-face or full-face respirator with combination cartridges. See our respirator selection guide .
How does the RWS-54020 Saf-T-Fit Plus compare to N95 masks?
The RWS-54020 Saf-T-Fit Plus (P100) filters 99.97% of particles and is oil-proof; an N95 filters 95% and has no oil resistance. Step up to the RWS-54020 Saf-T-Fit Plus for lead, asbestos, heavy oil mist, or any application where an N95's 95% baseline isn't sufficient or where oil aerosols are present. Browse N95 masks for lighter-duty comparison.
Is the RWS-54020 Saf-T-Fit Plus reusable?
The RWS-54020 Saf-T-Fit Plus is a disposable respirator — discard after use per manufacturer guidance. Do not wash or attempt to decontaminate a disposable P100; the filter media and structural integrity cannot be verified after washing.
