EDITORIAL REVIEW: 4.5/5WC Safety Review — MSA Advantage N95 Cover
Best For: crews running N95 prefilter discs on MSA Advantage cartridges who want a reusable holder.
Not For: anyone needing the actual filter or gas protection — the cover holds discs, it does not filter.
Bottom Line: the reusable holder for N95 prefilter discs on the MSA Advantage system; buy it with the discs and your gas cartridge.

MSA Advantage N95 Cover Overview
The MSA Advantage N95 Cover is a reusable snap-on cover for the MSA Advantage system. It secures N95 prefilter discs against an Advantage cartridge, so you replace the inexpensive discs and keep the cover. Start with our filter types explained guide and confirm your system in Comfo vs Advantage; the cover only fits Advantage facepieces.
As an MSA Advantage accessory the MSA Advantage N95 Cover belongs to the MSA respirator filters and cartridges range. Pair it with N95 prefilter discs and an Advantage gas cartridge such as the Advantage GMA.
Where the MSA Advantage N95 Cover Fits
The MSA Advantage N95 Cover is a holder, not a filter. It carries the N95 disc in front of a gas cartridge so dust is captured before it loads the cartridge. For a built-in particulate option instead, the Advantage GMA/P100 cartridge needs no cover.
What the Cover Does & Does Not Do
| Hazard | Fit | Buyer guidance |
|---|---|---|
| Holds a N95 prefilter disc | Yes | Reusable; discs change underneath. |
| Captures particulate by itself | No | The disc is the filter media. |
| Protects against gases | No | Use an MSA Advantage gas cartridge. |
What the Cover Does NOT Replace
The MSA Advantage N95 Cover is not a respirator, filter or cartridge. You still need N95 prefilter discs and a gas cartridge or P100 filter for the actual protection; for a full particulate filter see the Advantage P100 filter.
No air-purifying cartridge makes a dangerous atmosphere safe. Never use the MSA Advantage N95 Cover in an oxygen-deficient or IDLH (immediately dangerous to life or health) atmosphere, in unknown concentrations, or against gases with no warning properties — those conditions require a supplied-air or SCBA system, not a cartridge respirator. A cartridge or filter carries no assigned protection factor of its own — the APF comes from the facepiece it is fitted to: 10 for a half mask, 50 for a full facepiece (OSHA 1910.134 Table 1), which is the number that decides the highest exposure the respirator may legally be worn in. That facepiece must be fit tested before first use and at least annually, and a fit test is specific to one make, model, and size — passing on one mask does not carry over to another. Perform a user seal check every time the respirator is donned, and note that facial hair crossing the sealing surface disqualifies a tight-fitting respirator no matter how well it fit at the last test.
Best Applications
Crews running prefilter discs
Where dusty work loads prefilters fast, a reusable cover plus cheap N95 discs is the lowest-cost way to keep cartridges clean.
Pairing with an Advantage gas cartridge
Snap the cover with a disc onto an Advantage cartridge such as the Advantage GMB acid gas to add particulate protection.

MSA Advantage N95 Cover vs Other MSA Particulate Options
| Cartridge | Protects against |
|---|---|
| Advantage N95 disc | Filter media (consumable) |
| Advantage P100 filter | Full P100 filter |
| Advantage GMA/P100 | OV + P100 combo |
MSA Advantage N95 Cover vs the Alternatives
How it compares to the closest MSA options:
- Cover vs the prefilter disc: the disc is the filter media (consumable); the cover is the reusable holder — you need both.
- Cover + disc vs Advantage P100 filter: the P100 filter is a higher-efficiency replaceable unit; cover + N95 disc is the cheaper, lower-class route.
- Cover route vs GMA/P100: the combo cartridge needs no cover or disc, but costs more per cartridge.

How this is approved, and what the approval covers
Respiratory protection in the US is approved by NIOSH under 42 CFR Part 84, and used under OSHA 1910.134, which requires a written program, medical evaluation, training and fit testing wherever a respirator is required.
The point that matters for a component or accessory: a NIOSH approval attaches to an assembled configuration, not to a part in isolation. A cover, guard or filter carries the approval only in the combinations listed on the manufacturer's approval label. Mixing parts across brands, or across series within a brand, voids the approval even where the parts physically fit — which they often do. Check the approval label for the exact assembly before ordering.

Worked great on MSA mask
Worked great on MSA mask. These are a combo chemical and P100, which came with the MSA mask combo originally purchased. The chemical protection was not needed in our case for demo and sanding, but it is not any more expensive, and is nice to have for other projects instead of switching back and forth between cartidges

Great product by MSA
Home Depot decided not to carry MSA anymore, so I had to get these filters here. There isn't much to say here except that these fit my MSA respirator and I am glad they do because my MSA respirator is better than my 3m respirator and I will argue that it's better all day long. These filters also aren't ridiculously overpriced like 3M filters. I'm not a 3m hater by any means I like their other safety products like their ear plugs. When it comes to respirators and filters MSA is the best in my opinion.

A great product for anyone working in dusty conditions.
These filters are primarily for high dust conditions and are used in conjunction with the MSA 815444 mask. They are replaceable and depending on the frequency and conditions of their use, should be replaced at reasonable intervals.

So relieved to find replacement cartridges for my old respirator mask.
These fit perfectly on my old MSA respirator. I've used disposable 3M P95 respirator masks for a few days, but they didn't filter as well as these. Particulate matters like drywall dust and smoky air from frie were all prevented from entering my respiratory system.Be sure to store your respirator and cartridges in a zipped plastic bag to prevent air from going through the filters; otherwise, you're letting the filters filter unnecessarily because leaving your mask out means letting air flows through the filters, i.e. the mask is working when not in use.

Works well for wood dust, better breathing
I use this while working with wood dust with the MSA Advantage 200 LS Half-Mask.These filter are much easier to breath through than with the one that came with my 817662 model (Paint and Pesticide).Of course these filters are for dust only, they do not work for chemicals, odors and paint.

Just what I've been looking for.
They're filter cartridges, what more can I say. Was delighted to see that Amazon still carried this style of filter by MSA, as they have been difficult to find in most local stores within the last few years. Fit an older style of respirator without issues. So far satisfied with product.(Shipping was fast, and the package along with the contents within were in ideal condition. My only complaint was that I had ordered 10 filter cartridges, and only received 9 within the package).

Perfect replacement for my MSA respirator
I purchased my MSA respirators from the hardware store some years ago. Before starting to add more insulation in my attic, I decided it was time to replace the filters. I was actually surprised at how few options and/or expensive it was to do so back at my local hardware store! These were exactly what I needed and were very easy to replace.
