The ElastoMaskPro is the most breathable N95 I've tested that also filters well above the minimum N95 standard.

The ElastoMaskPro is an innovative mask that is made entirely out of a single piece of silicone, even the straps. It's meant to be as simple to use as an N95 filtering facepiece respirator, but have the great seal and lasting reusability of an elastomeric respirator. Unlike a lot of source control respirators on the market it is not a slightly altered existing industrial mask. ElastoMask Pro was designed from the ground up to be for healthcare workers.

I think there are some advantages and disadvantages to the design, but overall I'm impressed. It offers incredible breathabilty, around twice as breathable as my 3M Aura N95s, but also has outstanding fit and filtration. When I first wore it for a few hours to try it out, it was so breathable I never felt a need to immediately take it off when in a safe environment.

I was given the masks for free to review, and if it seems like I'm gushing a bit in the video it's because of the breathability and the test results not because I got them free. In Part 2 I'll show the comparison testing I did against a Dentec NxMD with N95 filters and a 3M Aura and you'll see why. In that video I'll also have full comparisons of speech intelligibility of different respirators, measurements of the strap tension and more.

Overall, I don't hesitate to recommend ElastoMaskPro in terms of performance as an incredibly breathable N95 elastomeric that fits and filters very well and is easy to use.

Whether it might be right for you is a more complicated question that involves individual fit and overall value. As of the time of this review, it is an $80 mask, which is comparable to other high quality respirators I sometimes call "boutique" respirators, such as FloMask and Envo Mask, to distinguish them from their less expensive industrial counterparts. Check the Part 2 video when that comes out for more details. But if it's in your price range I definitely think ElastoMaskPro is a mask worth considering.

Addendum 11/23/22:
I'm editing part 2 now, including the video when I took the mask off after wearing it for 3 hours. It left quite an impression on me, literally. The pressure marks on my face are more prominent than in the post fit test video in part 1. The ElastoMaskPro seals really well on me, but the pressure marks on my nose bridge and from the straps on my cheeks are an indication the mask may not be the best fit for me in terms of the distribution of pressure on my face.

Update 12/1/22
Just got off a webex call with some of the people behind ElastoMaskPro and found out the mask has a 1 year warranty. I think that is something that may help with concerns about the durability of the straps. I'm not even sure if any of my other elastomerics have warranties. I'm not sure yet what exactly the warranty will mean in practical terms, but I was kind of surprised it exists.

And as to whether talking with them influenced me, definitely. They are all really nice and it was interesting to hear about some of the engineering that went into the mask, including fluid dynamics calculations that went into the air flow, which is why the small slits under the filter covers work so surprisingly well. And that one of the challenges in designing the seemingly simple mask with fixed straps was finding data on head circumferences since that isn't part of the NIOSH guidelines for mask fit test panels (panels which aren't part of for approval of particulate respirators, but apparently can be for vapor filtering masks).

Note 12/12/22:
As with any video where I have received a test sample for free, I've tagged this video as "Includes Paid Promotion" since that is YouTube's term for whether you receive any compensation for a review, and under FTC guidelines a test sample is considered compensation. That is the full extent of this being a "sponsored" video. No review approval or other compensation than masks to test. I did receive one request, which is if I could include an example of speech while wearing the mask, but the test samples were not contingent on that. I created a separate speech comparison video because it's an issue I was going to test anyway and though would be useful to people.

---
In the video I'm using a PortaCount mask fit testing machine that gives scores in "Fit Factor". Fit factor is the the concentration of ambient particles outside the mask divided by the concentration inside the mask. So if there were 1000 particles outside and 10 inside, 1000 divided by 10 is 100, so the air inside the mask is 100 times cleaner and the fit factor is 100. The Portacount counts particles from .02 to 1 micron in size.
