Interesting FFM

[Akimbo]

This FFM looks like it could be adapted for quite a few dive applications: ViriMASK

Has anybody seen one?

BS
It is not good mask for viral protection. Any FFP3 respirators with valves even better. reasons: this mask has not valves! so, it has huge dead space for CO2. also filter will filled fast with vapor from breathing, and decrease usage time. It has not airflow separation inside the glasses, and has not ventilation of glasses...
Also dump shape of filter... it is good for vacuum cleaner, but for mask... it has less used areas, and most used... also decreased usage time...
Also placing for filter... closed viewing space... high weight in front, that require so strong belts...
Also - whole changable box of filter.... Just make the cartridge box equal and fits to one of vacuum cleaner HEPA filters shape - and you can get great advance

I thing inventors of this mask had influence of one very famous mask

see - same triangle shape of "chews"

... but idea is very good... just need some minor changes.

... for diving - no. No valves, cylindrical single glass. no...
p.s. gas masks is much better for rework

I was thinking that an adapter could be fabricated or 3D printed to replace the filer with inhalation/exhalation mushroom valves, mic, and/or 2nd stage regulator.

Yes, but anyway inner design is too difficult to rework (glass blowing), in compare with gasmasks with near-the-same price...

Probably, but you can get that sort of FFM purpose built for scuba for the same money. [Hot Item] Diving Mask Scuba Diving Full Face Mask Full Face Black Rubber Dive Mask

Mount a regulator and Robert is your father's brother.

That old Cressi FFM in your link, which goes back to the 1960s, doesn't have an oral nasal mask like this one, nor is it well-suited to mounting a mic. I only pointed this one out because it could be a useful platform for concept development.

The virimask is an oronasal mask with an attached, but separate safety goggle section. Obviously an issue if you were to turn it into a diving mask. Even if you add vents between the sections, adding an equalizing block looks tricky.

I would think that you could squeeze the mask to pinch your nose. We used oral-nasal masks all the time in chambers on BIBS and no trouble equalizing.

I think the clear portions are hard plastic, basically the goggle frame and the triangular part of the mask. It's only the milky-colored parts that are silicone.

It looks like a silicon nose pocket to me. I could see needing a small pressure equalizing hole for the eye-pocket and clearing.
