| Flo Mask | Yes | Has a nose bridge option which is nice, but the mask is smaller than I'd like | The mask is light, which is good, but getting a good fit for me requires too much tension on the lower adjuster which puts pressure on my jaw. | Mediocre | For sitting, fine. For walking, barely acceptable. Airflow on the Flo Mask is significantly worse than most disposable N95s and proper industrial cartridge filters due to having a tiny surface area. | Supposedly the pro filters are basically as good as an N95, but there's very little material and it's _very_ thin. For whatever that's worth. Anecdotally and not medically relevant per se, but more irritants make it through the flo mask than many other masks. |
| MSA 9000 | Yes | Large size fits my face well. However, other than the hatband style sizing on the top piece, there's only one point of adjustment. | Pretty light weight and relatively comfortable. I don't love the feeling of the mask material but it's okay. Because of the way the adjustment works, the weight can be concentrated on my nose. | Bad | Already kind of marginal for sitting. Only takes low-profile cartridges which have relatively small surface area. | P100 cartridges. |
| 3M SecureClick | No (Possible to mod) | Large size is great | With full-size cartridges, it's heavy, but otherwise it's the most comfortable I've tried | Fine (because it lacks source control) | With full-size cartridges, airflow is _great_. | Lots of industrial cartridges available. |
| GVS Ellipse Source Control | Yes | Not great, weird shape. (Too narrow?) | Not great | Bad | Not great. The cartridges have a fair amount of surface area compared to MSA's low-pro ones, but still don't move much air. | Limited options. |

| 3M V-Flex | The issue here is that the straps join in the middle of the mask, so it depends to become loose at the bottom. Requires frequent adjustment to keep in place. | Great | Great | N95 |
| Indiana N95s | These seem to fit me pretty well but the mask itself does not inspire as much confidence as a 3M. The elastic strips on these often feel like they're in danger of breaking as well. | Good | Good | N95 |
