Wanting some recommendations on N95 masks that you have found breathable/comfortable, especially if you have a condition like COPD?
I have been looking at nano type masks from AMD and Soomlab. Has anybody bought from both, and can comment on their breathability and quality?
N95 masks by default are not comfortable due their intended purpose of minimising molecule size exchange through the filter mesh.
If you have difficulty breathing, you'll want something like the Uniqlo Airism masks but of course they're just cloth and don't provide N95 levels of protection.
Maybe best compromise if you do want better protection is the protruding half-masks like the image below which gives you some air space between nostrils and the mask rather than being straight up close to it.

Most places suggest N95 and FFP2 are very similar. 3M's own spec sheet below, page 2, shows FFP2 to be >94% filter performance vs N95's >95% but a whole extra 10 litres of air per min difference which will obviously help you breathe better, as well as the much reduced inhalation/exhalation resistance too.

Basically, I think you should consider FFP2 masks instead of N95 for easier breathing.
