I feel like they just had an odd look to them, they are a KF94 design recertified as N95. But if you find them comfy when they make a good seal, that's what counts. Some of the comfort may also be the breathability, Auras have a pretty low pressure diff between the inside and outside when in use. If you want that low pressure difference in a traditional N95 style, Indiana Face Mask makes some top notch high-filtration high-breathability N95s that are similar. Both they and the Auras usually test above 99.5% filtration, the Auras usually have a little bit of a petroleum smell but if it's bad enough that it makes the mask deeply unpleasant to wear, you probably have a fake (sometimes factory rejects get resold etc.).
