Without a nose clip on a mask design like this, there's almost no possible way it could offer N95 level protection. The one you've linked to appears to be without. This particular manufacturer appears to offer models with and without a nose clip, which is essential to have and use. We will require independent testing with equipment to verify this, but there have been scandals in the news lately, here in Taiwan, around mask manufacturers making unsubstantiated claims. It may be just the manufacturer's claim, and not that of a proper certifying body (like the NIOSH in the US, responsible for N95 certification) that the mask's MATERIAL and not the mask itself, filters and protects from PM2.5. For now, there are some concerns quite worth mentioning about it. Hi, yes, we have a sample of that very mask here and will be doing a review of it in the future, so do watch for it.
All in all, an excellent mask that provides comfortable protection from fine particle pollution (PM2.5) and additional value through some of its more durable construction features. This is a significant improvement over the original 9211's rubber straps, and is signified by the "+" designation to the model. A month of daily use can generally be expected. These extend the usable life of the mask over those with thin rubber straps which typically tend to break after a few days. Lastly, the 3M Aura 9211+ also scores higher marks for its durable braided elastic headbands. Therefore, it's all the more necessary with a proper seal to include an air exhale valve. For an N95 is to work properly, face fit and an air tight seal are imperative, yet once this is achieved, comfort tends to drops dramatically with the resultant buildup of heat, moisture, and trapped CO2. Conversely, the lack of any degree of a proper seal such as in common surgical masks, with their large air gaps along the sides and nose, are precisely why they're perceived as comfortable as well as a major reason why they're ineffective. The valve greatly enhances the potential for wearer compliance by avoiding heat and moisture buildup and allowing exhaled CO2 to escape from the mask. Additionally, the 9211+ significantly bests many other masks by the inclusion of an exhale valve, an essential feature for N95s used for any lengthier period of time. Since a less-than-ideal face seal will always preclude the effectiveness of any mask, the Aura line's design appears to stand head and shoulders above the rest. In contrast to older cup-style N95s, the 3M Aura line features a more sophisticated three-panel design which can provide an excellent fit and face seal. The fit achievable with the Aura line is industry leading. Richard Saint Cyr, presented fit testing data carried out in China on a number of masks, and it was the 3M Aura line which rated very significantly above all other N95 masks.

The 3M Aura series 9211+ is something of a standout among all other masks reviewed to date.
