Guide to Face Mask Selection and Use

What is the ASTM level of our respirator?

This is a question we get a lot.  The answer isn't that simple.  With the Aspen Air respirator frame, you can use whatever filter media you have available.  So if you have NIOSH tested N95 filters, you would have the highest level of filtration and protection available.  Today we are selling 4-ply surgical grade material which is ASTM level 3 according to this chart.

We plan to have early May a melt-blown material that is electrostatically charged to have the same properties of N95 mask, just no certifications because we are using the raw material and not putting it into a face mask because we have a respirator frame that holds and seals the material.
