### ⭐⭐⭐⭐⭐ Best Value Medical Grade 3 Mask?
*by H***P on July 19, 2022*

I purchased the DEMETECH ASTM 3 Surgical Mask based on Armbrust's YouTube channel review. It seems like a great mask for the price (less than 50 cents each). This high quality USA made mask, has an extremely high filtration level (over 99.168%) and high breathability level (53.8 pascals), according to Armbrust's tests. This makes it a no-brainer. However, there are some cons. The ear loops are too loose, so the mask does not seal properly to my face. The easiest solution is making a "Slip Knot" on each ear loop. To learn how to make one, search for "Adjustable Ear Loops" on the "Hacks by Dad" YouTube Channel. Second, the elastic is installed on the inside of the mask. In another YouTube video, Lloyd Armbrust explained that it's better to have the elastic welded on the outside of the mask, because it seals better. Also, it would be nice if the masks were individually wrapped.
