Due in part to the shortages of N95 respirator masks, you may have seen a surge in popularity of the KN95 face mask that has recently been made available on the market.The name is very similar to the N95 respirator mask that is approved by the FDA for medical use, so you may be wondering what the differences are between these two. You may also have also heard some negative press surrounding certain manufacturers of these masks.http://www.polydisposable.com/
