Why did this mask fail?
Country of Origin
I purchased two boxes of Puravita KN95 since US and local manufacturer. Fit was good as well as breathability. The major problem why I stopped using them is ear loops separated from mask on about half of masks after two or three wearings. I sent an email to Puravita informing them of problem and they never responded, back to my KF94 mask.
