This package of Ranto disposable face masks contains 50 masks. The masks have a nose clip and passed a number of tests I do on each paper mask to ensure they are reliable (more on the tests below). I did not find the ear loops too tight, and none has broken so far. Note that I am a small size female, and I rarely find ear loops too tight on the masks labeled 'for adult.'
The masks fit comfortably over my face, do not pull on ears too much, and breathing in them is very easy. I took the mask on and off several times while testing it, and the loops stayed attached and did not snap off, which appears to be a common issue with some of these masks.
I found five tests to tell apart fake masks and real masks. I performed three of the tests. The main test is the "water" test, which shows that the mask does not let through the water. This means it keeps my spittle inside the mask and keeps other's people spittle away from me.
Since the masks passed the three tests, I did not do the burn test, so I would have to destroy the mask.
Below are the five tests to tell part good face masks from bad ones:
1. Light penetration
The real mask does not let the light through; the fake mask lets the light through.
2. Blow out a flame
You cannot blow out a flame through a real mask; you can flow out a flame through a fake face mask.
3. Hold water
The real mask holds water, the fake mask leaks.
4. Burn test
The filter in the real mask melts but does not burn; the filter in the fake mask burns with a flame.
5. Electrostatic attraction test
The real mask attracts particles; a fake mask does not.
