A dust respirator mask is different from the ordinary masks that are used to protect our breathing intake from a harmful environment. Dust respiratory masks N95 are usually worn by people who have dust allergies or work in the dusty environment all-day like sweepers, dusting, gardening, etc. These masks help the toxic dust particles to enter in the mouth.
You can buy n95 corona mask online easily if not available in the market. But one thing to keep in mind while buying a corona mask N95 is that NIOSH label is printed either on the mask or on the box. Many people buy any dust mask, which gives them no protection.
What does N95 stand for? It means none resistant to liquids and oils, but it has 95% efficiency to filter out the dust particles entering. As coronavirus is becoming the new sensation in the world, it is our duty to take precautions beforehand.
