Centre Warns Against 'Inappropriate Use' of N-95 Masks With Valved Respirator
Jul 24 2020
They say these masks, which are as effective as N-95 masks, were created to be easily sterilised and used many times.
"The use of valved respirator N-95 masks is detrimental to the measures adopted for preventing the spread of coronavirus", said the Union Health Ministry, warning against the used of such masks.
Actually, the CDC said N95 respirator masks in general (with or without a breathing valve) should only be worn by healthcare professionals who are required to undergo training to ensure correct use and fit.
In the study, the developers estimate the rough cost of the masks could be as low as about US$7 each, with filters perhaps 50 cents each; after a little more than a dozen uses, iMASC could thus become a more economical option than N95 masks costing a dollar each. Any cotton clothes can a used as a cover for face and mouth.
Dr Garg stated, "It has been observed that there is inappropriate use of the N-95 mask (particularly with valved respirator) by the public other than designated health workers". In recent weeks, the World Health Organization acknowledged that the virus can spread via aerosols in the air, but stopped short for strongly recommending face masks. "When you exhale, the expired air goes out of the valve in the N-95 mask".
Of all the face masks that you can find in stores right now, the ones that are marked N95 are supposed to be among the safest, offering better filtration that the regular surgical masks.
But if you have been relying on the N95 masks to protect yourself and the people around you, you have it all wrong! "If a COVID-19 patient is exhaling through the valve in the mask and there is another person in front wearing only a cloth mask, it does not really eliminate the risk of being infected. In this regard, I would like to draw your attention to the advisory on the use of home-made protective cover for face and mouth available on the website of the MoHFW". The advisory also stressed on their regular washing and cleaning in boiling water and stated that any used cotton cloth can be used for the goal.
The colour of the fabric does not matter but one must ensure that the fabric is washed well in boiling water for five minutes and dried well before making the face cover, the ministry advised.
Adding salt to this water is recommended, it said. From the looks of it, the government insisted on people using a homemade solution, explaining that the covers will need to be washed and cleaned each day. "Every member in a family should have separate face cover", the advisory stated.
