The 3M Corporation is a multinational American organization that works in the fields of industry, employee protection, health care, and consumer products in the United States.
The company produces over 59,000 products under many names, including passive fire prevention, personal protective equipment, window films, paint security films, healthcare applications, and optical films. It is situated in Maplewood, a suburb of Saint Paul in Minnesota.
3M created $32.8 billion in net sales and ranked 95th in the Fortune 500 list of the largest U.S. companies by gross revenue. The company had around 93,500 staff as of 2018 and had operations in more than 70 nations.
3m n95 masks effectiveness
3M is a world-famous N95 mask brand. It has NIOSH certification and comes in different forms and sizes. Below, A Rain will introduce the differences between 3M mask designs.
N95 masks are particulate safety masks that are capable of removing non-greasy solid or liquid particles of 0.3 microns or greater in diameter. However, any time you wear an N95 mask, you must test the edge seal of the mask (Fit Test) to ensure there is no real leakage protective effect. For individuals with hair on their faces and children, N95 masks are therefore not suitable, because these individuals cannot guarantee the tightness of wearing N95 masks.
An optional exhalation valve comes with some disposable N95 masks. "The inclusion of an exhalation valve reduces resistance to exhalation, making it easier to breathe (exhale)” according to the CDC.
Non-woven polypropylene material
Polypropylene is versatile since it can carry a static charge that repels particles. While an N95 mask is created to retain the charge for the life of the mask, you can produce a charge with a homemade filter by ironing the polypropylene or 20 seconds of rubbing it with a rubber glove. The Chu notes that the charge will last for around 12 hours or until it has been cleaned.
How many n95 masks have 3M manufactured?
3M Co. said that by June, the latest ramp-up in the manufacture of one of the most critical pieces of coronavirus-fighting protective gear would increase U.S. production of its N95 respirator masks to 50 million per month.
One of the world's largest manufacturers of N95 filter masks, 3M based in Maplewood, Minn, has steadily expanded its production capacity in recent months as demand for n95 face masks has exploded. Health services around the world, mostly in countries facing their own coronavirus outbreaks, are facing shortages of n95 masks that are mostly manufactured abroad.
Only a week before, 3M said that the mask was "trying to operate at high productivity" resulting in more than 100 million of them every month, 35 million of them in the United States. But in the next 12 months, it vowed to carry more online manufacturing and double demand again to 2,2 billion marks (including n95 masks) a year.
In the United States, at least some of the demand growth is coming. Producing 50 million masks (including n95 respirator) a month is an improvement of 40 percent relative to current levels.
CEO Mike Roman said in a statement that 80% of the U.S, the supply of N95 goes to health care customers,(the N95 masks are also used in food processing, pharmaceuticals, and energy sectors) and 80% of the masks intended for health care are sent to existing distributors of 3M; the remainder is sent for sale to the federal government.
He said “to speed up distribution even further, We collaborate together with these affiliates, which in some cases includes moving pallets directly from our factories into vulnerable places.”
The criticism comes after 3M attracted attention from billionaire Mark Cuban, who blamed the firm for high prices for some distributors charging N95 masks. 3M said it opposed cost-gouging and urged the U.S. William Barr's Attorney General to crack down on profiteers. Roman said, “3M will not tolerate any such operation”.
Although with the new development, Roman said the fact is that N95 respirator demand is much higher than the capacity of the industry to produce. So, 3M partners with unidentified sterilization firms to find a way to disinfect and reuse existing n95 masks securely, something that many hospitals attempt to stretch their existing stocks on an ad-hoc basis.
Trump administration dealer with 3M about n95 masks
Over the next year, the Trump administration has negotiated an agreement with US manufacturer 3M to import over 166 million n95 respirators from China and allow 3M to continue exporting its US-made n95 respirators.
The negotiation splits a deadlock that originated in Washington stopping the export to Ontario of almost three million specialized n95 masks, raising concerns that by the end of the week the most populous province of Canada will run out of supplies for medical workers fighting coronavirus.
As Roman said in a written statement, “I want to thank President Trump and the government for their management and cooperation. The 35 million N95 respirators we currently manufacture in the United States each month will be replaced by these imports.”
Under the program, over the next three months, 3M will import 166.5m respirators (masks that form a seal over the mouth and nose and provide much higher protection than surgical masks) from its factories in China.
