Why does the CDC recommend N95 masks?

According to updated guidelines from the Centers for Disease Control and Protection, N95 masks “provide the highest level of protection” against the spread of COVID-19. Many experts have criticized the CDC for discouraging Americans from using N95 masks early in the pandemic and not recommending them sooner.

While CDC Director Dr. Rochelle Walensky said “Any mask is better than no mask”, N95 respirators can filter at least 95% of aerosol particles as small as 0.3 microns. The elastic headband and adjustable metal band across the bridge of the nose on an N95 mask also help create a much tighter seal than cloth masks.

Inspected and approved by the National Institute for Occupational Safety and Health, N95s are also made from polypropylene, a plastic with a built-in electrical charge that attracts foreign particles – like virus droplets – and traps them inside. inside the fibers of the mask.

According to an August 2020 report in the Journal of the American Medical Association, N95s are the “pillar of protection against airborne pathogens.”

How long can an N95 mask be worn?

According to the CDC, you shouldn’t use an N95 mask more than five times in total. Any deterioration or fraying of the straps means they are not creating a tight seal and should be discarded.

Medical experts generally agree that the COVID-19 virus does not survive on surfaces for longer than three days. Going through your N95 masks every three or four days should ensure they are virus-free.

The duration of wearing the mask is more important than the frequency. Richard Flagan, a chemical engineer at the California Institute of Technology who studies masks and aerosols, told The Associated Press that N95 masks should be limited to two or three days. The CDC recommends health workers use N95 masks no more than five times.

Experts have tested methods for cleaning and reusing N95 masks, including exposing them to vaporous hydrogen peroxide or ultraviolet light, but neither method has been approved by the Food and Drug Administration.

A 2020 study in the Journal of Emergency Medicine looked at boiling face masks and letting them air dry, but the results weren’t peer-reviewed and haven’t been endorsed by regulators.

CVS, Walgreens, Kroger, Rite Aid, Publix, Walmart and Sam’s Club are among many US retailers that are part of the Federal Retail Pharmacy Program and will be giving away free N95 masks. Customers will be limited to three masks per person, officials said, to “ensure broad access for all Americans.”

Many CVS and Rite-Aid locations have started offering free masks, and Walgreens has a running list of locations nationwide that offer free masks, with “signage indicating mask availability” outside the store. store.

Walmart said the free N95 masks should be available “the second week of February” and that “eventually all Walmart and Sam’s Club locations will have N95 masks.”

When should you use an N95 mask?

Due to supply chain issues, the CDC had previously recommended that N95 masks be reserved for healthcare workers. With more than 750 million masks in the strategic national stockpile, the agency now says there are enough for anyone to wear.

The agency clarified that “surgical N95s,” a specific type of respirator with additional safeguards, should still be reserved for healthcare workers.

When should you wear an N95 mask? The CDC recommends using one:

  • In public transports
  • In crowded indoor spaces or outdoor spaces where you cannot socially distance
  • For people who have to interact with large groups of people
  • For people who are not vaccinated or not up to date with boosters
  • For people at increased risk of developing a severe response to COVID-19
  • For those caring for someone who has tested positive for COVID-19

Most N95 masks are designed for adult faces and lungs, with only a handful of manufacturers making KN95s and other high-quality masks suitable for young children.

How much do N95 masks cost?

Demand — and price — for N95 masks jumped after the CDC revised its guidance, according to Bloomberg. A pack of 50 Kimberly-Clark N95 masks cost around $24 in early October, but now sells on Amazon for around $57.

N95 masks typically come in packs of 10, 20, or 50. On Project N95, a nonprofit organization that verifies personal protective equipment, the cost of a box of masks was around 2 to 2, $50 per mask.

How to avoid counterfeit masks?

As demand for high-quality masks grew, so did counterfeits: according to the CDC, 60% of KN95 masks failed to meet required standards.

To make sure your N95 respirator is not counterfeit, look for the NIOSH approval symbol, which should start with the letters “TC” followed by seven numbers.

Ignore anything labeled “FDA Registered”: According to the Food and Drug Administration’s website, facilities involved in the production of medical devices are required to register each year, but that doesn’t mean they have to. have been approved or authorized.

Carefully review seller ratings and product reviews and be wary of new sellers who seem to pop up out of nowhere.

Since KN95 respirators are not regulated by NIOSH, it is harder to spot a fake. But the FDA still keeps a list of approved KN95 masks from 2020, when it approved them for use under an emergency use authorization.

The CDC also has a list of N95, KN95, KF94, and other non-NIOSH-approved face masks that have passed filtration testing, as well as known counterfeits.

However, the best way to ensure that you receive a NIOSH-approved mask is to get one directly from a healthcare professional or a reputable retailer like CVS or Walgreens.

You can also rely on trusted online resellers like Project N95.
