Ask KHN-PolitiFact: Is My Material Masks Good Sufficient? The 2022 Version

By Victoria Knight, Kaiser Well being Information

The extremely transmissible omicron variant is sweeping the U.S., inflicting an enormous spike in covid-19 circumstances and overwhelming many hospital techniques. In addition to urging Individuals to get vaccinated and boosted, public well being officers are recommending that individuals improve from their material masks to higher-quality medical-grade masks.

However what does this even imply?

At a current Senate Well being, Training, Labor and Pensions Committee listening to, high public well being officers displayed several types of masking. Dr. Rochelle Walensky, director of the Facilities for Illness Management and Prevention, wore what gave the impression to be a surgical masks layered underneath a material masks, whereas Dr. Anthony Fauci, chief medical adviser to the president, wore what appeared like a KN95 respirator.

Some native governments and different organizations are providing their very own insurance policies. Los Angeles County, as an illustration, will require as of Jan. 17 that employers present N95 or KN95 masks to staff. In late December, the Mayo Clinic started requiring all guests and sufferers to put on surgical masks as an alternative of fabric variations. The College of Arizona has banned material masks and requested everybody on campus to put on higher-quality masks.

Questions concerning the stage of safety in opposition to covid that masks present — whether or not material, surgical or higher-end medical grade — have been a topic of debate and dialogue because the earliest days of the pandemic. We appeared into the query final summer time. And as science modifications and variants emerge with larger transmissibility, so do opinions.

The Facilities for Illness Management and Prevention has not up to date its masks steering since October, earlier than the omicron variant emerged. That steering doesn’t suggest using an N95 respirator however states solely that masks must be a minimum of two layers, well-fitting and comprise a nostril wire.

A number of consultants we consulted stated that the present CDC steering doesn’t go far sufficient. In addition they agreed on one other level: Sporting a material masks is healthier than not sporting a masks in any respect, however should you can improve — or layer material with surgical — now could be the time.

Though material masks might look like extra substantial than the paper surgical masks possibility, surgical masks in addition to KN95 and N95 masks are infused with an electrostatic cost that helps filter out particles.

“From the angle of understanding how covid is transmitted, and what we learn about omicron, sporting a higher-quality masks is actually essential to stopping the unfold of omicron,” stated Dr. Megan Ranney, educational dean for the College of Public Well being at Brown College.

A large-scale real-world examine carried out in Bangladesh and printed in December confirmed that surgical masks are simpler at stopping covid transmission than material masks.

So, one simple technique to enhance safety is to layer a surgical masks beneath material. Surgical masks could be purchased comparatively cheaply on-line and reused for a couple of week.

Ranney stated she advises individuals who go for layering to place the better-quality masks, such because the surgical masks, closest to your face, and put the lesser-quality masks on the surface.

Should you’re actually pressed for assets, Dr. Stephen Luby, a professor specializing in infectious ailments at Stanford College and one of many authors of the Bangladesh masks examine, stated surgical masks could be washed and reused, if funds are a difficulty. Almost two years into the pandemic, such masks are low cost and plentiful within the U.S. and plenty of retailers make them obtainable freed from cost to prospects as they enter companies.

“In the course of the examine, we informed the contributors they might wash the surgical masks with laundry detergent and water and reuse them,” Luby stated. “You lose some impact of the electrostatic cost, however they nonetheless outperformed material masks.”

Nonetheless, consultants keep that sporting both a KN95 or an N95 respirator is the very best safety in opposition to omicron, since these masks are extremely efficient at filtering out viral particles. The “95” within the names refers back to the masks’ 95% filtration efficacy in opposition to certain-sized particles. N95 masks are regulated by the Nationwide Institute for Occupational Security and Well being, whereas KN95s are regulated by the Chinese language authorities and KF94s by the South Korean authorities.

Individuals had been initially urged to not purchase both surgical or N95 masks early within the pandemic to make sure there can be a ample provide for well being care employees. However now there are sufficient to go round.

So, in case you have the assets to improve to an N95, a KN95 or a KF94 masks, you must completely achieve this, stated Dr. Leana Wen, a professor of well being coverage and administration at George Washington College. Though these fashions are costlier and could be extra uncomfortable, they’re definitely worth the funding for the protection they supply, she stated.

“[Omicron is] a way more contagious virus, so there’s a a lot decrease margin of error regarding the actions you had been as soon as capable of do with out getting contaminated,” Wen stated. “Now we have to extend our safety in each manner, as a result of all the things is riskier now.”

Wen additionally stated that although these masks are characterised as one-use, except you might be in a well being care setting, KN95s and N95s could be worn greater than as soon as. She makes use of one in every of her private KN95s for greater than per week at a time.

One other vital factor to notice is there are various counterfeit N95 and KN95 masks being bought on-line, so shoppers should be cautious when ordering them and make sure to get them solely from a professional, trusted vendor.

The CDC maintains a listing of NIOSH-approved N95 respirators. Wirecutter and The Strategist have each printed guides to buying authorised KN95 and KF94 masks. Ranney additionally recommends consulting the web site Undertaking N95 or engineer Aaron Collins’ “Masks Nerd” YouTube channel.

And keep in mind, the chance of transmission relies upon not simply on the masks you put on but additionally the masking practices of others within the room — so going into a gathering or restaurant the place others are unmasked or sporting solely material masks will increase the percentages of getting contaminated, regardless of how cautious you might be. This chart demonstrates the massive variations.

Even with a masks improve, if you’re nonetheless nervous about omicron and, specifically, a critical case of covid, the No. 1 factor you are able to do to guard your self is get vaccinated and boosted, stated Dr. Neal Chaisson, an assistant professor of medication on the Cleveland Clinic.

“There’s been quite a lot of discuss individuals who have been vaccinated getting omicron,” stated Chaisson. “However I’ve been working within the ICU and doubtless 95% of the sufferers that we’re taking good care of proper now didn’t take the recommendation to get vaccinated.”
