At the same time as masks mandates start to raise throughout the nation, many individuals nonetheless want high-quality masks for air journey, purchasing and visiting the physician. Top-of-the-line choices is the KF94 from South Korea.
KF94 stands for “Korean filter” and “94 p.c” filtration. The KF94 was developed in South Korea for public use, and in contrast to the N95, which is the respirator-style masks permitted in america, the KF94 is offered in grownup and little one sizes. In Korea, the masks vary in value from 529 gained to 1,244 gained (about 50 cents to $1); most on-line sellers in america cost about $1 per masks. Like different respirator-style masks, a KF94 may be worn for a complete of about 40 hours, in any mixture of brief or lengthy increments, so long as it stays clear and continues to suit snugly on the face.
A extra breathable masks
Many customers say the KF94 is extra snug and simpler to talk and breathe in than different respirator-style masks, as a result of the design creates more room between the masks and the mouth. The masks, which has ear loops, arrives flat in a single package deal and unfolds to disclose further flaps, together with one with a moldable nostril bridge, that give full protection from the highest of the nostril to below the chin, with no gaps.
Yoon S. Byun, a photographer and filmmaker in Portland, Maine, just lately bought KF94s for his kids, who’re 4 and 6, after studying about them in The New York Occasions. (Mr. Byun has freelanced for The Occasions.)
“Our youngsters are fairly good about retaining masks on, but it surely took a day or so for them to get used to the 2 flaps, and each morning we pinch the nostril half earlier than they go to highschool in order that they conform to their faces,” Mr. Byun stated. “Beforehand, our youthful son would undergo at the least two material masks a day as a result of they might get soaked, however he’s in a position to put on these all day as a result of they don’t press up in opposition to his mouth. Each appear to love them and say they’re simple to breathe in.”
Stricter regulatory controls
Dr. Ashish Jha, dean of the Brown College Faculty of Public Well being, stated one of many advantages of the KF94 is that Korea imposes strict controls on masks manufacturing and approval.
For a masks to be licensed by the Ministry of Meals and Drug Security in South Korea, masks makers should submit an utility that features particulars about product growth, lab take a look at information and proof of product security and efficacy. The ministry inspects a number of thousand masks a month to ensure they meet authorities requirements, in accordance with a written assertion from an MFDS consultant.
Though some counterfeit KF94s have emerged in latest months, total there appear to be fewer counterfeits within the provide chain in contrast with N95s or KN95s, the respirator-style masks permitted in China. “It’s a a lot, a lot tighter regulatory regime,” Dr. Jha stated.
The penalties for promoting an unapproved masks or one that doesn’t meet requirements are steep, together with fines, suspension of product gross sales and as much as 5 years in jail. In latest months, the ministry has been concerned in a number of excessive profile crackdowns on unlawful masks manufacturing and distribution. In April 2021, the company prosecuted 4 folks for promoting 11.4 million fake masks. And in December, the ministry uncovered 16 firms in Busan, South Korea’s second largest metropolis, that had been manufacturing and promoting pretend masks.
spot a counterfeit KF94
Regardless of the company’s efforts, some counterfeit masks have nonetheless discovered their method to on-line shops, together with on Amazon, so it’s necessary to search for a couple of key options to be sure you’re getting an actual KF94.
Whereas the MFDS has a portal to verify whether or not a masks has been permitted, it’s helpful provided that you’ll be able to learn Korean. Once we used the English model of the location, the search perform didn’t work. Just lately, we used the Korean database to lookup 17 completely different KF94 masks manufacturers being bought on Amazon. Eleven of the manufacturers had been respectable, 5 had been counterfeits and the standing of 1 was unclear.
The respectable masks we discovered on Amazon embrace these made by KN Flax, LifeSys AST Preserve, Pleased Life/Good Day, Instalashes, Yolo Studio, AnyGuard, Pleased Day, Pleased Life Children, FlexMon, Petseeker and Puremate. However on condition that counterfeiters can copy model names, you continue to have to do some homework and verify for different indicators that the masks meets KF94 requirements before you purchase it.
Aaron Collins, an engineer who routinely exams masks and has gained a following on YouTube because the “masks nerd,” recommends shopping for KF94s from Korean magnificence product importers like Be Healthy or KMact. Mr. Collins has additionally created a spreadsheet displaying the entire KF94 and different masks manufacturers he has examined. Look within the “filtration effectivity” column to see how the masks carried out.
The MFDS gives further steering for locating an authorized KF94. Right here’s what to search for.
Made in Korea. The masks ought to state clearly on its web site and packaging that the product is made in Korea. Any masks that claims to be “KF94-style” or is made in China or one other nation just isn’t an actual KF94. Don’t purchase it.
Flat, shiny, single-use package deal. KF94s are available in single-use flat envelope-style packages with a notch on the prime to tear open. The package deal ought to have a shiny end and a lightly-textured border. Just lately considered one of our members of the family ordered some masks from Amazon that claimed to be made in Korea, however as soon as they arrived there have been 10 per package deal, signaling to us immediately they weren’t respectable. We returned them and ordered Pleased Day masks, which met the entire necessities.
Particular language within the nook of the package deal. For masks printed in Korean, the package deal ought to have “의약외품” or the phrase “quasi-drugs” in one of many corners of the packaging. However this will not be discovered on some KF94 masks printed in English. For example, Pleased Life’s masks bought on Amazon don’t embrace the lettering on its English-language package deal, however do have it on the Korean-language package.
MFDS certification on the web site. Most respectable masks makers will present proof of MFDS certification on their web site or for those who ask. For example, we emailed Lifesys AST Keep masks, and the corporate replied with a replica of their certificates inside a day.
