Health (NIOSH) recently provided criteria for a new standard of masks meant for nonmedical workplace settings. Masks tested to this standard can meet one of two levels: Workplace Performance and Workplace Performance Plus. The specification uses ASTM standard F3052-21, which tests masks for filtration of submicron particulates and wearer breathability, but NIOSH adds another metric for leakage, called the leakage ratio.The leakage ratio is tested using a modified version of 29 CFR 1910.134, the same standard used to test N95 masks, among other OSHA-approved respirators. To be considered a Workplace Performance mask, a mask must have a leakage ratio of greater than or equal to 5, a filtration efficacy of submicron particles greater than or equal to 50 percent, and compliance with ASTM F3052-21’s Level 1 breathability metric. Masks with leakage ratios greater than or equal to 10 (the higher, the better), Level 1 breathability, and greater than or equal to 80% particulate filtration meet the standard of Workplace Performance Plus. NIOSH's standard for nonmedical workplace masks. Credit: CDC/NIOSH NIOSH's standard for nonmedical workplace masks. Credit: CDC/NIOSH This is a newer, optional standard for consumer mask manufacturers to use, so the list of masks using this standard is still small. Results from the tests can be found on the CDC’s website. We’ve chosen a couple of masks from this list as our top picks above, taking into account all three aspects of NIOSH’s criteria.A note on the science of face masks Even in the 14th century, we had an idea (albeit the wrong one) that disease spread could be limited through mask use. Just be glad you don't have to wear this. Even in the 14th century, we had an idea (albeit the wrong one) that disease spread could be limited through mask use. Just be glad you don't have to wear this. As a disease that has only come to our knowledge in the past couple of years, the epidemiology and pathology of COVID-19 is still relatively nascent compared to pathogens we've had decades, or even centuries, to study. As much as we at Ars wish we could contribute Legitimate protection in the hands of health care workers. Within those EUAs are lists of imported disposable filtering facepiece respirators (FFRs)—that is, disposable masks—that the FDA approved for use in health care settings.The lists predominantly feature popular models like China’s KN95 and Korea’s KF94 face masks, sold by various brands and tested for filtration efficacy by the NIOSH National Personal Protective Technology Laboratory (NPPTL). Using a modified version of NIOSH’s filtration standard for N95 masks, the tests focused solely on filtration efficacy, not fit and durability (among other tests), as NIOSH-approved N95s are typically tested in noncrisis circumstances.Masks that were found to meet their claims of a minimum 95 percent particulate filtration for particles 0.1μm or bigger were approved for use in health care settings due to the crisis-level need for PPE. Though many were tested, not all were approved. As of July 6, 2021, those that didn't make the cut were banned from use in health care settings.The revocation of this EUA means that medical institutions must now seek only NIOSH- and FDA-approved surgical N95 masks for their personnel. What that means for the public is that, at this time, there is no longer cause for concern with potentially taking away N95-equivalent masks from health care workers. Essentially, any KN95s, K94s, or other N95-equivalents that tested well on these lists are fair game for consumers to buy. While stock on NIOSH-approved N95s has also improved, using them exclusively for day-to-day activities is both impractical and unnecessary in most cases. Non-health care workers should never purchase surgical N95 masks that are specially labeled as such. But having a stock of nonsurgical N95s for particularly risky situations where social distancing can’t be observed, like taking public transportation or other similarly fraught indoor activities, is advisable for the general public. In particular, N95s are recommended in all situations for those who are over the age of 60, those who have underlying conditions, those caring for someone who is ill with COVID-19, or people who are themselves feeling unwell, according to WHO and CDC guidance.If you’re regularly in high-risk situations, like if you

The Honeywell NIOSH-Approved P100 Respirator Mask w/ Exhalation Valve for Airborne Particulates provides 99.97% filter efficiency against all particulate aerosols. This includes work-related irritants like dust, sawdust and airborne allergens. The breathing mask's filter media is designed to resist humidity for comfortable performance in most environments. This P100 disposable mask comes equipped with an exhalation valve that allows hot air to exit the respirator for increased comfort. The two-strap construction allows for quick donning, while the adjustable nose bridge means one size will fit most faces. This face mask is a P class respirator that is NIOSH approved for use with solid and liquid particulates, excluding oils. Each package includes (one) disposable P100 respirator. Workplace & Home ProtectionAirborne irritants can be a hazard at both your home and workplace. This includes dust from work-related activities like grinding, sanding, woodworking, drywalling and masonry, but also simple home tasks like yardwork and sweeping. Honeywell NIOSH-Approved P100 Respirator Masks provide 99.97% filter efficiency against solid and liquid particulates in the air. N: This is a Respirator Rating Letter Class. It stands for “Non-Oil” meaning that if no oil-based particulates are present, then you can use the mask in the work environment. Other masks ratings are R (resistant to oil for 8 hours) and P (oil proof). 95: Masks ending in a 95, have a 95 percent efficiency. Masks ending in a 99 have a 99 percent efficiency. Masks ending in 100 are 99.97 percent efficient and that is the same as a HEPA quality filter. .3 microns: The masks filter out contaminants like dusts, mists and fumes. The minimum size of .3 microns of particulates and large droplets won’t pass through the barrier, according to the Centers for Disease Control and Prevention (CDC.) Material: The filtration material on the mask is an electrostatic non-woven polypropylene fiber. Valve: Some disposable N95 masks come with an optional exhalation valve. “The presence of an exhalation valve reduces exhalation resistance, which makes it easier to breathe (exhale,)” according to the CDC.

Properly, the gas inside the pipe would have expanded and escaped, forming bubbles at the inlet and outlet of the heat pipe due to the increase in gas temperature. During the experiment, no bubbles were observed in the heat pipe, indicating that the heat pipe printed using SLM technology had good airtightness. 5.2. Quality Inspection of Heat Pipe PrintingThe industrial performance of the EOSM280 printer was good, and the printed heat pipe and the designed model were almost identical on the surface. However, due to the small size of the heat pipe and its application in precision instruments like microsatellites, high-performance requirements were placed on it [28]. However, selective laser melting (SLM) technology has some drawbacks, such as the challenging removal of powder residue and potential structural deformations [29,30]. To ensure that the printed products are fit for use, before proceeding with further experiments, we used a CT scanner to inspect its internal structure [31,32]. The inspection results are depicted in the following figure, Figure 9. According to the structure of the picture, it could be found that the channel structure of the heat pipe was the same as the designed structure, and the middle part had not undergone deformation, indicating that SLM technology achieves good performance in producing small heat pipes and could be used for the next step of our experiments. 5.3. Heat Pipe Vacuum Environment ExperimentAs the heat pipe was primarily intended for use in the space environment within microsatellites, the experiments needed to be conducted in a vacuum. According to the experimental setup, the heat pipe was suspended inside a vacuum chamber, as illustrated in Figure 10, for testing. Figure 11 provides a physical representation of the experimental setup.The experimental process involved first filling the heat pipe and ensuring its seal. Then, temperature sensors (thermocouples) were
