It is especially the case for facemasks and respirators, as they can minimize the inhalation or spread of droplets and aerosols. Considering that these air filters may shed micrometer fibers during the cutting and folding processes, it is recommended that these filters should be inserted in multiple layers of fabrics when manufacturing facemasks or respirators.ĭue to the 2019 coronavirus disease (COVID-19) outbreak, the global demand for personal protective equipment (PPE) has surged and created a severe shortage across the world ( CDC, 2020). The results illustrate that multiple layers of household air filters are able to achieve similar filtration efficiencies compared to the N95 material without causing a significant increase in flow resistance. The flow resistance across these filter materials is measured as an indicator of the breathability of the materials. The experiments were conducted under different face velocities to study its influence on size-dependent filtration performances. In this study, we comprehensively evaluated the overall and size-dependent filtration performances of non-medical materials. Moreover, there are a series of non-medical materials available on the market, such as household air filters, coffee filters, and different types of fabrics, which may be useful when facemasks and respirators are not available. Centers for Disease Control and Prevention (CDC) recommends that “in settings where facemasks are not available, healthcare personnel might use homemade masks (e.g., bandana, scarf) for the care of patients with COVID-19 as a last resort.” Although aerosols and droplets can be removed through the fibers of fabrics through a series of filtration mechanisms, their filtration performances have not been evaluated in detail. Because the coronavirus can transmit through droplets and aerosols, facemasks and N95 respirators that require complex certification, are urgently needed.

While any unused medical-grade or N-95 masks we own should be donated to healthcare workers coming into direct contact with sick patients, this multi-benefit mask may still help slow the spread - especially among those who are asymptomatic!Ĭheck our latest news in Apple News Follow Usĭisclaimer: While we work to ensure that product information is correct, on occasion manufacturers may alter their ingredient lists. This mask comes with two, by the way! These filters may help protect you from breathing in dust, pollen, smoke, vehicle exhaust, hazy air and more. Things only get more impressive from there.īeneath the soft cotton layer on the outside is a space to slip in activated carbon filters. Know how things get super humid super fast when you cover up your nose and mouth? This valve may help prevent that heat and moisture buildup, along with preventing CO2 accumulation. You’ll immediately notice the respiratory valve on the outside. It’s clear even visually that this mask is heavy-duty when it comes to air filtration. Get the PM2.5 Activated Carbon Filter Mask for just $9 at Amazon with free shipping! Get it as early as May 1, 2020!
