PM 2.5 filter mask is a mask that features a cloth pocket with replaceable activated carbon filter inserts. The mask can sometimes be made from thin foam and feature a vent system for easier breathing (some provide better inhaling and others provide a better exhaling system) and better isolation of the nose and mouth from the particles. The mask allegedly helps dissipate your breath nicely and shouldn’t cause breathing troubles, irritation of nose, throat, or even eyes. There isn’t usually a problem with condensation, so people don’t have a problem wearing a PM 2.5 filter mask with glasses. These masks often come with filters that feature activated carbon or activated bamboo pulp to prevent the particles from entering your ai. Some masks come with adjustable ear straps, while other, high-quality PM 2.5 masks come with straps that go behind the neck to ensure better fitting and tightness where it is needed the most (around the nose and the chin).These masks can be used without the PM 2.5 filter because they often feature several layers of protective cotton that can be effective for general use.
What Does PM 2.5 Stand For?
PM 2.5 stands for the term ‘fine particulate matter’ and represents air pollutant particles that are up to 2.5 µm in size and composition (Aerosol Aerodynamic Diameter is less than 2.5 µm). These can be liquid or solid particles that can be fine and ultrafine. PM 2.5 particles occur in cases of burning fuel, automobile exhaust, burning of garbage and landfill, processing and melting of metals, as well as chemical reactions that occur in the atmosphere.
They are also the primary contributors to the creation of smog, which has become an increasingly hazardous problem in hundreds of cities around the world.PM 2.5 particles include sulfates, nitrates, ammonia, carbon monoxide, and many other heavy metal particles that can be hazardous to our overall health.When inhaled, these particles can travel to the lungs and other organs, causing most commonly heart and lung disease. These particles can cause harm to anyone, but children and the elderly are most sensitive to the effect of PM 2.5 particles. Check here pm 2.5 filter effectiveness
How Long Can You Use ?
It is stated that pm2.5 filter masks are disposable. Usually, the masks come with approximately 5 filters, that can be effective for 1 to 3 days, which could amount to 1 to 2 weeks of occasional use.It is also stated that filters can be changed once every week, so a mask should be lasting you for a month or two, depending on the frequency of use.
Can Protect From Coronavirus?
There isn’t evidence that a PM 2.5 filter mask can protect you from COVID-19 What we can say is that the findings have shown the coronavirus (SARS-CoV-2) to be much smaller than PM 2.5 fine particles. In fact, it is believed that coronavirus is only 1/25 of PM 2.5, and definitely smaller than bacteria. Alongside the mask, the protective measures against COVID-19 include general hygiene, regular hand washing, social and physical distancing, avoiding larger groups of people, avoiding hugging/kissing, coughing and sneezing in public, etc.
