What’s the Difference Between PM2.5 and N95?
Typically, PM2.5 are particulate matters in the air comprising dust, soil, pollen, and various harmful chemicals. The size of these particles is thinner than a single human hair. That’s why PM2.5 masks are designed in such a way to capture these particles from entering the respiratory system. But the Coronavirus viruses are much smaller than these pollution particles, with a range between 0.06 to 0.14 microns in size.
Due to this fact, it’s safe to say that N95 masks are effective against blocking large pollution particles as well.
However, some factors differentiate PM2.5 masks and N95 medical respirators.
Material
PM2.5 masks are made of non-woven fabric, activated carbon, or cotton fabric. The tight-fitting and knitted diameter of several micrometers prevents particulate matter from damaging your respiratory system.
In comparison, N95 medical respirators are made of a material called polypropylene. Polypropylene is a synthetic plastic made out of fossil fuels, such as oil.
Gap
PM2.5 masks have been in use for years around Asia. Due to the high amount of pollution in the air, these masks are also called air filter masks, smog masks, reusable dust masks, etc. And since they are manufactured with a tight-fit in mind, there is little to no gap present while wearing. This feature is highly noticeable compared to surgical masks, which have a slight gap, leaving room for breathing.
N95 medical respirators provide a tighter fit than surgical masks, but they are loosely bounded than PM2.5 masks. Of course, the difference also varies whether the PM2.5 mask comes with a filter or without.
Breathing
There’s a reason why N95 respirators are recommended for medical professionals only. That’s because wearing a respirator for a longer duration can affect your heart and lungs, especially in a non-industrial setting. That’s why FDA only recommends using N95 masks by medical personnel.
A fitted particulate mask, i.e., PM2.5 mask, serves as the best alternative to avoid increased exertion with breathing. Although they aren’t as effective as N95 respirators in blocking out the fine particle Coronavirus, there is still some level of protection to get you through the day without straining your lungs unnecessarily.
Caution: People with breathing difficulties, such as asthma, or sinusitis may experience inhalation resistance after switching to PM2.5 masks. That’s why members of sensitive groups must consult a medical professional first before using PM2.5 masks.
