What Types of Masks Filter out PM 2.5 Particles?

Protection against germs, bacteria, and viruses is one of the best things that people have focused on. During this pandemic, people have definitely learned a lot about personal protective equipment, N95 masks, and N95 respirators. There is a lot of information out there that people should know about the masks and the kind of bacteria and environmental elements that they provide protection from.

With that, this article aims to provide information on the different types of masks and the different types of information available about what they filter out.

Filter Out Particles

There are a lot of things that you can filter out. There are also a lot of filters that are associated with the personal protective equipment, N95 masks, and N95 respirators but these filters are nothing compared to what the personal protective equipment, N95 masks, and N95 respirators with the PM 2.5 particle filter can offer the individual.

There are many different kinds of PM 2.5 filters. They come in many forms and shapes. Some are very high in quality while others are very low in quality. It is required for individuals to have a close look at both the material and the structure that is essential for their protection. 

What is PM 2.5?

If you have been reading some information about personal protective equipment, N95 masks, and N95 respirators, you have probably heard and read about the PM 2.5. There are some N95 masks that can filter out this kind of pollutant, you probably already know this. There are also already many different kinds of personal protective equipment, N95 masks, and N95 respirators that people should know about. 

With that, it is important to find the necessary information about the product and everything that the individual would need to know about and they are the following:

  • It is called PM 2.5 because it means Particulate Matter on the size of 2.5 micrometers. While the pollutants in the air often vary in size and some are differently shaped, they cause damage to one’s health. 
  • PM 2.5 is considered as the smallest but it does not mean that it is good for the individual. The particles are so small that they can only be viewed under a microscope and even with their size, they are much more deadly than the big sized ones.
  • PM 2.5 may come from many different sources such as forest fires and coal burning, combustion in vehicles and machinery, industrial processes, particularly those involving coal, sources inside the home, such as candles, lamps, and fireplaces, emissions from power plants and chemical processes in the atmosphere which happen when gasses and other pollutants from power plants interact.

Materials Making Up PM 2.5

PM2.5 filters are often made with the highest quality carbon. They are often made up of three non-woven materials that work together to create the barrier that the individual needs for his protection. There is the melt-blown fabric, spun-bond fabric, and activated carbon fabric. The following are their meanings:

  • Non-woven fibers act as a physical barrier against microscopic particulates while also providing an electrostatic barrier to stop aerosolized nano-particles.
  • Melt-blown fabric is perhaps the most important part of a filter that aims to be classified as PM 2.5; and
  • In most cases, there are also come activated carbon fabrics in the material that makes up the product. This part aims to trap particulates via a process called adsorption, and also serves as an antibacterial and deodorizer.

What Types Of Masks Filter Out PM 2.5?

There are many different types of masks that individuals should know about but the more important aspect of the mask that not a lot of people talk about is the PM 2.5 filter. Not all filters are made equal and people need to know that filters are typically certified to a standard that aims to measure the filtration percentage. This means that the mask that comes with a filter that is usually measured in terms of the percentage of the particles filtered and that which can filter out at least 0.3 microns of particles in the air are already good. 

N95 masks, N95 respirators, or any mask that comes with an N95 certification is definitely one of the best that can filter out the micron particles of their size. The filter is certified and it can filter out 95% of the particles at 0.3 microns in size. As long as the N95 mask comes with the certifications on the following tests, the end user is sure that it can filter out the particulates that is the size of 2.5 microns:

  • Particle Filtration Efficiency;
  • Anti Bacterial Efficiency;
  • Viral Filtration Efficiency; and 
  • Breathing Resistance.

The N99 masks are also good in terms of filtering out these kinds of particles since they can offer filters with a N99 rating, which can filter out 99% of particles at 0.3 microns in size

Trust The Process

It is important for people to also know that they can trust the process when it comes to the NIOSH certification of the N95 masks and the N95 respirators. As long as you see one that can work based on your needs and has the NIOSH certification, you can trust it and what it looks like. You should definitely trust the process done for the certification.
