There are various types of masks available on the market, made from different materials for users to choose from. Some masks are affordable, convenient, and easy to find but they only filter large dirt particles. To filter fine dust, specialized masks are produced to protect you and your family, namely the 2.5PM mask. Let's delve into the details of this mask in the article below.
Exploring 2.5PM Masks
What are 2.5PM Masks?
2.5PM masks feature a PM2.5 filter made from the same advanced material used for N95 and KN95 masks, in addition to an activated carbon layer. Because the 2.5PM filter has mechanical and electrostatic layers, it can block even the smallest nano particles. 2.5PM masks have high filtration efficiency against airborne particles, protecting against pollutants smaller than 2.5 micrometers. This size is only one-tenth the size of a human hair.
How many types of 2.5PM masks are there?
Currently, there are two types of 2.5PM masks available on the market:
- Separate 2.5PM filter masks: The 2.5PM filter can be easily removed and inserted into the mask. Users can replace the filter if needed.
- Integrated 2.5PM filter masks: The 2.5PM filter layer is integrated into the mask and cannot be removed by users. However, the technology behind these masks is relatively costly.
Effects of 2.5PM masks
- Offering both solid protection and greater comfort compared to medical masks and N95 masks
The filter of 2.5PM masks has the ability to block most dust particles in the air. Additionally, it provides a sensation of easier breathing compared to tightly sealed medical masks like N95 or KN95 masks.
- 2.5PM masks are incredibly convenient
Disposable flat-shaped 2.5PM filters take up less space than standard gas masks. They maintain effectiveness for several years, allowing users to continuously use them for 16-24 hours.
Replacement PM2.5 filters can be used when air quality is poor or in crowded places. PM2.5 filters are compact and easy to carry around.
How does a 2.5PM mask work?
Standard 2.5PM masks typically have a filter with 3 different non-woven fabric materials: bonded fiber, melt-blown fabric, and activated carbon fabric.
Counterfeit filters often use two layers of bonded fiber instead of two layers of melt-blown fabric, resulting in higher cost and more complex production processes for melt-blown materials. This leads to reduced both physical and electrostatic filtration.
Melt-blown fibers act as a physical barrier against ultrafine particles and provide an electrostatic barrier to prevent sol-gasified nano particles. Melt-blown fabric is softer and less rigid than spunbond fabric. It is akin to silk paper, contrasting with the glossy elasticity of bonded fibers. Activated carbon fabric offers numerous benefits, including acting as a natural odor remover and antibacterial agent alongside its electrostatic properties. Activated carbon is detected through H20 or Burn tests.
Masks equipped with a proper PM2.5 carbon filter tested to N95 standards help effectively reduce the quantity of bacteria and particles in the air.
