So,how Does a HEPA Filter Work?
A HEPA filter is not like any regular air filter you typically put in your home. HEPA filters are pleated mechanical air filters that have a considerable thickness in order to capture the particulates. The pleats create a mat of fibers that are randomly arranged. The random, dense arrangement of fibers in the HEPA filter help to catch a range of particle sizes. As air particles pass through the air filter, they are caught by three mechanisms: diffusion, interception, and impaction.
When it comes to HEPA, there is a difference between “true” or “absolute HEPA” and “HEPA type.” While HEPA type filters effectively collect dust, lint, pet dander and pollen, they don't meet the same industry standards as true HEPA filters.
Today we take the example of HEPA 13filter and HEPA 14filter to show you how products of different industry standards differ.
HEPA 13 and HEPA 14 are two common specification grades that differ mainly in filtration efficiency and particle size that can be captured.
| HEPA 13 filter | HEPA 14 filter | |
| Efficiency | HEPA 13 filter efficiency of at least 99.97% , to capture the diameter of 0.3 micron particles in the air | the HEPA 14 filter has a higher filtration efficiency of at least 99.995% and is capable of capturing particles smaller than HEPA 13, including particles 0.3 microns and above. |
| Applicable | apply to the need for efficient air filtration environment, such as medical institutions, laboratories, etc. , can filter most of the fine particles and bacteria | apply to the air purity requirements of very high places, such as operating rooms, semiconductor manufacturing plants, can effectively filter fine particles and viruses. |
Overall, the main advantage of the HEPA 14 filter over the HEPA 13 filter is the higher filtration efficiency, the ability to capture smaller particles and more contaminants, therefore, it is more suitable in the environment with higher air quality requirements. However, the choice of HEPA filter specifications should be based on specific air filtration requirements and environmental requirements to decide.
In addition to these two products,as a professional hepa filter manufacturer in China,you can get different types of cleanroom hepa filter from our factory. Such as E11 Deep pleat HEPA filter,G3 Panel filter,M6 V bank filter,etc. Custom efficient filters are also possible.
