What Does HEPA Mean?
HEPA stands for "High Efficiency Particulate Air" or "High Efficiency Particulate Arrestance". It is a type of pleated mechanical air filter. This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). And there are two main types we might heard of in our daily life, the HEPA 13 and 14 filters, they have similar functions while different applications.
What is HEPA 13 Filter?
HEPA 13 filter is a high-efficiency particulate air filter that can remove 99.95% of all particles in the air measuring 0.3 microns in diameter. It is considered a medical-grade filter and is one of the highest tiers of HEPA air filtration. This makes it extremely effective at capturing small particles that are harmful to human health, such as viruses and bacteria.
Furthermore, the 0.3 micron size is the most difficult size of particle to capture, known as the most penetrating particle size (MPPS). Therefore, the expressed percentage is the filter’s worst case efficiency, and particles that are larger than 0.3 microns are trapped with even higher efficiency.
HEPA 13 filter can help improve indoor air quality in homes by capturing a wide range of airborne particles, including pollen, dust, pet dander, and mold spores. It can also capture smaller particles such as bacteria and viruses, which can be beneficial for people with allergies, asthma, or other respiratory conditions. Additionally, a HEPA 13 filter can help reduce unpleasant odors and improve the overall air freshness in your home.
What is HEPA 14 Filter?
HEPA 14 filter is a type of high-efficiency particulate air filter that is designed to capture at least 99.995% of particles that are 0.1 microns in size or larger. This means that HEPA 14 filters are even more efficient than HEPA 13 filters, which capture at least 99.97% of particles that are 0.3 microns in size or larger.
HEPA 14 filters are typically used in industrial settings, such as clean rooms, laboratories, and medical facilities, where extremely high levels of air purity are required.
Difference Between HEPA 13 and HEPA 14
HEPA 13 and HEPA 14 filters are both high-efficiency particulate air filters that are designed to capture a high percentage of airborne particles. However, there are some differences between the two types of filters.
The main difference between HEPA 13 and HEPA 14 filters is their efficiency level. HEPA 13 filters are designed to capture at least 99.95% of particles that are 0.3 microns or larger, while HEPA 14 filters are designed to capture at least 99.995% of particles that are 0.3 microns or larger. This means that HEPA 14 filters are slightly more efficient than HEPA 13 filters.
Another difference between the two filters is their intended use. HEPA 13 filters are commonly used in residential and commercial air purifiers, vacuum cleaners, and HVAC systems, while HEPA 14 filters are typically used in specialized applications such as cleanrooms, hospitals, and laboratories where ultra-clean air is required.

Overall, HEPA 13 vs. HEPA 14, both filters are highly efficient in capturing airborne particles, but the choice between the two will depend on the specific needs of the user and the intended application. HEPA 13 filter with 0,3 microns filtering size is powerful for home use. While HEPA 14 filter with 0.1 microns filtering size is for industry using. If you are consider to purchase one for home, here are options for you from MSPure, one of the best air purifier manufacturers in America.
