Industrial HEPA Filter H13 VS H14

Both of them are the highest classes of HEPA filters, and they are regarded as medical-grade quality filters because they are able to capture particles as fine as 0.3 microns at high efficiency.

However, there still exists some difference between H13 and H14.

H13 HEPA filter can block 99.97% of 0.3-micron air particles, which means the penetration rate is 0.03%. H14 HEPA filter is able to filter out 99.99% of 0.3 micron air particles, with a penetration rate is 0.01%.

In short, H14 HEPA filter is three times better than H13 HEPA filter in capturing airborne particles like dust, smoke, pollen, mold, etc.

Note: Europe’s H rating should not be confused with U.S. MERV ratings. Generally speaking, H13 and H14 is equivalent to MERV 17/18.

If you want to learn more detailed information about Filson industrial HEPA filter, you can look here to find your answers.

Can Bacteria Grow in Industrial HEPA Filter?

Of course, mold and bacteria can grow on it. They can be collected and released back into the air. Industrial HEPA filters can capture them but mold and bacteria can alive on the filter surface.

However, Filson industrial HEPA filter can prevent the reproduction of bacteria after special surface treatment.

How Long Do Industrial HEPA Filters Last?

Depending on air quality and environmental factors, Filson industrial HEPA filter should be changed every 6 – 12 months. If air quality is poor, the replacement time may be reduced to three months.

EN 1822: it is the valid standard for EPA, HEPA, and ULPA filters, and also an official standard in Europe and UAS.

ISO 16890: it is the internationally recognized classification and testing standard for air filters. The standard of ISO 16890 is a filter should capture at least 50% of particle sizes from the category.

What are the Key Performance and Characteristics of Industrial HEPA Filter?
  • Consistent performance: the whole system of the industrial HEPA filter needs to maintain high filtration efficiency and thorough purification
  • High air flow: it can ensure a high enough volume of air moving
  • No leakage: to prevent unfiltered air does not leak

How Many MERV Do I Need?

Generally speaking, for home requirements, the MERV rating between 8 – 10 is enough. For

higher requirements like hospital, food processing, pharmaceutical production, etc, the MERV rating can be up to 17. It also depends on the materials airborne.

If you are still confused about it, Filson has professional workers who will help you choose the best suitable industrial HEPA filter for your applications.

How Industrial HEPA Filters Work and What are they Consist of?

Industrial HEPA filters usually remove particles through direct impact or complex diffusion systems, which allows them to effectively eliminate a greater amount of particles.

Most industrial HEPA filter is made of interlaced glass fiber, which creates a fibrous web. It also contains metal separators to maintain uniform spacing and a larger surface area.
