Industrial type, the best performing HEPA air filter – tested and ranked!
In this guide, you will find a list of the best and most efficient air filters, along with their actual test data. You will also learn about the typical form of regular high-efficiency filters (HEPA filter)
Aluminum partition HEPA filter Test Data Analysis :
Premium Efficient Filtration: The Aluminum partition HEPA filter captures 99.97%~ 99.997% of substance as small as 0.3 microns, making the air around you fresher. The thickness is usually greater than 150mm.
Frame: Galvanized Iron/stainless steel
Separator: Aluminum foil/Offset paper
Filter Media: Glass fibre
Gasket: PU foam seal/CR seal strip
Operation Conditions: <80%/100%RH, <80 ℃

Gasket: Gel
Operation Conditions: ≤80%/100%RH,40℃
| Product name | Liquid tank filter |
| Efficiency | H14 (0.3μm@ 99.995%) |
| Size | 670x670x90mm |
| Rated Air velocity （m/s） | 0.45 |
| Air volume CFM (m³) | 970 |
| Initil P.D (Pa) | 75 |
| Final P.D (Pa) | 265 |
V bank HEPA Filter Test Data Analysis :
A V-bank HEPA filter features a unique V-shaped design that provides a large filtration area and low airflow resistance. It efficiently captures 99.97% of airborne particles as small as 0.3 microns, including dust, bacteria, and viruses. Ideal for strict air purity requirements in HVAC systems and cleanrooms.
Frame: ABS/Galvanized Iron/Aluminum/Stainless steel
Spacers: EV
Filter Media：Glass fibre
Gasket：PU seal strip
Operation Conditions: Max 80%, 80 ℃
| Product name | V bank filter |

| Rated Air velocity （m/s） | 0.45 |
| Air volume CFM (m³) | 567 |
| Initil P.D (Pa) | 30-50pa |
| Final P.D (Pa) | 265 |
FAQ on True HEPA Air Filter
What Does “True HEPA” Mean?
A truly efficient air filter is one that has undergone independent testing and has received certification, capable of removing tiny particles as small as 0.3 micrometers in diameter. The efficiency of H13 is 99.97%, and that of H14 is 99.997%.
Can Industry HEPA Air Purifiers Remove Odors and VOCs?
While HEPA filters are highly effective at capturing airborne particles such as dust, pollen, and pet dander, they are not designed to eliminate gases, odors, or volatile organic compounds (VOCs). For these types of pollutants, it’s essential to choose an air purifier that includes a dedicated Activated carbon filter.
How long does a True Industry HEPA filter last?
Under normal conditions, industrial high-efficiency air filters can typically be used for 9 to 12 months when operating normally.
However, a pre-filter is required, which can filter out large particles of dust, thereby extending the service life of the high-efficiency filter.
The pre-filter page can be used for cleaning.
