Sub High Efficiency Air Filter

 

The Sub High Efficiency Air Filter is a pre-filter of the High Efficiency Particle Air Filter (HEPA), which is designed to remove particles from the air, including dust, pollen, bacteria, viruses, etc. These filters typically filter out 90 to 99 percent of particles above 0.5 microns and are suitable for environments that require a high degree of cleanliness.

The replacement cycle of the Sub High Efficiency Air Filter depends on a number of factors, including:

Use environment: In high-pollution environments, the filter replacement cycle may be shorter.

Design resistance: When the resistance of the filter reaches 2 times the initial resistance of its design or operation (3 times for low resistance and high efficiency), it should be considered for replacement.

Time standard: Even if the above resistance standards are not met, the subHEPA filter is recommended to be replaced at least once a year to prevent performance degradation.

The replacement of the Sub-HEPA Filter is based on the following reasons:

Maintain efficiency: As the filter is used, its filter material will gradually accumulate dust and particles, resulting in a decrease in filtration efficiency.

Avoid excessive pressure drop: Increased filter resistance causes the system pressure drop to rise, which increases the fan's energy consumption and may even lead to premature system failure.

Maintaining air quality: Regular filter changes can ensure indoor air quality, reduce the impact on people's health, and protect sensitive equipment from contamination.

Therefore, it is very important to monitor the differential pressure indicator of the Sub High Efficiency Air Filter, which can help decide when to replace the filter. If there is no differential pressure indicator, it is recommended to make a replacement plan according to the manufacturer's recommendation and actual use to ensure the continuous efficient operation of the system and the health and safety of the indoor environment.
