Primary/medium/high efficiency filters are used to remove suspended particles in the air and should be configured accordingly according to the different performance requirements of different occasions.

Primary filters are suitable for the front end of the air conditioning system to initially filter larger particles of dust and impurities.

Medium efficiency filters are suitable for secondary filtration in air conditioning systems to further filter medium-sized particles and serve as pre-filters for high-efficiency filters to protect the next level of filters in the system and the system itself.

High efficiency filters are often used at the end of air conditioning systems, and are also an important component of clean room FFU, clean benches, laminar flow transfer windows and other air purification equipment. Based on the many advantages of high efficiency filters, their application range is very wide, and they are used in electronic semiconductors, biopharmaceuticals, aerospace, etc., and their appearance has also made great contributions to these industries.

The main factors affecting the performance of filters are filtration efficiency, resistance, penetration rate, dust holding capacity and air volume, etc. Filters with high efficiency, low resistance, large dust holding capacity, large air volume, easy installation, energy saving and consumption reduction should be selected as much as possible. This is the need for economic analysis that comprehensively considers one-time and multiple times and energy efficiency ratio when selecting filters.

The performance of the filter directly determines the removal efficiency of air pollutants. In order to ensure the quality and performance of the filter, the filter must be strictly tested. In Esky Purify's high-quality air filter system solution, the detection of the filter is regarded as an important part and advanced testing equipment has been introduced.
