High-performing H10/H11/H12/H13/H14 bag-type Air Filters, namely, High performance H10 to H14 Bag air filters, belong to the category of high efficiency filters (HEPA), with different filtration efficiency and characteristics. The following is a detailed explanation of these filters as well as intermediate and secondary air filters:

1. High efficiency filter (HEPA)
High-efficiency filter (HEPA) is a device that can filter out small particles in the air, and its filtration efficiency is very high. HEPA filters are commonly used in environments that require high cleanliness, such as hospital operating rooms, laboratories, semiconductor production plants, and so on.

Filtration level: The filtration level of HEPA filters is usually expressed as H10 to H14, where H14 is the highest level. These grades represent the filtration efficiency of the filter for particles larger than 0.3 microns, such as H10≥85%, H11≥95%, H12≥99.5%, H13≥99.99%, and H14≥99.995%.
Type: HEPA filter includes a variety of types, such as separator high efficiency filter, no separator high efficiency filter, combined high efficiency filter, liquid tank type high efficiency filter, etc. Bag filters are also a common form of HEPA filters.
Characteristics: HEPA filter usually has the characteristics of stable structure, large air volume, small resistance, high dust capacity, and repeatable clean use. They are manufactured using a hot-melt process that reduces the risk of leakages and are equipped with efficient filter media such as fiberglass filter paper.
Two, bag type air filter
Bag air filter is a kind of filter material made into a bag and installed in the filter frame filter. This design allows for a larger filtration area, thereby improving filtration efficiency and dust capacity. Bag type air filter is widely used in various industrial fields, such as steel, cement, chemical and so on.

Three, medium effect filter
Medium effect filter is a kind of filter whose filtration efficiency is between primary effect filter and high efficiency filter. They are mainly used to capture 1-5 microns of particulate dust and various suspended particles, and to protect the downstream HEPA filter from pollution by large particles. Medium effect filter is usually used in air conditioning system, ventilation system and other occasions.

Four, secondary air filter
Secondary air filter is not an independent filter type, but a relative concept. In some cases, to further improve the cleanliness of the air, additional filter layers may be placed before or after the HEPF, and these filter layers may be referred to as secondary air filters. Their role is to further remove small particulate matter or specific pollutants from the air.

Fifth, comprehensive application
In practice, high performance H10 to H14 bag air filters may be used in combination with intermediate or secondary air filters to form a multi-level filtration system. Such systems are able to remove pollutants from the air more effectively and provide a higher level of cleanliness.

Please note that while the above information provides detailed information on high performance H10 to H14 bag air filters, medium efficiency filters, and secondary air filters, the specific application scenario and selection need to be evaluated and selected according to the actual situation.
