What Is a HEPA Filter? Industrial HEPA Filter Selection Guide

What a HEPA filter is, how it works, what it does and does not do, where industrial HEPA filters are used and how to select class and seal.

The main types of filters used in industry, from panel and bag to compact, HEPA, activated carbon and custom sizes, and how to select between them.

What an industrial air filter is, how multi-stage filtration works, the three stages, filter types, selection criteria and what a quotation needs.

How EN 1822 classifies HEPA filters: the MPPS concept, leak testing and the H13 to H14 classes used in cleanroom and hospital projects.

How often HEPA filters should be replaced, what shortens their service life and how to keep filtration efficiency stable in industry.

What an H14 HEPA absolute filter is, how it differs from H13, where it is used in cleanrooms and hospitals, and how to select frame and seal.

Compare H13 and H14 HEPA filters by MPPS efficiency, leakage limits and pressure drop, and see which class an application actually needs.

What HEPA filter testing covers: factory classification versus installed integrity testing, how PAO and DOP differ, and how to read a test report.

Compare HEPA and ULPA filters by EN 1822 efficiency, MPPS, pressure drop and applications, and learn when each class is the right choice.

MPPS is the particle size a filter captures least efficiently. Learn what MPPS means, why HEPA filters are rated at it and how it sets the class.
