In air purification systems, why is it necessary to install primary and medium filters instead of directly using high-efficiency filters? This 'three-level filtration' structure is a scientifically designed protection system created by KLC, based on considerations of aerodynamics and operational costs.
KLC PRE-FILTER SERIES
As the first line of defense in the system, it primarily intercepts large particles greater than 5μm, such as hair, insects, and gravel. KLC installs it at the front end of the air handling unit to prevent large particles from physically damaging subsequent filter media and to reduce system load from the source.
▲ KLC PRE Filter
KLC Medium Filter Series
Responsible for capturing fine particles in the 1–5μm range. This stage is crucial. KLC medium-efficiency products can effectively capture medium-sized dust that may clog high-efficiency filters, significantly extending the service life of downstream high-efficiency filters from a few months to 1–2 years, ensuring stable system operation.
▲ KLC Medium Filter
KLC HEPA Filter Series
Installed at the air outlet of the cleanroom, it targets the ultimate interception of ultrafine particles and microorganisms below 0.3μm. KLC high-efficiency products ensure that the air entering the room strictly meets the designated cleanliness level and act as the final barrier for maintaining core cleanroom performance indicators.

The core of adhering to the three-level filtration logic lies in economic benefit and system safety. Without the first two protective stages, expensive high-efficiency filters would quickly become saturated and fail, leading to high replacement costs and risks of production downtime. Regularly replacing low-cost KLC primary and medium filters to protect the core components is the most economical strategy for enterprise operations. As a professional provider of comprehensive air purification solutions, KLC strives to create long-lasting, low-consumption clean spaces for every customer.
