ePM1

This filtration level significantly improves indoor air quality and helps protect sensitive equipment and occupants.

Typical Particle Size

• PM1 (≤1 µm)

Available Efficiency Classes

• ISO ePM1 50%

• ISO ePM1 80%

Key Features

• Effective removal of very fine and ultrafine particles

• Improved HVAC system cleanliness

• Reduced dust deposition on coils and ducts

• Suitable for high-performance HVAC systems

Typical Applications

• Hospitals and healthcare facilities (general areas)

• Data centers and technical rooms

• Laboratories and clean production environments

• Commercial buildings with high IAQ standards

Why Choose ISO ePM1 Filters

ISO ePM1 filters offer advanced fine particle control while remaining compatible with high-airflow HVAC systems. Higher efficiency classes are selected based on IAQ targets and system capacity.

FAQ

What is the difference between ISO ePM1 50% and 80%?

ISO ePM1 80% provides significantly higher removal of PM1 particles and is typically used in more sensitive environments.

Are ISO ePM1 filters equivalent to HEPA filters?

No. ISO ePM1 filters improve fine particle control but do not meet the efficiency requirements of HEPA filters.

Do ISO ePM1 filters increase energy consumption?

Higher efficiency may increase pressure drop slightly, but modern filter media designs help maintain energy-efficient operation.
