ISO ePM10 Filters

About ISO ePM10 Filters

ISO ePM10 filters are used to remove airborne particulate matter up to 10 micrometers in size.

Under ISO 16890, this classification applies to filters that provide measurable performance against particles in the PM10 range, making them suitable for many commercial and industrial air filtration applications.

These filters are often used where systems require a step above coarse filtration for better control of dust, pollen, and similar airborne particles, while still maintaining reasonable pressure drop and operating efficiency.

Typical Particle Size

ISO ePM10 filters are designed to target particles:

• ≤10 µm

These may include:

• larger fine dust
• pollen
• mold-related particulate matter
• airborne debris smaller than coarse particles
• particles commonly found in building ventilation air

Key Features

• Improved performance compared with ISO Coarse filtration
• Effective removal of dust and pollen-sized particles
• Suitable balance between efficiency and airflow
• Helps reduce particulate loading on downstream filters
• Supports cleaner air in commercial and industrial settings
• Practical for broad HVAC pre- and mid-stage filtration use

Typical Applications

ISO ePM10 filters are commonly used in:

• Commercial HVAC systems
• Office buildings and public facilities
• General industrial ventilation systems
• Air handling units in mixed-use buildings
• Pre-filtration before finer filtration stages
• Buildings requiring better dust control than coarse filtration alone

Selection Considerations

ISO ePM10 filters are generally selected when better particulate removal is needed than ISO Coarse filters can provide, but full fine-particle control is not necessary. They are often used in applications focused on dust reduction, pollen control, and improved ventilation cleanliness.

When selecting ISO ePM10 filters, important factors include:

• type of airborne contaminants present
• required airflow and pressure drop balance
• building use and occupancy level
• local outdoor air conditions
• downstream filtration design
• expected replacement interval

These filters are often used as either upgraded pre-filters or intermediate filtration stages.

ISO ePM10 vs Other ISO 16890 Grades

ISO ePM10 filters provide finer filtration than ISO Coarse filters, but they are not as fine as ISO ePM2.5 or ISO ePM1 filters. They are well suited to applications where moderate particulate control is needed without the higher resistance or cost associated with finer filtration stages.

This makes them a practical option for many HVAC systems focused on everyday air quality improvement.

ISO ePM10 FAQ

What does ISO ePM10 mean?

ISO ePM10 refers to a filter classification under ISO 16890 for filters that are effective at capturing particulate matter up to 10 micrometers.

Where are ISO ePM10 filters commonly used?

They are often used in commercial HVAC systems, office buildings, industrial ventilation systems, and as pre- or intermediate filtration stages.

Are ISO ePM10 filters better than ISO Coarse filters?

Yes, for smaller particle control. ISO ePM10 filters are designed for particulate matter up to 10 micrometers, while ISO Coarse focuses on larger particles.

What is the difference between ISO ePM10 and ISO ePM2.5?

ISO ePM2.5 filters are designed for finer particles and are typically used where higher indoor air quality performance is required.

Can ISO ePM10 filters be used in multi-stage systems?

Yes. They are commonly used before finer filters such as ISO ePM2.5, ISO ePM1, or HEPA filters.
