What are Primary (Coarse) Filters?

Primary (coarse) air filters are the first stage of an air filtration system. Their purpose is to remove larger airborne contaminants such as dust, lint, fibres and pollen before the air reaches finer secondary or HEPA filters.

Using an effective primary filter helps to:

• Extend the service life of downstream filters.
• Reduce maintenance costs.
• Maintain airflow through HVAC and ventilation systems.
• Improve the overall efficiency of multi-stage filtration systems.
