Microfiber AHU Filter

About Microfiber AHU Filter

The Microfiber AHU Filter is a high-efficiency air filter designed for use in Air Handling Units (AHUs) to improve indoor air quality and protect downstream HVAC components. Constructed using synthetic microfiber media, this filter offers superior dust holding capacity, low pressure drop, and excellent filtration efficiency across a wide range of particle sizes. Its ideal for pre-filtration or final filtration in commercial, industrial, and institutional ventilation systems.

Key Features:

• Filter Media: Synthetic microfiber (non-woven, electrostatically charged for enhanced performance)

• Filtration Efficiency: MERV 8 to MERV 14 (or ISO ePM10ePM1 per ISO 16890)

• Construction: Pleated or bag-style options; galvanized steel or plastic frame

• Design: High dust-holding capacity and rigid structure to resist moisture and collapse

• Available Types: Panel filters, V-bank filters, bag filters

• Applications: Office buildings, shopping malls, hospitals, data centers, airports, cleanrooms, pharmaceutical and food processing industries

• Sizes: Standard and custom sizes available to fit most AHU designs

Frequently Asked Questions (FAQs)

1. What is a Microfiber AHU Filter?

A Microfiber AHU Filter is an air filter made with synthetic microfiber media, designed to trap fine dust, pollen, and other airborne particles in an AHU (Air Handling Unit). It enhances air quality and protects downstream HEPA or equipment components.

2. What is the advantage of microfiber media over traditional materials?

Microfiber media offers a larger surface area, better particle capture efficiency, and improved dust-holding capacity. It also resists moisture and microbial growth better than cellulose-based media.

3. What filtration ratings are available?

Microfiber AHU filters typically range from MERV 8 to MERV 14 (ASHRAE standard) or ISO ePM10 to ePM1 (ISO 16890). Higher efficiency options can approach HEPA-level performance in multi-stage filtration systems.

4. How often should I replace a microfiber AHU filter?

Replacement is recommended every 3 to 6 months, but this depends on environmental conditions, airflow, and the filters pressure drop. Some high-capacity versions may last longer.

5. Can microfiber filters be washed and reused?

No, microfiber filters are generally disposable. Washing can damage the fiber structure and reduce filtration efficiency. Always follow the manufacturer's recommendations.

6. Are these filters moisture-resistant?

Yes, synthetic microfiber filters are more resistant to humidity and microbial degradation compared to paper or cotton-based filters.

7. Can Microfiber AHU Filters be used as pre-filters for HEPA systems?

Yes, they are often used as pre-filters to extend the life of more expensive HEPA or ULPA filters in multi-stage HVAC systems.

8. What types of AHUs can use microfiber filters?

These filters can be used in most central HVAC systems, including rooftop units, ceiling-mounted AHUs, and industrial ventilation systems.
