Medium Efficiency Air Filter

1. Stable 1–5μm particle capture capacity, with efficiencies reaching F5–F9 / MERV 8–14

The filtration efficiency of a medium-efficiency filter primarily depends on its fiber structure, pleat depth, and material bulk density.

SYNRUI employs gradient density fibers and precise pleat control technology, resulting in a significantly higher 1–5μm particle capture capacity compared to ordinary models.

Precise control of fiber diameter and density reduces efficiency drift. Automatic pleating ensures uniform pleat spacing, preventing air bypass. Materials used include imported meltblown/synthetic fibers or high-grade glass fiber.

Maintains stable filtration efficiency over a long period, extending the HEPA pre-filter protection cycle.

2. High dust holding capacity design, extending service life by 20–35% compared to ordinary products. Medium-efficiency filters are commonly used in dusty environments; therefore, dust holding capacity determines the replacement cycle.

SYNRUI's advantages:

Deeply pleated Mini-Pleat structure (pleats ≥23mm)

Multi-bag structure (5–12 bags optional)

Progressive Density design

Under the same airflow conditions, SYNRUI medium-efficiency bag filters have a dust holding capacity approximately 20–35% higher than the market average.

3. Low initial resistance and low operating energy consumption (reducing HVAC equipment power requirements)

Resistance directly affects the energy consumption of air conditioning units.

SYNRUI optimizes materials, pleat depth, and frame structure to control initial resistance at:

Pleated: 55–95 Pa

Medium-efficiency bag: 70–120 Pa

V-type high airflow: 50–70 Pa

Compared to traditional medium-efficiency filters, this reduces resistance by approximately 10–18%, resulting in significant energy savings over long operating cycles.

4. Strict ISO/CE system guarantee, 100% product factory testing

We implement strict ISO9001 / ISO14001 / ISO45001 control measures. All medium-efficiency filters undergo the following checks before leaving the factory:

Efficiency inspection (EN779 / ISO 16890 standard)

Airflow and resistance testing

Leakage resistance and sealing inspection

Dimensional inspection

Welding strength inspection of metal frame and bag type

Ensuring consistent performance for each batch of products, without efficiency drift or unstable resistance.
