I. Product Introduction
The Pre Filter G3/G4 is a high-efficiency air pre-filter designed to capture large particulate matter (dust, pollen, fibers, etc.) in ventilation and air purification systems. It serves as the first line of defense, extending the lifespan of downstream HEPA or activated carbon filters.
II. Product Features
1. High Dust Holding Capacity: Reduces frequent replacements.
2. Low Air Resistance: Maintains system airflow efficiency.
3. Eco-Friendly Options: Reusable/washable variants available.
4. Durable Frame: Rigid (aluminum/plastic) or flexible (pleated) designs.
5. Fire-Resistant: Complies with industry safety standards (e.g., EN 60335).

IV. Product Applications
- HVAC System: Pre-filter for commercial buildings/hospitals.
- Industrial: Paint booths, manufacturing clean air intake.
- Residential: Air purifiers, kitchen hoods.
- Pharmaceutical/Labs: Particle control in sterile environments.
V. FAQ
Q1: How often should I replace the G3/G4 filter?
- Answer: Typically every 3–6 months (depends on air quality and usage). Washable models can be cleaned monthly.
Q2: Can G4 replace a G3 filter?
- Answer: Yes, but check system compatibility (higher resistance may affect airflow).
Q3: Is the filter recyclable?
- Answer: Synthetic fiber filters are disposable; aluminum mesh frames can be recycled.
