Cardboard Frame Primary Air Filter Economical Pre-Filtration – Easy In, Easy Out
Overview
A cost-effective, disposable pre-filter designed for quick, tool-free replacement. Protects your expensive downstream filters and HVAC equipment – change it regularly and save on maintenance costs.
Key Features
- Economical Consumable: Priced for frequent replacement. Extends the life of higher-grade filters, reducing overall operating costs.
- Easy to Install & Replace: Standard 595×595×46mm size fits most common filter racks. No tools needed – change out in minutes.
- Reliable Filtration: Pleated primary filter cotton captures particles ≥5μm (G3/G4 efficiency). High dust-holding capacity with low airflow resistance.
- Durable Support: Single-sided metal diamond-mesh guard keeps pleats stable and prevents media collapse under airflow.
- Lightweight Paper Frame: Sturdy yet fully disposable.
Applications
HVAC systems, air handling units, spray booths, cleanroom pre-filtration, and general industrial ventilation.

Green & White Filter Media Cotton Aluminum Alloy Frame Filters G3 G4 Pre Filtration Pleated Panel Air Filters
Description:
Our Green & White Pre-Filter Media is a high-performance, dual-layer synthetic fiber filtration material engineered for primary air filtration. Featuring a distinct color gradient—White on the air intake side and Green on the exhaust side—this media utilizes a progressive density structure. The open white layer captures larger particulates, while the denser green layer traps finer dust, ensuring optimal depth loading.Manufactured from high-quality PET (Polyester) and PP (Polypropylene) fibers, this filter media offers excellent dust-holding capacity with low initial resistance. It is rated at G3 or G4 efficiency (EN 779) , effectively removing airborne contaminants ≥5μm. It delivers reliable, cost-effective performance for a wide range of commercial and industrial applications.
Key Features:
- Dual-layer green/white design for easy identification of airflow direction.
- Progressive fiber structure for high dust loading and extended service life.
Applications:
- HVAC systems and central air conditioning intake pre-filtration.
- Spray painting booths and coating workshops (as ceiling or floor mats).
- Cleanroom ante-rooms and equipment air intake protection.
- General industrial dust collection systems.

Nylon Mesh Pre-Filter
The Nylon Mesh Pre-Filter is a durable, washable air filter designed for coarse particle filtration in HVAC systems, industrial equipment, and air handling units. Made from high-strength nylon monofilament mesh, it serves as the first line of defense to protect downstream filters (e.g., HEPA, carbon) from large debris.

Galvanized Frame Panel Filter
The Galvanized Frame Panel Filter features a unique dual-frame structure (fixed outer frame + removable inner frame), specifically developed for high-airflow, easy-maintenance ventilation systems. As the first line of defense in air handling systems, it effectively captures particles ≥5μm (dust, fibers, etc.) to protect downstream medium/high-efficiency filters and equipment.
