Material & Construction of HVAC Return Air Filter
This Primary Air Filter adopts a single or two-layer construction depending on requirements. The filter medium is high-density non-woven fabric with excellent dust holding capacity and air permeability. The supporting frame is available in galvanized steel wire or lightweight aluminum, both with corrosion resistance and rigid structure.
Advanced edge sealing eliminates air leakage between the frame and filter medium. The rigid frame prevents deformation during installation and operation. Strict quality control ensures uniform material thickness and stable frame connection, complying with industrial filtration standards.

FAQ on Primary Air Filter with Steel Wire/Aluminum Frame
Q: What is the filtration efficiency?
A: G4 grade performance, capturing 90–95% of particles larger than 10 μm, including dust, lint and pollen for basic air filtration.
Q: Can custom sizes be ordered?
A: Yes, fully customizable dimensions for all HVAC system configurations.
Q: Which frame type is better?
A: Steel wire frames is economical option; while aluminum frames in-built steel wire are more rigid, not easy to deform. Both are suitable for standard HVAC applications. The thickness of Steel wire frames is only 4mm, so, if your duct slot is small, we suggest to use steel wire frame.
Q: How often should the filter be replaced?
A: Standard replacement every 3–6 months; high-dust environments require replacement every 1–2 months.
Q: Suitable for residential air conditioners?
A: Fully compatible with residential, commercial and HVAC return systems with matched sizes.
Q: Does it resist moisture?
A: Moisture-resistant non-woven material prevents mold and maintains stable performance in humid conditions.
Q: Is installation simple?
A: Easy insertion into return air vents or duct slots; no special tools required.
Q: Does it reduce energy consumption?
A: Low air resistance reduces airflow resistance and improves overall HVAC energy efficiency.
