Mechanical Filter FAQ
Q: How often should I replace my mechanical filter?
A: Replacement frequency depends on the application and contaminant load. For standard HVAC systems, inspect every 3 months and replace every 6-12 months. In industrial applications with heavy particulate loading, monthly replacement may be necessary. Our filters include pressure drop indicators to help determine optimal replacement timing.
Q: What's the difference between a mechanical filter and an electronic air cleaner?
A: Mechanical filters physically capture particles on filter media through impaction, interception, and diffusion. Electronic air cleaners use electrostatic charges to attract particles. Mechanical filters typically have lower maintenance requirements and don't produce ozone, while electronic cleaners can handle smaller particles but require more frequent cleaning.
Q: Can mechanical filters remove gases and odors?
A: Standard mechanical filters primarily capture particulate matter. For gas phase filtration, you would need an activated carbon layer added to the mechanical filter. We offer hybrid filters combining mechanical filtration with activated carbon for applications requiring both particulate and odor control.

Mechanical Filter Installation Guidelines
- Always follow airflow direction arrows marked on the filter frame
- Ensure proper sealing around edges to prevent bypass
- For bank installations, maintain minimum 12" spacing between filters
- Record initial pressure drop as baseline for future maintenance
- Wear appropriate PPE when handling used filters
Mechanical Filter Maintenance Procedures
| Task | Frequency | Procedure |
|---|---|---|
| Visual Inspection | Monthly | Check for visible dust loading, frame damage, or media tears |
| Pressure Drop Measurement | Bi-monthly | Compare current ΔP to initial reading; replace if increase exceeds 50% |
| Full System Check | Annually | Inspect housing, gaskets, and verify proper airflow |
