Pad Filter

Product Description

Pad Filters are economical, disposable air filters designed primarily for coarse particulate filtration in HVAC systems. Typically made from synthetic fibers or glass wool, pad filters are available in rolls, cut pads, or metal-framed panels. They are often used as pre-filters to extend the service life of higher-efficiency filters such as mini pleat or HEPA filters.

Pad filters are especially valued for their low initial resistance, ease of replacement, and customizable sizing, making them ideal for spray booths, air handling units (AHUs), pre-filter stages, and ventilation systems in commercial, industrial, or residential applications.

“ FAQs “ Mini Pleat Filters (in relation to Pad Filters)

1. What is the difference between pad filters and mini pleat filters?

• Pad filters capture larger particles (e.g., dust, fibers, pollen) and are used in pre-filtration stages.

• Mini pleat filters capture fine particles (e.g., smoke, bacteria, PM2.5) and are used in secondary or final filtration.

2. Can pad filters be used alone?

Yes, in non-critical applications such as basic HVAC systems or paint booths. However, for cleaner air or sensitive environments, pad filters should be paired with higher-efficiency filters like mini pleats or HEPA.

3. How often should pad filters be replaced?

Every 1“4 weeks, depending on the environment and dust load. Pad filters are disposable and not intended for washing or reuse.

4. Do pad filters help extend the life of mini pleat filters?

Absolutely. By capturing large debris and dust first, pad filters protect the finer media of mini pleat filters, reducing clogging and extending service intervals.

5. Are there pad filters with higher MERV ratings?

Generally, pad filters are limited to MERV 2“8. For finer filtration with compact design, mini pleat filters (MERV 13“16 or HEPA) are more appropriate.

6. Can I retrofit an existing system to include both pad and mini pleat filters?

Yes. Many air handling units and fan filter systems allow the integration of multi-stage filtration, where pad filters are used as pre-filters, followed by mini pleat or HEPA filters.

7. Are pad filters suitable for cleanrooms?

No. Pad filters alone are not sufficient for cleanroom standards. They may be used as initial filters in multi-stage systems but should always be followed by high-efficiency filters such as mini pleats, HEPA, or ULPA.
