General pre-filter media for air conditioning and industrial use. The main choice is thickness.
Thin media (5–10 mm) suits general air-conditioning vents and electronic equipment vents; thick media (15–30 mm) has higher efficiency and dust-holding capacity, for cleanroom air-conditioning pre-filters and dusty industrial areas. Fixed size 50 × 50 cm, cut freely to fit your equipment openings.
Quick specifications
| Item | Specification |

Choosing thickness
| Thickness | Dust capacity | Where used | Note |
|---|---|---|---|
| 5 mm | Low | Electronic equipment vents, small AC outlets, pick-and-place pre-filters | Thin, for tight spaces |
| 10 mm | Medium | General factory AC filtration, enclosure front panels | General purpose, common size |
| 15 mm | Medium-high | Air compressor intakes, equipment exhaust ports | Moderate dust |
| 20 mm | High | Cleanroom pre-filters, paint booth pre-filter stage | Longer life, longer service intervals |
| 30 mm | Higher | Heavy industry with high dust, pharmaceutical pre-filtration | Highest dust capacity, fewer changes |
Material
- Dense, even fibers: capture airborne particles and reduce shedding.
- Low resistance: keeps good airflow without loading the fan.
- Easy to cut: the 50 × 50 cm sheet can be cut to any opening; no custom order needed.
- Reusable: can be reused after suitable cleaning, lowering consumable cost.
Where it is used
| Environment | Thickness | Note |
|---|---|---|
| Electronics / SMT line air conditioning | 10–15 mm | Keeps dust out of precision assembly areas |
| Food processing | 15–20 mm | Reduces airborne particles at the line |
| Pharmaceutical pre-filtration | 20–30 mm | Pre-filter ahead of HEPA, extends HEPA life |
| Paint booths (pre-filter stage) | 20–30 mm | Catches larger overspray particles, protects later stages |
| Offices / AC units | 5–10 mm | Reduces dust indoors |
