A HEPA (High Efficiency Particulate Air) filter is a highly efficient air filter designed to capture 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, bacteria, and other contaminants.

The 0.3 micron particle size is considered the Most Penetrating Particle Size (MPPS) — the hardest size to capture. A HEPA filter that can trap particles of this size ensures excellent filtration performance for all larger and smaller particles.

HEPA filters are used in cleanrooms, hospitals, laboratories, pharmaceuticals, electronics manufacturing, food processing, and even residential air purifiers to maintain contaminant-free environments.

Unlike standard filters, HEPA filters are designed to meet strict efficiency standards (99.97% at 0.3 microns) and provide superior particle filtration for sensitive and controlled environments.

Yes. Blue Sky System Pvt. Ltd. manufactures HEPA filters in various sizes, shapes, and specifications to meet unique client requirements and industry standards.

The replacement cycle depends on usage, environment, and application, but typically HEPA filters should be replaced every 6–12 months or as per performance test results.

While HEPA filters are not specifically rated for viruses, they can capture many virus-carrying particles attached to droplets or aerosols due to their high filtration efficiency.
