Box HEPA Filter

Box HEPA Filters are mainly used in clean rooms and clean areas where pollutants are strictly controlled. The filter media used is water-resistant and flame-retardant fiberglass.
The filter material is separated by aluminum partitions. The corrugated aluminum partitions can accurately give place to the filter media, which is used as much as possible to reduce resistance. The edges of the partitions are specially treated to prevent damage to the filter material.
Polyurethane glue seals the filter media and the frame to prevent air leakage. The sealant completely seals the edges of the filter element and the partitions, sealing all possible leakage channels.
Frame material: galvanized iron, stainless steel, etc.
Filter material: multi-purpose glass fiber filter media H13/H14, other grades can be chosen by customers.

Box HEPA Filter Industry knowledge

What are the advantages of using fiberglass for Box HEPA filters?

Box HEPA filters typically use fiberglass media as it has several benefits that make it ideal for high-efficiency air filtration. Here are some advantages of using fiberglass media:

1. Efficient: Glass fiber media is very efficient and can remove sub-micron sized particles with an efficiency of up to 99.97%.

2. Durability: Fiberglass media is extremely durable and maintains its shape and structure even under high flow rates and high pressure drops.

3. Hydrophobic and Oleophobic: Fiberglass media is generally hydrophobic and oleophobic, helping to repel water and oil molecules and prevent moisture and oil from accumulating on the filter.

4. Chemical Resistance: Fiberglass media is generally resistant to a wide range of chemicals, helping to prevent damage from chemical vapors and gases.

5. Antimicrobial: Fiberglass media is generally resistant to the growth of bacteria and mold, helping to prevent biological contamination on the filter.

6. Low resistance: Fiberglass media generally has low resistance, helping to reduce the energy required for air to pass through the filter.

7. Low Maintenance: Fiberglass media typically requires very little maintenance, helping to reduce filter operating costs.

8. Cost-Effectiveness: Fiberglass media is generally cost-effective compared to other media, helping to reduce the overall cost of the filter.

9. Versatility: Fiberglass media can be used in a variety of applications, including commercial and industrial HVAC systems, clean rooms, and medical facilities.

10. Customizability: Fiberglass media can be customized to meet the requirements of specific applications, such as different densities, thicknesses, and arrangements.

11. Sustainability: Fiberglass media is a recyclable and reusable material that helps reduce waste and promote sustainability.

12. Maintenance: Maintenance of the Box HEPA filter, such as regular cleaning and replacement, helps maintain the performance of its fiberglass media, thereby extending its lifespan.

Why are Box HEPA filters waterproof and flame retardant?

Box HEPA filters are designed to be waterproof and flame retardant, helping to improve their performance and safety. Here are some reasons why Box HEPA filters are waterproof and flame retardant:

1. Prevents water damage: Water-resistant properties help prevent filter damage in high humidity environments or accidental exposure to water. This helps maintain the performance of the Box HEPA filter and extend its life.

2. Prevents Bacteria and Mold Growth: The water-resistant properties help prevent moisture buildup on the Box HEPA filter, which can promote the growth of bacteria and mold, which can affect the filter's performance and cause bad odors.

3. Improved Efficiency: The water-resistant properties help increase the efficiency of the Box HEPA filter as it helps prevent moisture from building up on the filter, which could reduce its performance.

4. Reduced Maintenance: The water-resistant properties help reduce maintenance on the Box HEPA filter as it helps prevent moisture buildup on the filter, which may require more frequent cleaning and replacement.

5. Improved safety: Flame retardant properties help prevent the filter from becoming a source of fire spread in the event of a fire. This helps improve the safety of facilities using filters.

6. Comply with regulations: Waterproof and flame retardant properties may help Box HEPA filters comply with regulations and standards for certain industries or applications.

7. Durability: The waterproof and flame retardant properties help make the Box HEPA filter more durable as it helps resist physical damage and environmental factors, which may affect its performance.

8. Versatility: Water-resistant and flame-retardant properties make Box HEPA filters suitable for a variety of applications, including high-humidity environments, clean rooms, and medical facilities.

9. Maintenance: Maintenance of the Box HEPA filter, such as regular cleaning and replacement, helps maintain its waterproof and flame retardant properties, thereby extending its lifespan and improving its performance.

10. Protection: Waterproof and flame retardant properties help protect the Box HEPA filter from accidental damage, which may affect its performance and shorten its lifespan.
