Custom Rectangular HEPA Air Filter with Diamond Metal Mesh & PU Gasket – Factory-Direct Solutions
A custom rectangular HEPA filter from our line is definitely worth a try, as it comes with a diamond-shaped metallic mesh top layer (protecting the HEPA material itself from damage), a close-fitting PU gasket (preventing any air from passing unchecked), and up to three different available frame material types (aluminum, galvanized steel, stainless steel). Constructed from high-quality melt blown material, this HEPA-enabled air filter is designed for effective air cleanliness in clean room environments, laboratories, electronics manufacturing facilities, and much more, as our factory manufactures this for exact customer specification.

| Galvanized Steel Frame | Rust-proof (hot-dip zinc coating), strong, cost-effective for heavy use. | General industrial environments (e.g., manufacturing plants, warehouses) with moderate dust/humidity. |
| Stainless Steel Frame (304/316) | Ultra-tough, 100% corrosion-resistant, handles chemicals and extreme temperatures. | Harsh conditions (e.g., pharmaceutical labs, chemical plants, coastal facilities) or sterile environments. |
Why This HEPA Filter Stands Out for Your Space
-
Diamond Metal Mesh Cover: Your Filter's Tough Protector
The diamond-pattern metal mesh solves two big problems:
Guards Against Damage: Prevents physical harm,such as scratches, tears, or debris impacts.
Uniform Airflow: Distributes air evenly across the filter surface, prevents reducing efficiency.
-
PU Gasket: Zero Leaks, Maximum Purification
Our integrated PU gasket ensures airtight performance:
Snug, Flexible Seal: The soft yet durable PU gasket molds to your equipment's intake,preventing unfiltered air bypassing the filter.
Long-Lasting Elasticity: Resists aging, cracking, or hardening even after years of use (works in -20℃~+80℃ temperatures).
Non-Toxic & Safe: Complies with standards-no harmful chemicals, making it suitable for food, pharmaceutical, or medical environments.
Fully Customizable – Built to Your Exact Needs
We don't do "one-size-fits-all"-your filter should fit your equipment, not the other way around. Here's how we customize it:
Dimensions: Any rectangular size (length × width × thickness) -share your equipment's filter slot measurements, and we'll match it perfectly.
Frame Material: Choose aluminum, galvanized steel, or stainless steel (304/316) based on your environment.
Filtration Efficiency: Adjust from H11 to H14 for your clean air requirements.
Metal Mesh: Thicker wire mesh for extra protection, or powder-coated mesh for corrosion resistance (custom request).
Gasket: Custom gasket thickness or material (EPDM for extreme temperatures) -just let us know.
Branding: Add your logo or part number (MOQ: 200 units) for OEM/ODM orders.

Frequently Asked Questions (FAQ)
Q1：What are the benefits of diamond pattern mesh?
A: The diamond-shaped pattern is the strongest and has the least restriction of airflow, offering a level of protection that squares cannot.
Q2: What are the reasons for selecting a gasket of PU material over?
A: The PU gaskets are elastic and resist aging, and the sealing performance remains intact even in changing temperatures.
Q3: What's the typical lifespan of these filters?
A: Under normal conditions, 6-12 months. Actual lifespan depends on air quality and usage hours.
