Engineering Performance & Features of Open Cell Filter Foam
Controlled 10 PPI to 60 PPI Porosity for Targeted Dust Capture: Utilizes uniform 10 PPI to 60 PPI Filter Foam pore structures to effectively intercept dust, fibers, and airborne particulates ≥15μm, preventing downstream medium and HEPA filter overloading.
High Air Permeability & Low System Resistance: Features a 97% open-cell porosity matrix that eliminates blind pores, keeping initial resistance ≤90 Pa. This High Air Permeability Filter Foam maintains steady airflow while lowering fan energy consumption.
Oil, Solvent & Chemical Endurance: Engineered with premium polyester and polyether resins, providing excellent resistance to machine oil mists, organic solvents, and mild acids or alkalis (pH 5.0 – 8.0).
Washable & Reusable Structural Integrity: Boasts a tensile strength of 45 kPa and an elongation rate of 65%. The media tolerates repeated water washing, compressed air blowing, and chemical cleaning without structural collapse or mesh deformation.
Functional Modification Flexibility: The 3D skeletal structure serves as an optimal substrate for functional secondary coatings, including activated carbon impregnation, photocatalysts, or metallic and ceramic matrix processing.
Material Specifications & Non-Standard Customization Services
We provide full-scope OEM/ODM manufacturing, transitioning raw polyester and polyether formulations into high-performance Polyurethane Filter Foam Roll and sheet products tailored to exact engineering drawings.
Custom Pore Sizes (PPI Range): Precision manufacturing from 10 PPI (coarse, high-dust-capacity media) to 60 PPI (fine, high-efficiency media).
Flexible Supply Formats: Available in standard 1m × 2m sheets, continuous rolls, or custom-cut pads ranging from 3mm to 50mm in thickness.
Precision CNC Die-Cutting: Advanced Die Cut Air Filter Sponge processing with tight tolerances (≤1mm), ensuring burr-free edges, clean dimensional fitting, and zero material shedding during installation.
Functional Additives: Optional anti-static modification (2.0*) and UL94 compliant flame-retardant additive treatments for stringent industrial safety compliance.
HVAC & Fresh Air Intake Systems: Serves as HVAC Air Pre Filter Foam in central air conditioners, fan coil units, and air handling units to intercept coarse dust and insects.
Paint Spray Booths & Finishing Lines: Applied as Spray Booth Air Filter Foam in automotive and industrial paint booths for airflow diffusion and pre-capturing paint mist particles.
Machinery Oil Mist Separation: Functions as Industrial Machinery Oil Mist Filter Foam in CNC machining centers, cold heading machines, and exhaust duct mist separators.
Electronics Enclosures & Server Racks: Serves as Server Cabinet Air Dust Filter Sponge in telecom cabinets, power distribution boxes, and IT hardware enclosures for dust protection and thermal management.
Exhaust Gas & Substrate Applications: Used as the base carrier for activated carbon odor-control filters and pre-filtration media in VOC abatement systems.

Q1. What PPI rating should I select for my specific industrial application?
A1: Pore size selection depends on your airflow and filtration efficiency requirements. Coarse ratings (10 PPI to 20 PPI) offer minimal airflow resistance and high dust holding capacity, ideal for high-velocity HVAC pre-filtration and heavy dust environments. Medium to fine ratings (30 PPI to 60 PPI) provide higher capture efficiency for finer dust and oil mists, making them ideal for spray booths, electronics enclosures, and secondary stage pre-filtration.
Q2. Can your Air Filter Sponge media be cleaned and reused, and what is the expected service life?
A2: Yes, our foam media is constructed from durable polyester/polyether reticulated polymer structures with an elongation rate of 65% and high tensile strength. It can be repeatedly washed with clean water, blown with compressed air, or cleaned with mild detergent solutions. Under normal industrial operating conditions, the media maintains a service life of 3 to 5 years without structural deformation.
Q3: 3. Do you offer custom die-cut shapes based on OEM equipment dimensions?
A3: Absolutely. As a dedicated source manufacturer, we offer full CNC die-cutting services for a custom Die Cut Air Filter Sponge. You can provide CAD drawings or physical dimensions, and we produce customized pads, gaskets, or contoured filters with precision tolerances held within ≤1mm, guaranteeing a tight fit in your equipment housings.
Q4. Is your UL94 Flame Retardant Filter Foam certified for international market export?
A4: Yes. We offer specialized flame-retardant modifications that comply with UL94 vertical and horizontal flammability testing specifications. Additionally, our foam materials comply with European RoHS and REACH environmental regulations, ensuring full compliance for project bidding and customs clearance in North America, Europe, and Asia-Pacific markets.
Q5. What is the minimum order quantity (MOQ) and lead time for Custom Size Filter Sponge Wholesale orders?
A5: We support B2B procurement with flexible volume tiers for both standard 1m × 2m sheets and custom continuous rolls. Standard trial orders can be dispatched quickly, while custom die-cut or specialty modified volume orders are typically processed within 10 to 15 business days depending on volume and specification requirements.
