DALON’s 5µm porous sheet filter is a compact, cuttable sintered polyethylene (PE) filter sheet designed for precise particle removal in sensitive air or fluid applications. With uniform pore distribution and fine 5-micron nominal filtration, this 260 mm × 260 mm × 4 mm PE sheet offers efficient protection against micro-contaminants such as dust, aerosols, or suspended solids—without restricting airflow.
Lightweight and chemically resistant, this filter sheet is ideal for use in sensor assemblies, battery compartments, medical analyzers, and electronics enclosures. It can be die-cut or CNC-trimmed into custom shapes for seamless OEM integration.

DALON is an ISO 9001:2015-certified manufacturer specializing in precision sintered plastic filter materials for global OEMs. Our porous sheet filters are produced under controlled sintering conditions to ensure reliable porosity, mechanical strength, and dimensional tolerance.
We offer custom pore grades (5–100µm), sheet dimensions, and surface treatments (hydrophilic/hydrophobic), as well as technical support for die-cutting and bonding. DALON partners with manufacturers across environmental sensing, healthcare, mobility, and electronics sectors for both prototyping and volume production needs.
Q1: What does a 5µm porous sheet filter remove?
It blocks very fine airborne dust, particulates, and vapor-borne debris from entering enclosures or devices, ensuring internal component cleanliness.
Q2: Can this sheet be cut to custom sizes?
Yes. The PE sheet is compatible with die-cutting, CNC trimming, or scissors for basic shapes.
Q3: Is it safe for use in electronic or battery-powered equipment?
Absolutely. The material is non-conductive, stable, and safe for proximity to circuitry and lithium-based energy systems.
Q4: Can it be used in wet or humid environments?
Yes. Sintered PE is hydrophobic by default and does not swell or degrade under normal humidity or splash water exposure.
Q5: What makes this filter suitable for OEM use?
Its stable porosity, light weight, and ease of integration into sealed housings or custom panels make it ideal for OEM design flexibility.
Q6: What industries use this filter type?
Common in environmental electronics, medical analyzers, automotive battery systems, lab ventilation, and enclosure panel filters.
