HEPA-VENT in-line disk filters are convenient, disposable, light-weight filters with high-efficiency glass fiber media for maximum particle retention.

• Randomly arranged glass microfiber media is strengthened by dual lamination with a tough polyester monofilament for increased capacity
• Meets high-efficiency particulate arrestance standard, retaining 99.97% of all particles ≥0.3 µm in air
• Depth design results in extremely high retention and bidirectional flow rate

HEPA air filter products offer particle retention of even heavily particulate-laden air samples. Whatman HEPA-VENT filters are highly suited for applications where high retention, dirt-holding capacity, and flow rates are required. They are typically used as in-line filters during air or gas filtration in fermenters, or incubators.
