Cost savings and convenience with reusable sterilizer filters
Our POREX® Virtek™ reusable filters function in two ways: as a vent to allow pressure equalization during the sterilization process, and as a filter barrier to bacteria during subsequent storage. These reusable filters, comprised of sintered polytetrafluoroethylene (PTFE), are engineered and designed to withstand repeated sterilization cycles as well as deliver substantial performance, convenience, and cost savings over traditional single-use paper and textile filter materials.
Free of animal-derived additives and considered UPS Class VI, these reusable filters:

Protect healthcare workers from pathogen exposure when using IV catheters.
POREX® safety IV catheter vents are self-sealing vent components assembled into a safety IV catheter device. This medical device is inserted into a patient’s vein to serve several important functions: to obtain blood samples from patients, to introduce fluids such as sterile saline, or to administer drugs such as IV antibiotics.
The self-sealing POREX safety IV catheter vents immediately shut off upon contact with fluids – including blood – thereby eliminating blood bypass in the “flashback chamber” to protect healthcare employees from exposure to blood and bloodborne pathogens.
Compatible with gamma, e-beam, and ethylene oxide (EtO) sterilization processes, our safety IV catheter vents:
| POREX® Virtek™ IV Catheter Media | ||||

Protect central vacuum system lines from contaminants in collection canisters
Hospital central vacuum systems support many devices used in surgical procedures. Designed to be self-sealing, our POREX® suction canister filters help maintain the integrity of these systems. POREX® suction canister filters effectively filter the air and protect the vacuum system lines from contaminants in the fluid contained within the collection canister.
Comprised of porous plastic containing a functional additive, our suction canister filters behave as a valve by automatically and instantly shutting off airflow from the collection canister when collected fluids come in contact with the filter.
With its single-body design that meets original equipment manufacturer (OEM) needs for high-volume, single press-fit assembly, POREX suction canister filters:
| BFE Results (modified ASTM F2101) | |||
| Product | Description | BFE | Airflow SCFH |
|---|---|---|---|
| PPV1 | Standard BFE | 99.98% | 29.2 |
| PPV2 | High BFE | 99.996% | 27.6 |
| PPV3 | Super BFE | 99.999994% | 15 |

Prevent operating room infections by absorbing infectious fumes
POREX® porous fume absorbers are used for the convenient and efficient eradication of noxious fumes generated in the cement-bone mixing process during surgical procedures in hospital operating rooms.
Designed with porous plastic disks that surround activated carbon material, POREX porous fume absorbers create a porous fume filter that supports balanced air flow rates, optimal back flow pressure, and out-gas residence times.
Accommodating device fit requirements with its specified part geometry, our porous fume absorbers:
