Intended Use

The Pall-Aquasafe Water Filter is intended to be used to filter EPA (Environmental Protection Agency in USA) quality drinking water. By retaining bacteria, the filters may aid in infection control. The filters produce water that is suitable for washing and drinking, superficial wound cleansing (minor cuts, scrapes, or abrasions), cleaning of equipment used in medical procedures and washing of surgeon's hands. The filters are not intended to provide water that can be used as a substitute for USP grade sterile water.

Device Story

Pall-Aquasafe Water Filter is an in-line, sterile, 0.2-micron Supor (polyethersulfone) membrane filter cartridge; designed for healthcare environments to reduce waterborne microorganisms (bacteria, protozoa, fungi) via size exclusion. Device connects to in-line plumbing; operates for up to 31 days. Healthcare providers use filtered water for washing, drinking, superficial wound cleansing, and cleaning medical equipment. Bacteriostatic additive in PBT housing reduces external microbial contamination. Benefits include infection control for immune-compromised patients exposed to waterborne pathogens. Device is not a substitute for USP sterile water.

Clinical Evidence

Bench testing only. Microbial retention validated per ASTM F838-05 and HIMA guidance using Brevundimonas diminuta (≥ 1x10^7 CFU/cm2). Fungi retention tested with Aspergillus fumigatus. Biocompatibility testing performed per ISO 10993 (L929 MEM Elution, Kligman Guinea Pig Maximization, Intracutaneous Injection, Systemic Injection, Rabbit Pyrogen). Mechanical integrity confirmed via burst pressure, shelf-life, and flow rate testing.

Technological Characteristics

0.2 µm Supor (polyethersulfone) membrane with integral pre-filter; PBT (polybutylene terephthalate) housing with bacteriostatic additive. In-line plumbing connection. Max pressure 75 psi at 140°F. Sterilized. Size exclusion principle. No software/electronics.

Indications for Use

Indicated for use in healthcare environments (hospitals, nursing homes, clinical settings) to filter EPA-quality drinking water for immune-compromised patients, washing, drinking, superficial wound cleansing, and cleaning medical equipment/surgeon's hands.

## Non-clinical Tests Include

Microbial Retention Verification – Testing designed using ASTM F838-05 and Health Industry Manufacturers Association (HIMA) Guidance for validating 0.2 micron sterilizing grade filters using Brevundimonas diminuta at a challenge level of ≥ 1 x 10' colony forming units (CFU) per cm of effective filtration area. All analysis membranes were found to be free of the test organism.

Microbial Retention in Intermittent Use – Testing designed to confirm that the Pall-Aquasafe Water Filters retain the microbial challenge organism Brevundimonas diminuta during typical intermittent use for a period of 35 days using ASTM F838-05 and Health Industry Manufacturers

{6}------------------------------------------------

Association (HIMA) Guidance for validating 0.2 micron sterilizing grade membranes. All analysis membranes were found to be free of the test organism.

Retention of Fungi – Testing performed to demonstrate that the Pall-Aquasafe Water Filters are capable of retaining fungi during a period of one calendar month (maximum 31 days) using Aspergillus fumigatus delivered (Day 1: 1 x10° CFU; Day 15: 2 x 10+ CFU and Day 36: 2.4 x 10° CFU). Plates were incubated for 10 days and then integrity tested. Less than 1 (CFU/500mL) were recovered downstream of the filter.

Maximum Operating Temperature and Pressure Rating - Pall-Aquasafe Water filters were tested for operating at a continuous maximum temperature of 60 ℃ combined with a maximum inlet pressure of 5 bar. The filters were also tested to withstand 70 ℃ for a cumulative period of 30 minutes over the life of the filter. Filters were integrity tested and testing demonstrated that the filters maintain their integrity over their simulated service life.

## Flow Rate Testing at water pressures of 15, 25, 45, 60 and 75 psi

Shelf Life Testing The following testing was performed: Integrity Testing of the Packaging Bacterial Challenge Burst Pressure Testing Three-year real-time Shelf Life Testing Five-year accelerated aging Shelf Life Testing All filter capsules tested retained integrity and maintained a safety margin above maximum operating pressure after three and five year real-time storage and five years accelerated aging.

### Evaluation of Bacteriostatic Additive

Testing demonstrated that the bacteriostatic additive incorporated within the housing polymer to reduce external microbial contamination by greater than 99.5% after 24 hours contact.

### Biocompatibility Testing

Biocompatibility evaluation for the Briostor Transfer/Freezing Bag Set was conducted in accordance with the FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO-10993, Biological Evaluation of Medical Devices Part 1: Evaluation and Testing: May 1, 1995, and the International Standard ISO 10993-1 "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing Within a Risk Management Process" as recognized by FDA.

The Pall-Aquasafe Water Filters are categorized as an "External Communicating Device, Breached/compromised surfaces, Contact Duration: Limited Exposure.
