Indications for Use

Porous Media oxygen concentrator filters are replacement filters intended for use in oxygen concentrator machines to help remove contaminants, including air borne bacteria and other particulate debris from an air stream. When used with oxygen concentrator machines, the replacement filters may be used in the home, nursing home, patient care facility, etc.

Device Story

Device consists of replacement filters (bacterial intake, compressor, and final bacteria filters) for oxygen concentrators; filters remove airborne bacteria and particulate debris from air stream. Air is drawn through intake filter, passes through compressor (with optional compressor filter), through sieve beds for nitrogen removal, and through final filter before patient delivery. Used in home, nursing home, or clinical settings; installed by users or technicians as maintenance components. Filters ensure air quality for oxygen generation; benefit includes reduction of contaminants in delivered oxygen.

Clinical Evidence

No clinical data. Substantial equivalence is based on bench testing comparing filtration efficiency, air flow resistance, and material specifications against predicate and OEM-equivalent filters.

Technological Characteristics

Filters utilize glass microfiber media for filtration. Housing materials include polystyrene, polyester, nylon 6/6, or polypropylene. Designed for specific oxygen concentrator models with varying connections (ISO male/female, hose barbs, NPT). Filtration efficiency ranges from 99.97% to 99.999% depending on filter type. Standalone mechanical components; no software or energy source.

Indications for Use

Indicated for use as replacement filters in oxygen concentrator machines to remove airborne bacteria and particulate debris from the air stream. Suitable for use in home, nursing home, and patient care facility settings.

The original component filters are approved for sale subject to the pre-market notifications outlined above. In each case the original filter is part of the 510(k) submitted for the oxygen. concentrator, such that, the original devices (oxygen concentrators) are indicated for use as oxygen generators and not filter devices. Because the original filters are not classified as separate devices, the Breathing Filter is included in this submission for the sole purpose of establishing the indications for use as a filter device.

JUN - 5 2006

{1}------------------------------------------------

Porous Media's devices identified in this submission are substantially equivalent to AG Industries Breathing Filter Bacterial/Viral (K052087), such that both are used as replacement filters in medical devices.

## Device Description

Room air is drawn into the compressor through the bacterial intake filter. From the compressor, the air passes through the compressor filter, if one is installed on the machine, and proceeds to the sieve beds. The sieve beds condition the air, by removing nitrogen from the air stream, which results in a higher concentration of oxygen. The air then passes through the final filter before being supplied to the patient.

### Intended Use

The devices identified in this submission are intended to help remove air-borne contaminants, including air borne bacteria and other particulate debris, from the air stream of an oxygen concentrator.

Dear Mr. Lehtonen:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
