A portable HEPA device will not create a negative pressure room unless it can be directly discharged to the outside. The HEPA filter is a fixed filter in the air conditioning system, and there are also HEPA filtering machines that simply circulate the air inside the room after cleaning. This type of filter is capable of filtering microorganisms, including most viruses, and it also cleans all dust from the air. Negative pressure will be maintained if HEPA-filtered air is vented to an adjacent area within the building.
The HEPA-AIRE PAS can also be used for continuous air cleaning, by recirculating 100% of the filtered air within the containment area. This will increase the ACH in the project area and provide HEPA filtration, but it will not generate negative pressure. The XJ-2 medical HEPA filter is suitable for airborne infection isolation (AIIR) rooms, hospitals, dental offices, nursing homes, immediate care facilities, doctors' offices, facilities, and institutional use. This air cleaning system is very quiet and is specifically designed for use in airborne infection isolation (AIIR) rooms, hospital isolation rooms, medical environments, and hospital infection control applications.
Negative pressure rooms and HEPA negative air machines are used to protect people who live in health centers and hospitals but are not affected by COVID-19. A modular containment system or polyethylene barrier can be used to connect a portable air purifier or a HEPA negative air machine. All models are equipped with easy to read and use filter change indicator lamps that light up when filters need to be replaced. When positive pressure is used, the air filter maintains a higher ambient air pressure than that of the surrounding environment, which means that particles are filtered when air leaves the room and are prevented from returning. Portable air cleaners with a HEPA filter are designed to capture a wide range of particles, including a HEPA filter tested and certified to remove 99.97% of particles of 0.3 microns or larger, to provide clean filtered air in the operating room.
It is essential to use a HEPA filter in a negative air machine because of its particle-forming ability. The unit creates a negative vacuum that causes air to enter and pass through a filter (such as HEPA or ULPA) and connected ducts to remove impurities, such as microbes, dust, and mold. As the filters are loaded with particulate matter, the air flow capacity of the unit decreases and the static pressure difference in the filter increases. OSHA requirements for negative air rooms should refer to HEPA-type negative air machines as well as general knowledge about dust suppression machines.
In order to ensure safety in health centers and hospitals, it is important to understand how these machines work and how they can help protect people from airborne diseases like COVID-19. A HEPA filter is an effective way to capture particles from the air and prevent them from entering a room or building. It is important to note that while these filters can help reduce airborne particles, they cannot create a negative pressure room on their own.
