Hospital Air Purification Systems

The efficiency of hospital air purification systems is dependent on a variety of elements. One of the most crucial aspects is their capability to eliminate airborne pollutants. This article examines COVID-19 filtering, HEPA filters, and carbon-activated filters. The article will also cover RxAir. Selecting the best medical air purification equipment is essential to ensure the safety of staff and patients. Here are the most important features to look for when it comes to hospital air purification systems.


Air purification systems for hospitals that include COVID-19 protection are an important element of the health facility’s infection control program. Apart from protecting the health workers and patients, AII rooms are also vital to prevent the spread of diseases that are infectious. They are in high demand until there is a vaccine created for COVID-19. The air purification devices can be beneficial when it comes to intubating patients suffering from COVID-19 or getting them off ventilators or performing procedures that generate aerosols.

The COVID-19 task team, established through the World Health Organization and the U.S. Federal Government, identified five critical care units (ICUs) and various other areas where filtration of hospital air is vital. ASHRAE offers five methods of distribution of air to the patient’s room. In each of these areas, the COVID-19 air purification system for hospitals should be in line with ASHRAE’s guidelines.

HEPA filters

The utilization of HEPA filters in air purification systems could increase the efficiency of ACH as well as reduce the number of particles that circulate and enhance patient safety. The portable HEPA filters are made to eliminate particles that could transmit infections in general. If there is an outbreak of COVID-19, HEPA filtration will help reduce the risk of transmission. Furthermore, HEPA filters are effective in capturing particles of the SARS-CoV-2 virus.

In contrast to traditional filtering methods, HEPA filtering doesn’t employ sieves or strainers. They make use of pleated sheets of fiberglass fibers having dimensions ranging from 0.5 to 2 micrometers. The motorized fan of the filter pushes to push air across the pleated surface. Particles that are 0.3 microns or greater are captured through impaction which is the method by which big particles are stuck on the fabric. Interception, the third method comprises particles smaller than 0.5 microns in size. The particles may move through certain fibers but stick to just one.

Carbon activated filters

Air filters made of activated carbon are efficient in getting rid of harmful air pollutants. The carbon activated works by adsorbing substances into the structure of the material which is different from absorption in which the substance becomes a component of the material at the molecular scale. The sponge absorbs water, however, it doesn’t chemically bond with it, however, it fills the space. Air filtration systems for hospitals remove harmful substances like VOCs and gases that could negatively impact the health of the workers.

Activated carbon is activated by carbon dioxide, hot air, or steam. This can be believed to render carbon more porous, and also increase its ability to absorb. It is screened and compressed in order to meet certain specifications. Carbon that is activated for air purification systems will be more effective when it has a higher amount of carbon pure. But, it’s important to keep in mind that carbon filters aren’t totally impregnated with chemicals, and they should be compatible with the air quality in the room where they will be.


RxAir hospitals’ air purification systems have been confirmed to decrease exposure to harmful viruses, harmful bacteria, and smells. Its cutting-edge technology is relied upon by more than 400 hospitals across the world. Its RxAir device is much more efficient in reducing indoor pollution such as odors, odors, and VOC concentrations than other air purification systems. Its innovative fan design allows for more efficient air circulation and is quieter than prior models.

RxAir which is a wholly-owned company of Vystar Corporation manufactures innovative medical products. The RxAir Rx3000 UVHEPA air purifier an FDA-approved class II medical instrument can remove 99.9 percent of the airborne bacterium as well as viruses and particulates by exposing them to special UV-C light over extended times. It also uses HEPA filters to guarantee the best quality of air.

Smart Air

All over the world, Smart Air hospital air purification systems are utilized to ensure a top-quality atmosphere is provided for personnel and patients. Hospitals are known to have a high volume of air and the Smart Air Blast COVID-19 purifier can clean huge volumes of air each hour. In the Philippines, as an example, many major hospitals employ their Smart Air Blast. In Singapore, over 3000 patients in hospitals suffer from harmful pollutants in the air each day.

Despite their popularity, however, portable air purifiers can not completely remove all the contaminants that exist in the air. Although a HEPA filter is most effective in taking in particles of any size, however, other air purifiers aren’t as efficient. Air purification systems that are portable have some disadvantages, which make them not appropriate for every hospital. While they can reduce the number of patients who are exposed to airborne pathogens HEPA filters aren’t able to eliminate all contaminants and that’s the reason hospitals need to come up with a viable solution.
