Indoor air in Hospitals require more Attention

Coronavirus outbreak severely hit healthcare centers. Hospitals, the epicenter of this pandemic situation. The surge capacity of the hospital is exceeded and the COVID-19 patients are placed in the general wards. Hospital air quality is contaminated with chemicals used in the laboratories and the air gets contaminated with patients sneezing, cough, and respiratory airborne contaminants. COVID-19 breakout has increased great demand for air purifiers. Hospitals need air purifiers or air cleaners for a safe environment as COVID-19 contaminants increase in air. Recently the World Health Organization admits that coronavirus is airborne. The patient comes to the hospital to cure themself. If the indoor environmental air is not properly maintained with proper ventilation or the best air purifiers, it will lead to serious health issues.

Why Do Healthcare Professionals Prefer HEPA air purifiers?

Healthcare professionals who work to help patients get well need to be protected from these airborne contaminants in the hospital environment. Hospitals or doctor’s offices where people come with diseases should not affect the healthy persons who support the patients. Since the concentration of contaminants is higher in hospitals. It is vital to take precautions to provide a healthy environment for the healthcare workers, patients, and supporting individuals.

As coronavirus spreads all over the world at a faster pace. There is rising demand for Personal Protective Equipment. The World Health Organization (WHO) has warned of the shortage of Personal Protective Equipment (PPE)  to provide for healthcare workers. The shortage of PPE endangers health care workers worldwide. Some hospitals that are emerged for COVID-19 emergency that has poor ventilation should possess air purifiers to reduce the risk of spread of coronavirus. The best air purification system that is affordable and effectively helps healthcare workers in the hospitals with reduced exposure to the virus-laden aerosols.

The hospital environment is exposed to a wide range of chemical contaminants. These chemical contaminants are emitted from various sources such as sterilants, anesthetic gases, laboratory chemicals, pharmaceutical drugs, disinfectants used for cleaning, and other gases that are emitted from the hospital buildings. Researchers analyzed and determined that health care workers in the hospitals are more exposed to indoor airborne contaminants. These Volatile Organic Compounds (VOCs)  will lead to enlarged health issues. Best air purification system or natural air purifiers with enhanced ventilation in the hospital is a must to maintain routine hygiene.

Proper ventilation with reduced air pollutants is vital for people with low immune systems or sick people in hospitals. High indoor air quality and a safe environment improve patient’s health and increase the efficiency of medical treatment. Health care professionals prefer air purifiers in hospitals for the betterment of medical facilities in a clean environment.

Can Air Purifiers Capture the Coronavirus?

Air purifiers with true shield HEPA filters can effectively capture airborne or viral-laden aerosols. Best air purifiers for homes with HEPA filters can effectively trap disease-causing germs that are greater than 0.1 microns in the air.

Coronavirus is spread through respiratory droplets that come when the person coughs and sneezes. When the health person comes in contact with the infected person or contaminated respiratory droplets then the individual gets infected by a coronavirus. Recent studies admitted that coronavirus spread even through respiration if the infected person survives in the air particles for 3 hours. It is determined the transmission distance is more than 6 feet.

HEPA air purifiers capture these airborne viruses or aerosols in the indoor environment and reduce the risk of the spread of the coronavirus. HEPA filters cannot kill the virus; it stops transmission of the virus in the air and the virus gets deactivated. The Air purifier or air cleaners with a series of filters help remove fine particles, dust mites, pollen, pet dander, harmful chemicals, gases, smoke, and more provides a clean and healthy environment.

How to Choose the Right Hospital Air Purifier

There are different types of air purifiers or air cleaners that are available. It is vital to understand the best air purifier for COVID-19. It is important to consider the design, features, technologies used, maintenance required for the air purifier while choosing the right purifier for hospitals.

  1. Medical Grade Air Purifiers Required For Hospitals

Air purifiers with HEPA filters and carbon activated filters are medical-grade air purifiers that can deactivate airborne germs and harmful chemicals that are present in the environment. As the concentration of these contaminants is more in hospitals these air purifiers are considered medical-grade air purifiers.

  1. Air Purifiers With UV-light And Ionizers Needed

UV light air purifiers are used to kill harmful germs in the environment. UV light with germicidal wavelength will kill the viruses, bacteria, or other pathogens that are present in the environment but this UV light is harmful to the health. Ionizers cause the particles to be positively charged and get attracted towards the purifiers. These negative ions bond with the viruses and bacteria and make them fall on the surface. 

  1. How to Choose the Best Air Purifier For a Hospital

The best air purifier for the hospital can filter and circulate enough air depending on the size of the room configuration. Clean Air Delivery Rate (CADR) rating measures the amount of clean air delivered in a given amount of time. This CADR rating is an important measure while purchasing the best air purifier for home or hospital or office. 

Centers for Disease Control and Prevention (CDC) recommends 6- 12 air changes per hour to reduce the spread of viruses and airborne infections. And therefore it is recommended to have the CADR rating should be at least six times the volume of the hospital area where the air purifier needs to be installed

The coverage area of clean air is another important factor that is to be considered. Coverage area represents the area of the particular for which the air is to be purified completely.

Air purifiers that work with low decibels have to be chosen so that the sound from the air purifiers do not disturb the patients sleep in the hospitals.

Air purifiers with a three-stage advanced air purification system are preferred for hospitals that remove germs, formaldehyde, toxic gases, VOCs, odor.


Coronavirus spread has increased patients to hospitals. There is a great demand for protective equipment for health care workers. The concentration of contaminants has increased and hence the risk of spread of viruses also increased. Health care workers prefer air purifiers to reduce the risk of spread of diseases and reduce exposure to harmful chemicals that might affect the health adversely. Air purifiers in the patient’s room help to provide efficient medical treatment and enhance the patient's health. The air purification system in the operating room helps reduce exposure to microbial infection, harmful chemicals, VOCs, and odors.
