Air Quality Considerations and Best Practice of Air Filtration for Hospitals

Aug 29th, 2023 | Fon ZHOU

Brief Analysis of Hospital Air Pollution

The significance of maintaining optimal air quality within a hospital cannot be overstated. Hospitals operate within a unique environment that gives rise to a diverse array of air pollutants, including particles and pathogens. Given the presence of numerous patients, many of whom are already in a compromised state of health, addressing air quality becomes paramount. Patients with weakened immune systems are particularly susceptible to the adverse effects of these pollutants. Notably, pathogens such as viruses and bacteria can exploit air circulation systems to propagate, potentially leading to severe issues like nosocomial infections.

The potentially harmful pollutants that pose risks to patient and medial staffs well-being originate from both internal and external sources, each warranting careful attention.

External Pollutants:
External pollutants stem from sources of air contamination situated beyond the hospital's confines. Emissions from vehicle exhausts, industrial facilities, dust particles from construction activities, and other external processes contribute significantly to these pollutants. While the hospital's heating, ventilation, and air conditioning (HVAC) system aids in mitigating many of these contaminants, it's crucial to acknowledge that some pollutants can infiltrate the indoor environment through open doors and windows.

Internal Pollutants:
Internal pollutants encompass contaminants introduced into the indoor air environment through activities and individuals within the hospital premises. This category includes factors such as viruses transmitted through respiration, emissions from cleaning products, lingering kitchen odors, and other anthropogenic pollutants.

Addressing Air Quality Concerns

To ensure a healthy and safe hospital environment, several strategies can be employed. Regular maintenance and upgrade of the HVAC system will enhance its effectiveness in filtering out external pollutants. This step alone can significantly reduce the influx of contaminants. Moreover, strict protocols for cleaning and disinfection using low-emission products can minimize the introduction of harmful substances into the indoor air. Proper ventilation design and management can facilitate the dilution and removal of internal pollutants, curbing their impact on patients and staff.

More over, hospitals need suitable air filtration systems that can remove particulate matter and inactivate pathogens such as viruses and bacteria at the same time. And MESP air purification solution is a very good choice. In addition to the above-mentioned ability to remove various pollutants to the greatest extent, this technology uses the principle of electrostatic precipitation and automatically work with HVAC system to adsorb air particles, so its air resistance is much lower than that of conventional media filtration technology, resulting in great reduction of the energy consumption of the entire air conditioning system. The cost performance of long-term operation, as well as environmental protection and sustainability have all been very positively improved.
