“…The concentration of bacteria indoors can be suppressed by improving room conditions through better hygiene, lighting, and ventilation, and by maintaining optimum room temperature and humidity [4]. Utilizing hospital cleaning staff for thorough cleaning, activating the air conditioner, and regularly monitoring temperature and humidity are some actionable routines to suppress indoor bacteria concentration.The installation of an air purifier is another thing to consider [20]. We found the total bacteria count was reduced upon biosterilizer activation, and the most significant reduction in concentration was located near the air purifier.…”

“…A high concentration of bacteria in the air increases the risk of infection as many harmful bacteria can live there, such as Staphylococcus aureus, Staphylococcus p., Neisseria m., Corynebacterium diphtheriae, hepatitis B virus, and cytomegalovirus [20]. The concentration of bacteria indoors can be suppressed by improving room conditions through better hygiene, lighting, and ventilation, and by maintaining optimum room temperature and humidity [4].…”

Bacteria live and grow anywhere, especially in hospitals as a place of patient care. An infected person, when coughing and touching objects, will deliver the transmission to the surrounding environment. Air is a potential means for viruses and bacteria to act as intermediaries for the transmission of various diseases. Currently, many air purifiers have been manufactured and are expected to be able to suppress the growth of viruses and bacteria to minimize the potential for transmission. The study's goal was to see how effective a biosterilizer was at reducing bacterial loads in hospital treatment rooms after it was activated. The study inspected the indoor air quality of the internal medicine room and the emergency unit in Linggajati Hospital, Kuningan Regency. The examined parameters were PM10 particles, viral load, and bacterial load as determined through air sampling and the swab method at 27 points, both before and after placing the bio sterilizer. Samples were examined in the laboratory, and the concentration of airborne particles was tested by a multifunction air quality detector. Interviews were also conducted with hospital staff and patients regarding the benefits of this sterilizer. The analysis was carried out by assessing the difference in air quality before and after the placement of the biosterilizer. The results of the study showed that 24-h operation of a biosterilizer may reduce bacterial density by about 50% but is ineffective for reducing airborne particles (PM 10). According to officers and patients, the placement of the biosterilizer has a positive psychological impact and improves the condition of the room, reducing complaints of pain. Hospitals and other health-care facilities may want to consider using a biosterilizer to improve indoor air quality and provide better services.

“…It is important to mention that the outside air coming into both chambers had exactly the same properties, the flooring material in both chambers had the same composition and amount, and in Chamber A, an active plant-based system was place to evaluate its impact in the perceived IAQ. Regarding the RH levels, it is important to mention that any vegetation system generates extra humidity in the environment [33].…”

“…Previous studies have shown that perceptual reaction to different odors varies according to individual sensitivity, and in general, when the participants do not know the source of the smell or if they feel that the smell is potentially hazardous, they tend to reject the smell and show their discomfort [38]. Finally, the fact that an active plant-based system was introduced in Chamber A may introduce other pollutants and compounds into the chamber [20], such as mold [33].…”

Active plant-based systems are emerging technologies that aim to improve indoor air quality (IAQ). A person’s olfactory system is able to recognize the perceived odor intensity of various materials relatively well, and in many cases, the nose seems to be a better perceiver of pollutants than some equipment is. The aim of this study was to assess the odor coming out of two different test chambers in the SenseLab, where the participants were asked to evaluate blindly the level of acceptability, intensity, odor recognition, and preference at individual level with their noses. Two chambers were furnished with the same amount of new flooring material, and one of the chambers, Chamber A, also included an active plant-based system. The results showed that in general, the level of odor intensity was lower in Chamber B than in Chamber A, the level of acceptability was lower in Chamber A than in Chamber B, and the participants identified similar sources in both chambers. Finally, the preference was slightly higher for Chamber B over Chamber A. When people do not see the interior details of a room and have to rely on olfactory perception, they prefer a room without plants.

“…The presence of pathogenic organisms (viruses, bacteria or fungi) has a significant impact on health. It can cause long-term effects, worsening the quality of life for many months or years, even after infection, and in extreme cases, lead to disability or death [1,5,8,9,[11][12][13][14][15]. Currently, hospital risks are of particular concern.…”

The indoor air quality is of great importance for the health of people. Appropriate selection of methods, parameters and conditions for the analysis makes it possible to obtain the results that reliably reflect the actual state of affairs. The aim of this study was to compare the results of microbiological air analysis in selected rooms of the Biotechnology Center obtained using the sedimentation method and the impaction method. During the research, the SMA (for total bacteria number) and Sabouraud media (for total fungi number) were exposed to different times in sedimentation analysis and to different air volumes in the impaction method. In the case of the sedimentation method, significant differences were found in the total number of bacteria and fungi in 3 out of 7 rooms depending on the time of exposure. In the case of the impaction method, it was 4 out of 7 rooms for bacteria and 2 out of 7 for fungi, depending on the analysed volume of air. The comparison of the methods showed that 4 out of 6 rooms had higher number of microorganisms when impactor was used.
