"A number of NTD systems have emerged, which remove or reduce reliance on the operator to ensure distribution, contact time and process repeatability, and aim to improve the level of disinfection and thus mitigate the increased risk from the prior room occupant. Available NTD systems include hydrogen peroxide (H2O2) vapour systems, aerosolized hydrogen peroxide (aHP) and ultraviolet radiation. These systems have important differences in their active agent, delivery mechanism, efficacy, process time and ease of use. Typically, there is a trade-off between time and effectiveness among NTD systems. The choice of NTD system should be influenced by the intended application, the evidence base for effectiveness, practicalities of implementation and cost constraints."

Air cleaners are designed to make living space more comfortable by reducing pollutants that contribute to poor indoor air quality. By filtering common allergens like dust and pollen, they’re especially important for people suffering from asthma or allergies.

"Finally, hydroxyl radicals not only react easily with organic pollutants, but they are also very unstable in the air and are quickly reabsorbed to form water, so there is no possibility they would make it out of the device."

"EPA does not certify air cleaning devices. The Agency does not recommend air cleaning devices or manufacturers."

Great selection of effective residential antimicrobial air sanitizers at discount prices remove viruses, bacteria, germs, mildew, mold and other microbes.

****!!!!**** "This cold mist humidifier for the bedroom features an innovative electrolytic sterilization module to ensure a healthy indoor environment. Using just tap water, this humidifier runs the water through the electrolytic process to create slightly acidic electrolized water, which is a strong and natural disinfectant. Meanwhile, the humidifer's ultrasonic atomizer ensures that the electrolyzed water is converted into a hydroxyl mist, which removes odors, oxidizes contaminants, and kills viruses and bacteria. Independent testing has shown that this dry air humidifier consistently had an airborne bacteria kill rate of 99.9% in two hours."

EPA recommends precautions to reduce the potential airborne transmission of the virus, such as ventilation and air filtration as a part of a larger strategy that includes minimizing close contact, surface cleaning, handwashing, and other precautions.

The outbreak of SARS-CoV-2 has made us all think critically about hospital indoor air quality and the approaches to remove, dilute, and disinfect pathogenic organisms from the hospital environment. While specific aspects of the coronavirus infectivity, spread, and routes of transmission are still under rigorous investigation, it seems that a recollection of knowledge from the literature can provide useful lessons to cope with this new situation. As a result, a systematic literature review was conducted on the safety of air filtration and air recirculation in healthcare premises. This review targeted a wide range of evidence from codes and regulations, to peer-reviewed publications, and best practice standards. The literature search resulted in 394 publications, of which 109 documents were included in the final review. Overall, even though solid evidence to support current practice is very scarce, proper filtration remains one important approach to maintain the cleanliness of indoor air in hospitals. Given the rather large physical footprint of the filtration system, a range of short-term and long-term solutions from the literature are collected. Nonetheless, there is a need for a rigorous and feasible line of research in the area of air filtration and recirculation in healthcare facilities. Such efforts can enhance the performance of healthcare facilities under normal conditions or during a pandemic. Past innovations can be adopted for the new outbreak at low-to-minimal cost.

The purpose of this research is to evaluate spray parameters for several different types of sprayers and foggers. Specifically, we are evaluating six ESS, two foggers, and one hand-pumped garden sprayer
