When used properly, air purifiers can help reduce airborne contaminants including viruses in a home or confined space. However, by itself, a portable air cleaner is not enough to protect people from COVID-19. When used along with other best practices recommended by the Centers for Disease Control and Prevention, operating an air cleaner can be part of a plan to protect yourself and your family.
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has developed proactive guidance to help address coronavirus disease 2019 (COVID-19) concerns with respect to the operation and maintenance of heating, ventilating and air-conditioning systems.
The most effective ways to improve your indoor air are to reduce or remove the sources of pollutants and to ventilate with clean outdoor air. In addition, research shows that filtration can be an effective supplement to source control and ventilation. Using a portable air cleaner and/or upgrading the air filter in your furnace or central heating, ventilation, and air-conditioning (HVAC) system can help to improve indoor air quality.
Apartments can have the same indoor air problems as single-family homes because many of the pollution sources, such as the interior building materials, furnishings and household products, are similar. Indoor air problems similar to those in offices are caused by such sources as contaminated ventilation systems, improperly placed outdoor air intakes or maintenance activities.
Promote a healthy learning environment at your school to reduce absenteeism, improve test scores and enhance student and staff productivity.
Indoor air quality (IAQ) problems are not limited to homes. In fact, many office buildings have significant air pollution sources. Some of these buildings may be inadequately ventilated. For example, mechanical ventilation systems may not be designed or operated to provide adequate amounts of outdoor air. Finally, people generally have less control over the indoor environment in their offices than they do in their homes. As a result, there has been an increase in the incidence of reported health problems.
People, young and old, spend most of their time indoors, whether in homes, offices, schools, nurseries, shops or cars.
We spend a large part of our time indoors – in our homes, workplaces, schools or shops. Certain air pollutants can exist in high concentrations in indoor spaces and can trigger health problems.
As evidence mounts that the novel coronavirus can be spread through infection-laden airborne particles as well as respiratory droplets, consumers have been wondering whether portable air cleaners offer protection. So, although I explored the do’s and don’ts for buying air purifiers in February — focusing on the benefits for those with allergies — it’s time for another look.
The risk of contagion is highest in indoor spaces but can be reduced by applying all available measures to combat infection via aerosols. Here is an overview of the likelihood of infection in three everyday scenarios, based on the safety measures used and the length of exposure
