HVAC System Maintenance and Filter Replacement during the COVID-19 Pandemic. The CDC and OSHA have recommended installing physical barriers like plexiglass or another material, strip curtains, or impermeable dividers or partitions to separate workers from each other in meat, poultry, and seafood processing facilities. $27.74 $ 27. Infection often is a function of the length of time spent in an indoor space and the number of people in that occupied space. Simply adding UV to an existing system without consideration of these factors has not been demonstrated to have a benefit. 4.7 out of 5 stars 3,811. Filtration and irradiation are common methods of purifying contaminated air. Find out how environment, health, and safety (EHS) professionals […], We have a variety of webinars, online events, and virtual roundtables available free of charge to keep you informed and connected to other EHS professionals throughout the COVID-19 pandemic. A : Although ASHRAE does not recommend a specific MERV filter rating for preventing COVID-19 transmission, the organization suggests that upgrading systems in non-healthcare facilities to MERV-13 or the highest achievable level can be a worthwhile step in emergency response plans. Allowing HVAC systems to run even when buildings are unoccupied instead of shutting down systems on evenings and weekends. As we build the EHS Daily Advisor community, we are looking for professionals, managers, and executives to be a part of our Faces of EHS profile series as well as contribute thoughtful content that can help our colleagues in the field with their compliance and cultural efforts. The effectiveness of filtration varies depending on the type of filter used. High capture filters like those specified for Indoor airPLUS Certified Homes must be at least MERV 8. They need to take additional precautions in facilities that remained unoccupied during state stay-at-home orders. In order for air filters to have any impact on infectious disease transmission, transmission has to occur through the airborne route, filters have to be properly installed and maintained in appropriate systems to treat recirculated air, and filters have to be appropriately designed for the building in which they are used. This quality filter might be more effective than what you need, but it's a great choice nonetheless. For example, if the filter was tested with an air velocity of 492 FPM and was found to be MERV 8, the filter’s Minimum Efficiency Reporting Value would be MERV 8 @ 492 FPM. They remove the bulk of dust we see in homes and offices. “It is important for people to understand how air-filtration systems are supposed to work,” says Jeffrey Siegel, a professor in the Department of Civil & Mineral Engineering and an expert in indoor air quality. “Some may be frightened with the situation we are all facing right now, but the best way to protect ourselves, our families, and our communities is with evidence-based information.”. 1-4. 3.0 - 10.0 less than 20%. While hospitals and healthcare facilities may have HVAC systems with components like high-efficiency filters and UVGI that can effectively eliminate viruses, simple steps may help prevent or reduce infections in the workplace and include: While human transmission of the SARS-CoV-2 virus is new, some of the science around ventilation and infection control is decades old. 3.0 - 10.0 84.9%. ASHRAE (formerly, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers) issued an emerging issue brief on COVID-19 and airborne transmission. MERV 5 to 8 filters typically can trap dust mites and pet dander, but most residential HVAC service providers recommend MERV 9 to 12 filters as the best options for homes. Depending on the design of your system, a high pressure drop filter can also diminish the amount of air supplied into the environment, making the filter less effective as well as causing other problems with other parts of the HVAC system. They know infections occur in close contact between individuals, especially within 6 feet. MERV filters have a rating system… MERV 7, 8, 10, and so on—up to MERV 20. Filtration is specific to each select group of containments. They often rely on other systems and control strategies (e.g., UV lamps, humidity control, airflow management) to maximize the benefit from filtration. When used along with other best practices recommended by CDC and others, filtration can be part of a plan to protect people indoors. Similar to building filtration, there is no direct clinical evidence of the benefit of portable air cleaners for reducing infectious disease risk, but some benefit can be reasonably inferred for portable HEPA filters, provided they are appropriately sized (i.e., their removal rate is appropriate for the size of the room), maintained, and operated. This is why air filtration is only a small part of a solution as it does not address transmission from surface contact or from close contact between individuals. Infection control is not a typical occupational health concern outside of a hospital or other healthcare facility. What about ultraviolet (UV) lamps? Get it as soon as Thu, Dec 24. For Merv 8, 11 and 13 filters, we recommend that you change your filter at least every 3 months, however changing your filter every 2 months provides better filtration which provides healthier and cleaner air in your home. 74 ($4.62/Count) $34.99 $34.99. The filter can be used for up to 90 days, and it has a cardboard frame. Consider using natural ventilation, opening windows if possible and safe to do so. High-efficiency particulate air (HEPA) filters can capture over 99% of particles like bacteria and viruses. What precautions should I take when changing filters? You may need to install physical barriers like plexiglass panels when spacing desks or workstations is impractical. $5 - $10. 2-day delivery . FREE Shipping by Amazon. If you've got allergies or pets, this is a great choice. Benden likens the difference to an N-95 mask and a cloth mask—both are effective, but one is much stronger than the other. This information is meant to supplement that coming from global, national, and local health authorities and is specifically meant to address an issue that is not currently well-addressed. As with building filtration, the details are important, such as the efficiency and air flow rate of the air cleaner, sizing and placement within the space, maintenance and filter change, and the nature of space that is being cleaned. The best place for all COVID-19 information is your local, regional, and national health authorities. The Rheem filter has an FPR of 4 (or a MERV rating of 8), meaning it can remove pollen, pet dander, nuisance dust, and dust mite debris from the air, helping to minimize allergy symptoms and keep dust out of your home. Arrives before Christmas. Most home furnace filters have a MERV Rating around 8, which will take out pollen and dust. If possible, increase total airflow supply to occupied spaces. These are just recommendations. Can HVAC Filters Capture COVID-19? New. The Agency maintains a list of disinfectants for use against SARS-CoV-2. Disable demand-control ventilation controls that reduce air supply based on indoor space temperature or occupancy. There is no obvious answer to this question given unknowns about the nature of SARS-CoV-2 containing particles and droplets. $44 × Filtrete. But retrofitting an office building, a manufacturing or processing plant, or a warehouse with hospital-grade air filtration may be hard to justify. Filtration in building heating, ventilation, and air conditioning (HVAC) systems can be a part of an overall risk mitigation approach but is not generally regarded as solution by itself. Most importantly, they have dedicated staff who operate and maintain this equipment so that it provides the most possible protection. left hand navigation Skip to Search Results. As with building filtration, they are only likely to be effective in concert with other measures. MERV rated filters are typically used in air conditioning systems, including systems found in most homes. © 2021 Faculty of Applied Science & Engineering, Professor Jeffrey Siegel says filtration systems can be a part of an overall risk mitigation approach but is not generally regarded as a solution by itself. Engineering controls may have higher costs than administrative controls but may be necessary when practices like social distancing are impractical. Over time, this charge dissipates and the effectiveness often degrades to approximately the equivalent of a MERV 8 filter. All MERV 16, 213CBN, 413CBN, and 513CBN filters should be changed every 6 months. We do know that low efficiency filters (e.g., less than MERV 8 according to ASHRAE Standard 52.2 or less ePM1050% according to ISO 16890-1:2016) are very unlikely to make a difference. The EPA’s position is that while improvements in ventilation and filtration cannot eliminate the risk of SARS-CoV-2 transmission on their own, the Agency recommends taking precautions through HVAC improvements to reduce the potential for airborne transmission. These air filters are used to protect people or products from airborne contaminants. Get it as soon as Mon, Jan 4. Keep systems running longer hours, if possible 24/7, to enhance the two actions above. The National Air Filtration Association (NAFA) recognizes that while some higher-efficiency filters can remove particles that contain a SARS-CoV-2 virus, low-efficiency filters—less than MERV 8—are unlikely to make a difference. While social distancing and hand-washing are still the best ways to prevent the spread of the virus, some are raising questions about the role of indoor air-filtration systems and the efficacy of air filters in protecting from the virus. Public health authorities have not reached a consensus on whether the virus is “airborne” or “aerosolized.” The difference is that an airborne disease could be more easily transmitted than one borne by aerosolized particles. Updated Daily. Filters like a MERV 13 get you closer to 80 or 90 percent, or HEPA filters capture 99.97 percent of particles, so upgraded filters can be effective. The MERV scale (with values from 1 to 16) measures the effectiveness of filters. Many MERV 13 rated filters (note: non-A-rated filters) use an electrostatic charge to improve the efficiency of the air filter without having to use larger amounts of filtering material. Steam radiator heat was deployed following the global influenza pandemic of 1918 and 1919 to enable building occupants to open windows during winter. DNA and RNA from other viruses that are generally associated with droplets have been found on used air filters. Show all . 4.7 out of 5 stars 3,935. 74 ($4.96/Count) $35.99 $35.99. What does this mean? These filters can remove most cement dust, mold spores, animal dander, hair spray, and even smaller particles from air. Cloth face coverings and surgical masks are not recognized personal protective equipment that filter out particles. There is no direct scientific evidence of benefit, but some reduced exposure can reasonably be inferred based on the ability of some filters to remove relevant-sized particles and droplets. However, the details of the system are very important (e.g., design of fixtures, lamp type, lamp placement, airflow amount and mixing, etc.). These particles could hurt health and productivity.
