Commercial Building Air Filtration During COVID-19. “If it’s not installed well, a lot of the air can be going around the filter instead of through it.” With that said, Siegel recommends a filter with an efficiency rating of at least MERV 13. Increasing the air particle size range to 3-10 microns, a MERV 13 filter will catch 90% or more of them while at its worst. . However, you'll probably want a higher-MERV-rated filter if you are trying to stop unattached COVID-19 particles. MERV 13 furnace filters will prevent the circulation of bacteria, virus carrying agents, and more. A MERV 13 filter will likely be of help if the goal is to prevent droplets from passing through. If you can’t find a MERV 13 filter, then it’s okay to use whatever one is available to you (eg, a MERV 11 or a MERV 9 filter) It does increase the noise level in the room, so if you need to shut it off to hear, that’s okay. MERV 13 air filters offer the ultimate in air protection for any domestic residence. This value is helpful in comparing the performance of different filters The rating is derived from a test m Theses filters have success filtering very small particles out of your air, even smaller than a single micron. By Patrick Hearn July 10, 2020 The coronavirus has, for now, changed the way we approach our day-to-day lives. According to ASHRAE most modern HVAC systems can function properly with an air filter rated as MERV 13, especially for systems with a 2" or 4" thick filter. Even though pleated filters do have a slightly higher initial pressure drop, it is not so significant as to cause any harm to your HVAC system, as long as you’re changing your filters regularly. MERV 13 filters have also proven effective at stopping viruses, including the common flu. MERV-13 Is approximately equivalent to F7, a rating used in the EU. These include mold, smoke and pollen. Run … Filters with a MERV rating of 13 to 17 are normally used in hospitals and nursing homes. Air Filtration Experts Explain MERV-13 Filters. Minimum Efficiency Reporting Values, or MERVs, report a filter's ability to capture larger particles between 0.3 and 10 microns (µm). Show us the data! Research has shown that the particle size of the COVID-19 virus is around 0.1 µm (micrometer). However, the virus does not travel through the air by itself. They are ideal for removing bacteria from the air. 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. He recommends all schools have at least a MERV-13 filter in place in their mechanical filtration systems. Enter MERV 13 air filters. The Covid-19 diameter is around 0.1 micron. Similarly, if a building's HVAC system can't handle an extremely efficient filter like a HEPA or a MERV 13, then install the best filter that the system can handle. Using MERV 5-8 filters will keep your HVAC system more efficient than using higher rated filters, as long as you replace your filters regularly. Using an air filter with a MERV rating of about 5 to 8 is appropriate for most residential homes. MERV 13 Filters Recommended for COVID-19 - Video by Camfil USA Expert Joe Randolph Explains Riverdale, NJ // PRODIGY: PRESS RELEASE WIRE // In a new video, air filtration experts Mark Davidson and Joe Randolph discuss the available options for upgrading the air filtration systems in buildings with limited space for air filters. The poorest performance of the filter on all three particles sizes during each of the 6 cycles is used to determine the filters MERV rating. MERV 13 air filters are the best option for homes with members that need a clean indoor air environment. MPR (Microparticle Rating) is a rating system that includes microscopic particles not visible to the naked eye. A filter with a MERV rating of eight to 16 can remove these pollutants from the air. In fact, HEPA air filters are best at capturing particles as small as the coronavirus. We call that filter bypass and it’s really important,” Siegel says. There are usually gaps around it. MERV 14 is preferred. They're not inexpensive, but it has the ability to filter out smaller particles and it seems like a pretty good investment right now.” Freeland cautioned that replacing a current MERV rating in the furnace to a higher one (such as MERV 13) can also increase the pressure … Cognizant authorities such as the CDC and ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) recommend an air MERV rated filters are typically used in air conditioning systems, including systems found in most homes. And as you can see from the chart, MERV 13 filters are 85% efficient at removing particulates from the air at that 1.0 - 3.0-micron range and 90% efficient in the 3.0 - 10-micron range. HEPA filters are the most efficient for residential or commercial use, followed by MERV 13-16 filters. At 3M, we believe MERV only tells part of the story. July 22, 2020 GMT. There is no obvious answer to this question given unknowns about the nature of SARS-CoV-2 containing particles and droplets. Portable air cleaners and HVAC filters can reduce indoor air pollutants, including viruses, that are airborne. Central furnace or HVAC filters are designed to filter air throughout a home. If a MERV 13 filter is not a viable option in the HVAC system, then use the highest MERV rating you can. Another reason for having MERV 13 or higher rated filters in your units is because the COVID-19 virus attaches itself to droplets and droplet nuclei that are predominantly 1-4 microns in size. When you want the best possible air filter for your home, microparticles matter most — they make up 99% of the particles that are in the air. A MERV 13 filter will trap, at its minimum efficiency- or in other words, when it is doing its worst, less than 75% of air particles that are 0.3-1.0 micron in size. There is mounting evidence that MERV 13 rated HVAC air filters reduce and remove these droplets and particles. MERV 5 – MERV 8 filters provide good filtration and will remove most pollen, mold spores, and dust mites. In an interview with Propmodo , Paul Soames explains why they suggest MERV 13, “First, you have to look at what their system is equipped to handle in upgrading MERV filters to a higher level. However, the airflow restriction of these filters causes a significant pressure drop. But, in a counter-intuitive twist, the 4-inch thick filter yielded an airspeed of 460 feet per minute. They may negatively affect certain HVAC systems. What is the particle size of the COVID-19 virus? Pleated filters that are MERV 8 to 13, unlike fiberglass, can both filter out small particles effectively and diminish pressure drop (this here is as close to MERVana that you can get). Many schools have a lower-strength filter, around a MERV-8 or 9. More effective filters with reasonable pressure drop are available, and some increased pressure drop often results in an acceptably small effect on system performance. Air purifiers with HEPA filters are incredibly effective at capturing the coronavirus that causes COVID-19. The higher you go on the MERV scale, the stronger your filter; MERV filters with a value of 13 to 16, for instance, can keep particulates as small as 0.3 microns from entering an enclosed space. Manufacturers say they can't meet demand for MERV-13 filters, which are recommended by the CDC to control the spread of coronavirus indoors. By themselves, portable air cleaners and HVAC filters are not enough to protect people from the virus that causes COVID-19. For this reason, the pressure and airflow delivered by the ventilation system must be considered before specifying a filter. MERV 13 Filters Recommended for COVID-19 ... Refrigerating, and Air-Conditioning Engineers) recommend an air filter with a minimum rating of MERV 13. MERV stands for Minimum Efficiency Reporting Values, or MERVs, report a filter’s ability to capture larger particles between 0.3 and 10 microns (µm). Our Filters and Service Come with 100% Satisfaction Guarantee. A 1-inch thick MERV-13 filter dropped that to 320 feet per minute. It is suggested to have the fan run continuously and change filters every 30 days. 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. Can air purifiers with MERV-13 filter protect you from the coronavirus? We do not recommend M 12 or higher 13 filters. It will by no means catch everything, no filter will, but a MERV 13 will catch a significant number of particles between 1 and 5 microns, and a good number of ones even smaller than that. We do know that low efficiency filters (e.g., less than MERV 8 according to ASHRAE Standard 52.2 or less e PM 10 50% according to ISO 16890-1:2016) are very unlikely to make a difference. The filtration system exposes the coronavirus to levels of heat the virus simply can't withstand. Researchers have developed an air filter capable of killing the coronavirus on contact. (Per the EPA) HEPA and MERV filters are usually not the same. Use this type of filter if you or someone in your home suffers from a chronic illness that weakens the immune system. What filter should I use to protect those in my building from COVID-19? MERV 13 filters are in short supply in some places. Typically you have a MERV 8 — MERV is a rating system for filters — and those capture less than 50 percent, it could be down to 20 percent of small particles.
