A micron is a unit of measurement equal to one-millionth of a meter, sometimes called a micrometer. This value is helpful in comparing the performance of different filters The rating is derived from a test m Can an air conditioner make you prone to coronavirus? One thing we need to make clear – this device is not a HEPA air purifier. Simply put, MERV 16 filters are not ideal for most homeowners (as we’ll show below). There are usually gaps around it. Since COVID-19 is transferred from person to person and can be airborne, you might think an air purifier could reduce exposure. We also spoke with Molekule co-founder and co-CEO Dilip Goswami. Air purifiers use fans to draw in air and pass it through a filter before expelling the purified air out the other side. Market data provided by Interactive Data. Second, if faced with a MERV-13 regulatory mandate and budgetary concerns that prevent the first choice, then 2-inch MERV-13 (not MERV-13A) air filters could be sourced, but be aware that the actual performance of MERV 13 air filters will be closer to MERV-8 after a period of time. According to Snell, the size of COVID-19 is approximately 0.125 microns. “However, the technology is not just HEPA; air purifiers that utilize photocatalytic oxidation (PCO) release ions into the air that bind to these contaminants and destroy them. You definitely want to make sure that you are regularly replacing the filters. So, in theory, a MERV-13 filter might be able to filter viruses out of the air, depending on the specific virus. • Consider adding UVGI to the ventilation system to inactivate the virus. An air purifier, even one equipped to kill a virus, will often fail to catch a virus before it comes into contact with a person or surface. However, you'll probably want a higher-MERV-rated filter if you are trying to stop unattached COVID-19 particles. While it may be able to stop some viruses, it won’t stop them all, and there is no confirmed evidence that it can stop the spread of the coronavirus. “Molekule’s PECO technology has been shown to destroy airborne viruses, and we’ve conducted extensive testing on RNA-type and DNA-type viruses to demonstrate that,” he said, adding that the company is “currently working with the University of Minnesota to test the technology on a strain of coronavirus.”. MERV rated filters are typically used in air conditioning systems, including systems found in most homes. First, air passes through a sort of “pre-filter” that’s laced with carbon. Digital Trends hasn’t tested Molekule’s air purifier. Particulates are caught by this fabric, while the now-clean air is allowed to exit out the other side. Powered and implemented by Interactive Data Managed Solutions. 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 … Finally, we reached out to Dyson. MERV filters are not effective at filtering microbes and viruses until they are rated at 17 or better. Manufacturers say they can't meet demand for MERV-13 filters, which are recommended by the CDC to control the spread of coronavirus indoors. While Goswami’s claims are promising, the company has endured harsh reviews from Wirecutter and Consumer Reports within the last year. However, these machines are large and routinely cost more than $1,500 (sometimes, much more). • Ensure the filters fit properly in the filter housing and check for ways to minimize filter bypass. “There are air purification technologies that can destroy biological contaminants such as mold spores and viruses (such as H1N1 and SARS),” he said. Many advertisements hail the MERV-13 filter as a way to stop viruses, but the truth is more nuanced. What MERV filter is recommended for preventing the transmission of airborne illnesses such as COVID-19? The purpose of a filter, said Freeland, is not to “treat/remove” or “degrade/kill” COVID-19 or any other virus or pathogen. As people seek to protect themselves and their families, technology is one place they look to for answers. What filter should I use to protect those in my building from COVID-19?

Because our intention was to focus this study on high-efficiency HVAC filters, i.e., MERV 12 and higher, we selected MERV 12, MERV 13 and MERV 14 fil-ters because these high-efficiency filters are commonly used in homes. This means even the most powerful air filters would struggle to purge a virus from the air. A MERV 5 filter was selected as a com-parative filter. Quotes delayed at least 15 minutes. A 1-inch thick MERV-13 filter dropped that to 320 feet per minute. In comparison, an N95 mask goes a step further and must filter out at least 95% of particles smaller than 0.3 µm. But, in a counter-intuitive twist, the 4-inch thick filter yielded an airspeed of 460 feet per minute. While filters may catch viruses, they don’t kill them. All rights reserved. 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. According to a representative, Dyson air purifiers will capture viruses, but won’t destroy them. All rights reserved. While there's no guarantee a strong air filter will protect you from the coronavirus, clean air helps keep your immune system strong. HEPA is an acronym for “high-efficiency particulate air.” PECO stands for “Photo Electrochemical Oxidation.”. Unfortunately, it seems like the end of this pandemic is still quite a ways off. MERV 13 air filters are the best option for homes with members that need a clean indoor air environment. According to the National Air Filter Association, a MERV-13 filter is able to remove 90% of particles between 3 and 10 microns in size, 85% of particles between 1 and 3 microns in size, and 50% of particles between 0.30 and 1 microns in size. Air purifiers are capable of filtering the air in a room over time, but viruses tend to travel short distances between people or land and linger on surfaces. Mark Marston slides a MERV 13 air filter into the HVAC system outside Basics Fitness Center in Portland, Maine, on July 21. MERV 5 – MERV 8 filters provide good filtration and will remove most pollen, mold spores, and dust mites. The diagram below demonstrates that MERV 16 filters trap up to 96% of virus-sized particles *, to help prevent the proliferation of airborne viruses in the home. The particular strain of coronavirus that’s causing COVID-19 (known as SARS-CoV-2) measures between .05 and .2 μm in diameter. A slight margin of error is why air purifiers claim an effectiveness rate of 99%. 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 … Alen Corp, the company behind one of Digital Trends’ best air purifiers of 2020, recommended using a filter treated with an antimicrobial coating that’s claimed to kill mold, mildew, fungus, bacteria, and viruses on contact. (One study found it to be between .07 and .09 μm.) Even if the virus is captured, it would likely survive for some time. PECO filters work in a similar, but more complex way. Over time, the particles will accumulate on the fabric until it loses efficiency. Dyson went on to comment: “You definitely want to make sure that you are regularly replacing the filters … .”, There are two primary types of air filters: HEPA and PECO.

Learn more about indoor air in homes and Coronavirus (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. In a 2016-study by NASA , it was tested and proven that HEPA filters were most efficient (almost 100%) at filtering particles at 0.01 micron, below the normal 0.3 test standard for HEPA filters. This is something customers don’t always understand until it’s explained, Lucas said. 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. We call that filter bypass and it’s really important,” Siegel says. Wash your hands often, and wear a properly rated facial mask in places where you might be exposed to the illness. A final note. That’s why filters have to be replaced. Viruses are roughly 100 times smaller than bacteria, and typically range from 0.004 to 0.1 microns in size. 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. There is no obvious answer to this question given unknowns about the nature of SARS-CoV-2 containing particles and droplets. 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. The virus will remain alive inside the filter for as long as it typically survives. Some nonessential shops are closed, kids have been learning how to do their schoolwork from home, and social distancing has become a household term. HEPA and MERV filters are usually not the same. They’re particularly effective at removing odors and large particulates from the air. Be sure to change your filters regularly because clean filters … An air purifier can combat other causes of respiratory problems and improve the overall air quality in your home, but a standard HEPA filter can’t capture and destroy something as small as a virus.
