Higher MERV ratings (from 13 to 16) are needed to remove bacteria and smoke particles. The home air filters you're looking for are rated anywhere between MERV 5 and 13. This is unlike the lower-grade HEPA filters (H10 to H12), which traps 85% to 99.5% of contaminants of 0.3 microns of size in the air. (Per the EPA) HEPA and MERV filters are usually not the same. With a MERV rating between 13 to 15, they are capable of catching very … 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. HEPA filters are generally known as the best of the best of air filtrations. CAUTION: HEPA Type and HEPA Like Unlike True HEPA, “HEPA Type” and “HEPA … 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. Although, they are an expensive filter. MERV rated filters are typically used in air conditioning systems, including systems found in most homes. These filters remove at least 99.97% of dust particle and are capable of removing viruses and radioactive material. And he said we should "absolutely" look at the MERV 13 filters for our homes. HEPA is a type of pleated mechanical air filter. HEPA Filter. HEPA is used for laboratory/medical facilities where clean air is critical. For instance, in order for a filter to obtain a MERV-13 rating, the filter must be able to capture at least 50% of E1 particles, 85% of E2 particles, and 90% of E3 particles. Some filters have a static electrical charge applied to the media to increase particle removal. These cheap filters ironically aren’t tested either since they fall into the lowest category anyway. High-efficiency particulate air (HEPA), also known as high-efficiency particulate absorbing and high-efficiency particulate arrestance, is an efficiency standard of air filter.. Filters meeting the HEPA standard must satisfy certain levels of efficiency. (For reference, the average strand of hair is around 40 microns.) The question to be asked is can you clean your electrostatic cells for less than $500? It does not have a Clean Air Delivery Rate (CADR) which is the standard for measuring the effectiveness of air cleaners. Minimum Efficiency Reporting Value – MERV. Electrostatic Filters vs High-Efficiency Pleated Filters - If your furnace is capable of using a high-efficiency pleated filter, these are an excellent choice. EPA also opines that: "Filters with a MERV 7-13 are likely to be nearly as effective as true HEPA filters at … The Minimum Efficiency Reporting Value (or MERV) rating is a rating system used to compare filters made by various manufacturers. The high-end filters can filter particles as small as 0.3 microns with 75 percent efficiency. This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). MERV 13 air filters are the best option for homes with members that need a clean indoor air environment. MERV Rating recommendations are based on outdoor concentrations of fine air pollutant particulate matter (PM 2.5 ) averaged from 100 of the world’s most populated cities. Here is a handy guide from Wikipedia: The MERV Rating Scale. High efficiency filters, also known as HEPA filters, have MERV values of from 17 to 20 and will catch at least 99.97 percent of indoor air pollutants. In general, manufacturers of HEPA filters market their products to allergy and asthma patients. ... NIOSH and HEPA. True HEPA filters with a MERV between 17 and 19 are can handle between 99.97 percent and 99.99 percent in removing 0.3 ìm particles, with a MERV of 20 being rated for 0.1 to 0.2 ìm particles. Ratings of 15-20 can filter many viruses. HEPA stands for High Efficiency Particulate Air filters and they are super-efficient. 13 89-90% >98% Proplet Nuceli (Sneeze) Superior Commercial Buildings Box Filter- Rigid Style Cartridge Filters 6 to 12" deep m ay use lofted or paper media. 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. ASHRAE is recommending that MERV 13 filters be used where possible, with MERV-A 13-A or MERV 14 preferred. What is the H13 HEPA Filter? HEPA (High-Efficiency Particulate Air) filters enjoy a generally positive view with consumers. Since you probably have no clue how large the particles are of different toxins, these are the ones the MERV 13 will filter out that the others cannot: bacteria, viruses, tobacco smoke, and any microscopic allergens. —Preceding unsigned comment added by 131.204.140.40 20:37, 19 June 2009 (UTC) These filters can be beneficial for allergy and asthma sufferers and those who are vulnerable to infections because they trap very small particles like mold spores, pollen and bacteria. For reference, a typical dust particle is between .2 and 8 microns, while pollen starts at … Compare a MERV-17 to MERV-19 HEPA filter rating to the inexpensive fiberglass filters that are found in most average American homes. 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). This is pushing the use of higher efficiency filters in many buildings. 12 70-75% >95% 1.0-3.0 pm Particle Size Superior Residential Bag Filter- Nonsupported Legionella microfine fiberglass or 11 60-65% >95% Humidifier Dust Better Commercial Buildings High efficiency particulate air (HEPA) filters are more efficient than MERV 16 filters. MERV means Minimum Efficiency Reporting Value. A possible explaination is that the number is refering to the filter's MERV rating. A MERV rating is to ensure that the incoming ventilated air meets area specific air quality standards. A medium efficiency MERV pleated air filter in the range of MERV 5-13 is, according to the US EPA, reasonably efficient at removing small to large airborne particles. At the top of the scale are HEPA filters with MERV ratings from 17 to 20, which can filter out particles smaller than 0.3 microns, including some viruses. At 3M, we believe MERV only tells part of the story. A HEPA boosts a MERV 17 ranking. All HEPA filters must be able to trap particles at 0.3 µm. Filters that are MERV 16 through 20 are usually only found in hospitals, cleanrooms, and nuclear power plants. One typically does not put a high MERV filter before a low MERV filter because the majority of the particulate would be filtered out by the expensive filter, and not the cheaper filter. AKA a MERV 12, MERV 13, or MERV 14 filter. The latter only have a MERV rating between 1 and 4. It is the standard that all air filters are rated through their process and effectiveness. You’ll see that HEPA air filters are usually rated from 15-20 on the MERV scale. The HEPA standard traps very small particles, many of which are invisible to the human eye and harmful to your health. Brand A – MERV rating of 13 may be able to remove pet dander whereas Brand B – MERV rating of 13 may not be able to. What Is A HEPA Filter? One thing we need to make clear – this device is not a HEPA air purifier. So you need to know if your system can handle it. The “Box Fan with a MERV 13 Filter” should be a useful tool in the fight against Covid-19. Further testing needs to be done with higher MERV ratings and over longer periods of … Well, MERV ratings range from 1 to 20, with 1 being the lowest level of filtration, and 20 being the highest. Generally, a MERV rating of 5-8 can remove dust mites, pollen and other allergens. HEPA and ULPA filters are represented in the 17 through 20 ratings. MERV ratings will range from 1 (low efficiency; minimum filtration) to 20 (highest efficiency; highest filtration). In short, our MERV 13 filter is the only one that has been tested to effectively filter out particles smaller than one micron. HEPA vs High Efficiency Air Filters: As a quick side-note to summarize these filters, there are many people throughout the industry that call these higher MERV filters “HEPA” filters – and they are not. For most household uses, the highest MERV rating used will be MERV 13 filters. While MERV ratings reflect a filter's ability to trap both microscopic and macroscopic particles, MPR ratings only grade a filter on its capacity to remove particles from 0.3 to 1 microns. MERV 13 furnace filters will prevent the circulation of bacteria, virus carrying agents, and more. Hospitals use air filters with a 13 to 16 MERV rating. The cost of operation is important in the HEPA vs Electrostatic comparison MERV 13 air filters offer the ultimate in air protection for any domestic residence. To provide perspective for size, human hair is approximately 80-100 microns in diameter. If you want it to filter even VOCs (volatile organic compounds), your filter needs a rating of 13-17. A low ranking filter is rated 1-4 MERV, and medium filter falls into the 5-13 MERV range, and high-efficicency filter will range from 13 to 16 MERV. It is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. The HEPA filters would have the cost of $500 per year the time required to clean the electrostatic cells would be about 12 hours.
