This rating system is defined in an ASHRAE standard (52.2), which specifies the performance required to meet each MERV level and the testing required. This means the blower on your HVAC equipment has to work harder to push air through the filter and therefore uses more energy. 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).

All filters have a MERV rating. We understand that homeowners and families want to stay safe—we do, too—so we encourage any customers with additional questions or concerns to give us a call at (504) 208-2071. 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. Two to five inch thick versions of these filters fit in box-like housings mounted onto the air handler and can last up to one year. HEPA, or High Efficiency Particulate Air filters, are designed for applications where contaminants must be trapped on the first go round. Remember that the air in your home is recirculated, so the same air will pass through your filter multiple times each day. Knowing the difference between MERV and HEPA filters will help you to select the option that is appropriate for your home in St. Rose, Louisiana. Many HVAC companies and distributors offer filters with a MERV rating between one and 20. HEPA, or High Efficiency Particulate Air filters, are designed for applications where contaminants must be trapped on the first go round. All air filters are designed to remove dust from the indoor air. This means one filter with a MERV rating of 14 may be able to remove volatile organic compounds, while a different filter with the same rating may not be able to achieve this same level of filtration. Bryans United Air Conditioning specializes in a variety of HVAC services, including indoor air quality improvement. Generally, a MERV rating of 5-8 can remove dust mites, pollen and other allergens. MERV stands for Minimum Efficiency Reporting Value. HEPA Filter. MERV means Minimum Efficiency Reporting Value. MERV stands for minimum efficiency reporting value. This helps to reduce allergy and asthma symptoms and helps to keep your home cleaner. This rating describes how effectively the filters remove particles and allergens like pet dander, dust, and pollen from the air. HVAC filters with a rating of 15 to 20 are meant to be used in residential and commercial structures where there is a strong concern about the potential spread of viruses. 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. Some particles naturally adhere to the fibers when they hit, while others get trapped by the curved contours of the fibers. They effectively destroy airborne particles and are extremely energy-efficient. HEPA stands for High Efficiency Particulate Air filters and they are super-efficient. A filter with a MERV rating of 13 to 16 is considered a high-ranking MERV filter and can remove up to 75 percent of all airborne particles 0.3 microns or greater from the air. HEPA filters are commonly thought to be the best of the best when it comes to HVAC air filters. "Everything handled with professionalism, care and good cheer." For example, you wouldn’t want viruses circulating in the air in a hospital, so the facility would probably be equipped with HEPA filtration.

This makes it 63% higher at the 60 minute mark, and 30% higher after 2 hours. Filters with a MERV rating of 13 to 17 are normally used in hospitals and nursing homes. This is not to say that MERV filters are poor quality in reality they are more than adequate for the needs of most homeowners. The standard rating system for filters is called Minimum Efficiency Reporting Value, or MERV. Ratings of 15-20 can filter many viruses. It is determined by testing a filter's performance when exposed to particles of a known size in the air stream. This means one filter with a MERV rating of 14 may be able to remove volatile organic compounds, while a different filter with the same rating may not be able to achieve this same level of filtration. Monrovia, CA 91016 Just be sure to remember that the higher the MERV rating, the better the filtration. Minimum efficiency reporting value (MERV) is a method of stating a filter's efficiency. TAMPA, Fla. — The American Society of Heating, Refrigerating and Air-Conditioning Engineers and the CDC recommend MERV 13 filters in schools, buildings and homes. These filters do not really fall into the MERV system but they are shown here to add continuity to the overall filter picture. For reference, a typical dust particle is between .2 and 8 microns, while pollen starts at 7 … According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), this filtration helps provide healthier indoor air quality.A filter's MERV number indicates how it's rated to remove these particles. I need some more thought though to … Accordin… They are ideal for removing bacteria from the air. Website Design and Internet Marketing By Ryno Strategic Solutions. The remaining particles are trapped when they are forced to collide with gas molecules in the filter. All Content Copyright © 2021 Bryans United Air Conditioning | Privacy Policy | Accessibility Statement | Sitemap. The truthful statement is, "Filters with a MERV rating below 11 have lower than 20% capture efficiency between 0.3 and 1.0 microns."
