They are used in light industrial and residential applications. Minimum Efficiency Reporting Value (MERV) Use this rating system compare filters made by different manufacturers. MERV stands for Minimum Efficiency Reporting Value. These air filters are great for people with pets. HEPAs are tested under a completely different test method, are typically a different size (24x24x11.50 exact vs 24x24x12 nominal) and HEPA filters are also defined by IEST standards. They are easy on fans but tough on dirt, Easy to install and lasts up to 12 months. A lint trap in a dryer is about M 2. They are available for the home and business. The speed at which the test was done is noted in the test results. What Merv rating should I use? The performance is based on particles that are 0.3-10 micron in diameter. This value is used at the filters lowest efficiency. 1.2 Underwriters Laboratories classified to UL 900 and ULC-S111-13. If equipment protection is your primary goal, than it is overkill to use a MERV 11 air filter as it takes out more than needed to keep your HVAC equipment adequately clean – which is why specifying/design engineers still write a lot of equipment specifications to have only MERV-6 or MERV-8 filters. These filters are used primarily to protect equipment. The Covid-19 diameter is around 0.1 micron. These products are great for cigar bars, hookah lounges and Vape Shops. At that particle size a MERV 11 air filter only removes 20% which isn’t enough to really offer health benefits to building occupants. The range is from 1 (lowest efficiency) to 20 (highest efficiency). Low air flow resistance. Is MERV-13 really the Best? The amount of E1, E2 and E3 dust particles that are captured and missed is calculated. Gross Media Area Adhesive Type MERV 13 PF13_012424 Pleated 24" x 24" x 1" 30 Pleats TB90 TB90 FILTERSFAST.COM Filter. Dust Mites. E2 arrestance is for the middle size particles. Please Note: Prices, promotions, styles and availability may vary by store and online. But is MERV-11 really Good Enough? It could be that because we’re in the Midwest and it’s part of our culture more than other places, but we are always seeking a compromise between High-Quality and Price. The resulting rating is theen given to each filter. read more. LakeAir offers four different levels of MERV Media filtration. In reality MERV 13 is the compromise filter for IAQ. These filters remove at least 99.97% of dust particle and are capable of removing viruses and radioactive material. Allergens and contaminants best removed by this filter: dust, lint, dust mite debris, pet dander, mold spores, bacteria, most smoke and virus carriers 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. Every air purification system should have an activated carbon filter. 940-45% >90% Welding Fumes. Inventory is sold and received continuously throughout the day; therefore, the quantity shown may not be available when you get to the store. 4.8 out of 5 stars 152 We’ll atempt to answer these questions.

Our HEPA filter systems are our “best” media air filters they remove 99.97% of all impurities. They require special blowers to pull the air through them. What is a Merv rating? Specially treated filters offer a higher capture rate for all Microbials including SARS-CoV-2 the virus that causes the disease COVID-19. The test results are then used to give a filter its MERV rating. MERV 13 furnace filters will prevent the circulation of bacteria, virus carrying agents, and more. . ASHRAE developed the MERV air filter efficiency rating system. So, whatever air filtration you choose, be sure it includes a carbon filter. The chart below shows the MERV ratings. They generally allow enough air to flow through a furnace filter to allow the blower to stay cool. Forgetting to change out a more efficient filter and letting it clog up could stop the airflow of your HVAC system, possibly resulting in significant damage and less than cheap repairs. MERV 9 through 12 filters are good filters for general home use. Our Healthy Living filters capture bacteria, cough and sneeze particles, and even viruses.

These particles are 1-3 microns. Here’s what we tell them: Think of MERV 8 filters as a “good” option, and MERV 11 filters as the “better” option for normal residential use. LakeAir replacement filters use 4 different MERV rated filters. Activated carbon filters remove VOCs and odors. Our filters are available in three grades – Merv 8, Merv 11, and Merv 13. The higher the MERV rating on a filter, the fewer dust particles and other contaminants that can pass through it. The process is repeated 6 times. It’s just that the real world applications where it fits is small and it should not be used for general HVAC purposes. 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. These include mold, smoke and pollen. MERV 7 to MERV 8, 8-A – Pleated panel filters for commercial buildings, rooftops, furnaces and as prefilters in built-up banks or housings. For protection of HVAC coils ASHRAE has long put forward that anything MERV-7 or higher is adequate as the “average” HVAC system without filters will accomplish MERV-6 with its coil. Microparticles are not even measured on the MERV scale until it reaches MERV 11. ASHRAE stands for the American Society of Heating, Refrigerating, and Air-Conditioning Engineers. MERV 13 air filters offer the ultimate in air protection for any domestic residence. Welding fumes and milled flour are this size. This graph shows the distribution of particles that are in the air – to no real surprise the smaller particles are the ones that stay suspended, or “floating” in the air while larger particles settle. Generally, the higher the MERV (M), you get better filter performance. How to Eliminate the Smell of Spray Paint? MERV Ratings 17-20 reflect values that are used in the rating of HEPA and ULPA filters. The test is based on particle size. They are usually reserved for superior commercial applications. I’ve got to give it to this filter manufacturer for actually printing the static pressure drop on the filter (shown above). These dust particles fall into three size groups.
