Many New Jersey homeowners ask us about MERV ratings, especially when it comes to choosing between MERV 8 and MERV 11 air filters. These filters remove at least 99.97% of dust particle and are capable of removing viruses and radioactive  material. 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. The LakeAir HEPA Air Purifiers are rated MERV 16 or better. The speed at which the test was done is noted in the test results. The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), established this rating under Standard 52.2: Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size. They are available for the home and business. Generally, the higher the MERV (M), you get better filter performance. These particles could hurt health and productivity. YES! The range is from 1 (lowest efficiency) to 20 (highest efficiency). It seems that most of the world is starting to turn the corner on COVID-19. A MERV 11 filter only needs to stop 20% of particles in the 0.3 to 1.0 micron (three to ten times bigger than a COVID-19 particle), a MERV 12 only needs to stop 35% of particles under 0.3 micron, and a MERV 13 only needs to stop half. Our UVGI filters kill microorganisms with a high volume of UV-C light. Here are answers that can make a difference for you now.
