The higher the filter rating, the smaller the particles it will capture and the higher the percentage of particles captured. Low-efficiency filters are generally within MERV 1-4 and high-efficiency filters are MERV 13 and later. The MERV scale is not linear; the difference between a MERV 6 and a MERV 8 is almost double in the percentage of particles captured.
Keep in mind that as the MERV rating increases, the filter becomes more restrictive and more pressure and energy will be needed to propel the air. Applicable to most commercial buildings, residences, industrial workplaces and paint booths. The MERV 8 filter is the minimum standard air filter that we recommend for residential use. Essentially, it is a widely accepted and widely used rating system for air filters that makes use of a scale of 1 to 16 to indicate efficiency and the degree to which the filter can trap contaminants in the air.
Therefore, the MERV rating system provides a standard for comparing a variety of oven filters from different manufacturers. At the heart of an optimally functioning HVAC system is an oven filter with the right MERV rating for you. For most Canadian homes, oven filters with MERV ratings in this range are sufficient to filter most airborne impurities. MERV ratings range from 1 to 20; the higher the number, the higher the percentage of contaminants blocked by the filter.
You advertise a size and then, when you get them, it says on the filter the actual size, so the filter wasn't the size I needed. Air filters with MERV 13 or higher are recommended for those who prioritize air quality and may have to manage asthma, severe allergies, and other similar circumstances. First, it takes time for the filter to charge sufficiently for a beneficial effect, so that everything that passes through the filter ends up in your system or in your home. It is essential to remember that the MERV rating of an air filter denotes its lowest possible capacity, that is, the minimum percentage of impurities it could effectively filter.
Ironically, the effectiveness of low-efficiency air filters increases as the filter becomes loaded with dirt and dust. Some technicians anticipate that people will forget to change their filters and regular use of low-efficiency filters could help minimize damage to a neglected HVAC.
