MERV
is the national and international industry standard classification system established by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE). An Aerostar oven air filter helps keep your HVAC unit running efficiently by removing dirt and reducing strain on the engine. MERV ratings allow you to know the efficiency and level of filtration that an air filter can withstand under normal circumstances.A dirty filter restricts air flow to your HVAC system's air controller, making it work harder to cool or heat your home. The MERV rating system is based on the size of particles that an air filter can capture and retain. The higher the MERV rating, the more efficient the filter is at capturing particles. For example, a 12x30x1 air filter with a MERV rating of 8 will be able to capture particles as small as 3 microns in size, while a filter with a MERV rating of 13 will be able to capture particles as small as 0.3 microns in size.
When choosing an air filter for your home, it is important to consider the size of the particles that you want to be filtered out. If you are looking for a filter that can capture smaller particles, then you should look for a filter with a higher MERV rating. On the other hand, if you are looking for a filter that can capture larger particles, then you should look for a filter with a lower MERV rating. It is also important to note that higher MERV rated filters are more expensive than lower rated filters.
This is because they require more material and are more difficult to manufacture. Additionally, higher rated filters may require more frequent replacement than lower rated filters due to their increased efficiency. In conclusion, when choosing an air filter for your home, it is important to consider the size of the particles that you want to be filtered out and the cost associated with purchasing and replacing the filter. A 12x30x1 air filter with a higher MERV rating will be able to capture smaller particles than one with a lower rating, but it may also be more expensive and require more frequent replacement.
