MERV 12 filters are known for their high efficiency in trapping particles, with an average particle size efficiency of 90 percent or better. They are capable of trapping 80 to 89 percent of 1.0 to 3.0 micron average particles, making them a great choice for those looking for a reliable air filter. However, MERV 11 filters are just as effective and can be a more cost-effective option. MERV 11 air filters are slightly more expensive than standard filters, but they offer a higher level of efficiency.
This makes them ideal for those with allergies or respiratory problems, as well as homes with smokers or pets. They are also better at eliminating odors than MERV 8 filters. When selecting an air filter, it is important to consider the manufacturer's recommendations or consult an HVAC professional to determine the best MERV rating for your system. Generally, a filter with a MERV rating of 10 to 12 is sufficient to remove most allergy-causing particles from the air in your home.
MERV 8 and MERV 11 air filters have some differences, but both are suitable for residential use. The main difference is that a MERV 11 filter may need to be changed more frequently than a MERV 8 filter. This is especially important if you are worried about the effects of inhaling fine air particles. The MERV rating of an air cleaner is a scale from 1 to 16 that describes the minimum efficiency of the air cleaner.
A higher MERV rating indicates that the filter does a good job of removing particles from the air, but it may need to be changed more often. If you are susceptible to allergies, asthma, or other respiratory conditions, you may want to use a filter with a MERV rating of approximately 10 to 12. It is important to remember that if you use a higher MERV rating, you should change the filter more often (at least every three months) to avoid restricted airflow that can cause the system to operate inefficiently or even damage it.
