Air flow is an important factor when it comes to choosing the right air filter for your home. The higher the MERV rating, the more efficient the filter is at trapping small particles. But what is the difference between MERV 8, 11 and 13 filters? MERV 8 filters are the most common type of air filter used in residential homes. They are effective at trapping large particles such as dust, pollen and mold spores.
However, they are not as effective at trapping smaller particles such as pet dander and bacteria. MERV 11 filters offer additional protection against pet dander, dust mites, smoke particles and dust that can damage the lungs. This is a good choice for homes with pets or those looking for even better air quality than what the MERV 8 can offer. It is also our most popular type of air filter.
MERV 13 filters are rarely used in residential homes, except for people with extreme filtration needs, such as an immunocompromised person or someone receiving palliative care at home. They offer the highest level of protection against airborne bacteria and viruses that spread through airborne droplets. When choosing an air filter, it is important to consider your family's needs and environment. Pleated filters that are MERV 8 to 13 can effectively filter small particles and lower pressure drop.
If you have pets, you may want to use a MERV 10 filter to control their dander, which tends to have smaller particles than other contaminants. Additionally, using an indoor air quality monitor can help you determine if a separate air purification system is needed. Filter technology has grown by leaps and bounds over the years, and MERV ratings are designed to help us find the most effective and efficient air filter options for heating and cooling systems and beyond.
