Will a Merv 8 Filter Restrict Airflow?

If you're looking for an air filter that can clean and handle dust, mold, pollen, and bacteria, then a Merv 8 is the way to go. But it's important to remember that a higher Merv rating can reduce airflow. This is because the filter material is thicker, which creates more resistance. This means less air can pass through the filter.\When researching HVAC systems, it's essential to consider airflow.

This is because it affects the performance and longevity of your oven or air handler, as well as the comfort of your home. Using an air filter with a Merv rating that is too high or too low can be detrimental.\A higher Merv rating means better filtration, as fewer pollutants and dust will pass through the filter. However, this also means there will be greater resistance, which can decrease comfort, increase energy use, and accelerate wear of HVAC components. In particular, using an air filter with a too high Merv rating can damage the compressor, heat exchanger, and air conditioner coil.\It's important to note that using an air filter with a Merv rating that is too high can be just as bad as using one that is too low.

This is because it can restrict airflow and cause the AC coil inside or near your furnace or air handler to freeze cool. When this happens, moisture in the air will freeze and the coil will be covered with ice. This means your air conditioning system won't be able to do its job properly.\For households with smokers or pets, a Merv 11 air filter is recommended as it's better at eliminating odors. It's also important to remember that two Merv 11 filters can have the same filtering capacity but one could allow more air to be transferred.

On average, it's recommended that most homes and retail spaces have a filter with a Merv rating of at least 5 to 12 in the high-end.\Raising just three levels of Merv rating can make a big difference in terms of air quality and comfort. However, if you're concerned about outdoor air pollution or family members with respiratory problems or pets in the house, then it would be wise to go for a higher Merv rating.
