Media filters are tightly woven and can restrict a furnace’s ability to blow air through the house. To insure a steady, strong airflow through the house, choose a filter that matches your blower’s capacity.
Does air filters restrict airflow?
When an air filter is too efficient, it can cause low airflow. … However, they can work so well sometimes that they cause your HVAC system to be less efficient because they block too much airflow. This leads to higher energy bills and could damage your furnace if it overheats.
Do higher for filters restrict airflow?
Generally, a filter with a higher MERV rating will reduce airflow. However, there are many other factors at play such as the size of the filter and the type of blower motor in your HVAC system.
Do vent filters block air flow?
The biggest drawback of vent filters is restricted airflow. Filters slow the passage of air. As particles build up on them, the amount of obstruction increases. This can cause your system to work harder, using up more power and potentially overheating components.
Do pre filters restrict airflow?
Will adding a pre-filter reduce my airflow or horsepower? Adding a pre-filter will not have any significant reduction in airflow (independent lab test results available upon request). Most Performance air filters allow more air in than the engine can actually handle.
Does MERV 11 restrict air flow?
A MERV 11 air filter has a higher efficiency rating. … Air filters with higher MERV ratings can filter more, but the thickness of the filter material can restrict airflow. Restricted airflow can decrease comfort, increase energy use, and accelerate the wear and tear of HVAC components.
What MERV rating is best for air flow?
If your unit is older and/or very sensitive with airflow, use a filter that ranks from MERV 1 up to possibly MERV 6. If you want your air to at least be cleaned and handle dust, mold, pollen, and bacteria, then a MERV 8 will do the job.
Is MERV 13 too high for residential?
One factor to consider is air flow through the system. … In some cases, using an air filter that is too restrictive for your system may cause low air flow problems as well. MERV 13 is the highest MERV value safe for residential furnaces; the higher ratings are used primarily in commercial units.

Can I put filters on my supply air vents?
Do not put filters in your supply vents. Your AC system should have a proper fitting filter on the return side. By placing a good fitting, high quality filter on the return vent, you will remove particles from the air before they can enter the AC system. … Filters for supply vents are a bad idea.
Does Duct Cleaning improve airflow?
Ductwork cleaning does not improve air flow (and can actually help impede it), does not permanently remove mold or odors, and, depending on the type of ductwork, actually cause damage. Consult a certified HVAC specialist to determine the best solution to maintain your ductwork.
How do I increase the airflow in my vents?
