Frequently Asked Questions
Is MERV 11 too high for residential?
MERV 11 filters are a good choice for most homes, catching
allergens and small particles while still allowing adequate airflow.
However, in some cases a lower MERV rating may work better if
your HVAC system struggles with airflow.
What MERV rating is best for airflow?
MERV 8 to 10 filters are a popular choice, offering a good mix of
clean air and system performance. This range allows air to flow
easily while still capturing dust and allergens.
Will MERV 11 restrict airflow?
MERV 11 filters can slow down airflow a bit more than lower-rated
ones, but most newer HVAC systems can handle them without
major issues. It's still a good idea to check if your system is
compatible to avoid reduced efficiency.
What filters do HVAC techs recommend?
Most HVAC technicians recommend pleated filters with a MERV
rating between 8 and 12. These offer a good balance of clean air
and strong airflow, with the exact best choice depending on your
home's specific needs.
Is there a downside to high MERV filters?
High MERV filters block more particles but can also restrict airflow,
causing your HVAC system to work harder, use more energy, and
require more frequent filter changes. Make sure your system can
handle a high-MERV filter before using one.
Does it matter what brand of air filter I
use?
Yes, brand quality matters. Good brands usually offer better
filtration, longer-lasting performance, and more efficient
operation. Choose a trusted brand that meets industry standards
to keep your air clean and your HVAC system running smoothly.
