Frequently Asked Questions
Best MERV Rating for Home
A MERV rating between 8 and 13 is typically best
for home use, balancing effective air filtration
with minimal impact on airflow.
Thicker Filters & Airflow
Thicker air filters can potentially restrict airflow if
the HVAC system is not designed to
accommodate them, but many systems can
handle thicker filters.
1-inch vs 4-inch Filters
Using a 1-inch air filter instead of a 4-inch filter is
not recommended, as it can lead to reduced
filtration efficiency and increased strain on the
HVAC system.
Exact Filter Size
Recommended size of air filters for HVAC systems
matches the specifications precisely to achieve
proper installation and operation.
MERV 11 for Residential
The residential environment benefits from MERV 11
filters due to their ability to serve households with
allergy patients or pet owners.
Cheap vs Expensive Filters
Affordable filters do not guarantee sufficient
filtration capabilities although they typically
require more frequent replacements.
