Understanding the MERV Scale
The MERV (Minimum Efficiency Reporting Value) scale is
the gold standard for measuring an air filter's ability to
capture airborne particles. It ranges from 1 to 20, with
higher numbers indicating more effective filtration.
Filters with a MERV rating of 1-4 provide essential
protection, suitable for modest spaces like residential
homes. They capture larger particles like pollen and dust.
Stepping up to MERV 5-8, these filters handle more
demanding needs, such as in residential and
commercial settings. They capture a wider range of
particles, including dust mites and pet dander.
MERV Scale Essentials
Basic Filtration (MERV 1-4)
Robust Filtration (MERV 5-8)
The MERV 9-12 range offers advanced filtration, making
them ideal for residential use and commercial
applications. They excel at trapping smaller particles like
smoke and smog.
Hospitals rely on MERV 13-16 filters to maintain sterile air
quality in critical areas like surgery rooms, capturing
even the tiniest of microorganisms.
The highest end of the MERV scale, these filters are
designed for the most demanding environments, such
as cleanrooms, where they capture even the smallest
particles with unparalleled precision.

Choosing the Right Filter Size
Choose a replacement
filter that perfectly
matches the length,
width, and depth of
your HVAC system's
filter housing. A precise
fit is essential for
optimal airflow and
filtration performance.
Select Exact Fit
Determine the exact
length, width, and
depth dimensions of
your current HVAC filter.
This information is
crucial for finding the
perfect replacement.
Measure Existing
Filter
Compare the
measurements of your
existing filter to the
recommended size for
your HVAC system. The
new filter must match
the dimensions exactly
to avoid gaps that
allow unfiltered air to
bypass the system.
Compare
Dimensions
Consult your HVAC
system's manual or
manufacturer to verify
the recommended filter
size for your specific
unit. This ensures the
new filter will fit
properly.

The Importance of Regular Filter Changes
Improve Indoor Air
Quality
Regularly changing HVAC
filters helps trap more
dust, allergens, and other
airborne particles,
keeping the air in your
home fresher and
cleaner.
Maintain HVAC
Efficiency
Clogged filters force your
HVAC system to work
harder, reducing its
efficiency and increasing
energy costs. Timely filter
changes help maintain
optimal performance.
Prevent Costly
Repairs
Neglecting filter changes
can lead to buildup that
damages HVAC
components, potentially
requiring expensive
repairs or even full
system replacement.
Recommended
Frequency
Experts advise changing
HVAC filters every 30-90
days, with more frequent
changes needed for
homes with pets,
allergies, or heavy use.

Allergies and
HVAC Air Filters
For individuals suffering from allergies, pleated
fabric or synthetic material filters are better
choices for HVAC systems. These types of filters
are more effective at trapping irritants and
allergens, providing cleaner, fresher air to breathe.
