Enhancing Indoor Air Quality
with 20x24x4 Air Filters
Learn how 20x24x4 air filters can improve the air quality in your home and create a healthier living environment.
Understanding Air Filters
Maintaining Air Flow
A well-fitted filter with the
right MERV rating ensures
proper air flow, reducing
strain on the HVAC
system and leading to
energy savings and
extended system
lifespan.
Ensuring a Proper Fit
Make sure the filter fits
tightly in the slot to avoid
gaps, which can reduce
air quality and system
efficiency. Larger filters
capture more particles,
improving air quality.
Understanding
MERV Ratings
MERV (Minimum
Efficiency Reporting
Value) ratings indicate
the filter's ability to
capture different particle
sizes. Higher MERV ratings
(8-13) are better for
allergen and dust
reduction.
Choosing the Right
Size
Determine the exact
dimensions of your
current air filter, listed as
length, width, and
thickness (e.g., 20x24x4).
Write down these
measurements to find an
exact replacement.

How 20x24x4 Filters Work
Regular replacement of
20x24x4 filters (every 90
days or as needed)
ensures optimal
performance and air
quality. This helps your
HVAC system run
efficiently, leading to
energy savings and a
longer system lifespan.
Maintaining
Efficiency
As air flows through the
HVAC system, the
20x24x4 filter's dense
media traps
contaminants,
preventing them from
recirculating back into
your living space. This
improves indoor air
quality and reduces the
strain on your HVAC
system.
Filtration
Mechanism
20x24x4 refers to the
filter's length (20
inches), width (24
inches), and thickness
(4 inches). The right
filter size ensures
effective filtration and
proper airflow through
your HVAC system.
Understanding
Filter Dimensions
MERV (Minimum
Efficiency Reporting
Value) ratings indicate
the filter's ability to
capture different
particle sizes. Higher
MERV ratings (8-13) are
recommended for
residential use,
trapping allergens, dust,
and even smaller
particles like bacteria
and smoke.

Filter Installation Tips
Inspect and Clean Compartment
Visually inspect the filter compartment and clean it if
necessary to ensure a proper fit and seal for the new filter.
Ensure Proper Airflow Direction
Align the new 20x24x4 filter's airflow direction arrows with the
HVAC system's airflow, typically pointing towards the blower.
Insert Filter Snugly
Insert the new 20x24x4 air filter into the compartment,
ensuring it fits tightly without any gaps to maximize filtration
efficiency.
Secure Filter Compartment
Carefully close and secure the filter compartment, making
sure it is properly sealed to maintain optimal HVAC system
performance.
Turn Off HVAC System
For safety, ensure the HVAC system is turned off before
beginning the filter installation process.
Locate Filter Compartment
Identify the filter compartment, typically located near the
return air duct, where the old filter will be removed and the
new one installed.
Gather Necessary Tools
Have a screwdriver or other tools ready to open the filter
compartment and securely install the new 20x24x4 air filter.
Carefully Remove Old Filter
Gently remove the old filter, taking care to avoid spreading
any accumulated dust or debris.

Frequently Asked Questions
Can I use a 20x25x4 filter instead
of a 20x25x5?
No, you cannot use a 20x25x4 filter in
place of a 20x25x5 filter because the
thickness is different. Always use the
filter size recommended by your HVAC
system's manufacturer.
What MERV rating is best for
COVID-19 protection?
Use an air filter with a MERV rating of 13
or higher to capture at least 90% of
virus-sized particles, including COVID-19.
MERV 11 filters also help, but MERV 13 or 14
filters are even more effective.
How often should I change my
20x24x4 air filter?
You should change your 20x24x4 air
filter every 3 to 6 months, depending on
your home environment and usage.
Homes with pets, in dusty areas, or with
frequent HVAC use may need it
changed every 2-3 months.
What is the best MERV rating for
air filters?
For residential homes, a MERV rating of 8
to 13 provides the optimal balance
between air quality and system
efficiency. Higher MERV ratings offer
better filtration but can restrict airflow.
