Discover the ideal air filter replacement interval to maintain air quality and HVAC efficiency. Most filters should be replaced every 90 days, but homes with pets, high traffic, or pollution may require monthly changes. Regular replacements reduce energy costs, improve air quality, and extend your system's lifespan.

Replacement
Interval
Discover the ideal air filter replacement
interval for your home, ensuring optimal air
quality and HVAC efficiency.
Neglecting HVAC Air Filters
Dust and Debris
Buildup
Neglecting to change
your HVAC air filter can
lead to a buildup of dust
and debris, just like letting
it pile up at a busy
intersection.
Blocked Airflow
As the filter gets clogged,
it restricts airflow,
preventing your HVAC
system from functioning
effectively, just like the
intersection becoming
impassable.
Polluted Indoor
Environment
If your home feels more
like a bustling zoo or a
pollution-prone area,
failing to maintain your
air filter can lead to poor
indoor air quality,
affecting your health and
comfort.
Increased Energy
Costs
A clogged air filter forces
your HVAC system to
work harder, leading to
higher energy
consumption and rising
utility bills.

Optimal Replacement
Interval
Consistent Maintenance
Aim to replace your HVAC air filter every
90 days to maintain peak air quality in
your home.
Regular filter changes are key to ensuring
your system runs efficiently and provides
clean, healthy air.
Preventing Buildup
Improving Airflow
Replacing filters on schedule stops dust,
dander, and other airborne particles from
accumulating and clogging your system.
Fresh filters allow unrestricted airflow,
helping your HVAC work less hard and
consume less energy.

3
Factors Affecting Filter Life
Pets
Homes with pets experience increased dander
and other pet-related pollutants that can clog air
filters more quickly, requiring more frequent
changes.
Urban Environments
Bustling urban areas with higher levels of airborne
particles, such as dust, smoke, and dirt, can also
lead to faster filter clogging, necessitating more
regular replacements.
High-Efficiency Filters
While high-efficiency filters (higher MERV ratings)
are better at trapping small particles, they also
tend to clog up more quickly, requiring closer
monitoring and more frequent changes.
Usage Frequency
Homes with higher HVAC usage, such as during
peak heating or cooling seasons, will see their
filters become clogged more rapidly, calling for
more vigilant replacement schedules.

4
Signs It's Time to Change
If you find yourself
dusting your home
more frequently than
usual, it's likely that your
air filter is failing to
capture the airborne
particles, allowing them
to settle on your
surfaces. Replacing the
filter can help restore a
cleaner indoor
environment.
Constant Dust
Buildup
A spike in allergy
symptoms and
sneezing within your
home could indicate
that your air filter is not
effectively trapping
allergens like pollen,
dander, and dust.
Changing the filter can
help alleviate these
indoor air quality issues.
Worsening
Indoor Allergies
When your heating or
cooling system
struggles to maintain
the desired
temperature, it's a red
flag that your air filter
may be restricting
airflow. A dirty filter can
impair your HVAC's
performance, leading
to reduced efficiency
and comfort.
HVAC Efficiency
Decline
If you notice an
unexpected increase in
your energy bills, it
could be a sign that
your air filter needs
replacement. A clogged
filter forces your HVAC
system to work harder,
resulting in higher
energy consumption
and costs.

Understanding
HVAC Air Filters
The MERV (Minimum Efficiency Reporting Value)
is a scale that rates the effectiveness of HVAC air
filters in trapping airborne particles, from pollen
to pet dander. This nifty 1-20 scale provides a
standardized way to evaluate a filter's ability to
improve indoor air quality by capturing a wide
range of contaminants.
