Air Filter Ratings: MERV and Lifespan
MERV Ratings
MERV Ratings and
Filtration Efficiency
MERV stands for Minimum Efficiency
Reporting Value, which measures how
well a filter traps particles. A higher MERV
score indicates better filtration
performance.
MERV 8 to 12 filters provide good filtration
for common household pollutants, while
MERV 13 to 16 filters are better suited for
specialized environments that require
higher levels of air purification.
Filter Lifespan
Filterbuy 24x24x4 Filters
Filter lifespan is an important
consideration, as high MERV filters
capture more dust but may clog faster,
requiring more frequent changes.
Balancing MERV rating and lifespan
ensures optimal HVAC performance and
indoor air quality.
Filterbuy 24x24x4 pleated filters strike a
balance between high MERV scores and
extended lifespan, keeping your HVAC
system running efficiently and your
indoor air clean.

Frequently Asked Questions
Are MERV 14 filters worth it?
MERV 14 filters are great for homes with
severe allergy or asthma. They work well
in places needing very clean air, like
hospitals and labs. But for regular use,
they may be too restrictive.
Do more expensive air filters
work better?
Expensive air filters usually have higher
MERV ratings, meaning they trap smaller
particles and more contaminants.
Effectiveness depends on HVAC and
indoor air quality needs.
What's the disadvantage of the
highest MERV rated filters?
The main downside is reduced airflow,
which can make HVAC less efficient and
cause more wear and tear. This leads to
higher energy costs. Filters may
damage HVAC if system isn't built for
high efficiency.
What is the best filtration level
for an air filter?
MERV 8 to 12 works well for most homes,
providing good filtration while keeping
airflow strong. Higher ratings like MERV
13-16 trap more pollutants but can
reduce airflow, suitable for special
environments.
