The Power of MERV Ratings
High MERV Filters Capture
More Allergens
MERV 13 filters trap 98% of pollen and pet
dander, while MERV 11 filters remove 95% of fine
particles. MERV 8 filters catch 90% of airborne
particles, making it a versatile choice for many
homes.
Proper Installation is Key
Gaps around a filter can reduce its
effectiveness by up to 50%. Improperly sealed
filters cause HVAC systems to work harder,
increasing energy costs. Sealing small gaps
around the filter can lead to noticeable
improvements in dust reduction and fresher
air.
Regular Filter Changes are
Essential
The EPA recommends replacing filters every 60
to 90 days to maintain air quality. Clogged
filters release trapped allergens back into the
air, worsening air quality.

Next Steps: Improve Your Air Quality
Maintain & Monitor
Regularly
Replace the filter every 60-90 days (or
sooner with pets/allergies). Check vents for
dust buildup - if dust returns fast, recheck
the filter fit. Schedule HVAC maintenance to
optimize airflow.
Check Your Current Filter
Remove and inspect the filter for dust
buildup, a sign it's time for a change. Look
for gaps around the edges - unfiltered air
may be bypassing it. Check the MERV rating,
aiming for MERV 8 or higher for allergy relief.
Install Filterbuy Filter
Correctly
Ensure a snug fit with no loose edges or
gaps. Seal small gaps with foam tape if
needed. Filterbuy filters are designed for
simplicity and efficiency, allowing easy
replacement.
