Frequently Asked Questions
Consequences of
Backward
Installation
A backward filter blocks
airflow, reduces HVAC
efficiency, increases
energy costs and fails to
trap pollutants properly,
allowing dust and
allergens to circulate.
Proper Filter
Orientation
Look for the arrow on the
side of the filter frame. It
should point toward the
HVAC unit or airflow
direction.
Filter Installation
Steps
Insert the filter with the
airflow arrow pointing
toward the HVAC. Ensure
a snug fit with no gaps
around the edges.
Importance of Filter
Direction
Yes. Installing it the wrong
way reduces filtration
efficiency, strains your
HVAC system and
shortens the filter's
lifespan. Proper
installation ensures
cleaner air and better
performance.
