As the leader in IAQ and whole-home
filtration, Aprilaire oers homeowners
and installers peace-of-mind and
assurance that all aspects of our filters
come together to provide you with the
best air purifier on the market today.
PURE FIT PROMISE
The Aprilaire Pure Fit
Promise guarantees a
filter that is not only
made to fit flawlessly
into an Aprilaire air purifier, but one that
also provides purer, healthier air.
SELF-SEAL FILTER
Our Patented Self-Seal
technology works like
this: the excess filter
on either side of the
Interlock Rails collect at the back and
front of the air purifier in order to create
a seal that allows no air to pass
by unfiltered.
INTERLOCK RAILS
The Aprilaire Interlock
Rail System allows our
high-performance air
filter to work without
unnecessary cardboard framing, or
plastic or metal reinforcements. It also
ensures that no air bypass occurs over or
under the filter.
CLEAN-COIL
GUARANTEE
Should a homeowner’s
indoor air conditioner
coil require a
professional cleaning at any time up to 10
years after being installed with an Aprilaire
air purifier, we will pay $100 toward that
cleaning by an HVAC contractor.
