HEPA
filters are very efficient at removing extremely small particles from small
volumes of air. However, HEPA filters restrict airflow in addition to
pollutants, so these systems can not be used to filter all of the air going
through a residential furnace.
Aprilaire’s air cleaner uses the same types of filtration as HEPA filters, but
with a lower restriction to airflow. This means you can filter all the air
moving through the furnace. Air can be cleaned throughout the entire home, not
just a single room. The complete line of Aprilaire air cleaners offers units for
general air cleaning needs and an electronic air cleaner that is the most
efficient (non-HEPA) residential air cleaner on the market.
The Aprilaire Electronic Air Cleaner Model 5000
offers the ultimate in efficiency, as there is no other whole house, full-flow
residential air cleaner on the market that is more efficient. The media will
typically last one year. If installed on a 5-ton system or in the presence of
high concentration of particulate, it may need to be changed more frequently.
The air cleaner media in the Models 2200 and 2400 can last up to 2 years. If
installed on a 5-ton system, in the presence of high concentration of
particulate, or if the furnace fan is on continuously, it may be necessary to
change the media more frequently. In any application, the life of the media is
dependant upon the total volume of air being moved through it as well as the
amount of particulate it is filtering.

All of the media types (201, 401, 501, 261, 275) are made of blanket glass micro-fibers.
Yes. There are airflow arrows on the inner
housings of all of our units, which indicate the proper direction for airflow.
The air cleaners must be installed in this manner to ensure proper support for
the air cleaner media. The correct installation allows the media to operate
efficiently and last a long time.
If an Aprilaire Air Cleaner is installed with the airflow moving in the opposite
direction of the airflow arrows, the efficiency of the Aprilaire is not affected
but the media may collapse and reduce its service life.

If you own an Aprilaire humidifier the answer is
very simple -- “Yes.” The humidifier will not have an adverse affect on the
air cleaner since the humidity being created is a vapor. It is our
recommendation that you contact the manufacturer of your humidifier for specific
application information if you do not own an Aprilaire Humidifier.

Many times an air cleaner is installed with a new
furnace capable of moving more air than the previous one. This causes the air to
pick up particulate sitting in the supply ductwork and carry it into the living
area. However, the furnace blower may not be strong enough to bring the
particles back to the air cleaner and so particulate appears on furniture,
tables and other home furnishings. The best way to reduce this is to run your
blower continuously and bring as much air back to the air cleaner as possible.
