Your Aprilaire®Air Cleaner is an investment in healthful
comfort for your family and protection for your home and
furnishings. With this purchase, you have invested in an air
cleaner that is many times more efficient than ordinary
furnace or air conditioning filters with which you may be
familiar. There are many benefits you may expect from your
Aprilaire®Air Cleaner. This booklet is furnished to acquaint
you with these benefits, and with operation and maintenance
information to insure the high level of performance this high
efficiency air cleaner is designed to provide.
PERFORMANCE
Air cleaners are effective only when air is circulated
through them. So, it is unrealistic to expect complete removal
of all contaminants. However, the efficiency of the Aprilaire®
Air Cleaner actually increases with use, and removes a very
high percentage of the pollutants from the circulated air.
There is pollution in air everywhere — even in the air we
normally consider fresh outdoor air. The infiltration of outside
air into the home is minimized by keeping doors and
windows closed as much as possible, therefore, increasing
the indoor air quality.
You may have purchased your air cleaner for allergy
relief. Allergy cases differ widely — and the Aprilaire®Air
Cleaner is not a sure cure for any allergy. However, if you
suffer from allergies caused by pollen, mold, spores, dust
and other airborne allergens, this efficient air cleaner can be
highly beneficial because it removes up to 99% of these
pollutants from the air passing through it.
The reduction of household dust, tobacco smoke
particulate and smudging particles may have been the
motivating influence in your decision to have an air cleaner
installed. The Aprilaire®Air Cleaner removal efficiency of

these very fine particles and pollutants reaches up to 95%. It
follows, then, that since there are less of these particles in the
air, you may expect a reduction in the necessity for dusting
and cleaning and a longer time interval between
redecorating.
Particle sizes of pollutants vary and are measured in
microns. A micron is 1/25,400th of an inch. A commonly used
illustration of their size is that it would take 200 microns to
reach across a dot made by a sharp pencil. The
accompanying chart shows the range of sizes, in microns, of
the most common pollutants.

OPERATION
Household dust is typically an accumulation of particles
in a size range of .01 micron (1/2,540,000th of an inch —
invisible to the naked eye) up to 100 microns (the diameter of
a human hair). Pollens and spores, which can aggravate
allergy symptoms, are usually in the 10-100 micron size
range.
The efficiency of the Aprilaire®Air Cleaner Media on the
smallest particle which can be seen with the naked eye
(approximately 10 microns) reaches 99%.

The visible household dust particles, and nearly all pollen
and spore particles, therefore, can be caught and
permanently held, very easily, if you can get them to the air
cleaner. With central high efficiency air cleaners, the blower
of your heating/air conditioning system performs the air
movement function.
Continuous air cleaning will be accomplished when your
thermostat is set for continuous air circulation. If continuous
air cleaning is not required, or desired, you can manually set
your control for any time period you desire. Many
thermostats have a switch position for manual fan.
“Automatic” turns on the blower only when heating or cooling
is required. “Fan” or “manual” allows you to control blower
operation.
For those who choose periodic cleaning, (as opposed to
continuous cleaning through continuous furnace blower
operation), the most important period is during — and for
several hours after — vacuuming your home. The vacuuming
process (unless you have a central vacuum system) stirs up
a large volume of dust particles which must be drawn into
your air cleaner.
Many of the dust particles generated, while vacuuming,
are so heavy they “fall” out of the airstream before they can
be drawn out of your living area. This is why it is important to
do household dusting several hours after vacuuming.
Normally once the heavy particles “fall out”, they are only
reintroduced to the air by vacuuming, or similarly vigorous
activity.
Where allergy symptoms, which are aggravated by
pollens and spores, are a concern, continuous cleaning is
strongly encouraged.
To recap, when removing household dust is the major
benefit you are seeking, you should operate your air cleaner
during and following periods when dust is being generated or
“stirred up”. For pollens and spores which aggravate an
allergy condition, your cleaner must be operated
continuously when these pollutants are in the environment.
The air cleaner can only be effective when air containing the
contaminants is drawn through the high efficiency media.

MAINTENANCE
The Aprilaire®Air Cleaner requires no electrical component
service, generates no ozone, and is not affected by
relative humidity or temperature. The only maintenance
required is the periodic replacement of the disposable
Aprilaire®Media which the homeowner can do in a few min-
utes. The frequency of replacement will vary with operation
time, the amount of pollution generated in the home and is
affected by: number of people and their activities, the
amount of carpeting, pets, size of home, number of smokers,
the pollution level of the area. We recommend replacing the
media each year. However, if you do not run your blower con-
tinuously (24 hours per day, 365 days per year) the media
may last up to two years. Air conditioning systems larger than
3.5 tons, or heating systems larger than 130,000 BTU’s per
hour (1400 cfm), will require more frequent attention if oper-
ated continuously.
Always remember that your Aprilaire®Air Cleaner Media is
at its lowest efficiency point when it is new. Efficiency
increases with usage. There is no efficiency or performance
benefit from replacing your media too often.
To obtain service parts and/or replacement media,
please proceed as follows:
• Call the installer of your APRILAIRE®.This
information is often found on your equipment.
• Call your heating and air conditioning contractor.
• Look for the APRILAIRE®logo in TheYellow Pages
under air cleaning & purifying equipment.
• Look in TheYellow Pages under heating and air
conditioning contractors. Any contractor can order
service parts or media replacements for you.
Detailed instructions on the easy replacement of the
Aprilaire®Media are furnished with each replacement media.
