If I don't have
alleriges, why do I need an air cleaner?
The EPA says that indoor air is on average 7-10 times worse than outdoor
air, even if you live in a city. Air has a direct pathway into our
bodies and a direct effect on our health and well being. Besides
allergies, poor air quality is linked to a number of problems: fatigue,
asthma, respiratory ailment, the spread of flu and other diseases, and
even cancer.
What's wrong
with the furnace filters that I buy at the hardware store?
A furnace filter is just that: a filter to help your furnace equipment
stay clean. In fact, most filters are in most heating and coolings
systems to protect the equipment not the people. They do almost
nothing to improve the air quality from a health standpoint.
What about a
room air cleaner?
Most supplemental room air cleaners can help clean
the air in a room or two. However, by installing an air cleaner in
your home's central forced air system, you will clean the entire house.
Further, many room air cleaners use high-efficiency passive filters, which
require powerful - and therfore loud - fans to move the air. This
can be an annoyance.
Why not buy
one of those filters advertised on the radio by Paul Harvey or Rush Limbaugh?
These are called passive electrostatic filters.
Their fibers have a slight static charge. As airborne particles move
through them, they can be attracted to the fibers, the way rubbing a balloon
on a sweater will make it stick. They are better than the $2 throwaway
1" filters, but they can cause some problems in residential systems.
As a passive electrostatic filter load up with contaminants, its fibers
become coated with particles and the "balloon effect" stops. This
can happen quickly and then the filter is only effective against larger
particles in the air, over 5.0 microns. Further, in order for a passive
electrostatic filter to work, it must be dense and therefore restrictive
to airflow. In many homes this can cause poor heating and cooling
in the upper level of the home or in the rooms farthest from the air handling
equipment. As the filter loads up, it becomes even more restrictive.
This not only makes the air conditioning equipment work inefficiently,
but can actually do damage. In fact, some electric utilities tell
their customers not to use passive electrostatic filters. Because
Dynamic Air Cleaners use a controlled high voltage/low amp charge to create
an active electrostatic field inside the Dynamic Panel, they are able to
use a very sparse media that is not restrictive to airflow or furnace equipment.
Dynamic Air Cleaners also improve in efficiency as they operate, while
capturing the very smallest particles in the air such as bacteria, smoke,
mold spores, pollen and many more. In a residential furnace system,
like the one in your home, a Dynamic Air Cleaner collects over 97% of the
particles that are 0>3 microns and larger!
What is a micron
& why should I care about small particles?
A micron is 1/25000th of an inch. A human hair
is about 150 microns; the smallest thing that can be seen with the naked
eye is about 10 microns. It is the largest particles, above 5.0 microns,
that cause equipment problems and are what most filters are able to catch.
However,
98% of the particles in the air are smaller than 1.0 micron. These
"sub-micron" particles are not caught by most filters and can get through
our bodies' natural defenses when inhaled. Further, they can
stay suspended in the air for days until they are breathed in. An
increasing number of studies have found these sub-micron particles to be
a significant health hazard. As an allergy sufferer can tell you,
what you can't see can hurt you. To effectively clean the air the
sub-micron particles must be removed. Dynamic Air Cleaners will
remove up to 98% of these particles on a multiple pass basis. For
example, when tested by the Canadian Department of Health & Welfare
in a test house, after 10 hours of operation, a Dynamic Air Cleaner was
able to remove 97% of the particles in the 0.3-0.5 micron range and
99% of the particles larger than 0>5 microns. Efficiency actually
increases as the Dynamic Air Cleaner loads with pollutants.
Does the Dynamic
Air Cleaner create a snapping sound or produce ozone?
No. Dynamic Air Cleaners are a non-ionizing
air cleaner that creates no nuisance noises or produces harmful Ozone.
Rather than ionizing, Dynamic Air Cleaners operate by assigning polarity
to both the particles and in the air and the fibers of the media pad.
This gives each a negative pose and a positive pose, essentially turning
them into magnets. The particles are then attracted to other particles
(making them easier to catch) and to the media fibers. Just as paper
clips on a magnet attract other paper clips, the dirt captured becomes
part of the collecting surface, giving the air cleaner increasing efficiency
as it loads.
I have had an
electronic air cleaner before and noticed a thin coat of dust on a lot
of surfaces, especially on my TV screen. Will this air cleaner do the same
thing?
No. Dynamics do not create charged particles that
will cling to grounded surfaces in the home. Electronic air cleaners
to date have worked by ionizing (positively charging) the particles in
the air. Dynamic Air Cleaners are a NON-IONIZING patented technology.
They then try to capture them on negatively charged or grounded collection
plates. This works fairly well at initially, but as the plates load
up with positive particles, they lose their attraction quickly and the
ionizing air cleaner loses its efficiency. The positively charged
particles then will stick to any grounded (walls and ductwork) or charged
(a TV screen) surface.
Is the Dynamic
Air Cleaner hard to install?
Not at all. In most homes, Dynamic Air Cleaners
will install in the standard existing 1" filter slot. In a few cases,
a filter track may need to be installed. The additional cost for
this rack will be about $50 from most contractors. Dynamic Air Cleaners
require a 24 volt power input. This can be taken either off the 24
volt system of your furnace or from a plug-in transformer supplied by Dynamic
Air Cleaners Inc.
I currently
have an electronic air cleaner, does it need to be removed?
No. A Dynamic Air Cleaner can fit right into
where the existing two main cells currently are located. A spacer
will need to be installed to provide a 1" track and the power to the old
air cleaner should be turned off or disconnected. This type of retrofit
generally takes a 20"x25" Dynamic Air Cleaner and works very well.
To check this, measure the size of the two cells side by side.
What is involved
in the maintenance of the Dynamic and how often must it be done?
This will vary a little from home to home. Generally,
we recommend that the media be changed 3 times a year sometime more often
depending on your environment. The media pad is disposable and changing
it takes only a couple of minutes. When changing the media, you should
also check for face-loaded dust on the Panel's outer screens. If
this has built up, it can be brushed or vacuumed off.
Can I use any
media?
No. Dynamic Air Cleaners will not work with
standard filter medias. While our pad may looks similar to a plain
fibre media, if you look closely you will see that there is an activated
carbon center screen bonded into it. This patented configuration
not only absorbs odors, but also conducts the electrical charge that creates
the polarizing field. Standard media is not capable of doing this.
Is the replacement
media expensive?
No. It costs about $5 a month to insure clean,
fresh, safe, healthy air in your home. And when compared to the time
and expense of other so called 'high efficiency' alternatives, it is very
economical. Electronic ionizing air cleaners must be cleaned regularly.
Their manufacturers tell you to wash it in the dishwasher, while dishwasher
manufacturers will tell you not to! This means you must take the
cells to a car wash or have a service clean them. The cells should
also be chemically stripped each year, which generally costs about $50.
If the unit is equipped with a carbon panel for odor control, these can
cost $100 to $160 per year to replace. High effeciency passive filters,
such as HEPA's cost hundreds of dollars to replace and may also have carbon
inserts that further add to the cost. All this for a system which is nowhere
as practical and effective as a Dynamic Air Cleaner. Now you can see why
we call it "The NEXT Generation In Air Filtration".
How do I know
my air cleaner size?
Slide out your current furnace air filter; the size
should be written on the side of it. If your filter is media only
and does not indicate the size, measure the media. If you have a
filter that is wrapped around the bottom of the air handler, please call
for instructions.
How long has
the Dynamic Air Cleaner been around?
Dynamic Air Cleaners have been manufactured for over
twelve years and used extensively in Canada, Japan, and commercial applications
around the world. They are used in "clean" manufacturing, casinos,
hospitals, and food processing and are available to clean the air that
is most important to you - the air that you and your family breathe.
How should
we operate the Dynamic Air Cleaner?
Any air cleaner can only be effective if air is moving
through it. Therefore in most areas, for maximum effectiveness, we
recommend that your thermostat be turned to the fan "on" position rather
than the "auto" position. This will give continuous air cleaning.
This takes only a small amount of electricity, but makes a significant
difference in the air quality in your home. It will also greatly
reduce the amount of dusting required in your home. Otherwise, the
Dynamic Air Cleaner will only be cleaning when you are heating or cooling.
In the spring and fall when your air conditioning system is not on very
often, you won't be cleaning the air very often either. The only
exception to the "fan on" recommendation is in very high humidity areas.
If you live in such an area, please consult your Dynamic dealer for operating
recommendations.
